The difference is the width of the contact lance. The “A” style is the latest version with a lance that is about twice the width of the original contact (without the “A”).
The contact was modified and went into effect in April 2003 to improve contact retention within the housing and to help prevent accidental extraction and slippage of the contact from the housing.
As the contact lance has been modified, so has the applicable housing. The housing to be used with contact SBHS-002T-P0.5A is part number BHSR-02VS-1(N); the (N) indicates a modification of the housing lance to accommodate the contact with the modified lance.

Please contact us here if you have any questions.
The FDZ series incorporates a sliding lock mechanism (slider) to lock the applicable FPC into the connector. Prior to the year 2000, the FDZ series was packaged and shipped with the slider in the open position.
Shipping in this method may cause the slider to break and / or damage the connector.
It was decided to package and ship the slider in the semi-locked position to help prevent breakage during packaging and shipping processes. To distinguish the new method from the old for first in, first out (FIFO) inventory control, an (S) was added to the suffix of the applicable parts.
Since 2000, only the parts with the incorporated (S) in the part number can be ordered. An example of the part number would be 13FDZ-BT (S)(LF)(SN).
The part is no longer provided with the slider in the open position from the factory [without the (S)].
If you have additional questions please contact us here.
The difference is the material to conform to RoHS compliance.
The older SM1 / RSM1 are of 46 Nylon. The compliant SM2 / RSM2 are of Glass-filled PA6T Nylon. These better withstand the higher temperatures required for the lead free solder reflow process.
For more information please contact us here.
The (P) or (PP) suffixed to the part number is an internal reference for JST. The (P) or (PP) indicates a change made to the inner and outer package labeling. It does not affect the physical part and it will not be shown on the product specifications.
When purchasing some JST part numbers, you may find added characters and letters added to the prefix or the suffix of the part number as designated by our factories and sales offices.
Prefixed characters indicate the factory of origin while suffixed characters may indicate RoHS compliance and/or internal JST changes (i.e. change in raw material supplier). Any internal changes denoted in the suffix do not affect part fit, form or function. The following common prefixed characters would indicate the factory / country of origin. If there is no character prefixed to the part number, the country of origin is Japan: (G) = Shanghai, China (W) = Indonesia (C) = Waukegan, Illinois, USA (Q) = Korea (D) = Malaysia (B) = Belgium The following suffixed characters would indicate the part number is RoHS compliant. These typically apply to PCB mounted headers. The majority of housings and contacts are RoHS compliant as is and do not require these added characters. Please contact your JST sales representative to confirm RoHS compliance if you are uncertain: (LF) = Lead-free. The finish would be 98% tin and 2% copper. (LF)(SN) = Lead-free with a 100% pure tin finish [SN is the Periodic Table of Elements symbol for tin]. (LF)(AU) = Lead-free with a 100% gold finish [AU is the Periodic Table of Elements symbol for gold]. The gold finish would have a nickel underplate. Other characters, such as (S), (N), (M), etc., would indicate modifications to the part, changes in the raw material supplier at the factory, or packaging. These characters differ from part to part and series to series. For details on such characters, please contact your JST sales representative.
The majority of JST through-hole type header wafer materials cannot withstand the temperatures required for reflow soldering (pin-n-paste). The through-hole headers are designed for wave or dip soldering methods.
Please contact us here if more information is required.
Used on surface mount, through-hole headers and board-in connectors, a “boss” is a peg on the bottom of a header that helps polarize and situate the product onto the PCB.
For polarization, the boss allows the user to orient the product onto the PCB in only one direction. They are also used to help steady surface mount headers before subjecting them to IR reflow.
An extra hole is required to be drilled /punched into the PCB when incorporating items with bosses though the boss typically will not penetrate completely through the PCB like a through-hole solder tail would.

Part number SSH-003T-P0.2-H is a newer version and is called a “high-pressure contact type” compared to the older SSH-003T-P0.2. The contact point of the contact was modified for a more assured connection and to help prevent the contact from warping when mating with the header posts.
Both contacts share the same application crimp tooling for terminating to the applicable wire. For more information, please visit www.jst.com.
At this time, the SH series is only offered in its current configuration of wire-to-board. A wire-to-wire application option is not available.
Replace ( ) with the applicable number of circuits.
The “C” indicates the inclusion of a removable suction cap used for the ease of placement using pick and place equipment vacuum nozzles. Unlike Kapton tape applied to many of our SMT products, the “C” on this series is a hard plastic cap.
For details or further information please contact us here.
A housing for this terminal is not supplied by JST. It is left to the decision of the end user to use a housing with this terminal.
The “P” indicates the base material. With the “P” the material is Phosphor Bronze. Without the “P” the material is Brass.
JST does not typically offer our strip terminals and chain terminals in loose piece (bulk) packaging. The reeled terminals are designed for large volume semi-automatic and fully-automatic wire termination equipment.
Hand tools are offered for loose contacts but most require the user to cut the terminal or contact off of the carrier strip before placing it into the hand tool for crimping.
Some of the JST authorized distributors do have the capabilities of removing the contacts from the carrier strip for those who wish to purchase loose contacts. Our network of authorized distributors can be found here.
For some of the connector series’, the top-entry surface mount headers require a suction cap for pick-n-place equipment vacuum nozzles. As such, those for which it applies would have an extra “T” suffix to the part number. For example, to have part number BM06B-SRSS-TB include the suction cap, it would be ordered as BM06B-SRSS-TBT. The same would apply to most top-entry headers with a “-TF” suffix. The SHD series is the exception whereas it uses a hard plastic cap thereby the suffix would be “-TFC”. For more information please contact us here.
Will the WC-240 hand tool work with SPHD-002T-P0.5 as well as SPH-002T-P0.5S?
No. The subject hand tool will not work with SPHD-002T-P0.5.

The strip length is 3.0mm to 3.5mm (0.118″ to 0.138″).
The difference is the material. With the “P it is a Phosphor Bronze material and is the standard to use. Without the “P” the material is Brass.
The parts without the “N” incorporated in the part number may emit an unpleasant odor. In response to customer requests, the parts with the “N” use a raw material resin grade for the wafer material that incorporates countermeasures against the odor.
Without “N” part numbers in which an unpleasant odor may be present:
B( )B-XASK-1 (LF)(SN)
B( )B-XASK-1-A (LF)(SN)
With “N” part numbers that incorporate countermeasure against an odor:
B( )B-XASK-1N (LF)(SN)
