What does the (S) indicate suffixed to the JMC series receptacles?

The (S) indicates a modification made to the guide ribs of the receptacle to help prevent breakage during accidental, slantwise mating cycles instead of the proper straight mating method. For more information contact us here for a handling manual of the series.

What does the (T) indicate for the PND series headers?

The (T) indicates the packaging.

(T): Tray packaging

The PND series headers are packaged in trays to help prevent damage to the solder tails and housing during shipping and handling and for use in some automated PCB placement equipment.

Example part number: B30B-PNDZS-1 (T)(LF)(SN)

For additional information please contact us here.

What does the (S) indicate for the FDZ series?

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)].

What is the difference in the XA series header part numbers with and without the “N”?

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)

B( )B-XASK-1N-A (LF)(SN)

Replace ( ) with the applicable number of circuits for the series.

(LF)(SN) is the RoHS compliant identifier.

Without “A” is without a locating / polarizing boss.

With “A” is with a locating / polarizing boss.

What does the (P) or (PP) signify at the end of a part number?

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.

What does the "C" indicate on part number BM( )B-SRDS-G-TFC?

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.

What is the difference between B**B-ZR-SM3-TF AND B**B-ZR-SM4-TF (LF)(SN)?

The difference is the housing / wafer material...

SM3 is made of 46 Nylon glass-filled
SM4 is made of PA 6T Nylon glass-filled and is the RoHS compliant version.

The SM4 is better than SM3 for the higher temperatures required for the lead-free solder reflow process.
