What does the (F) indicate at the end of the GHD series housing part numbers [i.e. GHDR-20V-S (F)]?

Modified in 2007, the (F) indicates the housing as a "finger friendly" style to improve handling during mating and unmating operations. Please refer to the following diagram:

What does the (N) indicate on part number SYM-001T-P0.6 (N)?

As an internal JST reference to control FIFO inventory, the (N) was applied to indicate a change in the quantity per reel from 7,500 pieces to 8,500 pieces.

The data sheets, product specifications and drawings will not indicate this internal reference though it is likely to be shown on the package labeling, packing lists and invoices to customers who purchase this item.

Please contact us here if you have further questions.

What does the suffixed (NSA) on the JMC series recepatacles indicate?

The (NSA) 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 as well as the inclusion of a Nickel stripe to help prevent solder from traveling up the contact during the reflow process. For more information contact us here for a handling manual of the series.

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.
