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.

For more information or additional questions, please contact your local JST sales rep (Rep or Distributor Search) or contact us here.

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.

For more information please contact us here.

What is the difference between ( )FLZ-(R)SM1-TB and ( )FLZ-(R)SM2-TB(LF)(SN)?

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.

What is the difference between SBHS-002T-P0.5 and SBHS-002T-P0.5A

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.

Crimp Specifications (crimp heights, strip lengths, tensile strengths)

Crimp specifications for many of the common crimp contacts and terminals are now available on our web site on the following menu selection. Application Tools and Specifications

When selecting this link, choose the "Crimp Style Connectors". From there, enter the exact contact part number or choose it from the alphabetical scroll list [Select Model Number (from list):] provided.

The results will provide the user with the tooling options as well as the crimp specifications at the bottom of the page.

If further information is required, or an item is not listed, please contact us here for more information.

Part number nomenclature not cataloged

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
(K) = Kurayoshi, Japan
(I) = Innosho, Japan
(U) = Utsunomiya, Japan
(K) = Yangsan, Korea
(A) = Guntersville, Alabama, USA
(V) = France
(X) = Germany
(O) = Oda, Japan

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.
