Frequently asked questions
Where can I buy B13B-XASK-1-A(LF)(SN) available via RFQ confirmation?
No stock-holding claim is made; submit an RFQ for a firm commitment.
What is the pitch of B13B-XASK-1-A(LF)(SN)?
The mating pitch is 0.098" (2.50 mm), single-row, 13 positions.
Is B13B-XASK-1-A(LF)(SN) RoHS compliant?
Yes, it carries RoHS compliance.
What is the mating connector for B13B-XASK-1-A(LF)(SN)?
This header mates with the JST XA series receptacle housing (e.g., XARP-13V or similar) that accepts the appropriate crimp terminals. The locking ramp and 2.50 mm pitch are the key compatibility checks.
What are alternatives to B13B-XASK-1-A(LF)(SN)?
The closest functional alternative is the non-LF version B13B-XASK-1-A (same form, fit, and function, but without the RoHS suffix). For a different position count, the 14-position B14B-XASK-1-A(LF)(SN) shares the same pitch, current rating, and locking ramp.
