Product details

What the 3 A Rating Means for Your Circuit

The BM05B-XASS-TF(LF)(SN): Tin-plated mating surfaces are suited for moderate-cycle applications — the contact finish limits repeated mate/unmate duty compared to gold.

The XA series offers 4-position (BM04B-XASS-TF(LF)(SN)) and 6-position (BM06B-XASS-TF(LF)(SN)) variants with identical pitch, current rating, and SMD footprint. The 5-position part fills the gap between them — useful when a harness needs exactly five circuits without wasting a position or requiring a second connector.

Frequently asked questions

Does BM05B-XASS-TF(LF)(SN) mate with JST XA series female housings?

Yes, this header is designed to mate with JST XA series crimp receptacles. The 2.50mm pitch, single-row layout, and locking ramp are standard for the series.

What is the closest functional alternative to BM05B-XASS-TF(LF)(SN)?

The BM05B-XASS-TF (without the (LF)(SN) suffix) is functionally identical — same 5 positions, 2.50mm pitch, SMD, tin plating. The (LF)(SN) denotes lead-free and tin-plated termination finish, so the non-suffix version may have different plating or packaging. Confirm the BOM requirement before substituting.
