Product details

The BM05B-GHS-TBT is a 5-position, single-row surface-mount header from JST's GH series, on a 1.25mm pitch. It mates with GH series crimp receptacles (e.g., GHR-05V-S) to form a wire-to-board connection. The shrouded 4-wall design and locking ramp secure the mating pair against vibration-induced disconnection.

SMT assembly and retention

Mated stacking height is 7.3mm, which sets the board-to-cable clearance in the final assembly.

Position count vs. sibling

The closest functional sibling is the BM06B-GHS-TBT, which shares the same pitch, current rating, voltage, locking ramp, and SMT features but carries 6 positions instead of 5. Both use the same GH series receptacle family — the difference is purely the circuit count on the board.

Frequently asked questions

What is the pitch of the BM05B-GHS-TBT?

The pitch is 0.049" (1.25mm), which is the center-to-center spacing between adjacent pins.

Does the BM05B-GHS-TBT support pick-and-place assembly?

Yes, the header includes a pick-and-place feature and solder retention, making it suitable for automated SMT placement and reflow soldering.

What is the closest functional second-source for the BM05B-GHS-TBT?

The BM05B-GHS-TBT(LF)(SN)(N) is a functionally identical variant — same pitch, positions, current, voltage, locking ramp, and SMT features — differing only in packaging or lead-free marking. Confirm the exact BOM requirement before substituting.
