BM04B-ZESS-TBT is a 4-position, single-row surface-mount header from JST's ZE series, on 1.50 mm pitch — a tight enough pitch to save board real estate but still hand-solderable in rework. The tin-on-tin contact finish (mating and post) is cost-effective for applications that don't demand high mating-cycle counts; expect several dozen cycles before wear becomes a concern.
No — the listing shows RoHS non-compliant. If your BOM requires RoHS, the BM04B-ZESS-TBT(LF)(SN) is the direct functional equivalent with the same 4 positions, 1.50 mm pitch, and locking ramp, but marked RoHS compliant.
This is consistent across the ZE series SMT headers.
