Board footprint and position count
The B11B-PH-SM4-TB: This is an 11-position, single-row header on 2.00mm pitch — the pitch is the dimension that sets the pad spacing on your board, not a generic 'compact' claim.

No — this part is listed as RoHS non-compliant. If your BOM requires RoHS compliance, the closest functional alternative is B11B-PH-SM4-TB(LF)(SN), which shares the same pitch, position count, and shroud but is RoHS-compliant.
The mating pitch is 0.079" (2.00mm), single row.
This is a male pin header from the JST PH series, designed to mate with a PH-series crimp receptacle housing (sold separately). The detent lock engages with the matching housing latch.
