At 2.00 mm pitch, the 3-position header occupies a narrow 6.00 mm board footprint — a tight fit for space-constrained layouts. The 4-position sibling (S04B-PASK-2) shares the same pitch, current, and right-angle form factor — the only difference is one extra circuit. If the BOM calls for 3 positions, this is the correct part; the 4-position version will not fit a 3-position receptacle.
The S03B-PASK-2 is an active JST part, sourced through independent distribution.
The S03B-PASK-2 is a single-row, 3-position male pin header with all positions loaded. Pin 1 is typically identified by the polarisation notch or the square pad on the PCB footprint — consult the JST PA series drawing for the exact keying orientation.
The S03B-PASK-2 mates with a JST PA series 3-position receptacle housing (such as the PAP-03V-S) using the appropriate crimp terminals (e.g., SPHD-002T-P0.5). The locking ramp on the header engages the receptacle latch.
Yes, the S03B-PASK-2 is ROHS3 compliant.
