The S11B-XH-A-1(LF)(SN): The closest functional alternative is S11B-XH-A-1 — same 11 positions, same pitch, same tin finish, same right-angle orientation. The difference is the (LF)(SN) suffix on this part confirms lead-free and tin-plated contact finish; the non-suffixed version may carry a different plating or packaging variant. Confirm the BOM position before swapping.
Mating Connector and Wire Termination
Mates with JST XH series crimp-style receptacle housings (e.g., XHP-11) loaded with SXH-001T-P0.6 or equivalent tin-plated female terminals. Termination is press-fit, solder — the through-hole tails are 0.134" (3.40 mm) long, suited for a standard 1.6 mm PCB.
Position Count Comparison vs S12B-XH-A-1
If the BOM calls for 12 circuits, S12B-XH-A-1 adds one position at the same 2.50 mm pitch and same electrical ratings — the board footprint grows by 2.5 mm, and the mating housing changes to XHP-12. No other spec differs.
