Product details

What the 9 Circuits and 2.50 mm Pitch Mean for Your Board

The B09B-XASK-1(LF)(SN): 9 positions, single row, all loaded.

Locking Ramp and Tin-Plated Contacts

Tin-on-tin contact interface rated 3 A per circuit at 25°C; derate above 85°C ambient per the housing material limit.

Through-hole press-fit / solder termination. Mates with JST XA series receptacle housings using the locking ramp. Mated stack height is 11.3 mm — budget this in the enclosure z-height.

Peer Comparison: 8 vs 9 Positions

The B08B-XASK-1(LF)(SN) is identical in pitch, current, and plating but carries 8 circuits instead of 9. If your harness needs one less signal, that sibling saves a position without a board respin.
