Product details

20-position dual-row header for 2.50mm wire-to-board

The B20B-XADSS-N: JST XAD series header, 20 positions loaded across two rows at 0.098" (2.50mm) pitch. The 0.138" (3.50mm) solder post length suits standard through-hole PCB thicknesses; the 13.8mm mated stack height leaves room for the mating socket body above the board.

Frequently asked questions

Is B20B-XADSS-N compatible with JST XAD series sockets?

Yes. The B20B-XADSS-N header is designed to mate with JST XAD series crimp sockets (female housings that accept the XAD crimp terminals). The locking ramp on the header engages the latch on the socket housing for a vibration-resistant connection.
