Product details

Mated Stack Height and Z-Budget

Mated stack height is 8.8 mm with the matching PHD receptacle. If your enclosure has a z-height constraint below 8.8 mm, this header won't fit; the PHD series does not offer a low-profile variant.

The B20B-PHDSS(LF)(SN) sits at 20 positions. Direct siblings include the 22-position B22B-PHDSS and the 24-position B24B-PHDSS(LF)(SN) — same current, voltage, stack height, and shroud. If your BOM calls for 20 circuits, this is the one; if you need 22 or 24, the pinout shifts by one pair per row, so the board layout changes.

Frequently asked questions

What is the mating connector for B20B-PHDSS(LF)(SN)?

This header mates with a JST PHD series receptacle housing (female crimp socket). The receptacle is a two-row, 20-position, 2.00 mm pitch housing that accepts the matching crimp terminals.
