Product details

The 0.50mm pitch trap — why this plug is a board-layout puzzle

The JST 20PS-JMCS-G-1B-TF(N)(LF)(SN) is the 20-position plug half of the JMC series, built on a 0.020" (0.50mm) pitch. It's a right-angle surface-mount plug with outer shroud contacts, meaning it mates with a JMC receptacle that carries inner contacts. Gold plating on the contacts suits it for signal-level interconnect where moderate mating cycle life matters, not power duty.

This part is officially obsolete. No successor order code is listed on record, so there's no direct drop-in from JST. No official cross-reference to a JST 20PS-JMCS-G-1C or any other specific replacement is on record.

This is the plug with outer shroud contacts, so it mates with a JMC series receptacle that has inner contacts — same 0.50mm pitch, same 20 positions. No crimp terminals here — this is a direct-solder interface, so the board footprint and stencil design for the 0.50mm pitch pads are what determine joint reliability.

Frequently asked questions

What is the replacement for 20PS-JMCS-G-1B-TF(N)(LF)(SN)?

For an existing design, source through independent distribution. For a new design, check the current JMC series offerings at the same 0.50mm pitch and 20 positions.

What is the mating connector for the 20PS-JMCS series?
