Product details

The 20R-JMCS-G-B-TF(NSA) is a JST JMC series receptacle with center strip contacts, 20 positions in a dual-row layout at 0.020" (0.50mm) pitch. This is a fine-pitch, surface-mount connector designed for dense board-to-board or flex-to-board interconnects where space is tight — think compact handheld devices, camera modules, or battery management boards.

This part is marked Obsolete.

The 20 positions match a 20-circuit harness or a 20-pin board interface. The 0.091" (2.30mm) height above board determines the z-height budget when mated with a JMC series header; you'll need the header's mated height to confirm the stack clearance. Gold contact finish handles repeated mating cycles better than tin, but without a specified cycle count, treat it as moderate-duty.

It is a surface-mount termination — no through-holes, so the board must have SMT pads aligned to the 0.50mm pitch. The board guide feature helps locate the connector during pick-and-place, reducing tombstoning risk. The tape-and-reel packaging suits automated assembly lines.

Frequently asked questions

What is the replacement for 20R-JMCS-G-B-TF(NSA)?

For a new design, look for a JMC series receptacle at the same 0.50mm pitch and 20 positions, but verify the footprint and height match your board.

What is the pitch of the 20R-JMCS connector?

The pitch is 0.020" (0.50mm). This fine pitch requires a precise SMT footprint and reflow soldering.

What is the height of 20R-JMCS-G-B-TF(NSA)?

The height above board is 0.091" (2.30mm). This sets the z-height clearance when mated with a JMC series header.

What connector mates with 20R-JMCS?

It mates with a JMC series header of the same 0.50mm pitch and 20-position count. The exact header order code depends on the mating height and mounting orientation required.
