Board footprint and position count
The 2-188275-0: All 20 positions are loaded, meaning no dummy pins to track on the BOM — every contact carries signal or power.
Tin plating and mating cycle budget
Tin is the cost-optimised choice for low-cycle applications — expect roughly 50 mating cycles before contact resistance drifts. Not the right pick for a field-service connector that gets unmated quarterly. The forked contact geometry wipes the mating pin on insertion, which helps break through any tin-oxide film at first mate. That wipe action is built into the contact beam, not the plating grade.
Production status and sourcing posture
ROHS3 compliant.
Comparing against a black-housing sibling
The closest peer in the same Micro-MaTch series is 1-2823056-2: same 0.100" pitch, same forked contact, same SMD termination — but 12 positions instead of 20, and a black housing instead of red. For a 12-position BOM, 1-2823056-2 is a drop-in footprint match; for 20 positions, this is the only option in the series.
Housing material and temperature range
Glass-filled PA46 (Nylon 4/6) housing rated UL94 V-0 — the flame rating satisfies the enclosure requirement for equipment inside a cabinet.
