Product details

The 0022288202: The 20 positions are fully loaded, so the BOM line matches the circuit count exactly. The breakaway feature (part of the 42377 series) allows snapping to shorter lengths if needed, though this unit ships as a 20-position stick.

Contact Interface and Durability

In a test or programming fixture where the connector is cycled weekly, the gold layer resists oxidation and maintains contact resistance below the tin-plating threshold. The post finish is tin, 100.0 µinch (2.54 µm) — standard for solder-joint reliability. The square male pin (0.025" square typical for the series) mates with KK254 crimp or IDC receptacles.

Compliance and Application Range

UL94 V-0 glass-filled nylon housing — rated for flammability in equipment enclosures. The connector is listed for Automotive, General Purpose, Medical, and Telecommunications applications, covering both board-to-board and cable-to-board interconnects.

Frequently asked questions

What is the pitch of Molex 0022288202?

The mating pitch is 0.100" (2.54 mm), standard for the KK254 series and compatible with 0.100-inch grid PCBs.

Is 0022288202 shrouded or unshrouded?

Unshrouded — the header has no plastic shroud around the pins, so the mating receptacle provides the mechanical retention.

Does 0022288202 have a breakaway feature?

Yes, it is a breakaway header from the 42377 series. The 20-position stick can be snapped to shorter lengths if needed, though it ships as a full 20-position unit.

What is the mating connector for 0022288202?

It mates with KK254 series crimp or IDC receptacles (single-row, 0.100" pitch). Common mating housings include Molex 50-57-9420 or 22-01-3207 for the 20-position version.
