4-Pin, 4.20mm Pitch, Glow Wire Rated Header
The 10127820-0422LLF is a 4-position, dual-row, through-hole header from the Minitek® Pwr 4.2 series, with a 4.20mm pitch and a shrouded 4-wall housing that guides the mating receptacle and prevents misalignment during assembly. The header is Glow Wire Compliant per IEC 60335-1, meaning the LCP housing and tin-plated contacts resist ignition under fault conditions — a requirement for household appliances and commercial equipment that must pass a glow-wire test.
Glow Wire vs Standard: Choosing the Right Suffix
Within the same 10127820 base number, the -0422LLF (this part) is the Glow Wire Compliant version. The sibling -0422LF is identical in every other spec — same pitch, positions, plating, locking ramp, and UL94 V-0 rating — but lacks the Glow Wire feature. If your application does not require Glow Wire certification, the -0422LF is a direct drop-in alternative. If it does, the -0422LLF is the correct choice — no other spec differences exist between the two. A 6-position variant (10127820-0622LF) is also available in the same series for higher circuit-count needs, sharing the same pitch, plating, and locking ramp.
