Product details

10.00mm Pitch Right-Angle Header with Board Lock

The 0428204234: Silver-plated male blade contacts (100.0µin silver over copper zirconium alloy) handle repeated mating cycles in power circuits — silver carries higher current than tin at the same temperature rise, and the 100.0µin thickness provides a durable wear surface for field-service reconnect duty.

The shrouded 4-wall housing prevents misalignment during mating.

Available in tube packaging. The base product number 042820 covers the series; the full 0428204234 suffix specifies the 4-position, right-angle, silver-plated variant.

Frequently asked questions

What is the pitch of Molex 0428204234?

The mating pitch is 0.394" (10.00mm).

Does the 0428204234 have a locking ramp?

Yes, the header uses a locking ramp fastening type. The ramp engages with the mating receptacle housing for a vibration-resistant, audible-latch connection.

What is the current rating of Mini-Fit Sr header 0428204234?

The Mini-Fit Sr series is rated for high-current power applications. The silver-plated blade contacts (100.0µin silver) carry higher current than equivalent tin-plated contacts — the exact per-circuit rating depends on wire gauge, ambient temperature, and number of circuits powered simultaneously. Consult the series derating curve for your specific load conditions.
