Product details

Current and Voltage: Signal-Level Duty

The 2355045-4: The 2 A ceiling is typical for 2.00 mm pitch headers with gold flash contacts; derate above 85 °C ambient per the standard AMPMODU derating curve. Gold mating finish at 3.94 µinch (0.100 µm) thickness — a flash grade that provides corrosion resistance for moderate mating cycles (50–100 cycles typical) in controlled environments. For higher cycle life or corrosive atmospheres, the 8.00 µinch gold option on the 1376779-2 peer is a better fit.

Peer Comparison: 1376779-2 vs 2355045-4

The 8.00 µinch gold supports more mating cycles — a meaningful upgrade for field-service or repeated disconnect applications.

Frequently asked questions

What is the mating connector for 2355045-4?

The mating half must provide its own polarization and latch — the header has push-pull fastening only.

What is the closest alternative to 2355045-4?

The 1376779-2 is the closest functional second-source: same pitch, position count, and footprint, but with thicker gold plating (8.00 µinch) and a higher current rating (3 A). It is a direct cross-shop candidate for applications needing more mating cycles.
