Product details

Board footprint and pinout

The header is unshrouded, meaning the pins are exposed after mating — no plastic shroud to guide or key the receptacle. This is common for low-cost, low-density interconnects where the mating connector is a standard female socket housing.

Current and contact finish

Rated 3A per contact. Tin-plated mating surface (, 100µin thickness) is fine for occasional mating — expect around 50-100 cycles before the tin begins to fret in a high-vibration environment. LCP handles reflow temperatures well and resists moisture absorption, which matters for conformal-coated boards.

Termination is solder, through-hole. The post finish is tin (, 100µin) — solderable with standard rosin flux. No press-fit or IDC option on this part.

Frequently asked questions

What is the compatible mating connector for 5-146278-3?

Common mates include AMPMODU Mod II receptacles or generic 0.100" pitch crimp housings. The push-pull retention means no locking latch — ensure the receptacle has adequate contact retention force.
