Product details

6-Circuit Vertical Header with Locking Ramp

The 0039299067: This Molex Mini-Fit Jr 5566 header is a 6-position, dual-row, vertical through-hole connector with a 4.20mm pitch.

Pitch, Plating, and Contact Finish

The contact material is brass, and the square pin shape (0.062" typical for the series) provides a reliable gas-tight interface with the receptacle's dual-beam contact.

This header mates with Mini-Fit Jr 5557 receptacle housings and 5556 crimp terminals (20-24 AWG). Row spacing is also 4.20mm, matching the pitch for consistent routing.

ROHS3 compliant. The base product number is 003929; this specific variant is the 6-position, dual-row, vertical, tin-plated configuration in tray packaging.
