Product details

24-Circuit Dual-Row Header at 4.20mm Pitch

The 0039289248: This Molex Mini-Fit Jr 5566 series header carries 24 circuits in a dual-row layout at 4.20mm pitch — the standard footprint for medium-current wire-to-board power distribution in industrial and telecom equipment.

Board Lock and Through-Hole Termination

Through-hole solder termination with 0.138" (3.50mm) post length provides a robust mechanical bond to the PCB — the solder joint carries the mechanical load, not just the electrical connection. The 0.165" (4.20mm) row spacing matches the pitch, keeping the board layout symmetrical and simplifying trace routing between rows.

30 µinch Gold Mating Finish for Field-Service Duty

Brass contact material with square pin geometry delivers consistent normal force across the mating interface, maintaining low contact resistance over the connector's service life.

Frequently asked questions

What is the pitch of Molex 0039289248?
