Product details

Header Identity and Series Fit

The 0444321201: Rated for board-to-board or cable applications, this header supports general-purpose, medical, military, and telecommunications equipment.

Termination and Board-Mount Details

Termination is press-fit with a solder option — the press-fit compliant pin compresses into a plated through-hole, creating a gas-tight connection without reflow. This is the preferred method for backplane and high-reliability assemblies where solder joint fatigue is a risk under thermal cycling or vibration. Mounting is through-hole, vertical orientation.

Blind-Mate and Alignment Features

Blind-mate capability and integral board guides are built into the shroud. These features simplify connector alignment in multi-connector backplane panels where the operator cannot see the mating face during insertion.

Frequently asked questions

What is the pitch and mounting type of 0444321201?
