Product details

Board-to-Board Header, 50 Positions, 0.100" Pitch

It is a board-to-board interconnect component designed for through-hole soldering to a PCB. The 0.100" (2.54mm) pitch on both rows and between rows matches the standard 0.1-inch grid, making it a direct fit for legacy and current PCB layouts that use this spacing. With all 50 positions loaded, this header provides a full complement of square pins for dense signal or low-power distribution.

The overall contact length of 0.410" (10.41mm) comprises a 0.190" (4.83mm) mating length and a 0.120" (3.05mm) solder tail. The through-hole termination requires a PCB with 0.025" to 0.030" plated-through holes on a 0.100" grid.

Contacts are phosphor bronze with tin plating. The base product number is 79425, and this variant (450) denotes the specific plating and tail length combination.

Frequently asked questions

What is the pin count of 79425-450HLF?

The 79425-450HLF has 50 positions in a dual-row configuration, with all positions loaded.

What is the current rating for 79425-450HLF?

The 79425-450HLF is rated 5 A per contact at 110 V. This is per-pin rating; total current depends on the number of circuits used and the PCB layout.

What mating connector works with 79425-450HLF?

The 79425-450HLF mates with any standard 0.100" pitch dual-row female socket or IDC receptacle designed for 0.025" square pins. It is an unshrouded header, so the mating connector must provide its own polarization or keying.
