Product details

Board Fit and Circuit Count

The 93944-424HLF: All 24 positions are loaded, so the BOM circuit count matches the pin count exactly.

Current, Temperature, and Contact Finish

Rated 3A per contact, with the current ceiling limited by the temperature rise through the phosphor bronze contact and the tin-plated interface. The operating temperature range spans -65°C to 130°C, covering most industrial and automotive environments without derating at the low end. The post finish is tin as well, compatible with standard solder processes.

Mounting and Mechanical Details

Through-hole termination with a 0.130" (3.30mm) post length — the solder tail protrudes below the board for wave or hand soldering. Insulation height is 0.100" (2.54mm), keeping the profile low for tight board-to-board stacking.

Frequently asked questions

What is the pinout for 93944-424HLF?

Single-row, 24 positions, all loaded. Pin 1 is typically marked by a square pad on the PCB footprint or a chamfer on the header body. The unshrouded design means no keying — verify orientation against the mating receptacle.

Can 93944-424HLF be used with 2.54mm pitch?

Yes — the mating pitch is 0.100" (2.54mm), so it fits standard 0.100" grid receptacles and PCB layouts.
