The 75844-127-26LF is a 26-position, dual-row unshrouded BergStik breakaway header from FCI (now Amphenol ICC). It sits on the standard 0.100" (2.54mm) pitch — the de facto grid for legacy and new board-to-board and wire-to-board interconnects.
Rated 5A per contact, which is typical for a signal-level BergStik header on 0.100" pitch — the 5A figure is a per-contact limit under standard conditions, not a total for the connector. The 110V voltage rating is adequate for most logic-level and low-power DC buses inside equipment. The mating finish is 30.0µin (0.76µm) of Gold, GXT™ — a hard gold alloy that handles repeated mating cycles without wear-through, so this header holds up in field-service or test-fixture applications where the board gets plugged and unplugged more than a few times. Through-hole solder termination with a 0.105" (2.67mm) post length — the tail is short, meant for standard PCB thickness around 0.062" where the solder joint sits flush on the pad. The overall contact length is 0.465" (11.81mm), with a 0.260" (6.60mm) mating pin length that provides good wipe in the receptacle contact.
