The Amphenol ICC 67998-234HLF is a 34-position, dual-row unshrouded header from the BERGSTIK® II series. It's a through-hole, solder-terminated board-to-board interconnect built around the industry-standard 0.100" (2.54mm) pitch. The 15.0µin gold plating on the mating surface gives it the cycle life for repeated mating in production or field service, while the phosphor bronze contacts carry a solid 5A per circuit. The UL94 V-0 black insulation handles the flame-rating requirement for equipment inside an enclosure.
What the Ratings Mean for Your Fit
The 0.100" pitch is the standard spacing for prototyping and legacy designs. The 5A per contact rating is real power capability for a signal header.
Board Layout and Mating
This is an unshrouded header — no plastic wall around the pins — so the mating receptacle needs its own alignment features. The 0.100" row spacing matches the standard BergStik II footprint, and the 0.107" post length (2.71mm) is sized for a standard 0.062" PCB. The overall contact length of 0.525" (13.34mm) gives you enough tail to solder through a plated through-hole without bottoming out. The push-pull fastening type means no latch; the retention comes entirely from the contact friction fit with the mating receptacle.
