24-Pin Breakaway Header at 0.100" Pitch
The 77313-122-24: The breakaway design lets you snap the strip to a shorter length if your BOM calls for fewer positions — though this part ships fully loaded at 24 circuits. The post finish is tin at 78.7 µinch (2.00 µm), which solders cleanly into plated through-holes.
Board Fit and Mating Half Check
The push-pull fastening type means there is no locking latch; vibration resistance depends on the mating connector's retention.
Obsolete — Sourcing and Replacement Planning
The 77313-122-24 is marked Obsolete by Amphenol ICC (FCI). No official successor or direct replacement part number is listed in the product record. For a BOM already using this header, the sourcing path is independent distribution — quantities are lot-specific and confirmed at RFQ. If you are designing a new board, consider a current-production BERGSTIK header with the same 0.100" pitch, dual-row, 24-position, unshrouded configuration. The base product number 77313 covers multiple plating and post-length variants; verify the contact finish and overall length against your mating half.
