Obsolete — Sourcing and Replacement Path
The 1-1971818-4: This part carries an Obsolete lifecycle status from TE Connectivity. For BOM positions already in production, the only sourcing path is through independent surplus channels — quantities are lot-specific and confirmed at RFQ. If you are designing a new board, a pin-compatible alternative in the same pitch and circuit count will require a review of the mating half and board footprint.
Through-hole solder termination with a contact post length of 0.114" (2.90 mm) — this sets the board thickness and solder fillet geometry. The header is loaded with all 14 positions, so no blank positions to account for in the harness design.
