The 71991-302: The bottom or top entry designation means the receptacle can receive the header from either side of the board, useful for mezzanine or reverse-mount configurations. All 4 positions are loaded — no unpopulated pins to manage in the BOM.
No direct replacement exists — a board redesign may be required for continued production.
The 71991-302 is obsolete and sourced through independent distribution. Submit an RFQ for current availability and pricing — stock is lot-specific and confirmed at quote time. No direct factory stock or lead time applies.
