Amphenol ICC (FCI) has marked the 71991-325 as Obsolete. Stock is sourced through independent surplus channels; quantities and lead time are confirmed at RFQ. No pin-compatible direct replacement has been documented — any functional cross would require a board spin.
No official successor is listed. A pin-compatible replacement would need to match the 50-position, 2-row, 2.54 mm pitch, through-hole footprint.
