In a quarterly maintenance schedule, that translates to decades of reliable reconnection.
Active Production, RoHS Non-Compliant — Plan Accordingly
The phosphor bronze contacts with 30 µinch gold finish are standard for signal-level current (typically 3 A per contact, derated per the series application note).
How 69168-108 Compares to the 6-Position Sibling
The closest functional alternative is the 69168-106 (6 positions) or 69168-106HLF — same pitch, same friction lock, same gold plating, same overall contact length of 0.300" (7.62 mm) vs. 0.400" (10.16 mm) on the 8-position. The 69168-108HLF is a direct equivalent with the same 8 positions and 0.400" overall length — the HLF suffix typically indicates a lead-free (RoHS-compliant) version. If RoHS compliance is required, the HLF variant is the drop-in replacement.
