The ICA-308-STT: The 18-position ICA-318-STT shares the same tin finish, 0.100" pitch, and through-hole solder termination, differing only in position count.
The ICA-308-SST is the same 8-position DIP socket with gold-plated mating contacts (10.0µin) instead of tin; the footprint, pitch, and termination are identical.
The ICA-308-STT is ROHS3 Compliant per Samtec's lifecycle record.
