Contact Interface and Durability
The 2355186-8: The post finish is 78.7 µinch (2.00 µm) tin — a standard solderable tail for through-hole wave or hand solder.
ROHS3 compliant. The base product number is 2355186 — the -8 suffix denotes the 8-position variant in this breakaway series.
Peer Comparison: 1376779-2
The key difference: 1376779-2 carries 3 A per contact (vs 2 A) and is rated 250 VAC (vs 125 VAC), but its mating gold thickness is 8.00 µinch (0.203 µm) — roughly one-quarter the plating of 2355186-8. For applications requiring high mating cycle counts or corrosive resistance, the thicker gold justifies the original part.
