For signal-level loads — logic, I/O, low-power distribution — the current ceiling is well within the housing's UL94 V-0 thermoplastic limit. ## Through-Hole Mount and Board Fit The solder posts measure 0.095\" (2.41 mm) long — enough for a standard 0.062\" PCB with good through-hole wetting. The base product number 77313 covers the family; this specific variant carries the -401-70LF suffix indicating the tin-plated, 70-position, through-hole configuration. No official pin-compatible replacement is listed — the BERGSTIK series is broad, but each position count and plating option is a distinct order code.","metaTitle":"77313-401-70LF Amphenol ICC BERGSTIK Header 70 Pos 2.54mm","metaDescription":"77313-401-70LF BERGSTIK header, 70 positions, 0.100\" pitch, tin-plated, active production.
