SHOU HAN
A 12-pin, 1.0mm pitch header with a higher voltage rating (125V). Requires mechanical verification.
HC-1.0-12PWT is a 12-pin, 1.0mm pitch right-angle SMT header used for board-to-wire connections. This page provides analysis of potential alternatives, focusing on electrical and mechanical compatibility.
PCB footprint and connector height must be verified from datasheets to ensure mechanical fit.
Multiple candidates match the key voltage and current ratings.
Direct replacement for HC-1.0-12PWT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The JST part SM12B-SRSS-TB(LF)(SN) is from a major brand and likely represents the standard footprint for this connector type. Verifying your layout against the JST datasheet is the most reliable path.
The primary risk is mechanical incompatibility. While pitch and pin count may match, slight differences in the housing or solder pad layout can prevent a successful replacement.
