ZX-SH1.0-7PWT
Megastar
Needs validationmedium risk
A strong functional alternative with matching pitch, pin count, orientation, and electrical ratings; requires footprint verification.
Best Alternatives to SM07B-SRSS-TB(LF)(SN)
Finding a substitute for the JST SM07B-SRSS-TB(LF)(SN) 7-pin header involves matching its 1.0mm pitch, side-entry SMT form, and electrical ratings. Several functional alternatives exist, but require careful mechanical verification.
AI replacement insight
Package riskmedium
Footprint and housing dimensions must be verified from datasheets.
Electrical risklow
Key electrical ratings (voltage, current) are matched by strong candidates.
Can it be replaced directly?
Direct replacement for SM07B-SRSS-TB(LF)(SN) should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Cross-vendor functional alternatives like ZX-SH1.0-7PWT and HC-1.0-7PWT offer similar performance but require mechanical verification.
Main risk
The primary risk is mechanical incompatibility. The housing dimensions, mounting tab locations, and solder pad layout of alternatives may differ from the JST original, even with the same pitch and pin count.
