Yageo
A strong pin-compatible candidate from Yageo with identical resistance, power, and package.
FRC1206F4021TS is a general-purpose 4.02kΩ, 1%, 0.25W thick film resistor in a standard 1206 package. This page reviews and compares potential alternatives.
Key electrical parameters are identical for the top candidate.
Package is identical (1206), ensuring form and fit.
Candidates are from major manufacturers like Yageo.
Direct replacement for FRC1206F4021TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
RC1206FR-074K02L from Yageo is a strong pin-to-pin candidate with identical key parameters.
The primary risk is ensuring the application can tolerate minor variations between manufacturers, although key specs match.
