Yageo
A form-fit-function compatible resistor with tighter tolerance (±1%) and better temperature stability.
Find pin-compatible and upgraded replacements for the UNI-ROYAL 25121WJ0152T4E, a 1.5kΩ 1W 5% thick film resistor. Alternatives from Yageo and FOJAN offer similar or improved performance for your design.
Core parameters are matched or improved, but check overload voltage on some candidates.
All recommended substitutes use the same 2512 package, ensuring form-fit compatibility.
Direct replacement for 25121WJ0152T4E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Upgrade to a 1% tolerance part like Yageo RC2512FK-071K5L for better precision in the same form factor.
The primary risk is ensuring the replacement's voltage ratings, particularly maximum overload voltage, are sufficient for the application.
