AI replacement insight
Package risklow
Multiple candidates match the 2512 package.
Electrical riskmedium
Power rating and TCR must be carefully checked. Some candidates have no power margin or weaker TCR.
Can it be replaced directly?
Yes, RLP25FEGR010 is a potential pin-to-pin replacement with superior power and TCR ratings. PA2512FKE7W0R01E is a parametric match but lacks a power safety margin.
Best replacement path
RLP25FEGR010 from TAI-TECH is a strong upgrade path, offering higher power (3W) and better TCR (±50ppm/°C) in the same 2512 package.
Main risk
The main risk is using a substitute with an insufficient power rating or a different TCR, which can affect measurement accuracy and reliability.
