RESI
Needs validationlow risk
A 3W, 1mΩ, 1% resistor in a 2512 package with a matching TCR of ±100ppm/℃.
Best Alternatives to HoLLR2512-3W-1mR-1%
Finding a replacement for the HoLLR2512-3W-1mR-1% involves matching its 3W power, 1mΩ resistance, and 2512 package. Several pin-compatible options exist, but TCR and land pattern verification are key.
AI replacement insight
Electrical risklow
Low for matched 3W parts; high for any part with a lower power rating.
Package risklow
2512 is a standard package, but land pattern verification is always recommended.
Sourcing riskmedium
Multiple vendors offer similar parts, but stock levels should be checked.
Can it be replaced directly?
Yes, parts like TAI-TECH RLP25FEGR001 and RESI ECSR2512FR001K9 are strong candidates for pin-to-pin replacement after datasheet review.
Best replacement path
Start with Datasheet verified or Strong match candidates for HoLLR2512-3W-1mR-1%, then review parametric alternatives for package and electrical fit.
Main risk
The main risk is using a substitute with a lower power rating, which can lead to overheating and failure.
