Excellent alternative from the same manufacturer with identical key specs and package.
HoYLR2512-3W-100mR-1% is a 3W, 100mΩ, 1% tolerance current sense resistor in a 2512 package. Finding a suitable replacement requires matching these key parameters, package size, and operating temperature range.
Some alternatives have lower max temp or different technology. Must verify.
All viable candidates are in the same 2512 package. Verify land pattern.
Direct replacement for HoYLR2512-3W-100mR-1% should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The strongest alternatives are HoLLR2512-3W-100mR-1% from the same manufacturer and RLP25FEGR100 from TAI-TECH, which match all key electrical parameters.
The primary risk is a mismatch in operating temperature range or subtle differences in resistor technology (Metal Alloy vs. Foil/Strip) which can affect performance under pulse conditions.
