A 68Ω, 1W, 2512 resistor from the same manufacturer with a wider ±5% tolerance versus the target's ±1%.
Best Alternatives to 25121WF680JT4E
Finding a replacement for the UNI-ROYAL 25121WF680JT4E, a 68Ω ±1% 1W 2512 resistor, involves checking key parameters. Several parametric alternatives exist, but require careful review of tolerance or resistance values.
AI replacement insight
Electrical riskmedium
Tolerance mismatch from ±1% to ±5% is the primary concern for circuit accuracy.
Package risklow
All viable candidates match the 2512 package, ensuring physical compatibility.
Can it be replaced directly?
No direct, 1-to-1 replacement was found. All candidates require a trade-off, primarily on resistance tolerance.
Best replacement path
Parametric alternatives with relaxed tolerance or different resistance values.
Main risk
The main risk is substituting a ±1% precision resistor with a ±5% general-purpose one, which can impact circuit performance.

Questions & answers
There is no direct drop-in replacement among the candidates. `CRH2512J68R0E04Z` offers a higher power rating (2W) but has a weaker tolerance (±5%). Other parts match resistance but also have ±5% tolerance. The best choice depends on whether your circuit is more sensitive to tolerance or can benefit from a higher power rating.
