AI replacement insight

Electrical riskmedium

Power rating must be carefully checked (≥1.5W). Resistance and tolerance must match application needs.

Package risklow

2512 is a standard package, but land patterns should be confirmed.

Sourcing risklow

22Ω 2512 resistors are widely available from multiple vendors.

Can it be replaced directly?

No exact drop-in replacement has been verified. FOJAN FRP2512F22R0TS is a strong candidate with upgraded power and tolerance. Other options may have slight resistance differences.

Best replacement path

The best replacement path is finding a 2512 resistor with at least 1.5W power rating, 22Ω resistance, and ≤5% tolerance. FOJAN FRP2512F22R0TS is a strong upgrade.

Main risk

The main risk is using a replacement with an insufficient power rating, which could lead to overheating and failure. A 1.5W minimum rating is recommended.

Recommended alternatives

A 22Ω, 2512 resistor with a higher 2W power rating and tighter ±1% tolerance, offering an upgrade path.
