Excellent match with identical package, resistance, tolerance, power, and TCR. AEC-Q200 qualified.
Find the best substitutes for the FH RC-12K1001FT, a 1kΩ 1% 1W 2512 chip resistor. We've analyzed pin-compatible options and parametric alternatives to help you manage your supply chain.
All candidates use the same 2512 package, ensuring physical compatibility.
Many alternatives have 5% tolerance vs the target's 1%. This is a critical difference for precision applications.
1kΩ 2512 resistors are a common component type with many manufacturers and options available.
Yes, AC2512FK-071KL is a direct pin-compatible replacement for RC-12K1001FT, matching its package, resistance, tolerance, power rating, and TCR.
AC2512FK-071KL from Yageo is an excellent pin-to-pin replacement with identical key specs and the added benefit of AEC-Q200 qualification.
The primary risk is substituting with a part that has a looser tolerance (e.g., 5% instead of 1%) or a higher TCR, which could compromise circuit performance.
