Is there a pin-compatible replacement for FRC0603F1403TS?

Yes, many manufacturers offer 140kΩ, 1%, 0.1W resistors in the standard 0603 package. These are generally pin-compatible, but always verify the datasheet for exact dimensions and pad layout.

What risks should I check before replacing FRC0603F1403TS?

Verify the replacement's resistance, tolerance, power rating, and temperature coefficient. Using a part with a different resistance will change circuit behavior. An underrated part may overheat and fail.

Finding a replacement for the FRC0603F1403TS, a 140kΩ 1% 0.1W 0603 resistor, requires checking key parameters. While direct drop-in replacements exist, functional alternatives with different resistance values may be considered if the circuit allows.

AI replacement insight

Electrical riskhigh

Using a part with incorrect resistance or power rating can cause circuit malfunction or damage.

Package risklow

0603 is a standard SMT package with high compatibility between vendors.

Sourcing riskmedium

140kΩ is a standard E96 value, but availability can vary by region and distributor.

Can it be replaced directly?

A direct replacement for FRC0603F1403TS should have 140kΩ resistance, ±1% tolerance, a 0.1W or higher power rating, and a 0603 package.

Best replacement path

Search for a 140kΩ, 1%, 0.1W (or higher), 0603 resistor. Consider AEC-Q200 or anti-sulfur parts for higher reliability.

Main risk

The main risk is using a resistor with the wrong resistance value, which can alter circuit behavior, or an insufficient power rating, leading to failure.

Recommended alternatives

Functional alternative in a 0603 package with different resistance (100kΩ) and added AEC-Q200 qualification.
