FOJAN
A very similar resistor from the same manufacturer and series, with a 5% lower resistance value.
Finding a substitute for the FRC0603F1401TS 1.4kΩ resistor involves balancing trade-offs. While several 0603 resistors are available, they may differ in resistance value or power rating, requiring careful engineering review to ensure compatibility with your application.
Resistance or power rating mismatches require circuit analysis to ensure performance and reliability.
All reviewed candidates use the same 0603 package, ensuring physical compatibility.
No perfect 1-to-1 replacement was found. AR03BTCX1401 matches resistance but has a lower power rating. Other candidates match power but have slightly different resistance values.
If resistance is critical, AR03BTCX1401 is an option but requires power budget verification. If resistance can vary by ~5-7%, FRC0603F1331TS or the Yageo/Vishay parts are strong candidates.
The primary risk is a mismatch in either resistance value or power rating, both of which require engineering validation.

The 'best' alternative depends on your circuit's needs. If resistance must be exactly 1.4kΩ, AR03BTCX1401 is an option, but you must verify its lower 0.0625W power rating is acceptable. If your circuit tolerates a 5-7% resistance change, parts like FRC0603F1331TS or RT0603BRD071K3L are excellent choices with matching power ratings.
