UNI-ROYAL
A 2512 resistor with different resistance (5.1Ω) and wider tolerance (±5%). Requires review.
FRC2512F5R60TS is a 1W, 5.6Ω, ±1% tolerance thick film resistor in a 2512 package. Finding a direct replacement requires matching these key parameters, especially power rating and tolerance.
Tolerance, resistance, and power margin mismatch.
Package is a standard 2512.
No direct, verified drop-in replacement is currently available. All potential candidates require engineering review due to parametric differences.
Parametric alternatives with different resistance and tolerance.
The primary risks are the wider tolerance (±5% vs. target's ±1%) and lack of power rating safety margin in available alternatives.
