Is there a pin-compatible replacement for RC0402FR-075K1L?

No direct pin-for-pin replacement with identical parameters has been identified. RC0402FR-074K99L shares the same package and pinout but has a slightly different resistance (4.99kΩ vs 5.1kΩ) that requires engineering review.

What risks should I check before replacing RC0402FR-075K1L?

Key risks include package size mismatch, which requires a PCB layout change, and resistance value deviation. Always verify the substitute's power rating and temperature coefficient (TCR) meet or exceed the original's specifications.
