Matches resistance and package but lacks the target's AEC-Q200 automotive qualification.
AC0805FR-07100KL is a popular AEC-Q200 qualified 100kΩ thick film resistor from Yageo in an 0805 package. Finding a substitute requires matching its automotive grade, resistance, and power rating.
Using a non-AEC part in an automotive design compromises reliability and safety.
0805 is a standard package with excellent availability.
No direct drop-in replacement has been verified. The closest candidate, FRH0805B1003TS, matches key parameters but is not automotive grade.
Prioritize AEC-Q200 qualified 0805 resistors with 100kΩ resistance and ±1% or better tolerance.
The primary risk is substituting a commercial-grade resistor for an automotive-qualified (AEC-Q200) component.

| Feature / factor | AC0805FR-07100KL | FRH0805B1003TS | RC0805FR-0791KL | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 | 0805 | 0805 | 0805 — Form factor matches.; RC0805FR-0791KL: Form factor matches. | |
| Resistance | 100kΩ | 100kΩ | 91kΩ | 100kΩ / 91kΩ — Resistance value matches.; RC0805FR-0791KL: Resistance is 9% lower. | |
| Tolerance | ±1% | ±0.1% | - | ±0.1% — Candidate has tighter tolerance. | |
| Power | 1/8W | 1/8W | 1/8W | 1/8W — Power rating matches.; RC0805FR-0791KL: Power rating matches. | |
| Qualification | AEC-Q200 | None | None | None — Candidate is not automotive grade.; RC0805FR-0791KL: Candidate is not automotive grade. |
The best alternative is another AEC-Q200 qualified 100kΩ, 1/8W, 0805 resistor. Non-automotive parts like FRH0805B1003TS match electrically but lack the qualification and require engineering review.
