Is there a pin-compatible replacement for AC0402FR-07680RL?

Yes, many 0402 resistors are pin-compatible. For example, RT0402BRD07680RL shares the same package and resistance. However, it is not a drop-in replacement due to different technology and lack of automotive qualification.

What risks should I check before replacing AC0402FR-07680RL?

Key risks are: 1) Missing AEC-Q200 qualification if used in automotive systems. 2) Different technology (Thick vs. Thin Film) affecting performance. 3) Wider resistance tolerance, which can impact circuit accuracy.

AI replacement insight

Electrical riskhigh

Candidates may have different technology or wider tolerance.

Package risklow

The 0402 package is standardized, ensuring physical compatibility.

Sourcing riskhigh

Finding a substitute that also meets AEC-Q200 is critical and may be difficult.

Can it be replaced directly?

No direct drop-in replacement has been identified that matches all key parameters including AEC-Q200 qualification. All candidates require engineering review.

Best replacement path

For non-automotive applications, RT0402BRD07680RL is a potential upgrade in precision. For automotive use, a direct cross from another AEC-Q200 series is required.

Main risk

The primary risk is substituting a non-AEC-Q200 qualified part in an automotive application, which could compromise reliability and safety.

Recommended alternatives

A high-precision alternative with the same resistance and package, but different technology and not automotive-grade.
