What risks should I check before replacing AC0402FR-07620RL?

Key risks include: 1) Qualification: The target is AEC-Q200 qualified; many alternatives are not. 2) Resistance: Ensure the circuit tolerates any deviation from the original 620Ω value. 3) TCR and Power: Verify the temperature coefficient and power rating are suitable for your operating conditions.

AC0402FR-07620RL Alternatives, Datasheet & Cross Reference | Yageo

Yageo's AC0402FR-07620RL is a 620Ω, 1% tolerance, AEC-Q200 qualified thick film resistor in a 0402 package. Finding a direct, qualified replacement requires matching these key automotive-grade specifications.

AI replacement insight

Electrical riskmedium

Some alternatives have different resistance values that require circuit validation.

Package risklow

All viable candidates share the same 0402 package.

Sourcing riskhigh

Finding a substitute that matches both electrical parameters and AEC-Q200 qualification is challenging.

Can it be replaced directly?

Direct replacement for AC0402FR-07620RL should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

For non-automotive use, RC-02K6200FT is a strong match. For automotive use, an AEC-Q200 part with close resistance, like AC0402FR-07680RL, is the safest path, requiring circuit validation.

Main risk

The primary risk is substituting a non-AEC-Q200 qualified part into an automotive or high-reliability application.

Recommended alternatives

Matches all key electrical specs and package but is not automotive qualified.
