What risks should I check before replacing PA0805FRE470R02L?

Key risks include mismatched Temperature Coefficient (TCR) affecting measurement accuracy, and lack of AEC-Q200 qualification for automotive designs. Always verify datasheet parameters.

PA0805FRE470R02L Alternatives, Datasheet & Cross Reference | Yageo

Finding a substitute for the Yageo PA0805FRE470R02L, a 20mΩ 1% 0.4W AEC-Q200 current sense resistor, requires matching precision, power, and automotive qualification. Several alternatives exist with minor trade-offs.

AI replacement insight

Electrical riskmedium

TCR mismatch can impact circuit accuracy in some applications.

Package risklow

All viable candidates are in the same 0805 package.

Sourcing risklow

Multiple vendors produce similar parts for this category.

Can it be replaced directly?

Direct replacement for PA0805FRE470R02L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

For automotive use, PE0805FRE470R02Z is the closest path, requiring TCR validation. For non-automotive, RLM10FTSMR020 is a strong parametric match.

Main risk

The primary risk is a mismatch in precision (TCR) or a lack of required automotive-grade qualification (AEC-Q200).

Recommended alternatives

Yageo PE0805FRE470R02Z is a pin-compatible alternate with higher power rating but potentially wider TCR. Review required.
