What risks should I check before replacing AT0402BRD071K6L?

Key risks include deviations in resistance value, tolerance, and Temperature Coefficient (TCR). The target is a precision thin-film resistor; using a lower-grade thick-film part can impact circuit accuracy and stability.

AT0402BRD071K6L Alternatives, Datasheet & Cross Reference | Yageo

Finding a substitute for the Yageo AT0402BRD071K6L precision resistor requires matching its 1.6kΩ resistance, ±0.1% tolerance, and ±25ppm/°C TCR. This guide reviews top alternatives and their trade-offs.

AI replacement insight

Electrical riskmedium

Precision parameters (tolerance, TCR) are critical and hard to match.

Package risklow

The 0402 package is a common industry standard.

Can it be replaced directly?

Direct replacement for AT0402BRD071K6L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use Panasonic ERA2AEB162X if power margins are sufficient; otherwise, a new part search focusing on higher power rating is needed.

Main risk

The primary risk is substituting with a part that has looser tolerance or a higher TCR, which would compromise the precision of the original design.

Recommended alternatives

A strong, pin-compatible alternative with identical key parameters; power rating requires engineering review.
