Is there a pin-compatible replacement for RT0402BRD071K15L?

Yes, many 0402 package resistors are pin-compatible. However, a true drop-in replacement must also match the 1.15kΩ resistance, ±0.1% tolerance, and 25 ppm/°C TCR. No exact electrical match was found, but several parametric alternatives exist.

What risks should I check before replacing RT0402BRD071K15L?

Key risks include changes in resistance value, tolerance (from ±0.1%), and temperature coefficient (TCR, from 25 ppm/°C). Using a thick film resistor instead of thin film will impact stability and precision. Always verify the impact on your circuit's performance.

RT0402BRD071K15L Alternatives, Datasheet & Cross Reference | Yageo

The Yageo RT0402BRD071K15L is a precision thin-film chip resistor with 1.15 kΩ resistance, ±0.1% tolerance, and a 25 ppm/°C TCR in a 0402 package. Finding a direct replacement requires matching these tight specifications.

AI replacement insight

Electrical riskhigh

Target is a precision component; any deviation in resistance, tolerance, or TCR can affect circuit function.

Package risklow

0402 is a standard SMD package with many mechanically compatible options.

Can it be replaced directly?

No direct, one-to-one replacement with identical key parameters was found. All alternatives require engineering review for parametric differences.

Best replacement path

If the circuit tolerates a ~4% resistance change, Yageo's RT or AT series parts are best. Otherwise, a new search for an exact 1.15kΩ, 0.1%, 25ppm TCR part is needed.

Main risk

The primary risk is performance degradation from using a part with a different resistance value, a wider tolerance, or a higher TCR.

Recommended alternatives

An automotive-grade precision resistor with a slightly higher resistance. Matches tolerance and TCR.

Questions & answers

The best alternative depends on circuit tolerance. For precision, Yageo's RT0402BRD071K1L (1.1kΩ) or AT0402BRD071K2L (1.2kΩ) are close, but require verifying the resistance change. For non-critical applications, general-purpose 1.15kΩ resistors exist but have lower precision.
