Is there a pin-compatible replacement for RT0402BRD073K2L?

Several 0402 package parts are available, but they are general-purpose thick film resistors with much lower precision (±1% or ±5% tolerance) and higher TCR, making them unsuitable for precision applications.

What risks should I check before replacing RT0402BRD073K2L?

Key risks include changes in circuit accuracy due to wider resistance tolerance, temperature instability from higher TCR, and different noise characteristics if switching from Thin to Thick Film technology. Also, verify package size.

AI replacement insight

Electrical riskhigh

Switching to thick film parts introduces significant error.

Package riskhigh

One candidate has a non-matching 0805 package.

Can it be replaced directly?

No direct, datasheet-verified drop-in replacement is available in this list. All candidates have significant parametric or physical differences.

Best replacement path

Search for a 3.2kΩ, ±0.1% tolerance, ≤25ppm/°C TCR, thin film resistor in an 0402 package from other manufacturers.

Main risk

Degradation of circuit precision and thermal stability due to tolerance, TCR, and technology mismatches.

Recommended alternatives

A 3.4kΩ 1% thick film resistor in the same 0402 package; requires review due to lower precision.
