Is there a pin-compatible replacement for RT0402BRD074K3L?

While several candidates share the 0402 package and are physically compatible, none are electrically pin-to-pin replacements due to significant differences in tolerance or TCR.

What risks should I check before replacing RT0402BRD074K3L?

Before replacing, verify the required resistance tolerance and temperature stability (TCR). Using a thick film or higher tolerance/TCR part like AC0402FR-074K3L in a precision circuit can cause performance failure.

AI replacement insight

Electrical riskhigh

Substituting a precision part with a general-purpose one can cause circuit failure.

Package risklow

All candidates share the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No, there are no direct, verified drop-in replacements for RT0402BRD074K3L in this list. All candidates have significant parametric differences.

Best replacement path

The best path is to find another thin film resistor with 4.3kΩ, ±0.1% tolerance, and ≤25ppm/°C TCR in an 0402 package. No direct match was found in this list.

Main risk

The main risk is substituting a precision resistor with a general-purpose one, leading to degraded circuit performance, instability over temperature, and higher noise.

Recommended alternatives

Matches resistance and package but is a thick film part with much looser tolerance (1%) and TCR (100ppm/°C).
