Is there a pin-compatible replacement for RT0402BRD078K2L?

While many 0402 resistors are pin-compatible in package, no direct electrical replacement has been verified. Substitutes like AC0402FR-078K2L have a much wider tolerance (±1%) and are not suitable for precision applications.

What risks should I check before replacing RT0402BRD078K2L?

Verify that the substitute's resistance tolerance (target is ±0.1%), temperature coefficient (TCR, target is 25 ppm/°C), and resistance value are acceptable for your circuit's performance and stability requirements.

The Yageo RT0402BRD078K2L is a precision 0402 thin-film resistor with 8.2 kΩ resistance, tight ±0.1% tolerance, and a low 25 ppm/°C TCR. Finding a direct replacement requires matching these critical precision parameters.

AI replacement insight

Electrical riskhigh

Target is a precision part; most alternatives have relaxed tolerance/TCR or different resistance.

Package risklow

The 0402 package is standardized, ensuring form-factor compatibility.

Can it be replaced directly?

No direct, verified pin-to-pin replacements were found. Alternatives exist but require careful review of tolerance, TCR, or resistance value.

Best replacement path

Search for 0402 thin-film resistors with 8.2 kΩ resistance, ±0.1% tolerance, and a TCR of ≤25 ppm/°C.

Main risk

The primary risk is substituting a general-purpose resistor, which will degrade circuit precision due to wider tolerance and higher temperature drift.

Recommended alternatives

An automotive-grade 0402 8.2kΩ resistor with a wider tolerance (±1%) and higher TCR (±100 ppm/°C).
