A precision thin-film alternative from the same series but with a ~4.7% lower resistance value.
Best Alternatives to RT0402BRD0778K7L
Yageo's RT0402BRD0778K7L is a high-precision 78.7kΩ thin-film resistor in an 0402 package, featuring a tight ±0.1% tolerance and a low 25 ppm/°C TCR. Finding a suitable replacement requires matching these critical electrical parameters to ensure circuit accuracy and stability.
AI replacement insight
Electrical riskhigh
Using a thick film part in a precision application can cause failure.
Electrical riskmedium
Using a part with different resistance requires circuit re-evaluation.
Package risklow
All candidates share the same 0402 package.
Can it be replaced directly?
No direct, verified drop-in replacement is identified in this list. All candidates have parametric differences, either in precision (tolerance, TCR) or resistance value.
Best replacement path
Find another thin-film, 0402, 1/16W, 0.1% tolerance, 25ppm TCR resistor with the exact 78.7kΩ value.
Main risk
The primary risk is using a part with wider tolerance or higher TCR (e.g., 1% thick film), which will degrade the precision of the circuit.

Questions & answers
The best alternative depends on your circuit's tolerance. For high precision, parts from the same Yageo RT series with nearby resistance values (like RT0402BRD0782KL) are options if the value change is acceptable. For non-critical applications, a thick film resistor like RC0402FR-0778K7L matches the resistance value at a lower precision.
