Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN731ETTP2002C25 is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 kOhms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture resistance feature
• RoHS3 compliance

The substitute part RN73R1ETTP2002C25 meets all these electrical and mechanical parameters. The primary distinction is that the substitute part carries automotive AEC-Q200 qualification, which represents an additional certification level rather than a deviation from the base specifications.

Parameter Comparison

Engineering Selection Recommendations
