Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD7233F100 is based on strict equivalence of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 723 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Resistant construction

Allowable Variation:

• Power rating may be equal to or greater than 0.1W, provided the physical dimensions remain compatible with the 0805 package footprint

The RN73R2ATTD7233F100 qualifies as a direct substitute based on these criteria. It maintains identical resistance, tolerance, package, composition, temperature characteristics, and moisture resistance while providing an increased power rating of 0.125W (1/8W). The substitute part is manufactured by the same supplier and is classified as active product status.
