Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD3012C10 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 30.1 kOhms
• Tolerance: ±0.25%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±10ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistant feature
• RoHS3 Compliance

Allowable Variation:

• Power rating may increase from 0.1W to higher ratings (0.125W or greater) without affecting functional compatibility, as higher power-rated components operate within the same thermal and electrical envelope for this package type.

The substitute part RN73R2ATTD3012C10 meets all mandatory matching parameters and represents a direct functional equivalent with enhanced power rating capability.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD3012C10 be used as a direct replacement for RN732ATTD3012C10 in existing designs?

A: Yes. The RN73R2ATTD3012C10 is electrically and mechanically equivalent. Identical resistance value, tolerance, temperature coefficient, operating temperature range, and 0805 package dimensions ensure direct PCB compatibility without design modification.

Q: What is the significance of the power rating difference (0.1W vs. 0.125W)?

A: The higher power rating in the substitute part indicates greater thermal dissipation capability. For applications operating at or below 0.1W, this difference is not functionally significant. The substitute part operates within the same thermal envelope for the 0805 package format.

Q: Does the AEC-Q200 qualification on the substitute part affect compatibility?

A: No. AEC-Q200 qualification represents additional reliability testing and documentation. It does not alter electrical or mechanical performance. The substitute part remains fully compatible with non-automotive applications.

Q: Are the packaging formats interchangeable?

A: The main part is specified as loose component packaging, while the substitute is supplied in Tape & Reel (TR) format. Both contain identical components. Tape & Reel format is standard for automated assembly processes and does not affect component performance.

Q: What compliance certifications apply to both parts?

A: Both RN732ATTD3012C10 and RN73R2ATTD3012C10 are ROHS3 compliant and REACH Unaffected. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Is the substitute part available in inventory?

A: The RN73R2ATTD3012C10 is listed as Active product status with 973 Pcs New Original In Stock, ensuring supply availability for production requirements.
