Substitute Part Grouping Explanation

Substitution of the RN732ATTD1060C50 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 106 Ohms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Package Type: 0805 (2012 Metric) (physical and electrical compatibility)
• Composition: Thin Film (performance characteristics)
• Temperature Coefficient: ±50ppm/°C (stability specification)
• Operating Temperature Range: -55°C to 155°C (environmental limits)
• Moisture Resistance: Required feature
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The RN73R2ATTD1060C50 qualifies as a direct substitute based on matching all critical parameters. The higher power rating (0.125W vs. 0.1W) represents an upgrade that maintains backward compatibility while providing additional thermal margin. The active product status and automotive AEC-Q200 qualification of the substitute part enhance long-term availability and reliability assurance.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD1060C50 is the appropriate substitute for the obsolete RN732ATTD1060C50. Both parts maintain identical electrical specifications (106 Ohms, ±0.25% tolerance, ±50ppm/°C temperature coefficient) and physical form factor (0805 package). The substitute part offers enhanced product lifecycle status (active vs. obsolete) and automotive-grade qualification (AEC-Q200), ensuring sustained availability and reliability assurance for production environments.

The increased power rating of the substitute (0.125W vs. 0.1W) provides additional thermal headroom without introducing compatibility concerns, as the component remains within the same package envelope and electrical performance class. Both parts satisfy ROHS3 compliance and unlimited moisture sensitivity level requirements.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD1060C50 be used as a direct replacement for the RN732ATTD1060C50?

A: Yes. Both parts share identical resistance value (106 Ohms), tolerance (±0.25%), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 155°C), and 0805 package configuration. The substitute part's higher power rating (0.125W vs. 0.1W) is compatible with applications designed for the original part.

Q: What is the significance of the higher power rating in the substitute part?

A: The RN73R2ATTD1060C50 is rated for 0.125W compared to the original 0.1W rating. This represents a 25% increase in power dissipation capability, providing additional thermal margin in the same physical package. This upgrade does not affect electrical performance or circuit compatibility.

Q: Are there packaging differences between these parts?

A: No. Both parts use identical 0805 (2012 Metric) packaging with matching dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and height specifications (0.024" maximum seated height, 0.60mm). PCB footprints and assembly processes remain unchanged.

Q: What is the advantage of the AEC-Q200 qualification on the substitute part?

A: AEC-Q200 certification indicates the substitute part meets automotive industry reliability and quality standards. This qualification provides additional assurance for applications requiring automotive-grade components or enhanced reliability documentation, though both parts maintain equivalent electrical performance.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RN732ATTD1060C50 and RN73R2ATTD1060C50 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is identical (MSL 1, Unlimited) for both parts.
