Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD8980C25 serves as a direct functional substitute for the obsolete RN732ATTD8980C25. Both components share identical electrical specifications (898 Ohms, ±0.25% tolerance, ±25ppm/°C temperature coefficient) and physical dimensions (0805 package, 2.00mm x 1.25mm).

The substitute part provides the following advantages:

Product Status: The RN73R2ATTD8980C25 maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Power Rating Enhancement: The increased power rating of 0.125W (1/8W) versus 0.1W (1/10W) provides additional thermal margin without affecting circuit performance or physical footprint.

Automotive Qualification: The AEC-Q200 certification of the substitute part extends application scope to automotive and high-reliability environments while maintaining compatibility with general industrial applications.

Compliance: Both components maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility.

Selection of the RN73R2ATTD8980C25 is appropriate for all applications previously specified for the RN732ATTD8980C25, with the added benefit of active product availability and enhanced thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD8980C25 be used as a direct replacement for the RN732ATTD8980C25?

A: Yes. Both components share identical resistance (898 Ohms), tolerance (±0.25%), temperature coefficient (±25ppm/°C), operating temperature range (-55°C ~ 155°C), package format (0805), and physical dimensions. The substitute part is electrically and mechanically compatible.

Q: What is the difference in power rating between these parts?

A: The main part is rated at 0.1W (1/10W), while the substitute is rated at 0.125W (1/8W). The higher power rating of the substitute provides additional thermal dissipation capability without changing the physical size or electrical characteristics.

Q: Does the AEC-Q200 certification of the substitute part affect general industrial applications?

A: No. AEC-Q200 certification indicates automotive-grade reliability and is a superset qualification. Components meeting AEC-Q200 standards are suitable for all applications requiring the base specifications, including general industrial use.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both components are packaged in 0805 (2012 Metric) format with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.024" (0.60mm). PCB footprints are identical.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity limitations. Storage and handling do not require special moisture control measures, simplifying logistics and inventory management.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RN732ATTD8980C25 and RN73R2ATTD8980C25 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the main part classified as obsolete?

A: Obsolescence typically results from manufacturer discontinuation decisions based on market demand, product line consolidation, or transition to newer product series. The RN73R2ATTD8980C25 represents the active equivalent within the KOA Speer Electronics product portfolio.
