Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD7412B05 is a direct substitute for the RN732ATTD7412B05 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical resistance (74.1 kOhms), tolerance (±0.1%), temperature coefficient (±5ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute part features a higher power rating (0.125W versus 0.1W), which provides additional thermal margin without affecting circuit performance.

Physical Compatibility: Both components utilize the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W) and maximum seated height (0.024"), ensuring direct PCB footprint compatibility.

Compliance and Certification: The RN73R2ATTD7412B05 maintains ROHS3 compliance and REACH Unaffected status identical to the main part. The addition of AEC-Q200 automotive qualification in the substitute part represents an enhancement without introducing incompatibility.

Supply Continuity: The RN73R2ATTD7412B05 carries Active product status, ensuring ongoing availability and supply chain support compared to the Obsolete status of the main part.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD7412B05 be used as a direct replacement for the RN732ATTD7412B05?

A: Yes. Both parts share identical electrical specifications (74.1 kOhms ±0.1%, ±5ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and physical package dimensions (0805, 2.00mm x 1.25mm). The substitute part features a higher power rating (0.125W versus 0.1W), which is compatible with applications designed for the original part.

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

A: The RN732ATTD7412B05 is rated at 0.1W (1/10W), while the RN73R2ATTD7412B05 is rated at 0.125W (1/8W). The higher power rating of the substitute part does not affect circuit operation and provides additional thermal dissipation capability.

Q: Are the physical dimensions identical?

A: Yes. Both parts 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 the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive qualification standard. The RN73R2ATTD7412B05 meets this additional certification, which does not restrict its use in non-automotive applications. This represents an enhancement of the substitute part's qualification profile.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RN732ATTD7412B05 and RN73R2ATTD7412B05 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the main part listed as Obsolete?

A: The RN732ATTD7412B05 carries Obsolete product status, indicating that KOA Speer Electronics, Inc. has discontinued active production and support. The RN73R2ATTD7412B05 with Active status provides ongoing supply chain availability for this specification.
