Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD1092D50 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 10.9 kOhms
• Tolerance: ±0.5%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistant construction

Allowable Variation:

• Power rating may be equal to or greater than the original specification (0.1W minimum)
• Packaging format may differ (bulk to Tape & Reel conversion acceptable)
• Product status may transition from Obsolete to Active
• Additional certifications (such as AEC-Q200) do not disqualify substitution

The substitute part RN73R2ATTD1092D50 meets all mandatory matching parameters while offering increased power rating (0.125W vs. 0.1W) and active product status with automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD1092D50 is a direct functional substitute for the RN732ATTD1092D50 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical resistance (10.9 kOhms), tolerance (±0.5%), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute's increased power rating (0.125W vs. 0.1W) provides enhanced thermal margin without altering circuit performance.

Physical Compatibility: Identical 0805 (2012 Metric) package dimensions and termination configuration ensure direct PCB footprint compatibility with no layout modifications required.

Regulatory Compliance: Both parts are ROHS3 Compliant and REACH Unaffected. The substitute carries AEC-Q200 automotive qualification, which represents an enhancement in reliability screening and does not introduce incompatibility.

Supply Chain Status: The transition from Obsolete (RN732ATTD1092D50) to Active (RN73R2ATTD1092D50) status ensures long-term availability and production support for ongoing applications.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and does not affect component performance or functionality.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD1092D50 be used as a direct replacement for RN732ATTD1092D50 in existing designs?

A: Yes. Both parts share identical electrical specifications (10.9 kOhms ±0.5%, ±50ppm/°C, -55°C ~ 155°C operating range) and physical dimensions (0805 package). The substitute's higher power rating (0.125W vs. 0.1W) is compatible with all applications designed for the original part.

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

A: The RN732ATTD1092D50 is rated at 0.1W (1/10W), while the RN73R2ATTD1092D50 is rated at 0.125W (1/8W). The substitute's increased power dissipation capability does not affect circuit operation and provides additional thermal headroom in power-limited applications.

Q: Are there any package or footprint differences?

A: No. Both parts use the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.024" / 0.60mm). PCB layouts require no modification.

Q: Why is the original part marked as Obsolete?

A: The RN732ATTD1092D50 carries Obsolete status, indicating discontinued production. The RN73R2ATTD1092D50 is an Active product from the same manufacturer with equivalent specifications, ensuring continued availability and supply chain support.

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

A: No. AEC-Q200 is an automotive qualification standard that represents enhanced reliability screening. Its presence on the substitute part does not introduce incompatibility and may provide additional assurance for applications requiring automotive-grade components.

Q: What is the difference in packaging format?

A: The original part is supplied in standard packaging, while the substitute is supplied in Tape & Reel (TR) format. This is a standard packaging configuration for automated assembly and does not affect component electrical or mechanical properties.

Q: Are both parts RoHS3 Compliant?

A: Yes. Both the RN732ATTD1092D50 and RN73R2ATTD1092D50 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
