Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD3003F25 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 300 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Features: Moisture Resistant

Allowable Variation:

• Power Rating: The substitute part may have equal or higher power rating than the original 0.1W specification, provided all other parameters remain equivalent.

The RN73R2ATTD3003F25 meets all mandatory matching parameters and features a higher power rating of 0.125W (1/8W), making it a valid substitute for applications where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD3003F25 is the direct substitute for the obsolete RN732ATTD3003F25. Both components are manufactured by KOA Speer Electronics, Inc. and share identical electrical and mechanical specifications across all critical parameters.

The substitute part offers the following advantages:

• Active Product Status: The RN73R2ATTD3003F25 is currently in active production, ensuring long-term availability and supply chain continuity.
• Higher Power Rating: The 0.125W rating provides additional thermal margin compared to the original 0.1W specification.
• Automotive Qualification: The RN73R2ATTD3003F25 carries AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards.
• Regulatory Compliance: Both ROHS3 and REACH compliance are maintained.

The substitute part is suitable for direct replacement in all applications where the RN732ATTD3003F25 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD3003F25 be used as a direct replacement for the RN732ATTD3003F25?

A: Yes. The RN73R2ATTD3003F25 is a direct substitute. Both components have identical resistance (300 kOhms), tolerance (±1%), package (0805), composition (thin film), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 155°C). The substitute has a higher power rating (0.125W vs. 0.1W), which is acceptable for substitution purposes.

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

A: The RN732ATTD3003F25 is rated at 0.1W (1/10W), while the RN73R2ATTD3003F25 is rated at 0.125W (1/8W). The higher power rating of the substitute part does not affect compatibility and provides additional thermal headroom in the application.

Q: Are both parts in the same physical package?

A: Yes. Both the RN732ATTD3003F25 and RN73R2ATTD3003F25 use the 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.024" (0.60mm). They are footprint-compatible.

Q: Why is the original part obsolete?

A: The RN732ATTD3003F25 is classified as obsolete by the manufacturer. The RN73R2ATTD3003F25 represents the current active product line from KOA Speer Electronics, Inc. for this resistance value and package combination.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. The substitute part includes additional AEC-Q200 automotive qualification, which indicates enhanced reliability testing and quality assurance. This additional qualification does not restrict use in non-automotive applications.

Q: What is the moisture sensitivity level for both parts?

A: Both components have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.
