Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD2001F10 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±10ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistant feature

Allowable Variation:

• Power rating may be equal to or greater than 0.1W, provided the physical dimensions remain compatible with the 0805 package footprint

The substitute part RN73R2ATTD2001F10 meets all mandatory matching parameters and provides an increased power rating of 0.125W (1/8W), which is compatible with the same package geometry and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD2001F10 is a direct functional substitute for the obsolete RN732ATTD2001F10. Both components share identical electrical specifications, package geometry, and environmental operating parameters. The substitute part offers the following advantages:

Active Product Status: The RN73R2ATTD2001F10 is currently in active production, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Enhanced Power Rating: The substitute provides 0.125W (1/8W) power rating versus the main part's 0.1W (1/10W). This higher rating is compatible with the same 0805 package footprint and does not introduce any physical or thermal incompatibilities.

Automotive Qualification: The substitute carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring equivalent environmental performance and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD2001F10 be used as a direct replacement for the RN732ATTD2001F10 in existing designs?

A: Yes. The substitute part maintains identical resistance, tolerance, package dimensions, temperature coefficient, and operating temperature range. The increased power rating of 0.125W versus 0.1W is compatible with the same 0805 package and does not create thermal or physical conflicts.

Q: Are there any differences in physical dimensions between these two parts?

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 of 0.024" (0.60mm).

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

A: AEC-Q200 is an automotive industry qualification standard. The substitute part meets this standard, indicating it has undergone additional reliability testing and qualification. This does not prevent use in non-automotive applications and provides enhanced assurance for any application requiring automotive-grade components.

Q: Will the substitute part require any circuit design modifications?

A: No. The electrical parameters—resistance value, tolerance, temperature coefficient, and operating temperature range—are identical. The higher power rating of the substitute is a conservative design margin and requires no circuit modifications.

Q: Are the packaging options different between the main part and substitute?

A: The main part is listed without specified packaging notation, while the substitute is supplied in Tape & Reel (TR) format. Both use the same 0805 package case. Verify packaging requirements for your procurement process.

Q: What is the moisture sensitivity level, and does it differ between these parts?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. There is no difference in moisture handling between the two parts.
