Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD2002F10 is determined by the following critical parameters:

• Resistance Value: Must be 20 kOhms
• Tolerance: Must be ±1%
• Package / Case: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±10ppm/°C
• Operating Temperature Range: Must support -55°C ~ 155°C
• Moisture Resistance: Must be present

The RN73R2ATTD2002F10 qualifies as a direct substitute. While it features a higher power rating (0.125W vs. 0.1W), this represents an uprated capability that maintains full compatibility with the original specification. The increased power rating does not compromise performance in applications designed for the lower-rated component and provides additional thermal margin.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD2002F10 is the appropriate substitute for the obsolete RN732ATTD2002F10. Both components are manufactured by KOA Speer Electronics and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The RN73R2ATTD2002F10 carries AEC-Q200 automotive qualification, which represents an enhanced reliability standard. This certification does not restrict use in non-automotive applications and provides additional assurance of component quality and consistency. The higher power rating (0.125W vs. 0.1W) is a beneficial characteristic that does not introduce any compatibility concerns for circuits designed around the original 0.1W specification.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD2002F10 be used as a direct replacement for the RN732ATTD2002F10?

A: Yes. The substitute part maintains identical resistance value (20 kOhms), tolerance (±1%), package (0805), composition (thin film), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). The increased power rating represents an uprated capability that is fully compatible with the original specification.

Q: What is the significance of the higher power rating on the substitute part?

A: The RN73R2ATTD2002F10 is rated for 0.125W compared to the original 0.1W rating. This higher rating provides additional thermal margin and does not affect electrical performance in applications designed for the lower-rated component. The physical dimensions and thermal characteristics remain equivalent.

Q: Are there any packaging differences between these parts?

A: Both parts use the 0805 (2012 Metric) package with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and maximum seated height (0.024" / 0.60mm). They are mechanically interchangeable on PCB layouts.

Q: Does the AEC-Q200 certification on the substitute part affect its use in non-automotive applications?

A: No. AEC-Q200 is an automotive reliability standard that establishes enhanced quality and testing requirements. Parts meeting this standard are suitable for all applications, including non-automotive designs, and do not impose any restrictions on use.

Q: Are both parts RoHS compliant?

A: Yes. Both the RN732ATTD2002F10 and RN73R2ATTD2002F10 are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), meeting standard environmental and manufacturing requirements.
