Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD2003C50 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 200 kOhms
• Tolerance: ±0.25%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistant feature

Allowable Variation:

• Power rating may be equal to or greater than the original 0.1W specification
• Product status may transition from obsolete to active
• Additional certifications (such as AEC-Q200) may be present in substitute parts

The RN73R2ATTD2003C50 qualifies as a direct substitute based on these criteria, with the distinction of higher power rating (0.125W) and active product status with automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD2003C50 serves as the direct substitute for the obsolete RN732ATTD2003C50. Selection of this substitute is supported by the following engineering factors:

Product Status Transition: The substitute part maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance Equivalence: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, preserving environmental and handling requirements.

Enhanced Qualification: The substitute incorporates AEC-Q200 automotive qualification, providing additional reliability assurance without compromising the original electrical specifications.

Power Rating Advantage: The increased power rating (0.125W versus 0.1W) provides design margin while maintaining identical physical dimensions and electrical characteristics.

Electrical Parameter Preservation: Resistance, tolerance, temperature coefficient, and operating temperature range remain identical, ensuring direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD2003C50 be used as a direct replacement for RN732ATTD2003C50?

A: Yes. Both parts share identical resistance (200 kOhms), tolerance (±0.25%), package (0805), composition (thin film), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute features higher power rating (0.125W) and active product status.

Q: What is the significance of the power rating difference between the two parts?

A: The RN73R2ATTD2003C50 power rating of 0.125W exceeds the original 0.1W specification. This provides additional thermal margin in circuit applications without altering electrical performance or physical dimensions.

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

A: No. AEC-Q200 is an automotive qualification standard that represents additional testing and reliability assurance. Its presence does not compromise compatibility with applications originally designed for the non-qualified main part.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both parts are packaged in 0805 (2012 Metric) format 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 packaging difference between these parts?

A: The main part RN732ATTD2003C50 packaging information is not specified in the provided data. The substitute RN73R2ATTD2003C50 is supplied in Tape & Reel (TR) format.

Q: Are both parts RoHS compliant?

A: Yes. Both RN732ATTD2003C50 and RN73R2ATTD2003C50 are ROHS3 compliant with identical moisture sensitivity level of 1 (Unlimited).
