Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD2153C50 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 215 kOhms
• Tolerance: ±0.25%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Resistant feature

Allowable Variation Parameters:

• Power Rating: Equal or greater than 0.1W
• Product Status: Active or Obsolete
• Packaging format: May differ (bulk, tape & reel, etc.)
• Additional certifications: May be present (e.g., AEC-Q200)

The substitute part RN73R2ATTD2153C50 meets all mandatory matching parameters and exceeds the power rating requirement (0.125W vs. 0.1W), making it a valid electrical and mechanical equivalent.

Engineering Selection Recommendations

The RN73R2ATTD2153C50 is a direct electrical and mechanical substitute for the RN732ATTD2153C50. Selection of this substitute part is supported by the following factors:

Product Status Advantage: The RN73R2ATTD2153C50 is classified as Active, ensuring continued availability and manufacturing support, whereas the RN732ATTD2153C50 is Obsolete.

Compliance and Certification: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The substitute part includes AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components.

Electrical Performance: The substitute part maintains identical resistance value, tolerance, temperature coefficient, and operating temperature range. The increased power rating (0.125W vs. 0.1W) provides additional thermal margin without affecting circuit performance.

Physical Compatibility: Identical package dimensions, footprint, and termination count ensure direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD2153C50 be used as a direct replacement for RN732ATTD2153C50 in existing designs?

A: Yes. The RN73R2ATTD2153C50 meets all electrical and mechanical specifications of the RN732ATTD2153C50. Identical package dimensions, resistance value, tolerance, and temperature characteristics ensure functional equivalence. The increased power rating and AEC-Q200 certification of the substitute part do not create compatibility issues.

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

A: The RN73R2ATTD2153C50 is rated for 0.125W compared to the 0.1W rating of the RN732ATTD2153C50. This higher power rating provides additional thermal headroom and does not negatively impact circuit operation. The substitute part can safely handle the same or lower power dissipation as the original part.

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

A: No. AEC-Q200 certification indicates that the substitute part meets automotive reliability and quality standards. This certification is a superset of standard industrial requirements and does not restrict use in non-automotive applications. The part remains fully compatible with all applications suitable for the original RN732ATTD2153C50.

Q: Are there packaging format differences between these parts?

A: The RN732ATTD2153C50 is supplied in standard packaging, while the RN73R2ATTD2153C50 is supplied in Tape & Reel (TR) format. Both formats contain identical components. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or compatibility.

Q: What is the basis for confirming these parts are equivalent?

A: Equivalence is confirmed through matching of all critical electrical parameters (resistance, tolerance, temperature coefficient, operating temperature range), identical physical package specifications (0805 2012 Metric), and identical composition (thin film). Both parts are manufactured by KOA Speer Electronics, Inc. and maintain identical RoHS and moisture sensitivity compliance.
