Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD8872D50 is determined by strict equivalence in the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 88.7 kOhms
• Tolerance: ±0.5%
• 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: The substitute part may have equal or higher power dissipation rating (0.125W or greater is acceptable for 0.1W applications)
• Product Status: Active status substitutes are preferred over obsolete parts
• Packaging Format: Tape & Reel (TR) packaging is compatible with component placement equipment

The RN73R2ATTD8872D50 meets all mandatory matching parameters and provides enhanced specifications through higher power rating and active product status.

Engineering Selection Recommendations

The RN73R2ATTD8872D50 is the direct substitute for the obsolete RN732ATTD8872D50. Selection is based on the following engineering criteria:

Product Status Advantage: The substitute part carries Active product status, ensuring continued availability and manufacturing support, whereas the main part is classified as Obsolete.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH Unaffected status. The substitute part includes Automotive AEC-Q200 qualification, providing additional quality assurance for applications requiring automotive-grade reliability.

Electrical Equivalence: Resistance value, tolerance, temperature coefficient, and operating temperature range are identical. The substitute part's higher power rating (0.125W versus 0.1W) provides design margin without affecting circuit performance in applications designed for 0.1W dissipation.

Physical Compatibility: Identical 0805 (2012 Metric) package dimensions and termination configuration ensure direct board-level substitution without layout modifications.

Moisture Resistance: Both parts feature moisture-resistant thin film construction with MSL 1 rating, maintaining environmental protection specifications.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD8872D50 be used as a direct replacement for RN732ATTD8872D50?

A: Yes. The substitute part is electrically and mechanically equivalent. Identical resistance value (88.7 kOhms), tolerance (±0.5%), temperature coefficient (±50ppm/°C), and package (0805) ensure direct substitution. The higher power rating (0.125W) is compatible with applications designed for 0.1W dissipation.

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

A: The main part is rated at 0.1W (1/10W), while the substitute is rated at 0.125W (1/8W). The substitute's higher power rating provides additional thermal margin and does not negatively impact circuit operation in standard applications.

Q: Are the physical dimensions identical?

A: Yes. 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). No PCB layout modifications are required.

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

A: AEC-Q200 is an automotive industry qualification standard. The substitute part's AEC-Q200 rating indicates compliance with automotive reliability and quality requirements, providing additional assurance for applications requiring automotive-grade components.

Q: Are both parts RoHS compliant?

A: Yes. Both the main part and substitute are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the packaging difference?

A: The main part is supplied in standard packaging, while the substitute is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated component placement equipment and does not affect component performance or compatibility.

Q: Can the substitute part be used in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±50ppm/°C, ensuring stable performance across the full operating range.
