Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD7233F50 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 723 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Resistant construction

Allowable Variation Parameters:

• Power Rating: Equal or greater than 0.1W
• Product Status: Active or Obsolete
• Packaging Format: May differ (bulk, tape & reel, etc.)
• Certifications and Features: May include additional qualifications (e.g., AEC-Q200)

The RN73R2ATTD7233F50 qualifies as a direct substitute because it maintains all mandatory matching parameters while offering an increased power rating of 0.125W (1/8W) and includes automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD7233F50 is a qualified substitute for the obsolete RN732ATTD7233F50 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical resistance value (723 kOhms), tolerance (±1%), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 155°C). The substitute's increased power rating of 0.125W (1/8W) compared to the original 0.1W (1/10W) provides enhanced thermal margin without affecting circuit performance.

Mechanical Compatibility: Both components utilize 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). PCB layout and assembly processes require no modification.

Regulatory and Compliance Status: Both parts are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). The substitute includes AEC-Q200 automotive qualification, which represents an additional quality assurance level.

Supply Chain Advantage: The RN73R2ATTD7233F50 carries Active product status with 1155 pieces in stock, compared to the Obsolete status of the original part with 801 pieces available. Selection of the substitute ensures long-term availability and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD7233F50 be used as a direct replacement for the RN732ATTD7233F50 in existing designs?

A: Yes. Both parts share identical electrical specifications (723 kOhms ±1%, ±50ppm/°C, -55°C to 155°C operating range) and mechanical dimensions (0805 package, 2.00mm x 1.25mm). The substitute's higher power rating (0.125W vs. 0.1W) is compatible with all applications designed for the original part.

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

A: The RN73R2ATTD7233F50 is rated at 0.125W (1/8W) compared to the original 0.1W (1/10W). This 25% increase in power dissipation capability provides additional thermal headroom and does not negatively impact circuit operation. The substitute can safely handle the same current and voltage conditions as the original part.

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

A: No. AEC-Q200 is an automotive qualification standard that indicates enhanced reliability testing and quality assurance. This certification is additive and does not alter the electrical or mechanical characteristics of the component. The substitute remains fully compatible with non-automotive applications.

Q: Are there any packaging format differences between these parts?

A: The original RN732ATTD7233F50 is supplied in standard packaging format. The substitute RN73R2ATTD7233F50 is supplied in Tape & Reel (TR) format. Both formats contain identical components; the difference is in the delivery and handling method. Tape & Reel format is standard for automated assembly processes.

Q: What is the difference between the RN73 and RN73R series designations?

A: The RN73R series represents an enhanced product line within KOA Speer Electronics' thin film resistor portfolio. The RN73R2ATTD7233F50 belongs to the RN73R series and includes automotive AEC-Q200 qualification. Both series maintain identical electrical and mechanical specifications for the 723 kOhms ±1% 0805 package configuration.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RN732ATTD7233F50 and RN73R2ATTD7233F50 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
