Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD1111F10 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 1.11 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±10ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Resistant construction

Allowable Variation:

• Power rating may be equal to or greater than 0.1W, provided the physical dimensions remain compatible with the 0805 package specification

The substitute part RN73R2ATTD1111F10 meets all critical matching parameters. The increased power rating (0.125W vs. 0.1W) represents an upward-compatible specification that does not compromise circuit performance or physical fit.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD1111F10 is the direct substitute for the obsolete RN732ATTD1111F10. Selection is based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical resistance (1.11 kOhms), tolerance (±1%), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C to 155°C). The increased power rating of the substitute (0.125W vs. 0.1W) provides additional thermal margin without affecting circuit performance.

Mechanical Compatibility: Both parts utilize the 0805 (2012 Metric) package with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and height (0.024" maximum seated height). PCB footprints and assembly processes require no modification.

Regulatory Compliance: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. The substitute carries AEC-Q200 automotive qualification, which represents an additional quality assurance level applicable to general industrial applications.

Product Availability: The substitute part is in active production status with confirmed inventory, ensuring long-term procurement viability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD1111F10 be used as a direct replacement for RN732ATTD1111F10 in existing designs?

A: Yes. The substitute part is electrically and mechanically identical to the main part across all critical parameters. No circuit redesign or PCB layout modification is required. The higher power rating of the substitute (0.125W vs. 0.1W) is a compatible upward specification.

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

A: The RN73R2ATTD1111F10 is rated for 0.125W compared to the 0.1W rating of the RN732ATTD1111F10. This higher rating provides additional thermal headroom and does not negatively impact circuit performance. If the original design operates within the 0.1W specification, the substitute will perform identically with improved thermal margin.

Q: Are there packaging differences between the main part and substitute?

A: The main part is supplied in standard packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts use the identical 0805 (2012 Metric) package. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or compatibility.

Q: What does AEC-Q200 qualification mean for the substitute part?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. While the main part lacks this certification, the substitute's AEC-Q200 status indicates it meets stringent reliability requirements applicable to both automotive and general industrial applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the RN732ATTD1111F10 and RN73R2ATTD1111F10 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Why is the main part classified as obsolete?

A: The RN732ATTD1111F10 is no longer in active production. The RN73R2ATTD1111F10 represents the current production equivalent from KOA Speer Electronics, Inc., offering identical electrical performance with enhanced automotive qualification and active manufacturing support.
