Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD11R1F50 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 11.1 Ohms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistance: Required

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power ratings (0.1W or greater)
• Product Status: Active status preferred for long-term availability
• Packaging Format: May differ (Tape & Reel vs. other formats)
• Additional Certifications: Automotive or industrial ratings may be present in substitutes

The RN73R2ATTD11R1F50 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD11R1F50 is a direct functional equivalent to the RN732ATTD11R1F50. Both components share identical electrical specifications (11.1 Ohms, ±1% tolerance, ±50ppm/°C temperature coefficient) and mechanical compatibility (0805 package, identical dimensions and termination count).

The primary distinction is product status: the RN732ATTD11R1F50 is obsolete, while the RN73R2ATTD11R1F50 maintains active status with ongoing manufacturer support. The substitute part incorporates Automotive AEC-Q200 qualification, providing additional reliability assurance for applications requiring automotive-grade components.

The RN73R2ATTD11R1F50 features a higher power rating (0.125W vs. 0.1W), which presents no compatibility constraint in applications designed for the original part. Both components maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

For procurement and design continuity, the RN73R2ATTD11R1F50 is the recommended replacement, offering superior long-term availability and active manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD11R1F50 be used as a direct replacement for the RN732ATTD11R1F50?

A: Yes. Both components share identical resistance (11.1 Ohms), tolerance (±1%), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 155°C), package (0805), and physical dimensions. The substitute part is electrically and mechanically compatible.

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

A: The RN732ATTD11R1F50 is rated at 0.1W (1/10W), while the RN73R2ATTD11R1F50 is rated at 0.125W (1/8W). The higher power rating of the substitute part does not create compatibility issues in applications designed for the original component.

Q: Why is the RN732ATTD11R1F50 listed as obsolete?

A: The RN732ATTD11R1F50 has been discontinued by the manufacturer. The RN73R2ATTD11R1F50 represents the active equivalent in the KOA Speer Electronics product line.

Q: Are there packaging differences between these parts?

A: The main part is supplied in standard packaging, while the substitute (RN73R2ATTD11R1F50) is available in Tape & Reel (TR) format. Both use identical 0805 (2012 Metric) package specifications.

Q: Does the RN73R2ATTD11R1F50 meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level). The substitute part additionally qualifies to Automotive AEC-Q200 standard.

Q: Can these parts be used interchangeably on PCBs?

A: Yes. Identical package dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and height (0.024" maximum) ensure mechanical and footprint compatibility on printed circuit boards.
