Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD3012C50 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 30.1 kOhms
• Tolerance: ±0.25%
• 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 may be equal to or greater than the original specification (0.1W minimum)
• Product status may transition from obsolete to active
• Additional certifications (such as AEC-Q200) do not disqualify substitution

The RN73R2ATTD3012C50 meets all mandatory matching parameters and qualifies as a direct substitute with enhanced power rating (0.125W) and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD3012C50 is a qualified substitute for the obsolete RN732ATTD3012C50. Both components are manufactured by KOA Speer Electronics, Inc. and maintain identical electrical and mechanical specifications across all critical parameters.

The substitute part offers the following advantages:

• Active Product Status: The RN73R2ATTD3012C50 is currently in active production, ensuring long-term supply chain availability and support.
• Enhanced Power Rating: The increased power rating (0.125W versus 0.1W) provides additional thermal margin without affecting circuit performance.
• Automotive Qualification: AEC-Q200 certification qualifies this component for automotive applications, expanding its applicability across industry segments.
• Regulatory Compliance: Both ROHS3 and REACH compliance are maintained, ensuring environmental and regulatory requirements are satisfied.

Physical footprint, electrical performance, and thermal characteristics remain identical. Direct substitution is supported without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD3012C50 be used as a direct replacement for the RN732ATTD3012C50?

A: Yes. The RN73R2ATTD3012C50 meets all mandatory electrical and mechanical specifications. Resistance, tolerance, temperature coefficient, operating temperature range, package dimensions, and composition are identical. The substitute part is physically and functionally compatible without modification.

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

A: The RN732ATTD3012C50 is rated at 0.1W (1/10W), while the RN73R2ATTD3012C50 is rated at 0.125W (1/8W). The higher power rating of the substitute part does not affect circuit operation and provides additional thermal headroom in power dissipation scenarios.

Q: Are the physical dimensions identical?

A: Yes. Both components use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm), width (0.049" / 1.25mm), and maximum seated height (0.024" / 0.60mm). Board layout and assembly processes require no modification.

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

A: No. AEC-Q200 certification is an additional qualification that does not alter electrical or mechanical performance. It expands the component's applicability to automotive environments but does not restrict use in other applications.

Q: What is the packaging difference between these parts?

A: The RN732ATTD3012C50 packaging format is not specified in the provided data. The RN73R2ATTD3012C50 is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RN732ATTD3012C50 and RN73R2ATTD3012C50 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
