Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD3012D10 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 30.1 kOhms
• Tolerance: ±0.5%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±10ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: The substitute part may have equal or higher power dissipation capacity than the original 0.1W specification, provided all other electrical and mechanical parameters remain identical.

The RN73R2ATTD3012D10 qualifies as a direct substitute based on full alignment of all mandatory parameters. The substitute part exhibits a higher power rating (0.125W versus 0.1W), which represents an upward-compatible specification change that does not compromise circuit performance or reliability.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD3012D10 is the qualified substitute for the obsolete RN732ATTD3012D10 based on the following engineering criteria:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current manufacturing standards. The substitute part carries Active product status, providing assured long-term availability and supply chain continuity compared to the Obsolete original part.

Electrical and Mechanical Compatibility: The substitute part maintains identical resistance value (30.1 kOhms), tolerance (±0.5%), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). Physical dimensions and package format (0805 / 2012 Metric) are identical, enabling direct board-level substitution without layout modifications.

Power Rating Enhancement: The substitute part provides 0.125W (1/8W) power rating compared to the original 0.1W specification. This represents an upward-compatible change that increases thermal margin and reliability in the application circuit without introducing incompatibility.

Automotive Qualification: The RN73R2ATTD3012D10 includes AEC-Q200 automotive qualification, providing additional quality assurance and reliability documentation beyond the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD3012D10 be used as a direct replacement for the RN732ATTD3012D10 on existing PCBs?

A: Yes. The substitute part is mechanically and electrically compatible. Both parts use identical 0805 (2012 Metric) package format with matching physical dimensions (0.079" L x 0.049" W, 0.024" max height). No PCB layout modifications are required.

Q: What is the significance of the higher power rating on the substitute part?

A: The RN73R2ATTD3012D10 is rated for 0.125W (1/8W) compared to the original 0.1W rating. This higher power dissipation capacity provides additional thermal margin and does not create incompatibility. The substitute part can safely operate in circuits designed for the lower-rated original component.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts are ROHS3 compliant and REACH Unaffected. The substitute part includes AEC-Q200 automotive qualification, which represents an additional quality certification. Both parts maintain identical Moisture Sensitivity Level 1 (Unlimited) rating.

Q: Why is the original RN732ATTD3012D10 marked as Obsolete?

A: The Obsolete status indicates the part is no longer in active production. The RN73R2ATTD3012D10 represents the current active equivalent from the same manufacturer, ensuring continued availability and supply chain support.

Q: Are the electrical characteristics identical between the two parts?

A: Yes. Both parts maintain 30.1 kOhms resistance value with ±0.5% tolerance, ±10ppm/°C temperature coefficient, and -55°C ~ 155°C operating temperature range. Electrical performance is equivalent.

Q: What packaging format is available for the substitute part?

A: The RN73R2ATTD3012D10 is supplied in Tape & Reel (TR) packaging format, standard for high-volume production environments.
