Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD3012F10 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 30.1 kOhms
• Tolerance: ±1%
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture resistance: Required
• RoHS3 compliance: Required

Allowable Variation:

• Power rating: May be equal to or greater than 0.1W
• Product status: Active status preferred for obsolete parts
• Packaging format: May differ (bulk to tape & reel conversion acceptable)
• Additional certifications: May be present without affecting substitution validity

The RN73R2ATTD3012F10 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD3012F10 is a valid substitute for the obsolete RN732ATTD3012F10 based on electrical and mechanical parameter equivalence.

Substitution Basis:

The RN73R2ATTD3012F10 maintains identical resistance value, tolerance, package dimensions, and thermal characteristics. The increased power rating of 0.125W (1/8W) compared to the original 0.1W (1/10W) provides additional thermal margin without affecting circuit performance. Both components are ROHS3 compliant and feature identical moisture sensitivity levels.

Product Status Advantage:

The RN73R2ATTD3012F10 carries active product status, ensuring continued availability and supply chain support. This addresses the obsolescence of the original part while maintaining full functional and mechanical compatibility.

Certification Consideration:

The RN73R2ATTD3012F10 includes AEC-Q200 automotive qualification. This certification does not restrict use in non-automotive applications and provides additional quality assurance documentation.

Packaging Consideration:

The substitute part is supplied in Tape & Reel (TR) packaging format, whereas the original part packaging format was not specified. Both formats contain identical components and are suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD3012F10 be used as a direct replacement for the RN732ATTD3012F10?

A: Yes. The RN73R2ATTD3012F10 meets all electrical and mechanical specifications required for direct substitution. Resistance value, tolerance, package format, temperature coefficient, and operating temperature range are identical. The increased power rating provides additional thermal capability without affecting circuit operation.

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

A: The RN73R2ATTD3012F10 is rated at 0.125W (1/8W) compared to the original 0.1W (1/10W). This higher rating indicates greater thermal dissipation capability. In applications where the original part operated at or near its power limit, the substitute provides additional safety margin. In applications where the original part operated well below its power limit, the higher rating has no negative effect.

Q: Does the AEC-Q200 automotive certification on the substitute part affect its use in non-automotive applications?

A: No. AEC-Q200 certification represents an additional quality and reliability standard. Components meeting automotive standards are suitable for use in any application. The presence of this certification does not restrict or modify the component's electrical or mechanical characteristics.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both components are 0805 (2012 Metric) package format with identical length, width, and maximum seated height specifications. They are mechanically interchangeable on printed circuit boards and compatible with identical assembly processes.

Q: What is the difference between the packaging formats listed?

A: The original part packaging format was not specified in the documentation. The substitute part is supplied in Tape & Reel (TR) format, which is standard for automated assembly operations. Both formats contain the same component; the difference is only in the delivery and handling method.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RN732ATTD3012F10 and RN73R2ATTD3012F10 are ROHS3 compliant and feature identical Moisture Sensitivity Level 1 (Unlimited) ratings.
