Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD6901D10 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 6.9 kOhms
• Tolerance: ±0.5%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±10ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistant feature

Allowable Variation:

• Power rating may be equal to or greater than 0.1W
• Product status may transition from obsolete to active
• Additional certifications (such as AEC-Q200) may be present in substitute parts

The RN73R2ATTD6901D10 qualifies as a direct substitute based on full parameter alignment with the allowable variation criteria.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD6901D10 is a qualified substitute for the obsolete RN732ATTD6901D10 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical resistance value (6.9 kOhms), tolerance (±0.5%), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute part features a higher power rating (0.125W versus 0.1W), which provides additional thermal margin without affecting circuit performance.

Mechanical Compatibility: Both components utilize the 0805 (2012 Metric) package with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and maximum seated height (0.024" / 0.60mm). PCB footprints and assembly processes remain unchanged.

Compliance Status: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The substitute part carries AEC-Q200 automotive qualification, which represents an enhancement to the original specification without introducing incompatibility.

Supply Availability: The RN73R2ATTD6901D10 maintains active product status with current inventory availability, addressing the supply discontinuation of the obsolete RN732ATTD6901D10.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD6901D10 be used as a direct replacement for the RN732ATTD6901D10 in existing designs?

A: Yes. The RN73R2ATTD6901D10 qualifies as a direct substitute. Electrical parameters, package dimensions, and thermal characteristics are equivalent. The higher power rating (0.125W versus 0.1W) is compatible with all applications designed for the original 0.1W specification.

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

A: The RN73R2ATTD6901D10 is rated for 0.125W compared to the original 0.1W rating. This represents increased power dissipation capability and thermal headroom. In applications where the original part operated at or near its power limit, the substitute provides additional safety margin without altering electrical behavior.

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

A: No. AEC-Q200 qualification represents an additional quality and reliability standard applied to the substitute part. This certification does not introduce incompatibility; it enhances the part's suitability for demanding applications including automotive environments.

Q: Are the physical dimensions and PCB footprints identical?

A: Yes. Both parts conform to the 0805 (2012 Metric) package standard with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.024" / 0.60mm). No PCB redesign or assembly process modification is required.

Q: What is the packaging difference between the main part and substitute?

A: The RN732ATTD6901D10 packaging format is not specified in the provided data. The RN73R2ATTD6901D10 is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the RN732ATTD6901D10 and RN73R2ATTD6901D10 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.
