Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD9103C25 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 910 kOhms
• Tolerance: ±0.25%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistant feature

Allowable Variation:

• Power rating may be equal to or greater than the original 0.1W specification, provided the physical dimensions remain compatible with the 0805 package footprint

The RN73R2ATTD9103C25 meets all mandatory matching parameters and represents a direct functional substitute with enhanced power rating (0.125W) and automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD9103C25 is the direct equivalent substitute for the obsolete RN732ATTD9103C25. Both components share identical electrical specifications (910 kOhms, ±0.25% tolerance, ±25ppm/°C temperature coefficient) and physical dimensions (0805 package, 2.00mm x 1.25mm).

The substitute part offers the following advantages:

• Active Product Status: The RN73R2ATTD9103C25 is currently in active production, ensuring long-term availability and supply chain continuity.
• Enhanced Power Rating: The 0.125W (1/8W) rating exceeds the original 0.1W specification, providing additional thermal margin in applications without requiring circuit redesign.
• Automotive Qualification: AEC-Q200 certification qualifies this component for automotive applications, expanding its use case scope.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status.

Direct substitution is permissible without circuit modification, as the substitute part maintains all critical electrical and mechanical parameters while offering improved product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD9103C25 be used as a direct replacement for the RN732ATTD9103C25?

A: Yes. Both components share identical resistance (910 kOhms), tolerance (±0.25%), temperature coefficient (±25ppm/°C), package format (0805), and operating temperature range (-55°C ~ 155°C). The substitute part is electrically and mechanically compatible without circuit modification.

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

A: The main part is rated at 0.1W (1/10W), while the substitute is rated at 0.125W (1/8W). The higher power rating of the substitute provides additional thermal capacity and does not negatively impact circuit performance in applications designed for the original 0.1W component.

Q: Why is the RN732ATTD9103C25 listed as obsolete?

A: The RN732ATTD9103C25 has been discontinued by the manufacturer. The RN73R2ATTD9103C25 represents the active production equivalent, ensuring continued availability for new designs and replacement inventory.

Q: Are there any package or footprint differences between these parts?

A: No. Both components use the 0805 (2012 Metric) package with identical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.024" (0.60mm). PCB footprints are interchangeable.

Q: Does the substitute part meet the same compliance standards?

A: Yes. The RN73R2ATTD9103C25 is ROHS3 compliant and REACH unaffected, matching the regulatory status of the original part. Additionally, it carries AEC-Q200 automotive qualification.

Q: What is the moisture sensitivity level for both parts?

A: Both components have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
