Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD3013C50 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 301 kOhms
• Tolerance: ±0.25%
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture resistance feature
• RoHS3 compliance

Allowable Variation:

• Power rating may be equal or higher than 0.1W
• Product status may differ (active vs. obsolete)
• Packaging format (bulk vs. tape & reel) may differ
• Additional certifications (such as AEC-Q200) do not disqualify substitution

The RN73R2ATTD3013C50 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD3013C50 is a direct substitute for the RN732ATTD3013C50 based on electrical and mechanical parameter equivalence.

Advantages of substitution:

• The RN73R2ATTD3013C50 maintains active product status, ensuring long-term availability and supply chain continuity
• Power rating is increased from 0.1W to 0.125W, providing additional thermal margin without affecting circuit performance
• Automotive AEC-Q200 certification provides enhanced reliability qualification
• Identical physical dimensions and electrical characteristics ensure drop-in compatibility

Compliance status: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD3013C50 be used as a direct replacement for the RN732ATTD3013C50?

A: Yes. Both resistors share identical resistance (301 kOhms), tolerance (±0.25%), package format (0805), composition (thin film), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part has a higher power rating (0.125W vs. 0.1W), which does not compromise circuit function.

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

A: The RN73R2ATTD3013C50 is rated at 0.125W compared to the original 0.1W rating. This higher power rating provides additional thermal headroom and does not negatively impact circuit performance. The component will operate within safe thermal limits under identical electrical conditions.

Q: Are there packaging differences between these parts?

A: The main part (RN732ATTD3013C50) is supplied in standard packaging, while the substitute (RN73R2ATTD3013C50) is supplied in Tape & Reel (TR) format. Both use identical 0805 (2012 Metric) package dimensions and are mechanically interchangeable on PCBs.

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

A: No. AEC-Q200 is an automotive qualification standard that indicates enhanced reliability testing. Its presence on the substitute part does not create incompatibility; it represents an additional quality assurance level that may benefit applications requiring automotive-grade components.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RN732ATTD3013C50 and RN73R2ATTD3013C50 are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited), indicating no moisture-related handling restrictions.
