Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD8563C50 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 856 kOhms
• Tolerance: ±0.25%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistant feature

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power rating (0.1W or greater)
• Product Status: Active or Obsolete
• Packaging format: Different packaging configurations (Tape & Reel vs. bulk)
• Additional certifications: Automotive AEC-Q200 qualification does not disqualify substitution

The RN73R2ATTD8563C50 qualifies as a direct substitute because it maintains all mandatory matching parameters while offering a higher power rating (0.125W vs. 0.1W) and active product status with automotive qualification.

Engineering Selection Recommendations

The RN73R2ATTD8563C50 is the qualified substitute for the obsolete RN732ATTD8563C50. Selection is based on the following engineering criteria:

Product Status Consideration: The RN732ATTD8563C50 is obsolete, making the active RN73R2ATTD8563C50 the appropriate long-term solution for ongoing production and inventory management.

Electrical Compatibility: Both parts maintain identical resistance (856 kOhms), tolerance (±0.25%), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute's higher power rating (0.125W vs. 0.1W) provides additional thermal margin without affecting circuit performance.

Mechanical Compatibility: Identical 0805 (2012 Metric) package dimensions and termination configuration ensure direct PCB footprint compatibility with no layout modifications required.

Compliance Status: Both parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating. The substitute includes automotive AEC-Q200 qualification, which does not restrict use in non-automotive applications.

Packaging Availability: The substitute is available in Tape & Reel (TR) format with 616 pieces in stock, compared to the main part's limited obsolete inventory of 935 pieces.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD8563C50 be used as a direct replacement for RN732ATTD8563C50 on existing PCBs?

A: Yes. Both parts share identical 0805 (2012 Metric) package dimensions, footprint, and termination configuration. No PCB modifications are required for substitution.

Q: What is the difference between the 0.1W and 0.125W power ratings?

A: The RN73R2ATTD8563C50 has a higher power dissipation rating (0.125W vs. 0.1W). This provides additional thermal capacity and does not negatively impact circuit operation. The substitute can safely handle the same or lower power dissipation levels as the original part.

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

A: Yes. Both parts have 856 kOhms resistance, ±0.25% tolerance, ±50ppm/°C temperature coefficient, and -55°C ~ 155°C operating temperature range. Electrical performance is equivalent.

Q: Does the automotive AEC-Q200 qualification on the substitute affect non-automotive applications?

A: No. AEC-Q200 qualification indicates the part meets automotive reliability standards and does not restrict its use in other applications. It represents an additional quality assurance level.

Q: What is the significance of the obsolete status of the main part?

A: Obsolete status indicates the RN732ATTD8563C50 is no longer manufactured and inventory is limited. The RN73R2ATTD8563C50 is an active product with ongoing manufacturing support and availability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RN732ATTD8563C50 and RN73R2ATTD8563C50 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging formats are available for the substitute?

A: The RN73R2ATTD8563C50 is available in Tape & Reel (TR) format, suitable for automated assembly processes. The main part was available in standard packaging configurations.
