Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD8352F100 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 83.5 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistant Feature: Required

Allowable Variation Parameters:

• Power Rating: May be equal to or greater than 0.1W
• Packaging Format: May differ (bulk, tape & reel, etc.)
• Product Status: Active or Obsolete
• Automotive Certification: May be added without restriction

The RN73R2ATTD8352F100 qualifies as a direct substitute because it maintains all mandatory matching parameters while offering an increased power rating of 0.125W (1/8W) and includes automotive AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD8352F100 is a direct functional substitute for the RN732ATTD8352F100 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical resistance value (83.5 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The increased power rating of the substitute (0.125W versus 0.1W) provides additional thermal margin without affecting circuit performance.

Physical Compatibility: Both components utilize the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W) and seated height (0.024" max). Direct footprint compatibility is confirmed.

Compliance Status: Both parts are ROHS3 compliant and REACH unaffected. The substitute includes automotive AEC-Q200 certification, which does not restrict use in non-automotive applications.

Supply Availability: The RN73R2ATTD8352F100 is classified as Active, ensuring continued availability and supply chain support compared to the obsolete status of the original part.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD8352F100 be used as a direct replacement for the RN732ATTD8352F100?

A: Yes. Both parts share identical electrical specifications (83.5 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and physical dimensions (0805 package). The substitute offers increased power rating (0.125W versus 0.1W) and automotive certification, both of which are compatible with the original application requirements.

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

A: The RN732ATTD8352F100 is rated at 0.1W (1/10W), while the RN73R2ATTD8352F100 is rated at 0.125W (1/8W). The higher power rating of the substitute provides additional thermal dissipation capability without changing electrical performance or physical footprint.

Q: Are there packaging differences between these parts?

A: The main part (RN732ATTD8352F100) does not specify packaging format in the provided data. The substitute (RN73R2ATTD8352F100) is supplied in Tape & Reel (TR) format. Both parts use the 0805 (2012 Metric) package case, ensuring physical compatibility on PCBs.

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

A: No. Automotive AEC-Q200 certification indicates enhanced reliability and quality standards. This certification does not restrict the part's use in non-automotive applications and may provide additional confidence in component reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both the RN732ATTD8352F100 and RN73R2ATTD8352F100 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the original part listed as obsolete?

A: The RN732ATTD8352F100 is classified as obsolete, indicating that KOA Speer Electronics, Inc. has discontinued active production. The RN73R2ATTD8352F100 remains in active production status, providing a viable path for continued component sourcing and design support.
