Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD8763C50 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 876 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:

• Power rating may be equal to or greater than 0.1W
• Product status may differ (active vs. obsolete)
• Packaging format may vary (bulk vs. Tape & Reel)
• Additional certifications (such as AEC-Q200) do not disqualify a substitute

The RN73R2ATTD8763C50 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD8763C50 is a qualified substitute for the obsolete RN732ATTD8763C50 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical resistance (876 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.

Physical Compatibility: Both components utilize the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and height (0.024" maximum seated height). Direct PCB substitution is possible without layout modification.

Compliance and Certifications: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The substitute carries AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications and indicates enhanced reliability screening.

Supply Continuity: The RN73R2ATTD8763C50 is actively manufactured by KOA Speer Electronics, Inc., ensuring long-term availability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD8763C50 be used as a direct replacement for the RN732ATTD8763C50 without circuit redesign?

A: Yes. Both parts share identical electrical specifications (876 kOhms ±0.25%, ±50ppm/°C, -55°C ~ 155°C operating range) and physical package (0805 2012 Metric). The substitute's higher power rating (0.125W) is compatible with applications designed for 0.1W. No circuit modification is required.

Q: What is the significance of the AEC-Q200 certification on the substitute part?

A: AEC-Q200 is an automotive qualification standard indicating the part has undergone enhanced reliability testing and screening. This certification does not restrict use in non-automotive applications and reflects higher manufacturing quality standards.

Q: Are there any differences in moisture resistance between the two parts?

A: Both parts feature moisture-resistant thin film construction and carry identical MSL 1 (Unlimited) ratings. Moisture sensitivity performance is equivalent.

Q: Does the substitute part's higher power rating affect circuit behavior?

A: No. The substitute's 0.125W rating is higher than the main part's 0.1W rating. In applications where the main part dissipates 0.1W or less, the substitute operates within its power envelope with additional thermal margin, improving reliability without altering electrical performance.

Q: What packaging formats are available for the substitute part?

A: The RN73R2ATTD8763C50 is supplied in Tape & Reel (TR) format, which is the standard production packaging for high-volume applications. Bulk packaging availability should be confirmed with the supplier.

Q: Are both parts RoHS compliant?

A: Yes. Both the RN732ATTD8763C50 and RN73R2ATTD8763C50 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
