Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD3013D50 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 301 kOhms
• Tolerance: ±0.5%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Resistance: Required

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power rating
• Product Status: Active status preferred over obsolete
• Packaging Format: May differ (Tape & Reel vs. other formats)
• Certifications: Additional certifications (such as AEC-Q200) are allowable

The RN73R2ATTD3013D50 qualifies as a direct substitute based on these criteria. It maintains identical electrical specifications while offering higher power rating (0.125W vs. 0.1W) and active product status with automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD3013D50 is a direct functional equivalent to the RN732ATTD3013D50 for applications requiring 301 kOhms ±0.5% thin film resistors in 0805 package format.

Selection Basis:

The RN73R2ATTD3013D50 maintains all critical electrical and mechanical parameters of the original part. The increased power rating (0.125W vs. 0.1W) provides additional thermal margin without affecting circuit performance in applications designed for the original 0.1W specification.

The RN73R2ATTD3013D50 carries active product status from KOA Speer Electronics, Inc., ensuring continued availability and supply chain stability. This part includes AEC-Q200 automotive qualification, which represents an enhancement over the original specification and does not restrict use in non-automotive applications.

Both parts maintain identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited) classification, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD3013D50 be used as a direct replacement for the RN732ATTD3013D50?

A: Yes. The RN73R2ATTD3013D50 is a direct substitute. Both parts share identical resistance value (301 kOhms), tolerance (±0.5%), 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 is compatible with circuits designed for the original specification.

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

A: The RN732ATTD3013D50 is rated at 0.1W (1/10W), while the RN73R2ATTD3013D50 is rated at 0.125W (1/8W). The higher power rating of the substitute part provides additional thermal dissipation capability and does not affect electrical performance in applications designed for the lower-rated original part.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0805 (2012 Metric) format with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.024" (0.60mm). They are mechanically interchangeable on printed circuit boards.

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

A: AEC-Q200 is an automotive industry qualification standard. The RN73R2ATTD3013D50 meets this standard, indicating enhanced reliability testing and quality assurance. This certification does not restrict the part's use in non-automotive applications and represents a quality enhancement over the original specification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RN732ATTD3013D50 and RN73R2ATTD3013D50 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.
