Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN731ETTP2202D50 is determined by strict equivalence across the following parameters:

• Resistance value: 22 kOhms
• Tolerance: ±0.5%
• Power rating: 0.063W (1/16W)
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture resistant construction
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The substitute part RN73R1ETTP2202D50 meets all these electrical and mechanical parameters. The primary distinction is product status and additional automotive qualification (AEC-Q200), which represents an enhancement rather than a deviation from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The RN73R1ETTP2202D50 is a direct functional equivalent to the RN731ETTP2202D50. Both parts are manufactured by KOA Speer Electronics, Inc., and share identical electrical specifications, package geometry, and environmental ratings.

The RN73R1ETTP2202D50 carries active product status, ensuring continued availability and supply chain support. This part includes AEC-Q200 automotive qualification, which represents an additional qualification level beyond the original part specification. For applications requiring automotive-grade reliability, this qualification provides enhanced qualification documentation and traceability.

Frequently Asked Questions (FAQ)

Q: Can RN73R1ETTP2202D50 be used as a direct replacement for RN731ETTP2202D50?

A: Yes. Both parts share identical resistance value (22 kOhms), tolerance (±0.5%), power rating (0.063W), package (0402), composition (thin film), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). Electrical and mechanical compatibility is complete.

Q: What is the difference between these two parts?

A: The primary differences are product status and automotive qualification. RN731ETTP2202D50 is obsolete, while RN73R1ETTP2202D50 is active. RN73R1ETTP2202D50 includes AEC-Q200 automotive qualification, which is not present in the original part.

Q: Are there any package or footprint differences?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints are identical.

Q: Does the AEC-Q200 qualification affect compatibility?

A: No. AEC-Q200 is an additional qualification that enhances reliability documentation for automotive applications. It does not alter electrical performance or mechanical compatibility. The part remains suitable for all applications where the original part was specified.

Q: Are moisture handling requirements the same?

A: Yes. Both parts carry MSL 1 (Unlimited) rating and moisture resistant construction. No special moisture bake procedures are required for either part prior to assembly.
