Substitute Part Grouping Explanation

Substitution eligibility for the RN731ETTP2582C25 is determined by strict equivalence across the following critical parameters:

  • Resistance value: 25.8 kOhms
  • Tolerance: ±0.25%
  • Power rating: 0.063W (1/16W)
  • Package: 0402 (1005 Metric)
  • Composition: Thin Film
  • Temperature coefficient: ±25ppm/°C
  • Operating temperature range: -55°C ~ 155°C
  • Moisture resistance capability
  • RoHS3 compliance

The substitute part RN73R1ETTP2582C25 meets all these electrical and mechanical parameters. The primary distinction is that the substitute part carries AEC-Q200 automotive qualification, which represents an additional certification level rather than a deviation from the base specifications.

Frequently Asked Questions (FAQ)

Q: Can RN73R1ETTP2582C25 be used as a direct replacement for RN731ETTP2582C25?

A: Yes. Both parts share identical resistance value (25.8 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), composition (thin film), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute part is active and available, whereas the main part is obsolete.

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

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. This certification does not restrict use in non-automotive applications; it indicates additional quality assurance and testing protocols have been applied.

Q: Are the physical dimensions identical between the two parts?

A: Yes. 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).

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Is there any difference in RoHS compliance between the two parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting the same environmental and regulatory standards.
