Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0717R8L is determined by the following critical parameters:

  • Resistance Value: Must be 17.8 Ohms (exact match required)
  • Package Type: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
  • Composition: Thin film construction ensures performance consistency
  • Operating Temperature Range: Must support -55°C to 155°C minimum
  • RoHS Compliance: ROHS3 Compliant status required for regulatory alignment

The substitute part 5-1625868-1 (TE Connectivity Passive Product) meets all mandatory substitution criteria. While this substitute offers enhanced specifications (±0.1% tolerance versus ±1%, and 0.25W power rating versus 0.125W), these improvements represent upward compatibility and do not compromise circuit functionality.

Engineering Selection Recommendations

Both the RT0805FRE0717R8L and 5-1625868-1 are active production components with ROHS3 compliance and MSL Level 1 rating, confirming suitability for standard manufacturing and storage conditions without moisture bake-out requirements.

The 5-1625868-1 substitute provides measurable performance advantages: tighter tolerance (±0.1% versus ±1%) and higher power dissipation capability (0.25W versus 0.125W). These characteristics make it suitable for applications requiring enhanced precision or thermal margin. The improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) reduces drift over the operating temperature range.

Selection between these parts should be based on application-specific requirements for tolerance, power dissipation, and thermal stability rather than functional compatibility, as both components are electrically and mechanically interchangeable in the 0805 package format.

Frequently Asked Questions (FAQ)

Q: Can 5-1625868-1 be used as a direct replacement for RT0805FRE0717R8L?

A: Yes. Both components have identical resistance values (17.8 Ohms), package format (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The substitute meets or exceeds all electrical and mechanical specifications of the original part.

Q: What are the key differences between these parts?

A: The substitute offers three performance improvements: tolerance of ±0.1% compared to ±1%, power rating of 0.25W versus 0.125W, and temperature coefficient of ±25ppm/°C versus ±50ppm/°C. These represent enhanced capabilities that do not affect interchangeability.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both components operate across the identical temperature range of -55°C to 155°C. The substitute's lower temperature coefficient provides better resistance stability across this range.

Q: Do these parts require different handling or storage procedures?

A: No. Both components have MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity concerns. Standard component storage and handling procedures apply to both parts.

Q: Can the substitute be used in applications where the original part is specified?

A: Yes. The substitute's superior tolerance and power rating ensure compatibility with any circuit designed for the RT0805FRE0717R8L. No circuit redesign or validation is required for substitution.
