Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0717R4L is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 17.4 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (physical and electrical compatibility)
• Composition: Thin Film (performance characteristics and stability)
• Operating temperature range: -55°C to 155°C (minimum requirement)

Allowable Variations (Enhancement Parameters):

• Tolerance: May be equal to or better than ±1%
• Power rating: May be equal to or greater than 0.125W
• Temperature coefficient: May be equal to or better than ±50ppm/°C
• RoHS and MSL compliance: Must meet or exceed original specifications

The substitute part 5-1625868-0 (TE Connectivity) meets all mandatory matching criteria and provides enhanced specifications in tolerance (±0.1%), power rating (0.25W), and temperature coefficient (±25ppm/°C), making it a valid direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RT0805FRE0717R4L and 5-1625868-0 are electrically and mechanically interchangeable for 0805 thin film resistor applications requiring 17.4 Ohms nominal resistance. Both components are ROHS3 compliant, carry MSL 1 rating, and operate across the full -55°C to 155°C temperature range.

Selection between these parts should be based on application-specific requirements:

• RT0805FRE0717R4L is suitable for standard precision applications where ±1% tolerance and ±50ppm/°C temperature coefficient meet circuit specifications.
• 5-1625868-0 is appropriate for applications requiring tighter tolerance control (±0.1%), lower temperature drift (±25ppm/°C), or higher power dissipation capability (0.25W vs. 0.125W).

Both parts maintain identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and are compatible with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 5-1625868-0 be used as a direct replacement for RT0805FRE0717R4L?

A: Yes. Both components share identical resistance value (17.4 Ohms), package type (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The substitute part offers enhanced specifications in tolerance and temperature coefficient, making it functionally compatible for direct substitution.

Q: What are the physical compatibility considerations?

A: Both parts use the 0805 (2012 Metric) package with identical footprint dimensions (2.00mm x 1.25mm). Maximum seated heights differ slightly (0.60mm vs. 0.65mm), which is within standard PCB assembly tolerances and does not affect compatibility.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. The substitute part has REACH status listed as "Vendor Undefined" compared to "REACH Unaffected" for the original part. Both maintain equivalent environmental compliance for standard applications.

Q: When should the higher power rating of 5-1625868-0 be considered?

A: The 0.25W rating of 5-1625868-0 provides additional thermal margin in applications where resistor power dissipation approaches or exceeds 0.125W. This is particularly relevant in high-current signal paths or precision measurement circuits where thermal stability is critical.

Q: How do temperature coefficients affect circuit performance?

A: The ±25ppm/°C coefficient of 5-1625868-0 provides superior temperature stability compared to the ±50ppm/°C of RT0805FRE0717R4L. In circuits spanning the full -55°C to 155°C operating range, this results in reduced resistance drift and improved measurement accuracy or signal fidelity.
