Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F17R8CS is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 17.8 Ohms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Composition: Thick Film
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration: Power rating may vary within the same package footprint. The RC5025F17R8CS is rated at 0.667W (2/3W). Substitute parts rated at 0.75W (3/4W) or higher maintain electrical compatibility while providing equal or greater power dissipation capability in the identical 2010 package.

All identified substitutes maintain identical mechanical dimensions, thermal characteristics, and environmental compliance specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW201017R8FKEF, ERJ-12SF17R8U, or RMCF2010FT17R8 be used as direct replacements for RC5025F17R8CS?

A: Yes. All three substitute parts maintain identical resistance value (17.8 Ohms), tolerance (±1%), package footprint (2010/5025 Metric), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and environmental compliance (ROHS3, MSL 1). The substitute parts feature increased power ratings (0.75W vs. 0.667W), which provides equal or greater performance capability in the same physical package.

Q: What is the difference in physical dimensions between the main part and substitutes?

A: The RC5025F17R8CS has a maximum seated height of 0.026" (0.66mm). The three substitute parts have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within typical PCB assembly tolerances and does not affect mechanical compatibility or board-level integration.

Q: Are the substitute parts suitable for automotive applications?

A: CRCW201017R8FKEF and RMCF2010FT17R8 carry AEC-Q200 automotive qualification. ERJ-12SF17R8U also carries AEC-Q200 qualification but is classified as Not For New Designs. The RC5025F17R8CS does not specify automotive qualification. For automotive applications, CRCW201017R8FKEF or RMCF2010FT17R8 are the appropriate selections.

Q: Why do the substitute parts have higher power ratings?

A: The 2010 (5025 Metric) package can accommodate resistors rated at 0.75W (3/4W) or higher while maintaining identical external dimensions. The substitute parts utilize improved thermal management or material composition within the same package envelope, resulting in higher power dissipation capability. This provides design margin without requiring package size changes.

Q: Which substitute part should be selected for new designs?

A: For new designs, select either CRCW201017R8FKEF (Vishay Dale) or RMCF2010FT17R8 (Stackpole Electronics Inc), both with Active product status. ERJ-12SF17R8U should not be selected for new designs due to its Not For New Designs classification.

Q: Are all parts RoHS3 compliant?

A: Yes. The RC5025F17R8CS and all three substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the packaging format for each part?

A: RC5025F17R8CS is supplied in standard packaging format. CRCW201017R8FKEF is available in Cut Tape (CT) & Digi-Reel® or Tape & Reel (TR) formats. ERJ-12SF17R8U and RMCF2010FT17R8 are supplied in Tape & Reel (TR) format. Verify packaging requirements with your procurement specifications.
