Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F17R4CS is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 17.4 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)

Mechanical Compatibility Requirements:

• Package format: 2010 (5025 Metric) (exact match required)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)
• Number of terminations: 2 (exact match required)

Environmental & Compliance Requirements:

• Operating temperature range: -55°C ~ 155°C (exact match or superior range acceptable)
• RoHS3 compliance (required)
• Moisture sensitivity level: 1 (Unlimited) (exact match or superior acceptable)

Power Rating Consideration: The substitute part may have equal or higher power rating than the main part, provided all other parameters remain equivalent. Higher power ratings do not disqualify substitution in applications where the lower power rating is sufficient.

Engineering Selection Recommendations

RMCF2010FT17R4 (Stackpole Electronics Inc) Substitution Basis:

The RMCF2010FT17R4 qualifies as a direct substitute for the RC5025F17R4CS based on the following engineering criteria:

1. Electrical Specification Match: Identical resistance value (17.4 Ohms), tolerance (±1%), and temperature coefficient (±100ppm/°C) ensure functional equivalence in circuit applications.

2. Mechanical Compatibility: Both components utilize the 2010 (5025 Metric) package format with identical length and width dimensions (5.00mm x 2.50mm). The seated height difference (0.66mm vs. 0.70mm) is within typical PCB assembly tolerances and does not preclude substitution.

3. Power Rating Enhancement: The RMCF2010FT17R4 provides 0.75W (3/4W) rating compared to the RC5025F17R4CS 0.667W (2/3W) rating. This higher rating provides additional thermal margin without affecting electrical performance in applications designed for the lower rating.

4. Environmental & Compliance Alignment: Both components operate across the identical temperature range (-55°C ~ 155°C), maintain MSL 1 (Unlimited) moisture sensitivity rating, and achieve ROHS3 and REACH compliance.

5. Automotive Certification: The RMCF2010FT17R4 carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT17R4 replace RC5025F17R4CS in all applications?

A: Yes, the RMCF2010FT17R4 meets all critical electrical and mechanical parameters required for substitution. The higher power rating (0.75W vs. 0.667W) and automotive AEC-Q200 certification provide equivalent or enhanced performance characteristics.

Q: Does the 0.04mm height difference (0.70mm vs. 0.66mm) affect PCB assembly?

A: No. The 0.04mm height variance is within standard PCB assembly tolerances and does not impact component placement, soldering, or functional performance.

Q: Are both components RoHS3 compliant?

A: Yes. Both RC5025F17R4CS and RMCF2010FT17R4 are ROHS3 compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

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

A: AEC-Q200 is an automotive industry qualification standard. The RMCF2010FT17R4 carries this certification, indicating enhanced reliability testing and suitability for automotive applications. This does not restrict use in non-automotive applications.

Q: Are the packaging formats identical?

A: Both components use the 2010 (5025 Metric) package format with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm) dimensions, ensuring direct mechanical compatibility on PCB layouts.

Q: Can I use the substitute part if my design specifies the Samsung RC5025F17R4CS?

A: Substitution is technically valid based on electrical and mechanical equivalence. However, design specifications should be reviewed for any manufacturer-specific requirements or supply chain constraints that may necessitate the original part.
