RC5025F3651CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F3651CS is a 3.65 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) continuous power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are necessary when the original RC5025F3651CS becomes unavailable, when alternative manufacturers are preferred for supply chain diversification, or when design requirements permit higher power ratings while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F3651CS is based on strict electrical and mechanical parameter matching:

Mandatory Matching Parameters:

• Resistance: 3.65 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 2010 (5025 Metric) (exact match required for PCB footprint compatibility)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature: -55°C ~ 155°C (exact match required)
• Moisture Resistance: Required feature
• RoHS Status: ROHS3 Compliant (exact match required)

Allowable Variation:

• Power Rating: Substitutes may have equal (0.667W) or higher power ratings (0.75W, 3/4W). Higher power ratings provide design margin and are electrically compatible in applications requiring 0.667W or less.
• MSL Rating: Substitutes must maintain MSL 1 (Unlimited) rating.

All four substitute parts meet these criteria and are therefore valid electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

RC2010FK-073K65L (YAGEO) is the direct upgrade substitute with Active product status. This part maintains all mandatory electrical parameters while providing increased power rating (0.75W vs. 0.667W), offering design margin for thermal performance. YAGEO is an established manufacturer with consistent supply availability.

CRCW20103K65FKEF (Vishay Dale) and RMCF2010FT3K65 (Stackpole Electronics) are functionally equivalent alternatives with Active product status. Both incorporate AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. These parts are suitable for designs with automotive or high-reliability requirements.

Secondary Substitute (Legacy Status):

ERJ-12SF3651U (Panasonic Electronic Components) is electrically and mechanically equivalent but carries "Not For New Designs" product status. This part is suitable only for replacement or repair of existing assemblies using the original specification. New designs should not incorporate this part number.

Selection Criteria:

• For new designs with standard reliability requirements: RC2010FK-073K65L (YAGEO)
• For automotive or high-reliability applications: CRCW20103K65FKEF (Vishay Dale) or RMCF2010FT3K65 (Stackpole Electronics)
• For legacy system maintenance only: ERJ-12SF3651U (Panasonic) when original part is unavailable

All substitute parts are ROHS3 compliant and maintain MSL 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher power rating (0.75W) in place of the original 0.667W part?

A: Yes. The 0.75W (3/4W) rated substitutes are electrically compatible in all applications designed for 0.667W (2/3W) or lower power dissipation. Higher power ratings provide thermal margin and do not affect circuit performance. The physical package dimensions remain identical (2010 / 5025 Metric), ensuring PCB footprint compatibility.

Q: Are all substitute parts suitable for new product designs?

A: Three of the four substitutes are suitable for new designs: RC2010FK-073K65L (YAGEO), CRCW20103K65FKEF (Vishay Dale), and RMCF2010FT3K65 (Stackpole Electronics) all carry Active product status. ERJ-12SF3651U (Panasonic) is marked "Not For New Designs" and should be used only for replacement of existing assemblies.

Q: Do the substitute parts maintain the same moisture resistance and temperature performance?

A: Yes. All substitute parts are moisture-resistant thick film resistors with identical temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C). Moisture sensitivity level (MSL 1 - Unlimited) is maintained across all parts, ensuring equivalent handling and storage requirements.

Q: What is the difference between automotive-rated and non-automotive-rated substitutes?

A: CRCW20103K65FKEF (Vishay Dale) and RMCF2010FT3K65 (Stackpole Electronics) carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and testing standards. RC2010FK-073K65L (YAGEO) does not specify automotive qualification. For applications requiring automotive-grade components, select the AEC-Q200 qualified parts. For standard industrial applications, all parts are equivalent.

Q: Will the substitute parts fit the same PCB footprint as the original RC5025F3651CS?

A: Yes. All substitute parts use the identical 2010 (5025 Metric) package format with matching dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and similar maximum seated heights (0.026" to 0.028"). PCB footprints and assembly processes require no modification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts are ROHS3 compliant, matching the original RC5025F3651CS specification. This ensures compatibility with regulatory requirements and standard procurement specifications.
