RC5025F5901CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F5901CS is a 5.9 kOhm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is classified as Active product status with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. Alternative sources become necessary for supply chain optimization, lead time management, or design flexibility while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F5901CS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance value: 5.9 kOhms
• Tolerance: ±1%
• Package footprint: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Allowable Variation: Power rating may exceed the original 0.667W specification, provided the substitute maintains all other electrical and mechanical parameters. Substitute parts rated at 0.75W (3/4W) are functionally equivalent as they operate within the same thermal and electrical envelope while providing additional power dissipation margin.

Parameter Comparison

Engineering Selection Recommendations

CRCW20105K90FKEF (Vishay Dale) is the primary substitute for the RC5025F5901CS. This part maintains all critical electrical parameters while providing 0.75W power rating. The component is Active product status, ROHS3 compliant, and carries AEC-Q200 automotive qualification. Inventory availability is substantial at 12,628 pieces. The seated height of 0.028" (0.70mm) represents a 0.002" (0.04mm) increase over the original part, which remains within typical PCB design tolerances for 2010 package applications.

ERJ-12SF5901U (Panasonic Electronic Components) is a secondary substitute option. This part is electrically and mechanically equivalent to the RC5025F5901CS with identical resistance, tolerance, temperature coefficient, and operating range. However, the product status is classified as "Not For New Designs," indicating this part is in mature or declining production phase. The ERJ-12SF5901U carries AEC-Q200 automotive qualification and maintains ROHS3 compliance. This part is suitable for replacement or repair applications where existing designs already incorporate this component, but should not be selected for new product development.

Both substitute parts are compatible with the 2010 (5025 Metric) package footprint and present no mechanical or electrical conflicts with the original RC5025F5901CS specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW20105K90FKEF replace RC5025F5901CS in all applications?

A: Yes. The CRCW20105K90FKEF maintains identical resistance (5.9 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The increased power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance. Both parts are ROHS3 compliant with MSL 1 rating and identical package footprint.

Q: What is the difference in physical dimensions between these parts?

A: The length and width are identical at 0.197" L x 0.098" W (5.00mm x 2.50mm). The seated height differs slightly: RC5025F5901CS is 0.026" (0.66mm) maximum, while both CRCW20105K90FKEF and ERJ-12SF5901U are 0.028" (0.70mm) maximum. This 0.002" (0.04mm) difference is within standard PCB design clearance tolerances for 2010 package applications.

Q: Why is ERJ-12SF5901U marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase with potential for discontinuation. While the component is fully functional and equivalent to the RC5025F5901CS, Panasonic recommends using alternative sources for new product development. The ERJ-12SF5901U remains suitable for repair, replacement, or legacy system applications.

Q: Are all three parts automotive qualified?

A: The CRCW20105K90FKEF and ERJ-12SF5901U both carry AEC-Q200 automotive qualification. The RC5025F5901CS does not list AEC-Q200 qualification in the provided specifications. If automotive qualification is a design requirement, CRCW20105K90FKEF is the appropriate selection.

Q: What packaging formats are available for these parts?

A: RC5025F5901CS is supplied in standard packaging format. CRCW20105K90FKEF and ERJ-12SF5901U are supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.
