RC5025F2370CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F2370CS is a 237 Ohm ±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 and features moisture-resistant construction suitable for general industrial applications. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, temperature coefficient) and mechanical compatibility (package size, termination count, operating temperature range). Higher power-rated alternatives are available from qualified manufacturers for applications requiring increased thermal headroom.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F2370CS are qualified based on the following criteria:

Electrical Compatibility:

• Resistance value: 237 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility:

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

Regulatory Compliance:

• RoHS3 compliance (required)
• Moisture sensitivity level: 1 (Unlimited) (required)

Power Rating Consideration: The RC5025F2370CS operates at 0.667W (2/3W). Substitute parts rated at 0.75W (3/4W) provide increased power dissipation capability within the same package footprint and are electrically and mechanically compatible. Higher power ratings do not compromise circuit performance in applications designed for the original 0.667W specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

CRCW2010237RFKEF (Vishay Dale) and RMCF2010FT237R (Stackpole Electronics Inc) are both Active product status alternatives with full electrical and mechanical compatibility. Both parts carry AEC-Q200 automotive qualification, providing additional reliability assurance. The 0.75W power rating offers enhanced thermal margin compared to the original 0.667W specification while maintaining identical package footprint and electrical characteristics.

Secondary Substitute (Legacy Status):

ERJ-12SF2370U (Panasonic Electronic Components) is classified as Not For New Designs. This part meets all electrical and mechanical compatibility requirements and carries AEC-Q200 qualification. Selection of this part is appropriate only for replacement or repair of existing assemblies where design continuity is required.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory equivalence with the original RC5025F2370CS component.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010237RFKEF replace RC5025F2370CS in existing designs?

A: Yes. CRCW2010237RFKEF is electrically and mechanically equivalent. The 0.75W power rating is a superset of the original 0.667W specification and does not introduce compatibility issues. Physical dimensions, package type, and all electrical parameters are identical.

Q: What is the significance of the 0.028" (0.70mm) maximum seated height on substitute parts compared to 0.026" (0.66mm) on the original?

A: The 0.002" (0.04mm) height difference is within typical PCB assembly tolerances and does not affect circuit performance or board-level compatibility. Both dimensions are within standard 2010 package specifications.

Q: Why do substitute parts carry AEC-Q200 automotive qualification while the original does not specify this rating?

A: AEC-Q200 is an automotive industry qualification standard. Substitute parts from Vishay Dale, Panasonic, and Stackpole Electronics Inc include this certification as part of their product qualification. The presence of AEC-Q200 does not restrict use in non-automotive applications and indicates additional quality assurance.

Q: Is ERJ-12SF2370U suitable for new product designs?

A: No. ERJ-12SF2370U carries a "Not For New Designs" product status designation. This part is appropriate for replacement or repair of existing assemblies only. For new designs, select CRCW2010237RFKEF or RMCF2010FT237R, both of which are Active status.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. CRCW2010237RFKEF, ERJ-12SF2370U, and RMCF2010FT237R are all supplied in Tape & Reel packaging. The original RC5025F2370CS is supplied in standard packaging format. Tape & Reel packaging is standard for high-volume SMD component distribution and does not affect component electrical or mechanical properties.

Q: What is the temperature coefficient significance for this resistor family?

A: All parts in this comparison, including the original and substitutes, share an identical temperature coefficient of ±100ppm/°C. This parameter defines the resistance change per degree Celsius across the operating temperature range of -55°C to 155°C. Equivalence in this specification ensures predictable circuit behavior across thermal extremes.
