RC5025F2373CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F2373CS is a 237 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 and operates across the temperature range of -55°C to 155°C. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. The primary substitute listed maintains identical resistance value and tolerance while offering increased power rating and automotive-grade qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F2373CS is determined by the following critical parameters:

Electrical Equivalence Requirements:

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

Mechanical Compatibility Requirements:

• Package format: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Regulatory & Environmental Requirements:

• RoHS3 compliance (minimum requirement)
• Moisture sensitivity level: 1 or better (minimum requirement)

The CRCW2010237KFKEF substitute meets all electrical and mechanical compatibility criteria. The increased power rating (0.75W versus 0.667W) and automotive AEC-Q200 qualification represent enhanced performance characteristics that do not compromise interchangeability in applications designed for the original specification.

Parameter Comparison

Engineering Selection Recommendations

RC5025F2373CS (Samsung Electro-Mechanics):

• Primary selection for applications requiring the specified 0.667W power rating
• Active product status with established supply chain
• ROHS3 compliant with unlimited moisture sensitivity rating
• Suitable for general industrial and consumer applications

CRCW2010237KFKEF (Vishay Dale):

• Direct substitute with enhanced power rating capability (0.75W)
• Automotive AEC-Q200 qualification enables use in automotive and high-reliability applications
• Higher inventory availability supports extended production runs
• Identical electrical performance with improved thermal margin
• ROHS3 compliant with unlimited moisture sensitivity rating

Both parts maintain identical resistance, tolerance, temperature coefficient, and operating temperature specifications. The mechanical footprint and height clearance are compatible for standard PCB assembly processes. Selection between these parts depends on application requirements for automotive qualification and power dissipation margin rather than functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010237KFKEF replace RC5025F2373CS in existing designs?

A: Yes. Both parts share identical electrical specifications (237 kOhms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (2010 package, 5.00mm x 2.50mm footprint). The substitute offers higher power rating (0.75W versus 0.667W) and automotive qualification without compromising interchangeability.

Q: What is the significance of the 0.083W power rating difference?

A: The CRCW2010237KFKEF provides 12.4% additional power dissipation capacity. This represents a performance enhancement that does not affect compatibility. Applications designed for 0.667W operation remain fully functional with the higher-rated substitute.

Q: Are there package compatibility concerns?

A: No. Both parts use the 2010 (5025 Metric) package with identical length and width (5.00mm x 2.50mm). Maximum seated height differs by 0.002" (0.04mm), which is within standard PCB assembly tolerances and does not affect placement or clearance.

Q: What does AEC-Q200 qualification mean for non-automotive applications?

A: AEC-Q200 is an automotive industry standard for passive components. This qualification indicates enhanced reliability testing and quality assurance. Non-automotive applications benefit from this higher qualification level without additional cost or complexity.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC5025F2373CS and CRCW2010237KFKEF carry ROHS3 compliance certification and are REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between tape & reel and standard packaging?

A: CRCW2010237KFKEF is supplied in tape & reel format, which is standard for automated PCB assembly processes. RC5025F2373CS packaging format is not specified in the provided data. Tape & reel packaging does not affect electrical or mechanical performance, only handling and assembly methodology.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range (-55°C to 155°C) with matching temperature coefficients (±100ppm/°C). No derating or performance variation occurs between the two parts across this operating envelope.
