Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F27R4CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27.4 Ohms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power dissipation capacity than the original 0.667W specification, provided all other parameters remain equivalent.

The CRCW201027R4FKEF from Vishay Dale meets all mandatory matching parameters and provides an increased power rating of 0.75W (3/4W), making it a valid substitute for applications where higher power dissipation capability is beneficial or required.

Parameter Comparison

Engineering Selection Recommendations

RC5025F27R4CS (Samsung Electro-Mechanics): Select this part for applications requiring moisture-resistant thick film construction with standard 2/3W power dissipation. The component is Active status with ROHS3 compliance and unlimited moisture sensitivity rating, suitable for general industrial and consumer applications.

CRCW201027R4FKEF (Vishay Dale): Select this part as a substitute when higher power dissipation capacity (0.75W versus 0.667W) is required or preferred. This component carries AEC-Q200 automotive qualification, indicating enhanced reliability standards. The part maintains identical electrical specifications (27.4 Ohms ±1%, ±100ppm/°C, -55°C to 155°C) and physical package dimensions, with a marginal height increase of 0.002" (0.04mm). ROHS3 compliance and unlimited moisture sensitivity rating are maintained.

Both parts are Active status products with full regulatory compliance (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can CRCW201027R4FKEF replace RC5025F27R4CS in any application?

A: Yes, the CRCW201027R4FKEF is a valid substitute. Both parts share identical resistance (27.4 Ohms), tolerance (±1%), package (2010 / 5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute provides higher power rating (0.75W versus 0.667W), which is compatible with applications designed for the original part.

Q: What is the physical difference between these parts?

A: Both parts have identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). The maximum seated height differs by 0.002" (0.04mm): RC5025F27R4CS is 0.026" (0.66mm), while CRCW201027R4FKEF is 0.028" (0.70mm). This minimal difference is negligible for standard PCB assembly and does not affect component placement or clearance in typical applications.

Q: Are there packaging differences between these parts?

A: The RC5025F27R4CS is supplied in standard packaging, while the CRCW201027R4FKEF is supplied in Tape & Reel (TR) format. Both use identical 2010 (5025 Metric) package / case specifications. Tape & Reel packaging is standard for automated assembly processes and does not affect component electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC5025F27R4CS and CRCW201027R4FKEF are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry unlimited moisture sensitivity rating (MSL 1). The CRCW201027R4FKEF additionally carries AEC-Q200 automotive qualification.

Q: What determines substitution eligibility for 2010 chip resistors?

A: Substitution is determined by matching resistance value, tolerance, power rating (equal or higher), composition, temperature coefficient, operating temperature range, package dimensions, and regulatory compliance status. All electrical and mechanical parameters must align within specified tolerances. Physical package footprint and termination count must be identical.
