Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC5025F270CS is permissible with the RC2010FK-0727RL based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Resistance value: 27 Ohms (identical)
• Tolerance: ±1% (identical)
• Package format: 2010 (5025 Metric) (identical)
• Physical dimensions: 0.197" L x 0.098" W / 5.00mm x 2.50mm (identical)
• Composition: Thick Film (identical)
• Temperature Coefficient: ±100ppm/°C (identical)
• Operating Temperature Range: -55°C ~ 155°C (identical)
• Moisture Resistance: Yes (identical)
• RoHS3 Compliance: Yes (identical)
• MSL Rating: 1 (Unlimited) (identical)
• Number of Terminations: 2 (identical)

Distinguishing Parameter:

• Power Rating: RC2010FK-0727RL is rated at 0.75W (3/4W), which exceeds the 0.667W (2/3W) rating of the RC5025F270CS

The RC2010FK-0727RL substitute provides enhanced power dissipation capability while maintaining all other electrical and mechanical specifications, making it suitable for direct replacement in applications where the original part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the RC5025F270CS and RC2010FK-0727RL are Active product status components with full RoHS3 compliance and REACH Unaffected designation, confirming regulatory alignment for industrial and commercial applications.

The RC2010FK-0727RL substitute is electrically and mechanically compatible with the RC5025F270CS across all specified parameters. The elevated power rating of 0.75W (3/4W) on the substitute part provides additional thermal margin compared to the original 0.667W (2/3W) specification. This enhanced rating does not introduce incompatibility and supports applications requiring higher power dissipation within the same package footprint.

Selection between these parts should be based on availability, supply chain requirements, and application-specific power dissipation demands. Both components maintain identical resistance, tolerance, temperature coefficient, operating temperature range, and moisture resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the RC2010FK-0727RL replace the RC5025F270CS in all applications?

A: Yes. The RC2010FK-0727RL is electrically and mechanically compatible with the RC5025F270CS. All critical parameters including resistance value, tolerance, temperature coefficient, operating temperature range, package dimensions, and compliance certifications are identical. The higher power rating of the substitute part (0.75W vs. 0.667W) does not create incompatibility.

Q: What is the significance of the different power ratings?

A: The RC2010FK-0727RL is rated for 0.75W (3/4W) continuous power dissipation, while the RC5025F270CS is rated for 0.667W (2/3W). The substitute part provides greater thermal capacity. In applications where the original part operates near its power limit, the substitute offers additional margin. In applications where power dissipation is well below the original rating, both parts perform identically.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2010 (5025 Metric) package format with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height is 0.026" (0.66mm for the original, 0.65mm for the substitute), representing negligible difference. Both parts are mechanically interchangeable on PCB layouts designed for the 2010 package.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RC5025F270CS and RC2010FK-0727RL are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both parts satisfy identical regulatory and environmental compliance requirements.

Q: What is the temperature coefficient specification and why does it matter?

A: Both parts specify ±100ppm/°C temperature coefficient across the operating range of -55°C to 155°C. This parameter defines the resistance change per degree Celsius. Identical temperature coefficients ensure predictable performance across thermal cycling and temperature extremes in both parts.

Q: Are there packaging differences between these parts?

A: The RC5025F270CS is supplied in standard packaging format. The RC2010FK-0727RL is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume manufacturing and automated assembly processes. Both packaging formats contain identical components; the difference is in the delivery and handling method.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The RC2010FK-0727RL is a direct substitute for the RC5025F270CS. No design modifications, PCB layout changes, or circuit adjustments are required. The parts are pin-compatible, dimensionally identical, and electrically equivalent across all specified parameters.
