Substitute Part Grouping Explanation

Substitution of the RC5025F512CS is permissible with the RC2010FK-075K1L based on the following criteria:

Matching Parameters:

• Resistance value: 5.1 kOhms (identical)
• Tolerance: ±1% (identical)
• Package / Case: 2010 (5025 Metric) (identical)
• Composition: Thick Film (identical)
• Temperature Coefficient: ±100ppm/°C (identical)
• Operating Temperature Range: -55°C ~ 155°C (identical)
• Moisture Resistance: Yes (identical)
• RoHS Status: ROHS3 Compliant (identical)
• MSL Rating: 1 (Unlimited) (identical)

Differing Parameter:

• Power Rating: RC5025F512CS rated at 0.667W (2/3W); RC2010FK-075K1L rated at 0.75W (3/4W)

The substitute part provides equal or superior electrical performance in all critical parameters. The increased power rating of the substitute part does not restrict its use in applications designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-075K1L manufactured by YAGEO is a direct substitute for the RC5025F512CS. Both components maintain identical electrical specifications for resistance, tolerance, temperature coefficient, and operating temperature range. Both components are Active product status and carry equivalent regulatory compliance certifications (RoHS3, REACH Unaffected).

The substitute part features a higher power rating (0.75W versus 0.667W), which provides additional thermal margin in applications without introducing incompatibility. Physical dimensions and package footprint are equivalent, ensuring PCB layout compatibility. Moisture sensitivity levels are identical at MSL 1, indicating no additional handling or storage requirements.

Selection between these parts is determined by availability, lead time, and procurement requirements rather than technical performance constraints.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-075K1L replace RC5025F512CS in existing designs?

A: Yes. The substitute part maintains identical resistance value, tolerance, temperature coefficient, operating temperature range, and package dimensions. The increased power rating does not create incompatibility with circuits designed for the original component.

Q: Are there differences in physical dimensions between these parts?

A: Both parts use the 2010 (5025 Metric) package with identical length and width dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height differs by 0.01mm (0.66mm versus 0.65mm), which is negligible for PCB assembly and clearance considerations.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both RC5025F512CS and RC2010FK-075K1L are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. No additional compliance verification is required for substitution.

Q: What is the significance of the higher power rating on the substitute part?

A: The RC2010FK-075K1L is rated for 0.75W compared to the original 0.667W rating. This higher rating provides additional thermal headroom and does not restrict use in applications designed for the lower-rated original component. The substitute part will operate within specification in all circuits where the original part was specified.

Q: Are packaging formats different between these parts?

A: The RC5025F512CS is supplied in standard packaging format. The RC2010FK-075K1L is supplied in Tape & Reel (TR) format. Both formats are compatible with standard PCB assembly processes. Format selection depends on production volume and assembly equipment requirements.

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

A: Both parts are Active product status with identical temperature coefficients (±100ppm/°C) and operating temperature ranges (-55°C ~ 155°C). Interchangeability is determined by application-specific reliability requirements and qualification procedures rather than inherent part differences.
