Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F41R2CS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance value: 41.2 Ohms
• Tolerance: ±1%
• Package footprint: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Power rating may exceed the original specification (0.667W minimum required)
• Physical height may vary within package specification limits
• Packaging format (bulk vs. Tape & Reel) does not affect electrical substitution

The RMCF2010FT41R2 meets all critical parameters with a higher power rating of 0.75W (3/4W), making it a valid substitute for applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

The RMCF2010FT41R2 is a valid substitute for the RC5025F41R2CS based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical resistance (41.2 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part's higher power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance.

Mechanical Compatibility: Both components utilize the 2010 (5025 Metric) package with identical footprint dimensions (5.00mm x 2.50mm). The height difference (0.70mm vs. 0.66mm) remains within standard package tolerances and does not impact PCB assembly or clearance requirements.

Regulatory Compliance: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). The substitute part includes AEC-Q200 automotive qualification, which provides additional reliability assurance for general-purpose applications.

Product Status: Both parts maintain Active product status with established supply chains. The substitute part has higher inventory availability (6435 pieces vs. 945 pieces).

Frequently Asked Questions (FAQ)

Q: Can the RMCF2010FT41R2 be used as a direct replacement for the RC5025F41R2CS?

A: Yes. Both parts share identical electrical specifications (41.2 Ohms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical footprint (2010 package, 5.00mm x 2.50mm). The substitute part's higher power rating (0.75W) is compatible with applications designed for the original 0.667W specification.

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

A: The RMCF2010FT41R2 is rated at 0.75W compared to the RC5025F41R2CS at 0.667W. This higher rating indicates greater thermal dissipation capability. In applications where the original part is specified, the substitute will operate at lower junction temperatures, improving reliability margins.

Q: Are there any height clearance concerns?

A: The seated height difference is 0.04mm (0.70mm vs. 0.66mm). This variation falls within standard 2010 package tolerances and does not create clearance issues for standard PCB assembly processes or component placement.

Q: Does the AEC-Q200 qualification on the substitute part affect compatibility?

A: No. AEC-Q200 is an automotive qualification standard that indicates additional reliability testing. Its presence on the substitute part does not restrict use in non-automotive applications and provides equivalent or superior performance characteristics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RC5025F41R2CS and RMCF2010FT41R2 are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity), meeting current environmental and regulatory requirements.

Q: What packaging formats are available?

A: The RC5025F41R2CS is supplied in standard packaging format. The RMCF2010FT41R2 is available in Tape & Reel (TR) format, which is standard for high-volume production environments and does not affect electrical or mechanical compatibility.
