Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 124 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package type: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RMCF2010FT124K from Stackpole Electronics Inc meets all electrical and mechanical parameters. The substitute part maintains identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both parts are Active status and ROHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the RC2010FK-07124KL and RMCF2010FT124K are Active status components with ROHS3 compliance. The RMCF2010FT124K carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The seated height difference of 0.002" (0.05mm) is within typical PCB assembly tolerances and does not affect functional compatibility. Selection between these parts should be based on application requirements, inventory availability, and any specific automotive or reliability certifications mandated by the design specification.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT124K replace RC2010FK-07124KL in existing designs?

A: Yes. Both parts share identical electrical specifications (124 kOhms ±1%, 0.75W), thermal characteristics (±100ppm/°C, -55°C to 155°C), and package dimensions (2010 / 5025 Metric). The maximum seated height difference of 0.002" is negligible for standard PCB assembly.

Q: What is the significance of AEC-Q200 qualification on the RMCF2010FT124K?

A: AEC-Q200 is an automotive industry standard for passive components. This qualification indicates the part has undergone enhanced reliability testing and is suitable for automotive applications. Non-automotive applications are not restricted from using AEC-Q200 qualified parts.

Q: Are there any moisture sensitivity concerns with either part?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations. Standard handling and storage practices apply.

Q: Do both parts meet RoHS requirements?

A: Yes. Both RC2010FK-07124KL and RMCF2010FT124K are ROHS3 compliant and REACH unaffected.

Q: What is the difference in package designation between these parts?

A: Both parts use the 2010 (5025 Metric) package designation. This refers to the same physical footprint: 5.00mm length × 2.50mm width. The parts are mechanically and electrically interchangeable at the PCB level.
