RMCF2010FT44K2 Equivalent & Substitute Parts

Part Overview

The RMCF2010FT44K2 is a 44.2 kOhms ±1% 0.75W chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor meets automotive AEC-Q200 qualification and operates across -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility across qualified alternatives is needed while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF2010FT44K2 is determined by strict equivalence across the following parameters:

• Resistance value: 44.2 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Physical dimensions and termination count

The ERJ-12SF4422U from Panasonic Electronic Components meets all electrical and mechanical parameters required for direct substitution. Both parts share identical resistance, tolerance, power rating, package configuration, thermal characteristics, and automotive qualification.

Engineering Selection Recommendations

The RMCF2010FT44K2 maintains active product status with ROHS3 compliance and is the preferred selection for new designs. The ERJ-12SF4422U provides electrical and mechanical equivalence but carries a "Not For New Designs" status and is RoHS non-compliant, making it suitable only for legacy system maintenance or replacement applications where the original part specification must be preserved.

Selection between these parts should be based on design phase requirements: active production designs should specify RMCF2010FT44K2, while field replacements or legacy system support may utilize ERJ-12SF4422U when supply of the primary part is constrained.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF4422U be used as a direct replacement for RMCF2010FT44K2 in new designs?

A: No. While ERJ-12SF4422U is electrically and mechanically equivalent, it carries "Not For New Designs" status and is RoHS non-compliant. New designs must specify RMCF2010FT44K2.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in 2010 (5025 Metric) with identical length (0.197"), width (0.098"), and maximum seated height (0.028"). They are mechanically interchangeable at the PCB level.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RMCF2010FT44K2 and ERJ-12SF4422U carry AEC-Q200 automotive qualification and operate across -55°C to 155°C with ±100ppm/°C temperature coefficient.

Q: What is the difference in compliance status between these parts?

A: RMCF2010FT44K2 is ROHS3 compliant with active product status. ERJ-12SF4422U is RoHS non-compliant and marked "Not For New Designs," indicating end-of-life or legacy status.

Q: Are tolerance and resistance values identical?

A: Yes. Both parts are 44.2 kOhms ±1% with 0.75W power rating and ±100ppm/°C temperature coefficient.
