Substitute Part Grouping Explanation

Substitution eligibility for the RMCF2010FT44R2 is determined by strict equivalence across the following parameters:

• Resistance value: 44.2 Ohms
• Tolerance: ±1%
• Power rating: 0.75W
• Package designation: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts maintain these electrical and mechanical specifications. Substitution does not require design modification, PCB layout changes, or requalification of thermal performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

CRCW201044R2FKEF (Vishay Dale) is the primary substitute for new designs. This part maintains active production status and carries identical electrical, mechanical, and compliance specifications. Inventory availability is 9122 units.

ERJ-12SF44R2U (Panasonic Electronic Components) is functionally equivalent but carries a "Not For New Designs" status. This designation indicates the manufacturer is phasing out this product line. Use of this part is acceptable for legacy system maintenance or existing design revisions where supply continuity is required, but it is not recommended for new product development.

Both substitute parts are ROHS3 compliant, AEC-Q200 rated, and maintain identical thermal and electrical performance characteristics as the primary RMCF2010FT44R2 component.

Frequently Asked Questions (FAQ)

Q: Can CRCW201044R2FKEF be used as a direct replacement for RMCF2010FT44R2 without PCB modification?

A: Yes. Both parts share identical package dimensions (2010/5025 Metric), termination count (2), and footprint specifications. No PCB layout changes are required.

Q: What is the significance of the "Not For New Designs" status on ERJ-12SF44R2U?

A: This designation indicates Panasonic has discontinued active development of this product line. While the part remains functionally equivalent and available in inventory (9171 units), it should not be selected for new product designs due to uncertain long-term availability and potential future discontinuation.

Q: Are all three parts suitable for automotive applications?

A: Yes. RMCF2010FT44R2, CRCW201044R2FKEF, and ERJ-12SF44R2U all carry AEC-Q200 automotive qualification and are rated for the same operating temperature range (-55°C to 155°C).

Q: Do these parts require different soldering profiles or handling procedures?

A: No. All three parts share identical MSL 1 (Unlimited) moisture sensitivity ratings and are supplied in Tape & Reel packaging. Standard SMD assembly processes apply uniformly across all three components.

Q: What is the basis for substitution between these three parts?

A: Substitution is based on exact equivalence of resistance value (44.2 Ohms), tolerance (±1%), power rating (0.75W), package type (2010), composition (Thick Film), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and automotive compliance (AEC-Q200). All mechanical dimensions and electrical performance characteristics are identical.
