Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 64.9 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All listed substitute parts meet these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Cut Tape, Digi-Reel, Tape & Reel) do not affect functional equivalence.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from: CRCW060364R9FKEA (Vishay Dale), ERJ-3EKF64R9V (Panasonic Electronic Components), or RMCF0603FT64R9 (Stackpole Electronics Inc). All three are currently in active production status with full AEC-Q200 compliance.

For non-automotive applications where AEC-Q200 qualification is not required, CR0603-FX-64R9ELF (Bourns Inc.) and RC0603FR-0764R9L (YAGEO) are viable alternatives with active product status. RC0603FR-0764R9L offers the highest inventory availability at 301,960 pieces.

MCR03ERTF64R9 (Rohm Semiconductor) is electrically equivalent but lacks AEC-Q200 certification and is discontinued, making it unsuitable for new designs.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX64R9 be directly replaced with any of these substitutes?

A: Yes, all listed parts are electrically and mechanically equivalent. They share identical resistance (64.9 Ω), tolerance (±1%), power rating (0.1W), package (0603), and operating temperature range (-55°C to 155°C). Physical dimension variations are within standard manufacturing tolerances and do not affect circuit performance.

Q: Which substitute is best for automotive applications?

A: CRCW060364R9FKEA, ERJ-3EKF64R9V, and RMCF0603FT64R9 all carry AEC-Q200 certification. Select based on availability and packaging preference (Cut Tape/Digi-Reel vs. Tape & Reel).

Q: Does packaging format affect substitution?

A: No. Packaging format (Cut Tape, Digi-Reel, Tape & Reel) is a supply chain consideration only. All formats contain electrically identical components suitable for the same applications.

Q: Are there differences in temperature coefficient between substitutes?

A: No. All parts specify ±100ppm/°C temperature coefficient, ensuring equivalent thermal performance across the -55°C to 155°C operating range.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture baking requirements, simplifying inventory management and assembly processes for all listed substitutes.
