Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX8660 is determined by strict equivalence across the following parameters:

• Resistance value: 866 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
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 0603 package specification and differences in packaging format (Cut Tape, Tape & Reel) do not affect functional equivalence.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from the following active parts:

• CRCW0603866RFKEA (Vishay Dale): AEC-Q200 rated, active product status, highest inventory availability (19,426 pcs)
• ERJ-3EKF8660V (Panasonic Electronic Components): AEC-Q200 rated, active product status, highest inventory level (45,408 pcs)
• RMCF0603FT866R (Stackpole Electronics Inc): AEC-Q200 rated, active product status, largest inventory stock (131,576 pcs)

For applications where AEC-Q200 certification is not required, active alternatives include CR0603-FX-8660ELF (Bourns Inc., 50,086 pcs) and RC0603FR-07866RL (YAGEO, 241,653 pcs).

The MCR03ERTF8660 (Rohm Semiconductor) is electrically equivalent but discontinued, making it unsuitable for new procurement.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX8660 be replaced with any of the listed substitutes?

A: Yes, all listed parts are electrically and mechanically equivalent. They share identical resistance (866 Ohms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).

Q: What is the difference between AEC-Q200 rated and non-rated substitutes?

A: AEC-Q200 rated parts (CRCW0603866RFKEA, ERJ-3EKF8660V, RMCF0603FT866R) meet automotive qualification standards. Non-rated parts (CR0603-FX-8660ELF, RC0603FR-07866RL) are suitable for general industrial applications but lack automotive certification.

Q: Does packaging format affect compatibility?

A: No. Packaging format differences (Cut Tape, Tape & Reel, Digi-Reel) do not affect electrical or mechanical compatibility. Selection should be based on procurement and assembly requirements.

Q: Are there dimensional differences between substitutes?

A: Minor variations exist within the 0603 package specification. All parts maintain the same functional footprint and are compatible with standard 0603 PCB layouts.

Q: Which substitute has the best availability?

A: RMCF0603FT866R (Stackpole Electronics Inc) has the largest inventory stock at 131,576 pcs, followed by RC0603FR-07866RL (YAGEO) at 241,653 pcs.
