Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCR03EZPFX56R0 are qualified based on the following criteria:

Direct Substitutes maintain identical electrical and mechanical specifications:

• Resistance value: 56 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Composition: Thick Film
• AEC-Q200 automotive qualification
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Similar Substitutes meet all electrical specifications and package requirements but may have minor variations in physical dimensions or additional features (such as moisture resistance enhancements) that do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Preferred Direct Substitutes (AEC-Q200 Qualified):

For applications requiring strict automotive qualification compliance, select from:

• CRCW060356R0FKEA (Vishay Dale) — Active status, AEC-Q200 qualified, Cut Tape packaging
• ERJ-3EKF56R0V (Panasonic Electronic Components) — Active status, AEC-Q200 qualified, highest inventory availability
• RMCF0603FT56R0 (Stackpole Electronics Inc) — Active status, AEC-Q200 qualified

Alternative Substitutes (Non-AEC-Q200):

For applications where automotive qualification is not mandatory:

• AC0603FR-0756RL (YAGEO) — Active status, moisture resistant, AEC-Q200 qualified
• CR0603-FX-56R0ELF (Bourns Inc.) — Active status, moisture resistant
• RC0603FR-0756RL (YAGEO) — Active status, moisture resistant, highest inventory availability (348,359 pcs)

All listed substitutes maintain identical electrical performance (56 Ω ±1%, 0.1W, ±100ppm/°C) and operate across the full temperature range (-55°C ~ 155°C). Selection should prioritize active product status and supply chain availability for long-term production continuity.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-0756RL or CR0603-FX-56R0ELF as direct replacements for MCR03EZPFX56R0?

A: These parts are functionally compatible in terms of electrical performance (56 Ω ±1%, 0.1W, temperature coefficient, and operating range). However, they do not carry AEC-Q200 automotive qualification. Use only if your application does not require automotive-grade certification.

Q: What is the difference between CRCW060356R0FKEA and CRCW060356R0FKEB?

A: Both are Vishay Dale 56 Ω ±1% 0603 resistors with identical electrical specifications and AEC-Q200 qualification. The primary difference is packaging: FKEA uses Cut Tape (CT) & Digi-Reel format, while FKEB uses Tape & Reel (TR) format. FKEB has significantly higher inventory availability (23,724 pcs vs. 1,165 pcs).

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and have MSL rating of 1 (Unlimited), matching the original MCR03EZPFX56R0 specifications.

Q: Which substitute offers the best supply availability?

A: RC0603FR-0756RL (YAGEO) has the highest inventory at 348,359 pcs. For AEC-Q200 qualified alternatives, ERJ-3EKF56R0V (Panasonic) offers 110,404 pcs.

Q: Do physical dimensions vary between substitutes?

A: Minor dimensional variations exist within the 0603 package specification. All parts maintain the same functional footprint for PCB assembly. Verify specific length and height specifications with your assembly process if tight mechanical tolerances are required.
