Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX22R0 is determined by strict equivalence across the following critical parameters:
- Resistance value: 22 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)
Parts are classified into two categories:
Direct Equivalents maintain full AEC-Q200 automotive certification with identical dimensional specifications.
Similar Alternatives meet all electrical and mechanical parameters but feature moisture-resistant construction instead of automotive AEC-Q200 rating, suitable for applications where automotive qualification is not mandatory.

Engineering Selection Recommendations
For Automotive Applications (AEC-Q200 Required):
CRCW060322R0FKEA (Vishay Dale), ERJ-3EKF22R0V (Panasonic), and RMCF0603FT22R0 (Stackpole Electronics) are direct equivalents with full AEC-Q200 automotive certification. All three maintain identical electrical specifications, temperature performance, and RoHS3 compliance. Selection among these three is based on availability and supply chain requirements. CRCW060322R0FKEA offers the highest inventory availability (100,200 pcs), while ERJ-3EKF22R0V (266,022 pcs) and RMCF0603FT22R0 (311,005 pcs) provide additional sourcing options.
For Non-Automotive Applications:
CR0603-FX-22R0ELF (Bourns) and RC0603FR-0722RL (YAGEO) are suitable alternatives where AEC-Q200 certification is not required. These parts meet all electrical and mechanical parameters with moisture-resistant construction. RC0603FR-0722RL has lower inventory (6,242 pcs) compared to CR0603-FX-22R0ELF (95,270 pcs).
All substitute parts are active products with confirmed RoHS3 compliance and MSL rating 1, ensuring long-term availability and environmental regulatory compliance.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-22R0ELF or RC0603FR-0722RL in an automotive application originally designed for MCR03EZPFX22R0?
A: No. These parts lack AEC-Q200 automotive certification. Use only CRCW060322R0FKEA, ERJ-3EKF22R0V, or RMCF0603FT22R0 for automotive applications requiring AEC-Q200 qualification.
Q: Are all substitute parts pin-compatible with the original MCR03EZPFX22R0?
A: Yes. All listed substitutes use the 0603 (1608 Metric) package with 2 terminations, ensuring mechanical and electrical compatibility on PCB layouts designed for the original part.
Q: What is the difference between direct equivalents and similar alternatives?
A: Direct equivalents (CRCW060322R0FKEA, ERJ-3EKF22R0V, RMCF0603FT22R0) carry AEC-Q200 automotive certification identical to the original part. Similar alternatives (CR0603-FX-22R0ELF, RC0603FR-0722RL) meet all electrical and mechanical specifications but feature moisture-resistant construction without automotive qualification.
Q: Do all substitute parts meet the same temperature coefficient specification?
A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, matching the original MCR03EZPFX22R0 specification.
Q: Which substitute offers the best availability?
A: RMCF0603FT22R0 (Stackpole Electronics) has the highest inventory at 311,005 pcs, followed by ERJ-3EKF22R0V (Panasonic) at 266,022 pcs and CRCW060322R0FKEA (Vishay Dale) at 100,200 pcs.
