MCR03EZPFX2200 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2200 is a 220 Ohm ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (220 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1).

Substitute parts are categorized into two groups:

Direct Substitutes meet all electrical and mechanical specifications with AEC-Q200 automotive certification: CRCW0603220RFKEA (Vishay Dale, Active), ERJ-3EKF2200V (Panasonic, Active), and RMCF0603FT220R (Stackpole Electronics, Active).

Similar Substitutes meet all electrical and mechanical specifications but feature moisture-resistant construction without explicit AEC-Q200 designation: CR0603-FX-2200ELF (Bourns), RC0603FR-07220RL (YAGEO), and RC1608F221CS (Samsung Electro-Mechanics). These parts maintain identical resistance, tolerance, power rating, package, temperature coefficient, and operating temperature range.

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from active direct substitutes: ERJ-3EKF2200V (Panasonic) offers the highest inventory availability at 565,384 units; RMCF0603FT220R (Stackpole Electronics) provides 184,444 units; CRCW0603220RFKEA (Vishay Dale) supplies 50,300 units. All three maintain identical electrical specifications and automotive certification.

For non-automotive or general-purpose applications where AEC-Q200 certification is not required, similar substitutes CR0603-FX-2200ELF (Bourns, 89,510 units), RC1608F221CS (Samsung Electro-Mechanics, 89,263 units), and RC0603FR-07220RL (YAGEO, 5,947 units) are functionally equivalent with moisture-resistant construction.

All substitute parts are ROHS3 compliant with MSL 1 rating, matching the original component's environmental and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I use a similar substitute part in place of the MCR03EZPFX2200 in an automotive application?

A: Similar substitute parts (CR0603-FX-2200ELF, RC0603FR-07220RL, RC1608F221CS) lack explicit AEC-Q200 automotive certification. For automotive designs requiring AEC-Q200 compliance, use direct substitutes: ERJ-3EKF2200V, RMCF0603FT220R, or CRCW0603220RFKEA.

Q: Are all substitute parts physically compatible with the original PCB layout?

A: All substitute parts use the 0603 (1608 Metric) package with identical termination count (2). Physical dimensions vary slightly within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm) and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances for 0603 components.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes (CRCW0603220RFKEA, ERJ-3EKF2200V, RMCF0603FT220R) carry AEC-Q200 automotive certification matching the original part. Similar substitutes (CR0603-FX-2200ELF, RC0603FR-07220RL, RC1608F221CS) meet all electrical and mechanical specifications with moisture-resistant construction but without automotive certification.

Q: Do all substitute parts meet RoHS and MSL requirements?

A: All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original MCR03EZPFX2200 environmental and regulatory compliance.

Q: Which substitute offers the best supply availability?

A: ERJ-3EKF2200V (Panasonic Electronic Components) provides the highest inventory at 565,384 units with active product status and AEC-Q200 certification.
