MCR03EZPFX1020 Equivalent & Substitute Parts
Part Overview
The MCR03EZPFX1020 is a 102 Ohms ±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 equivalent alternatives that maintain identical electrical and mechanical specifications for seamless circuit board integration.

Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX1020 is determined by strict equivalence across the following parameters: resistance value (102 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 RoHS3 compliance. Parts are classified into two categories:
Direct Substitutes maintain full AEC-Q200 automotive qualification: CRCW0603102RFKEA (Vishay Dale), ERJ-3EKF1020V (Panasonic Electronic Components), and RMCF0603FT102R (Stackpole Electronics Inc).
Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant construction instead of automotive AEC-Q200 rating: CR0603-FX-1020ELF (Bourns Inc.) and RC0603FR-07102RL (YAGEO).

Engineering Selection Recommendations
For applications requiring strict automotive AEC-Q200 compliance, select from the direct substitutes: CRCW0603102RFKEA, ERJ-3EKF1020V, or RMCF0603FT102R. All three maintain active product status with established supply chains and full automotive qualification parity to the original MCR03EZPFX1020.
For non-automotive applications or where moisture-resistant construction is acceptable, CR0603-FX-1020ELF and RC0603FR-07102RL provide equivalent electrical performance with active availability. YAGEO RC0603FR-07102RL offers the highest inventory level (157,224 pcs) among all alternatives.
All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard PCB assembly processes and long-term storage without moisture baking requirements.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-1020ELF or RC0603FR-07102RL as direct replacements for MCR03EZPFX1020 in automotive circuits?
A: These parts meet all electrical and mechanical specifications but lack AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive qualification is not a design requirement.
Q: Are all substitute parts compatible with the same PCB footprint?
A: Yes. All parts use the 0603 (1608 Metric) package with identical termination count (2) and compatible physical dimensions. PCB layout modifications are not required.
Q: What is the difference between direct and similar substitutes?
A: Direct substitutes (CRCW0603102RFKEA, ERJ-3EKF1020V, RMCF0603FT102R) carry AEC-Q200 automotive qualification matching the original part. Similar substitutes (CR0603-FX-1020ELF, RC0603FR-07102RL) feature moisture-resistant construction and are suitable for general industrial applications.
Q: Do all alternatives meet RoHS3 compliance?
A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 moisture sensitivity rating.
Q: Which substitute offers the best availability?
A: RC0603FR-07102RL (YAGEO) has the highest inventory level at 157,224 pcs. For automotive-qualified alternatives, CRCW0603102RFKEA (Vishay Dale) provides 26,366 pcs in stock.
