MCR03EZPFX6190 Equivalent & Substitute Parts
Part Overview
The MCR03EZPFX6190 is a 619 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, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation
Substitution for the MCR03EZPFX6190 is determined by strict equivalence across the following parameters: resistance value (619 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core electrical and mechanical specifications.
Substitute parts are grouped into two categories:
Direct Substitutes maintain full automotive AEC-Q200 certification and identical specifications to the original part. These include MCR03ERTF6190 (Rohm Semiconductor), CRCW0603619RFKEA (Vishay Dale), ERJ-3EKF6190V (Panasonic Electronic Components), and RMCF0603FT619R (Stackpole Electronics Inc).
Similar Substitutes meet all core electrical and mechanical parameters but differ in secondary features. CR0603-FX-6190ELF (Bourns Inc.) and RC0603FR-07619RL (YAGEO) feature moisture-resistant construction instead of automotive AEC-Q200 certification, while maintaining identical resistance, tolerance, power rating, package, and temperature specifications.

Engineering Selection Recommendations
For applications requiring automotive AEC-Q200 compliance, select from active-status direct substitutes: CRCW0603619RFKEA (Vishay Dale), ERJ-3EKF6190V (Panasonic Electronic Components), or RMCF0603FT619R (Stackpole Electronics Inc). These parts maintain full certification equivalence with the original MCR03EZPFX6190 and offer current production availability.
For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-6190ELF (Bourns Inc.) and RC0603FR-07619RL (YAGEO) provide functionally equivalent alternatives with active product status and higher inventory availability.
MCR03ERTF6190 (Rohm Semiconductor) is a direct electrical equivalent but lacks AEC-Q200 certification and is discontinued, making it unsuitable for new designs requiring automotive qualification.
Frequently Asked Questions (FAQ)
Q: Can I substitute MCR03EZPFX6190 with any of the listed parts?
A: Substitution depends on application requirements. All listed parts share identical electrical specifications (619 Ω, ±1%, 0.1W, 0603 package). For automotive applications requiring AEC-Q200 certification, use CRCW0603619RFKEA, ERJ-3EKF6190V, or RMCF0603FT619R. For non-automotive applications, CR0603-FX-6190ELF and RC0603FR-07619RL are acceptable.
Q: What is the difference between direct and similar substitutes?
A: Direct substitutes maintain AEC-Q200 automotive certification identical to the original part. Similar substitutes meet all core electrical and mechanical parameters but feature moisture-resistant construction instead of automotive qualification. Selection depends on whether your application requires automotive compliance.
Q: Are all substitute parts in the same 0603 package?
A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical footprint compatibility. Physical dimensions and termination count are equivalent across all listed parts.
Q: Which substitute has the best availability?
A: ERJ-3EKF6190V (Panasonic) and CRCW0603619RFKEA (Vishay Dale) show the highest inventory levels (78,828 and 32,007 pieces respectively) with active product status.
Q: Do all substitutes meet RoHS3 compliance?
A: Yes. All listed parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original MCR03EZPFX6190 specifications.
