MCR03EZPFX8061 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX8061 is an 8.06 kOhms ±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 eligibility for the MCR03EZPFX8061 is determined by strict equivalence across the following parameters: resistance value (8.06 kOhms), tolerance (±1%), power rating (0.1W), package type (0603/1608 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All identified substitutes maintain these core electrical and mechanical specifications.

Substitute parts are categorized as follows:

Direct Substitutes (Automotive AEC-Q200 rated): CRCW06038K06FKEA (Vishay Dale), ERJ-3EKF8061V (Panasonic Electronic Components), and RMCF0603FT8K06 (Stackpole Electronics Inc). These parts maintain full automotive qualification and identical parameter specifications.

Similar Substitutes (Moisture Resistant, non-automotive rated): CR0603-FX-8061ELF (Bourns Inc.), RC0603FR-078K06L (YAGEO), and RC1608F8061CS (Samsung Electro-Mechanics). These parts meet all electrical and mechanical parameters but feature moisture-resistant construction instead of automotive AEC-Q200 certification.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 compliance, select from the direct substitute group: CRCW06038K06FKEA, ERJ-3EKF8061V, or RMCF0603FT8K06. All three maintain full automotive qualification and are currently in active production status with established supply availability.

For non-automotive applications where moisture-resistant construction is acceptable, the similar substitute group (CR0603-FX-8061ELF, RC0603FR-078K06L, RC1608F8061CS) provides equivalent electrical performance with active product status and robust inventory levels.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I use a non-automotive rated substitute in an automotive application? A: No. Applications requiring AEC-Q200 certification must use parts from the direct substitute group (CRCW06038K06FKEA, ERJ-3EKF8061V, RMCF0603FT8K06). Non-automotive rated substitutes do not meet automotive qualification requirements.

Q: Are all substitute parts physically identical to the MCR03EZPFX8061? A: All substitutes use the 0603 (1608 Metric) package with identical electrical specifications. Minor dimensional variations exist within tolerance (height range 0.020" to 0.022", length range 0.061" to 0.063"), but these do not affect PCB assembly compatibility.

Q: What is the difference between direct and similar substitutes? A: Direct substitutes carry AEC-Q200 automotive certification matching the original part. Similar substitutes feature moisture-resistant construction instead of automotive rating but maintain all core electrical parameters and operating specifications.

Q: Are all substitutes RoHS compliant? A: Yes. All listed substitutes are ROHS3 compliant with MSL Level 1 rating, meeting standard environmental and handling requirements.

Q: Which substitute has the highest inventory availability? A: ERJ-3EKF8061V (Panasonic Electronic Components) has 211,782 pieces in stock, followed by RC0603FR-078K06L (YAGEO) with 353,696 pieces. Both provide reliable long-term supply.
