MCR03EZPFX6041 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX6041 is a 6.04 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 for MCR03EZPFX6041 is determined by strict equivalence across the following parameters:

Resistance value: 6.04 kOhms
Tolerance: ±1%
Power rating: 0.1W (1/10W)
Package: 0603 (1608 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
RoHS3 compliance
MSL rating: 1 (Unlimited)

Substitute parts are classified into two categories:

Direct Substitutes maintain all electrical and mechanical parameters identical to the original part, including automotive AEC-Q200 certification.

Similar Substitutes meet all core electrical and mechanical specifications but differ in specific features (such as moisture resistance designation instead of automotive rating) or packaging format (Cut Tape vs. Tape & Reel).

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications:

CRCW06036K04FKEA (Vishay Dale) is the primary recommended substitute. This part is currently active in production, maintains full AEC-Q200 automotive certification, and is available in high volume (42,131 pcs in stock). Electrical and mechanical parameters are identical to MCR03EZPFX6041.

ERJ-3EKF6041V (Panasonic Electronic Components) and RMCF0603FT6K04 (Stackpole Electronics Inc) are alternative direct substitutes with active product status and AEC-Q200 compliance. Both are suitable for automotive applications requiring equivalent performance.

For Non-Automotive Applications:

CR0603-FX-6041ELF (Bourns Inc.), RC0603FR-076K04L (YAGEO), and RC1608F6041CS (Samsung Electro-Mechanics) meet all electrical and mechanical specifications. These parts lack AEC-Q200 certification but are suitable for general industrial and consumer applications with identical resistance, tolerance, power rating, and temperature characteristics.

Packaging Consideration:

RC1608F6041CS is supplied in Cut Tape (CT) format rather than Tape & Reel (TR). This packaging format may require different handling in automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I use a non-AEC-Q200 rated substitute in an automotive application?

A: No. If the original design specifies AEC-Q200 compliance, only substitutes with AEC-Q200 certification (CRCW06036K04FKEA, CRCW06036K04FKEB, ERJ-3EKF6041V, or RMCF0603FT6K04) are acceptable. Non-automotive rated parts do not meet automotive qualification standards.

Q: What is the difference between Direct and Similar substitutes?

A: Direct substitutes maintain identical electrical parameters and automotive certification. Similar substitutes meet all electrical and mechanical specifications but lack AEC-Q200 automotive rating or use alternative feature designations such as moisture resistance instead of automotive qualification.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats contain identical components. The difference is in supply format and handling during assembly. TR format is standard for high-volume automated assembly; CT format is suitable for lower-volume or manual assembly processes.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), matching the original MCR03EZPFX6041 specifications.

Q: Can I substitute based on resistance value alone?

A: No. Substitution requires equivalence across all parameters: resistance (6.04 kOhms), tolerance (±1%), power rating (0.1W), package (0603), composition (Thick Film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Deviations in any parameter may affect circuit performance or reliability.
