MCR03EZPFX57R6 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX57R6 is a 57.6 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 eligibility for the MCR03EZPFX57R6 is determined by strict equivalence across the following critical parameters:

Resistance value: 57.6 Ohms
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
Termination count: 2
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. Automotive AEC-Q200 certification is present on the main part and most substitutes, though this is not a mandatory substitution criterion for non-automotive applications. The YAGEO RC0603FR-0757R6L variant includes moisture-resistant features but maintains full electrical and thermal equivalence.

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from CRCW060357R6FKEA (Vishay Dale), ERJ-3EKF57R6V (Panasonic), or RMCF0603FT57R6 (Stackpole Electronics). All three are currently in active production status with substantial inventory availability.

For non-automotive applications where AEC-Q200 certification is not required, RC0603FR-0757R6L (YAGEO) provides an active, in-stock alternative with moisture-resistant characteristics while maintaining full electrical equivalence.

MCR03ERTF57R6 (Rohm Semiconductor) is also electrically equivalent but shares discontinued status with the original part, limiting its practical utility for new sourcing.

Frequently Asked Questions (FAQ)

Q: Can I substitute MCR03EZPFX57R6 with any of the listed parts?

A: Yes, all listed parts are electrically and mechanically equivalent. Selection depends on application requirements (automotive vs. non-automotive) and product availability. For automotive applications, prioritize parts with AEC-Q200 certification.

Q: What is the difference between the Rohm MCR03ERTF57R6 and MCR03EZPFX57R6?

A: Both are 57.6 Ohms ±1% 0.1W 0603 resistors from Rohm Semiconductor with identical electrical specifications. The MCR03EZPFX57R6 includes AEC-Q200 automotive certification; the MCR03ERTF57R6 does not. Both are discontinued.

Q: Is the YAGEO RC0603FR-0757R6L suitable for automotive applications?

A: The RC0603FR-0757R6L lacks AEC-Q200 certification. For automotive applications, use CRCW060357R6FKEA, ERJ-3EKF57R6V, or RMCF0603FT57R6 instead.

Q: Are there physical dimension differences between substitutes?

A: Minor variations exist within tolerance. The CRCW060357R6FKEA measures 0.061" L x 0.033" W with 0.020" max height. The MCR03EZPFX57R6, MCR03ERTF57R6, ERJ-3EKF57R6V, and RC0603FR-0757R6L measure 0.063" L x 0.031" W with 0.022" max height. The RMCF0603FT57R6 measures 0.061" L x 0.031" W with 0.022" max height. All fit standard 0603 footprints.

Q: Which substitute has the highest inventory availability?

A: ERJ-3EKF57R6V (Panasonic) has 52,258 pieces in stock, followed by CRCW060357R6FKEA (Vishay Dale) with 20,689 pieces.

Q: Do all substitutes have the same moisture sensitivity rating?

A: Yes, all parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity concerns for storage and handling.
