MCR03EZPFX3570 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX3570 is a 357 Ohms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This automotive-grade thick film resistor meets AEC-Q200 qualification standards and operates across -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 MCR03EZPFX3570 is determined by strict equivalence across the following parameters:

Resistance value: 357 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
RoHS3 compliance
MSL rating: 1 (Unlimited)

Substitute parts are grouped into two categories:

Direct Substitutes maintain full automotive AEC-Q200 qualification and identical electrical/mechanical specifications.

Similar Substitutes meet all core electrical and package requirements but feature alternative certifications (moisture resistance instead of automotive qualification) or minor dimensional variations within acceptable tolerances.

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance:

CRCW0603357RFKEA (Vishay Dale), ERJ-3EKF3570V (Panasonic), and RMCF0603FT357R (Stackpole Electronics) are direct functional equivalents with active product status and full automotive qualification. CRCW0603357RFKEA offers the highest inventory availability (19,674 units) and active production status.

For general-purpose applications without automotive qualification requirements:

CR0603-FX-3570ELF (Bourns) and RC0603FR-07357RL (YAGEO) meet all electrical and package specifications with moisture-resistant thick film construction. RC0603FR-07357RL provides exceptional inventory depth (687,233 units) and active status.

For Rohm Semiconductor continuity:

MCR03ERTF3570 maintains the same manufacturer and series but is also discontinued. This option is suitable only if existing supply chain documentation or design specifications mandate Rohm components.

Frequently Asked Questions (FAQ)

Q: Can I substitute MCR03EZPFX3570 with any of the listed parts?

A: Yes, all listed parts meet the core electrical specifications (357 Ω ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). Selection depends on whether AEC-Q200 automotive qualification is required for your application.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes (CRCW0603357RFKEA, ERJ-3EKF3570V, RMCF0603FT357R) carry AEC-Q200 automotive qualification matching the original part. Similar substitutes (CR0603-FX-3570ELF, RC0603FR-07357RL) feature moisture-resistant construction instead of automotive certification but are electrically and mechanically equivalent.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within acceptable tolerances. CRCW0603357RFKEA measures 1.55mm × 0.85mm with 0.50mm max height; RMCF0603FT357R measures 1.55mm × 0.80mm with 0.022" max height. All others match the original 1.60mm × 0.80mm footprint with 0.55mm max height. These variations are within standard PCB design tolerances for 0603 packages.

Q: Which substitute has the best availability?

A: RC0603FR-07357RL (YAGEO) has the highest inventory at 687,233 units. For AEC-Q200 qualified parts, CRCW0603357RFKEA (Vishay Dale) offers 19,674 units with active production status.

Q: Can I use these substitutes interchangeably on the same PCB?

A: Yes. All parts share identical electrical characteristics, tolerance, power rating, and 0603 package footprint. Footprint compatibility is confirmed across all substitutes for standard 0603 PCB designs.

Q: What compliance certifications apply to all substitutes?

A: All parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). AEC-Q200 automotive qualification applies only to CRCW0603357RFKEA, ERJ-3EKF3570V, and RMCF0603FT357R.
