MCR03EZPFX56R2 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX56R2 is a 56.2 Ohm ±1% thick film chip resistor in 0603 (1608 Metric) package rated for 0.1W power dissipation. Manufactured by Rohm Semiconductor, this component meets AEC-Q200 automotive qualification standards and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX56R2 is determined by strict equivalence across the following parameters:

Resistance value: 56.2 Ohms
Tolerance: ±1%
Power rating: 0.1W
Package designation: 0603 (1608 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
RoHS3 compliance
MSL rating: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical specifications. Parts are categorized as Direct Manufacturer equivalents (meeting AEC-Q200 automotive qualification) or Similar alternatives (meeting general industrial specifications with moisture resistance).

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from the Direct Manufacturer equivalents: CRCW060356R2FKEA (Vishay Dale), ERJ-3EKF56R2V (Panasonic Electronic Components), or RMCF0603FT56R2 (Stackpole Electronics Inc). All three maintain active product status with established supply chains.

For non-automotive applications or where moisture resistance is prioritized, CR0603-FX-56R2ELF (Bourns Inc.) and RC0603FR-0756R2L (YAGEO) provide equivalent electrical performance with moisture-resistant thick film construction. Both are actively manufactured with high inventory availability.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications to the discontinued MCR03EZPFX56R2.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-56R2ELF or RC0603FR-0756R2L as direct replacements in automotive applications?

A: CR0603-FX-56R2ELF and RC0603FR-0756R2L are not AEC-Q200 qualified. For automotive applications, use CRCW060356R2FKEA, ERJ-3EKF56R2V, or RMCF0603FT56R2 instead.

Q: Are all substitute parts physically compatible with the original PCB footprint?

A: All parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly within tolerance: length ranges from 1.55mm to 1.60mm, width from 0.80mm to 0.85mm, and height from 0.50mm to 0.55mm. Standard 0603 PCB footprints accommodate these variations.

Q: What is the difference between Direct Manufacturer and Similar substitute classifications?

A: Direct Manufacturer substitutes (CRCW060356R2FKEA, ERJ-3EKF56R2V, RMCF0603FT56R2) meet AEC-Q200 automotive qualification matching the original part. Similar substitutes (CR0603-FX-56R2ELF, RC0603FR-0756R2L) meet equivalent electrical specifications with moisture-resistant construction but lack automotive qualification.

Q: Do all substitute parts have the same moisture sensitivity level?

A: All listed parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute offers the highest inventory availability?

A: RC0603FR-0756R2L (YAGEO) has 229,433 pieces in stock, followed by ERJ-3EKF56R2V (Panasonic) with 110,356 pieces.
