MCR03EZPFX48R7 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX48R7 is a 48.7 Ohm ±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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX48R7 is determined by strict equivalence across the following critical parameters:

• Resistance value: 48.7 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 to 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 direct substitutes, though this is not a mandatory substitution criterion for non-automotive applications. The YAGEO RC0603FR-0748R7L is classified as a similar part due to its moisture-resistant feature rather than automotive certification, but maintains full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 certification, the CRCW060348R7FKEA (Vishay Dale), ERJ-3EKF48R7V (Panasonic), and RMCF0603FT48R7 (Stackpole) are qualified direct substitutes. All three are currently in active production status with substantial inventory availability.

For non-automotive applications where AEC-Q200 certification is not required, the RC0603FR-0748R7L (YAGEO) provides an electrically and mechanically equivalent alternative with the highest inventory availability (265,648 pieces).

The MCR03ERTF48R7 (Rohm Semiconductor) is also discontinued and therefore not recommended for new designs despite electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can I use CRCW060348R7FKEA as a direct replacement for MCR03EZPFX48R7?

A: Yes. Both parts share identical electrical specifications (48.7 Ω ±1%, 0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Both carry AEC-Q200 automotive certification. The CRCW060348R7FKEA is in active production with higher inventory availability.

Q: What is the difference between the direct substitutes and the YAGEO RC0603FR-0748R7L?

A: The RC0603FR-0748R7L is classified as a similar part rather than a direct substitute because it features moisture-resistant composition instead of automotive AEC-Q200 certification. Electrically and mechanically, it is fully equivalent. Use this part for non-automotive applications or where moisture resistance is specifically required.

Q: Are there any dimensional differences between these substitutes?

A: Minor dimensional variations exist within tolerance. The CRCW060348R7FKEA and RMCF0603FT48R7 have slightly different length and height specifications compared to the original MCR03EZPFX48R7, but all remain within 0603 package specifications and are PCB-compatible.

Q: Can I mix different manufacturers' parts in the same circuit board?

A: Yes. All listed substitutes meet identical electrical and mechanical specifications. Mixed sourcing is acceptable from a functional standpoint, though design documentation should reflect the approved part list.

Q: Which substitute has the best availability?

A: The YAGEO RC0603FR-0748R7L has the highest inventory (265,648 pieces). Among AEC-Q200 certified alternatives, the ERJ-3EKF48R7V (Panasonic) has the largest stock (57,715 pieces).
