MCR03EZPFX10R2 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX10R2 is a 10.2 Ohms ±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 to maintain design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX10R2 is determined by strict equivalence across the following parameters:

• Resistance value: 10.2 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. Substitutes are categorized as direct equivalents when they maintain AEC-Q200 automotive qualification, and as compatible alternatives when they meet the base electrical parameters but differ in specific certifications or features.

Parameter Comparison

Engineering Selection Recommendations

Direct substitutes with AEC-Q200 automotive qualification are CRCW060310R2FKEA (Vishay Dale), ERJ-3EKF10R2V (Panasonic Electronic Components), and RMCF0603FT10R2 (Stackpole Electronics Inc). All three maintain identical electrical specifications, operating temperature range, and automotive compliance ratings. Selection among these three should prioritize availability and supply chain logistics.

RC0603FR-0710R2L (YAGEO) is a compatible alternative that meets all core electrical and mechanical parameters with ROHS3 compliance and MSL 1 rating. This part differs in that it carries moisture-resistant classification rather than AEC-Q200 automotive qualification. Use of this part is appropriate for non-automotive applications or where automotive qualification is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-0710R2L replace MCR03EZPFX10R2 in automotive applications?

A: RC0603FR-0710R2L does not carry AEC-Q200 automotive qualification. For automotive designs requiring AEC-Q200 compliance, use CRCW060310R2FKEA, ERJ-3EKF10R2V, or RMCF0603FT10R2 instead.

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

A: All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly within tolerance: length ranges from 0.061" to 0.063" and height from 0.020" to 0.022". Standard 0603 PCB footprints accommodate these variations.

Q: What is the primary reason for substitution?

A: MCR03EZPFX10R2 is discontinued at DiGi Electronics. CRCW060310R2FKEA, ERJ-3EKF10R2V, and RMCF0603FT10R2 are active products with equivalent specifications and higher inventory availability.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.

Q: Which substitute offers the best supply availability?

A: RC0603FR-0710R2L has the highest inventory at 60721 pieces. Among AEC-Q200 qualified alternatives, ERJ-3EKF10R2V offers 31968 pieces and CRCW060310R2FKEA offers 22562 pieces.
