MCR03EZPFX13R3 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX13R3 is a 13.3 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.

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX13R3 is determined by strict equivalence across the following parameters:

Resistance value: 13.3 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
RoHS3 compliance
MSL rating: 1 (Unlimited)

All listed substitute parts meet these core electrical and mechanical specifications. Direct substitutes maintain identical ratings and certifications. The RC0603FR-0713R3L is classified as a similar part due to the absence of AEC-Q200 automotive certification, though it meets all other electrical and mechanical parameters.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive certification, select from CRCW060313R3FKEA (Vishay Dale), ERJ-3EKF13R3V (Panasonic), or RMCF0603FT13R3 (Stackpole Electronics). All three are currently in active production status with full automotive qualification.

CRCW060313R3FKEA offers the highest inventory availability (16130 Pcs) among AEC-Q200 qualified alternatives. ERJ-3EKF13R3V provides the largest stock position overall (48117 Pcs) and maintains active product status. RMCF0603FT13R3 is AEC-Q200 qualified but has lower inventory levels (1478 Pcs).

For non-automotive applications where AEC-Q200 certification is not required, RC0603FR-0713R3L (YAGEO) is available with extensive inventory (32511 Pcs) and active product status. This part meets all electrical and mechanical specifications but lacks automotive qualification.

MCR03ERTF13R3 (Rohm Semiconductor) is a discontinued alternative from the original manufacturer with higher inventory availability (5400 Pcs) but no AEC-Q200 rating.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF13R3 replace MCR03EZPFX13R3 in automotive applications?

A: MCR03ERTF13R3 lacks AEC-Q200 certification. Use only if automotive qualification is not a design requirement. Both parts are discontinued at DiGi Electronics.

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

A: Direct substitutes (CRCW060313R3FKEA, ERJ-3EKF13R3V, RMCF0603FT13R3) maintain AEC-Q200 automotive certification. RC0603FR-0713R3L is classified as similar because it lacks this certification, though electrical and mechanical parameters are identical.

Q: Are all substitute parts in the same 0603 package?

A: Yes. All listed parts use the 0603 (1608 Metric) package with identical footprint compatibility. Physical dimensions vary slightly within tolerance (length 1.55mm to 1.60mm, height 0.50mm to 0.55mm), but all are PCB-compatible within standard 0603 placement specifications.

Q: Which substitute has the best availability?

A: ERJ-3EKF13R3V (Panasonic) has the highest inventory at 48117 Pcs. CRCW060313R3FKEA (Vishay Dale) offers 16130 Pcs with AEC-Q200 certification. RC0603FR-0713R3L (YAGEO) has 32511 Pcs but without automotive qualification.

Q: Do all parts meet RoHS3 compliance?

A: Yes. All listed parts are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: What is the temperature coefficient significance?

A: All parts share ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range, ensuring consistent resistance stability across thermal extremes in automotive environments.
