MCR03EZPFX2611 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2611 is a 2.61 kOhms ±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 MCR03EZPFX2611 is determined by strict equivalence across the following parameters:

Resistance value: 2.61 kOhms
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 classified into two categories:

Direct Substitutes maintain full automotive AEC-Q200 certification and identical electrical specifications. These parts are functionally interchangeable without design modification.

Similar Substitutes meet all core electrical and mechanical parameters but feature alternative certifications (moisture resistance instead of automotive rating). These parts are electrically equivalent and mechanically compatible but may require design review for automotive applications.

Engineering Selection Recommendations

For Automotive Applications (AEC-Q200 Required):

Direct substitutes with active product status are ERJ-3EKF2611V (Panasonic), RMCF0603FT2K61 (Stackpole), and CRCW06032K61FKEA (Vishay Dale). All three maintain AEC-Q200 certification and are currently in active production with substantial inventory availability. ERJ-3EKF2611V offers the highest inventory level at 87,282 pieces.

For Non-Automotive Applications:

CR0603-FX-2611ELF (Bourns) and RC0603FR-072K61L (YAGEO) are electrically and mechanically equivalent alternatives. Both are active products with moisture-resistant thick film composition. These parts meet all core electrical parameters but lack automotive certification.

For Discontinued Part Replacement:

MCR03ERTF2611 (Rohm Semiconductor) is a direct Rohm equivalent but is also discontinued. This part should not be selected for new designs requiring long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can I substitute an AEC-Q200 rated part with a non-AEC-Q200 rated part?

A: Substitution depends on application requirements. If your design specifies AEC-Q200 compliance, only parts with this certification (ERJ-3EKF2611V, RMCF0603FT2K61, CRCW06032K61FKEA) are acceptable. Non-certified parts require design review and customer approval.

Q: Are all substitute parts mechanically compatible with the original MCR03EZPFX2611?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical termination count (2) and compatible physical dimensions. Slight variations in height (0.50mm to 0.55mm maximum seated height) are within standard PCB assembly tolerances.

Q: What is the difference between "Direct" and "Similar" substitutes?

A: Direct substitutes maintain AEC-Q200 automotive certification. Similar substitutes meet all electrical and mechanical specifications but feature alternative certifications such as moisture resistance. Both categories are electrically equivalent; the distinction reflects compliance ratings.

Q: Does tolerance or temperature coefficient affect substitutability?

A: No. All listed parts share identical tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). These parameters are fixed across all substitutes.

Q: Which substitute offers the best supply availability?

A: ERJ-3EKF2611V (Panasonic) has the highest inventory at 87,282 pieces and maintains active product status with AEC-Q200 certification.
