MCR03EZPFX1100 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1100 is a 110 Ohms ±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 MCR03EZPFX1100 is determined by strict equivalence across the following parameters: resistance value (110 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and termination count (2). All identified substitutes meet these core electrical and mechanical specifications. Substitutes are grouped into two categories based on automotive certification status: direct equivalents maintain AEC-Q200 automotive qualification, while similar substitutes provide equivalent electrical performance with alternative feature sets (moisture resistance instead of automotive rating).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive qualification under AEC-Q200 standard, direct substitutes CRCW0603110RFKEA (Vishay Dale), ERJ-3EKF1100V (Panasonic Electronic Components), and RMCF0603FT110R (Stackpole Electronics Inc) are recommended. All three maintain active product status with full inventory availability and identical electrical specifications to the original MCR03EZPFX1100.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-1100ELF (Bourns Inc.) and RC0603FR-07110RL (YAGEO) provide equivalent electrical performance with moisture-resistant thick film composition. Both parts maintain active status with adequate inventory levels.

Packaging format selection depends on assembly requirements: Tape & Reel format is available from Vishay Dale, Stackpole Electronics, and Bourns; Cut Tape & Digi-Reel format is available from Panasonic and YAGEO.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-1100ELF or RC0603FR-07110RL as direct replacements for MCR03EZPFX1100 in automotive applications?

A: No. CR0603-FX-1100ELF and RC0603FR-07110RL lack AEC-Q200 automotive certification. Use these only in non-automotive circuits. For automotive applications, select from CRCW0603110RFKEA, ERJ-3EKF1100V, or RMCF0603FT110R.

Q: Are all substitute parts electrically identical to MCR03EZPFX1100?

A: Yes. All listed substitutes match the core electrical parameters: 110 Ohms resistance, ±1% tolerance, 0.1W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel format is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel format is pre-cut tape on a reel for manual or semi-automated handling. Both formats contain identical components; selection depends on assembly equipment compatibility.

Q: Why is the original MCR03EZPFX1100 discontinued?

A: Product discontinuation is determined by manufacturer production decisions. Active substitutes from multiple manufacturers ensure continued availability of equivalent 110 Ohm 0603 resistors with identical specifications.

Q: Can I mix different substitute part numbers in the same production batch?

A: Yes. All listed substitutes meet identical electrical and mechanical specifications. However, verify that your procurement and quality control processes accommodate multiple manufacturer part numbers if required by your supply chain documentation.

Q: What is the physical size difference between substitute parts?

A: All parts use 0603 (1608 Metric) package. Dimensional variations are minimal: length ranges from 1.55mm to 1.60mm, width from 0.80mm to 0.85mm, and height from 0.50mm to 0.55mm. These variations are within standard 0603 package tolerances and do not affect PCB layout or assembly.
