MCR03EZPFX1133 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1133 is a 113 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, necessitating identification of equivalent alternatives that maintain identical electrical and mechanical specifications for seamless board-level substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (113 kOhms), 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 RoHS3 compliance. All identified substitute parts meet these core electrical and mechanical requirements. Parts are categorized as direct substitutes when they maintain full AEC-Q200 automotive qualification, and as similar substitutes when they provide equivalent electrical performance with alternative feature sets (moisture resistance instead of automotive rating).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring strict automotive qualification compliance, direct substitutes CRCW0603113KFKEA (Vishay Dale), ERJ-3EKF1133V (Panasonic Electronic Components), and RMCF0603FT113K (Stackpole Electronics Inc) are preferred selections. All three maintain active product status, full AEC-Q200 certification, and identical electrical specifications to the discontinued MCR03EZPFX1133.

For non-automotive applications or designs where moisture resistance is prioritized over automotive qualification, CR0603-FX-1133ELF (Bourns Inc.) and RC0603FR-07113KL (YAGEO) provide equivalent electrical performance with active availability. RC0603FR-07113KL offers the highest inventory availability among all alternatives.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard PCB assembly processes and long-term storage without moisture baking requirements.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-1133ELF or RC0603FR-07113KL be used in automotive applications? A: These parts do not carry AEC-Q200 certification. They are suitable for non-automotive applications. For automotive designs, use CRCW0603113KFKEA, ERJ-3EKF1133V, or RMCF0603FT113K.

Q: Are all substitute parts physically compatible with the original MCR03EZPFX1133 footprint? A: All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly within standard 0603 tolerances (length 1.55–1.60mm, width 0.80–0.85mm, height 0.50–0.55mm). PCB footprints designed for 0603 accommodate these variations.

Q: What is the difference between direct and similar substitutes? A: Direct substitutes (CRCW0603113KFKEA, ERJ-3EKF1133V, RMCF0603FT113K) maintain full AEC-Q200 automotive qualification. Similar substitutes (CR0603-FX-1133ELF, RC0603FR-07113KL) provide equivalent electrical performance with moisture-resistant features but without automotive certification.

Q: Do all substitutes have the same temperature coefficient? A: All listed substitutes maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, matching the original MCR03EZPFX1133 specification.

Q: Which substitute offers the best inventory availability? A: RC0603FR-07113KL (YAGEO) has the highest inventory level at 1,085,234 pieces. For automotive-qualified alternatives, ERJ-3EKF1133V (Panasonic) offers 100,279 pieces.
