MCR03EZPFX3013 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX3013 is a 301 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 functionally equivalent alternatives from active manufacturers to maintain design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (301 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 compliance certifications (RoHS3, MSL 1).

Substitute parts are categorized into two groups:

Direct Substitutes maintain full AEC-Q200 automotive qualification: CRCW0603301KFKEA, CRCW0603301KFKEB, ERJ-3EKF3013V, and RMCF0603FT301K. These parts are electrically and mechanically interchangeable with the original MCR03EZPFX3013.

Similar Substitutes meet all electrical and mechanical specifications but feature moisture-resistant composition instead of automotive AEC-Q200 rating: CR0603-FX-3013ELF (Bourns) and RC0603FR-07301KL (YAGEO). These are suitable for applications where automotive qualification is not mandatory.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 compliance, select from active direct substitutes: ERJ-3EKF3013V (Panasonic) with 67636 units in stock, or RMCF0603FT301K (Stackpole) with 3279 units. CRCW0603301KFKEA (Vishay Dale) is also active with 14714 units available.

For non-automotive applications where AEC-Q200 certification is not required, CR0603FR-07301KL (YAGEO) offers the highest inventory availability at 314913 units, followed by CR0603-FX-3013ELF (Bourns) with 44474 units.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications (301 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C operating range).

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-3013ELF or RC0603FR-07301KL as direct replacements for MCR03EZPFX3013 in automotive applications?

A: No. These parts lack AEC-Q200 automotive qualification. Use them only in non-automotive designs. For automotive applications, select from ERJ-3EKF3013V, RMCF0603FT301K, CRCW0603301KFKEA, or CRCW0603301KFKEB.

Q: Are all substitute parts mechanically compatible with the 0603 package footprint?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical termination count (2) and compatible physical dimensions within standard PCB assembly tolerances.

Q: What is the difference between CRCW0603301KFKEA and CRCW0603301KFKEB?

A: Both are Vishay Dale CRCW series 301 kOhms ±1% 0.1W 0603 resistors with identical electrical specifications. CRCW0603301KFKEA is currently active with 14714 units in stock, while CRCW0603301KFKEB is discontinued with 9825 units remaining.

Q: Do all substitute parts meet RoHS3 and MSL 1 requirements?

A: Yes. All listed direct and similar substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original MCR03EZPFX3013 specifications.

Q: Which substitute offers the best supply availability?

A: RC0603FR-07301KL (YAGEO) has the highest inventory at 314913 units. For AEC-Q200 qualified alternatives, ERJ-3EKF3013V (Panasonic) provides 67636 units.
