MCR03EZPFX1073 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1073 is a 107 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 circuit board integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCR03EZPFX1073 is determined by strict equivalence across the following critical parameters: resistance value (107 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, REACH Unaffected, EAR99).

Substitute parts are categorized into two groups:

Direct Substitutes maintain full AEC-Q200 automotive qualification: CRCW0603107KFKEA (Vishay Dale), ERJ-3EKF1073V (Panasonic Electronic Components), and RMCF0603FT107K (Stackpole Electronics Inc).

Similar Substitutes meet all electrical and mechanical specifications but feature moisture-resistant construction instead of automotive AEC-Q200 rating: CR0603-FX-1073ELF (Bourns Inc.) and RC0603FR-07107KL (YAGEO).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring strict automotive AEC-Q200 compliance, direct substitutes CRCW0603107KFKEA, ERJ-3EKF1073V, and RMCF0603FT107K are functionally equivalent to the discontinued MCR03EZPFX1073. All three maintain identical electrical specifications, operating temperature range, and automotive qualification status. RMCF0603FT107K offers the highest inventory availability at 145,553 pieces.

For non-automotive applications or where AEC-Q200 certification is not a design requirement, CR0603-FX-1073ELF and RC0603FR-07107KL provide equivalent electrical performance with moisture-resistant construction. Both parts are actively manufactured and widely available.

All substitute options maintain RoHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-1073ELF or RC0603FR-07107KL be used in automotive applications originally designed for MCR03EZPFX1073?

A: These parts meet all electrical and mechanical specifications but lack AEC-Q200 automotive qualification. Use only if your application does not require automotive-grade component certification.

Q: Are all substitute parts physically interchangeable with MCR03EZPFX1073?

A: Yes. All substitutes use the 0603 (1608 Metric) package with identical termination count (2) and compatible maximum seated height specifications (0.022" / 0.55mm), enabling direct PCB footprint compatibility.

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

A: Direct substitutes (CRCW0603107KFKEA, ERJ-3EKF1073V, RMCF0603FT107K) carry AEC-Q200 automotive qualification. Similar substitutes (CR0603-FX-1073ELF, RC0603FR-07107KL) feature moisture-resistant construction without automotive certification.

Q: Do all substitutes maintain the same temperature coefficient and operating range?

A: Yes. All substitute parts specify ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, matching the original MCR03EZPFX1073.

Q: Which substitute offers the best inventory availability?

A: RMCF0603FT107K by Stackpole Electronics Inc provides the highest stock level at 145,553 pieces, with active product status and Tape & Reel packaging.
