MCR03EZPFX7500 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX7500 is a 750 Ohm ±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 eligibility for the MCR03EZPFX7500 is determined by strict equivalence across the following parameters: resistance value (750 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 compliance certifications (AEC-Q200, ROHS3, REACH Unaffected).

Parts are classified into two categories:

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

Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant composition instead of automotive AEC-Q200 rating. These parts are suitable for applications where automotive qualification is not mandatory.

Engineering Selection Recommendations

For Automotive Applications Requiring AEC-Q200 Compliance:

CRCW0603750RFKEA (Vishay Dale) is the primary direct substitute. This part maintains full AEC-Q200 automotive qualification with active product status and highest inventory availability (1,000,400 units). Packaging is available in Cut Tape and Digi-Reel formats.

ERJ-3EKF7500V (Panasonic Electronic Components) and RMCF0603FT750R (Stackpole Electronics Inc) are secondary direct substitutes, both with active status and AEC-Q200 compliance. RMCF0603FG750R (Stackpole Electronics Inc) provides an additional active alternative with AEC-Q200 rating.

For Non-Automotive Applications or Where Automotive Qualification Is Not Required:

CR0603-FX-7500ELF (Bourns Inc.) and RC0603FR-07750RL (YAGEO) meet all electrical and mechanical specifications with moisture-resistant composition. Both parts are active with substantial inventory. These options are suitable only when AEC-Q200 automotive qualification is not a design requirement.

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-7500ELF or RC0603FR-07750RL as direct replacements for MCR03EZPFX7500 in automotive applications?

A: No. CR0603-FX-7500ELF and RC0603FR-07750RL do not carry AEC-Q200 automotive qualification. Use these parts only in applications where automotive qualification is not required. For automotive designs, select from CRCW0603750RFKEA, ERJ-3EKF7500V, RMCF0603FT750R, or RMCF0603FG750R.

Q: Are all substitute parts available in the same packaging formats?

A: Packaging availability varies. CRCW0603750RFKEA is available in Cut Tape (CT) and Digi-Reel formats. CRCW0603750RFKEB, ERJ-3EKF7500V, RMCF0603FT750R, RMCF0603FG750R, CR0603-FX-7500ELF, and RC0603FR-07750RL are available in Tape & Reel (TR) format. Verify packaging requirements with your procurement specifications.

Q: Do all substitute parts meet the same temperature coefficient and operating temperature range?

A: Yes. All listed substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, matching the MCR03EZPFX7500 specifications.
