MCR03EZPFX4701 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX4701 is a 4.7 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 product lines that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX4701 is determined by strict equivalence across the following parameters: resistance value (4.7 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 (AEC-Q200, ROHS3). Dimensional variations within the 0603 package specification are acceptable provided all electrical parameters remain identical.

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 requirements but differ in specific features (such as moisture resistance or anti-sulfur coating) or lack explicit AEC-Q200 rating. These parts are functionally compatible but may require application-specific evaluation.

Engineering Selection Recommendations

For applications requiring strict AEC-Q200 automotive compliance, direct substitutes with active product status are: CRCW06034K70FKEA, CRCW06034K70FKEC, ERJ-3EKF4701V, RMCF0603FG4K70, RMCF0603FT4K70, and RCA06034K70FKEA. All maintain identical electrical specifications and automotive qualification.

RMCF0603FT4K70 offers the highest inventory availability (458,307 pcs) with active status and Cut Tape packaging suitable for automated assembly. CRCW06034K70FKEA provides equivalent specifications with substantial inventory (5,000,300 pcs) and active product status.

For non-automotive applications or where AEC-Q200 is not mandatory, CR0603-FX-4701ELF, CRG0603F4K7, and RC0603FR-074K7L are functionally compatible alternatives with active status and high inventory levels.

Frequently Asked Questions (FAQ)

Q: Can CRCW06034K70FKEA directly replace MCR03EZPFX4701 in automotive applications?

A: Yes. CRCW06034K70FKEA maintains identical electrical specifications (4.7 kΩ ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C) and AEC-Q200 automotive qualification. The part is pin-compatible in 0603 package format.

Q: What is the difference between RMCF0603FT4K70 and RMCF0603FG4K70?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: RMCF0603FT4K70 is supplied in Cut Tape (CT) & Digi-Reel® format, while RMCF0603FG4K70 is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements.

Q: Are CR0603-FX-4701ELF and CRG0603F4K7 suitable replacements for automotive designs?

A: These parts meet all electrical and mechanical specifications but lack explicit AEC-Q200 automotive certification. They are functionally compatible for non-automotive applications or where automotive qualification is not a design requirement.

Q: Why do some substitute parts have different physical dimensions within the 0603 package?

A: The 0603 (1608 Metric) package specification allows minor dimensional variations. All listed parts conform to the 0603 standard and are mechanically compatible. Typical variations include length (0.061" to 0.063") and height (0.020" to 0.022"), which do not affect PCB assembly or electrical performance.

Q: Which substitute offers the best long-term availability?

A: RMCF0603FT4K70 (Stackpole Electronics Inc) and CRCW06034K70FKEA (Vishay Dale) both maintain active product status with substantial inventory levels, ensuring continued availability for production and design cycles.
