MCR03EZPFX28R0 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX28R0 is a 28 Ohms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This automotive-grade component meets AEC-Q200 qualification standards and is designed for high-reliability applications requiring stable resistance performance across extended temperature ranges. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines.

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX28R0 is determined by strict equivalence across the following parameters: resistance value (28 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 (ROHS3, REACH Unaffected, EAR99).

The identified substitute parts are grouped into two categories:

Direct Substitutes maintain full AEC-Q200 automotive qualification: MCR03ERTF28R0 (Rohm Semiconductor), CRCW060328R0FKEA (Vishay Dale), ERJ-3EKF28R0V (Panasonic Electronic Components), and RMCF0603FT28R0 (Stackpole Electronics Inc).

Similar Substitute meets all electrical and mechanical parameters but lacks explicit AEC-Q200 certification: RC0603FR-0728RL (YAGEO) features moisture-resistant thick film construction and maintains all core electrical specifications.

Engineering Selection Recommendations

For applications requiring maintained AEC-Q200 automotive qualification, select from active product status alternatives: CRCW060328R0FKEA (Vishay Dale), ERJ-3EKF28R0V (Panasonic Electronic Components), or RMCF0603FT28R0 (Stackpole Electronics Inc). All three maintain full compliance with automotive standards, ROHS3 certification, and unlimited moisture sensitivity rating.

CRCW060328R0FKEA offers the highest inventory availability (24,760 pcs) and active product status, making it the primary recommendation for new designs and high-volume procurement.

ERJ-3EKF28R0V provides the largest available stock (48,930 pcs) and represents an alternative from a major component manufacturer with established supply chain presence.

RMCF0603FT28R0 maintains AEC-Q200 qualification with moderate inventory (1,391 pcs) and active status.

RC0603FR-0728RL from YAGEO is suitable for non-automotive applications where AEC-Q200 certification is not required. This part features moisture-resistant thick film construction and maintains all electrical specifications with the highest available inventory (58,382 pcs).

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF28R0 directly replace MCR03EZPFX28R0?

A: MCR03ERTF28R0 matches all electrical and mechanical parameters but lacks explicit AEC-Q200 automotive certification listed in the provided specifications. Both are Rohm Semiconductor products with identical resistance, tolerance, power rating, package, and operating temperature range. Substitution depends on whether AEC-Q200 qualification is a design requirement.

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

A: Direct substitutes (CRCW060328R0FKEA, ERJ-3EKF28R0V, RMCF0603FT28R0) maintain AEC-Q200 automotive qualification. The similar substitute (RC0603FR-0728RL) meets all electrical and mechanical specifications but is rated for moisture-resistant applications without explicit automotive certification. Selection depends on application requirements.

Q: Are all substitutes physically compatible with the original PCB layout?

A: All substitute parts use the 0603 (1608 Metric) package with identical termination count (2). Physical dimensions vary slightly within tolerance: length ranges from 0.061" to 0.063" and height from 0.020" to 0.022". These variations are within standard PCB design tolerances for 0603 components and do not affect mechanical compatibility.

Q: Which substitute offers the best supply availability?

A: RC0603FR-0728RL (YAGEO) has the highest inventory at 58,382 pcs. For AEC-Q200 qualified alternatives, CRCW060328R0FKEA (Vishay Dale) offers 24,760 pcs and ERJ-3EKF28R0V (Panasonic) offers 48,930 pcs.

Q: Do all substitutes meet the same compliance standards?

A: All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. Automotive-qualified substitutes (CRCW060328R0FKEA, ERJ-3EKF28R0V, RMCF0603FT28R0) carry AEC-Q200 certification. RC0603FR-0728RL does not list AEC-Q200 qualification.
