MCR03EZPFX24R0 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX24R0 is a 24 Ohm ±1% thick film chip resistor in 0603 (1608 Metric) package rated for 0.1W power dissipation. Manufactured by Rohm Semiconductor, this component meets AEC-Q200 automotive qualification standards and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications requiring automotive-grade reliability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (24 Ohms), tolerance (±1%), power rating (0.1W), package format (0603/1608 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

All identified substitutes maintain these core electrical and mechanical specifications. Direct substitutes (CRCW060324R0FKEA, ERJ-3EKF24R0V, RMCF0603FT24R0) are functionally identical with AEC-Q200 automotive qualification. Similar substitutes (AC0603FR-0724RL, CR0603-FX-24R0ELF, RC0603FR-0724RL, RC1608F240CS) meet all electrical parameters and compliance requirements; some include additional moisture-resistant features beyond base specifications.

Engineering Selection Recommendations

For applications requiring strict AEC-Q200 automotive compliance, select from the direct substitutes: CRCW060324R0FKEA (Vishay Dale), ERJ-3EKF24R0V (Panasonic), or RMCF0603FT24R0 (Stackpole Electronics). All three maintain identical electrical specifications and automotive qualification status.

For non-automotive applications or where AEC-Q200 is not mandated, similar substitutes provide equivalent electrical performance with ROHS3 compliance and MSL 1 rating. AC0603FR-0724RL and RC0603FR-0724RL offer high inventory availability. CR0603-FX-24R0ELF and RC1608F240CS include moisture-resistant features.

All substitutes are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Selection should prioritize active status parts with adequate inventory for production requirements.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-24R0ELF or RC0603FR-0724RL as direct replacements for MCR03EZPFX24R0 in automotive applications?

A: These parts meet all electrical and mechanical specifications (24 Ohm ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). However, they lack explicit AEC-Q200 certification. Use only if your application does not mandate automotive qualification or if design review permits equivalent performance-based substitution.

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

A: Direct substitutes (CRCW060324R0FKEA, ERJ-3EKF24R0V, RMCF0603FT24R0) carry AEC-Q200 automotive qualification matching the original part. Similar substitutes meet all electrical parameters and compliance standards but may lack specific automotive certifications or include additional features such as moisture resistance.

Q: Are all substitutes physically interchangeable in the 0603 package?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package format with identical footprint dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm nominal). Physical board-level compatibility is confirmed across all parts.

Q: Which substitute offers the best inventory availability?

A: RC0603FR-0724RL (YAGEO) provides the highest inventory at 210,951 pieces. RMCF0603FT24R0 (Stackpole) offers 159,464 pieces. ERJ-3EKF24R0V (Panasonic) provides 121,146 pieces. All three support high-volume production requirements.

Q: Do all substitutes meet RoHS and REACH compliance?

A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level is MSL 1 (unlimited) across all parts, indicating no special storage or handling requirements.
