Substitute Part Grouping Explanation
Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (24.3 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 termination count (2). All substitute parts listed maintain these core electrical and mechanical specifications. Parts are grouped into two categories: direct equivalents with automotive AEC-Q200 certification matching the original specification, and similar alternatives with equivalent performance characteristics but differing feature sets.

Engineering Selection Recommendations
For applications requiring automotive qualification, CRCW060324R3FKEA (Vishay Dale), ERJ-3EKF24R3V (Panasonic), and RMCF0603FT24R3 (Stackpole) are direct equivalents with active product status and AEC-Q200 certification. These parts are suitable for automotive and high-reliability applications with identical electrical performance and thermal characteristics.
MCR03ERTF24R3 (Rohm Semiconductor) provides electrical equivalence but carries discontinued status, limiting long-term supply availability.
RC0603FR-0724R3L (YAGEO) maintains all core electrical specifications with active product status. The moisture-resistant feature provides additional environmental protection, though automotive AEC-Q200 certification is not specified.
All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard PCB assembly processes.
Frequently Asked Questions (FAQ)
Q: Can MCR03ERTF24R3 replace MCR03EZPFX24R3 in automotive applications? A: MCR03ERTF24R3 matches all electrical and mechanical specifications but lacks documented automotive AEC-Q200 certification. Both parts are discontinued at DiGi Electronics. For new designs, active alternatives with AEC-Q200 certification are preferred.
Q: Are CRCW060324R3FKEA, ERJ-3EKF24R3V, and RMCF0603FT24R3 interchangeable? A: Yes. All three parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package, temperature coefficient, and operating range. All carry AEC-Q200 certification and active product status. Selection may be based on availability, packaging format (Tape & Reel), or supply chain preference.
Q: What is the difference between RC0603FR-0724R3L and the AEC-Q200 certified alternatives? A: RC0603FR-0724R3L maintains identical electrical specifications and package compatibility. The primary difference is the absence of automotive AEC-Q200 certification and the inclusion of moisture-resistant features. This part is suitable for non-automotive applications or where moisture resistance is beneficial.
Q: Are all substitute parts available in the same packaging format? A: MCR03EZPFX24R3 and MCR03ERTF24R3 are available in Cut Tape (CT) & Digi-Reel format. CRCW060324R3FKEA, ERJ-3EKF24R3V, RMCF0603FT24R3, and RC0603FR-0724R3L are available in Tape & Reel (TR) format. Verify packaging requirements with your procurement process.
Q: Do all parts meet ROHS3 compliance? A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard PCB assembly and storage conditions.
