Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX2403 is determined by strict equivalence across the following parameters: resistance value (240 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 (ROHS3, MSL 1).
All substitute parts listed maintain identical electrical specifications and mechanical compatibility. Packaging format (Tape & Reel) differs from the original part but does not affect functional equivalence. Dimensional variations within the 0603 package specification are acceptable per industry standards.

Engineering Selection Recommendations
For applications requiring AEC-Q200 automotive qualification, select from KTR03EZPF2403 (Rohm Semiconductor), CRCW0603240KFKEA (Vishay Dale), ERJ-3EKF2403V (Panasonic Electronic Components), or RMCF0603FT240K (Stackpole Electronics Inc). All four parts maintain active product status with full automotive compliance.
For non-automotive applications or where AEC-Q200 certification is not mandatory, CR0603-FX-2403ELF (Bourns Inc.) and RC0603FR-07240KL (YAGEO) are functionally equivalent alternatives with moisture-resistant thick film construction and ROHS3 compliance.
All substitute parts are available in Tape & Reel packaging format and maintain identical electrical performance within specified tolerances.
Frequently Asked Questions (FAQ)
Q: Can MCR03EZPFX2403 be replaced with KTR03EZPF2403? A: Yes. Both parts are manufactured by Rohm Semiconductor with identical electrical specifications (240 kOhms ±1%, 0.1W, 0603 package), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 automotive rating. KTR03EZPF2403 is currently active in production.
Q: What is the difference between AEC-Q200 rated and non-AEC-Q200 rated substitutes? A: AEC-Q200 certification indicates the component meets automotive industry reliability and qualification standards. KTR03EZPF2403, CRCW0603240KFKEA, ERJ-3EKF2403V, and RMCF0603FT240K carry this certification. CR0603-FX-2403ELF and RC0603FR-07240KL do not. Selection depends on application requirements.
Q: Are there dimensional differences between substitute parts? A: All parts conform to 0603 (1608 Metric) package specification. Minor dimensional variations exist within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width from 0.031" to 0.033" (0.80mm to 0.85mm), and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances.
Q: Can I use CR0603-FX-2403ELF or RC0603FR-07240KL in automotive applications? A: These parts lack AEC-Q200 certification. Use only if your application does not require automotive qualification. Both maintain identical electrical specifications and ROHS3 compliance.
Q: What is Moisture Sensitivity Level (MSL) 1? A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry this rating, allowing standard storage and handling procedures.
Q: Are all substitute parts available in the same packaging format? A: The original MCR03EZPFX2403 packaging format is not specified in available data. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.
