Substitute Part Grouping Explanation
Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (47.5 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).
Direct Substitutes maintain all electrical and mechanical specifications identical to the MCR03EZPFX4752:
- CRCW060347K5FKEA (Vishay Dale)
- ERJ-3EKF4752V (Panasonic Electronic Components)
- RMCF0603FG47K5 (Stackpole Electronics Inc)
- RMCF0603FT47K5 (Stackpole Electronics Inc)
Similar Substitutes meet all core electrical parameters and package requirements but differ in specific features or certifications:
- CR0603-FX-4752ELF (Bourns Inc.) — Moisture Resistant feature instead of AEC-Q200 automotive rating
- RC0603FR-0747K5L (YAGEO) — Moisture Resistant feature instead of AEC-Q200 automotive rating

Engineering Selection Recommendations
For automotive applications requiring AEC-Q200 compliance, select from the direct substitutes: CRCW060347K5FKEA, ERJ-3EKF4752V, RMCF0603FG47K5, or RMCF0603FT47K5. All four maintain identical electrical specifications and automotive certification status.
For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-4752ELF and RC0603FR-0747K5L are functionally equivalent alternatives with active product status and full RoHS3 compliance.
Packaging format selection depends on supply chain requirements: CRCW060347K5FKEA and CR0603-FX-4752ELF are available in Tape & Reel format; ERJ-3EKF4752V in Tape & Reel; RMCF0603FG47K5 and RMCF0603FT47K5 in Cut Tape and Cut Tape & Digi-Reel formats respectively; RC0603FR-0747K5L in Cut Tape & Digi-Reel format.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-4752ELF or RC0603FR-0747K5L as direct replacements for MCR03EZPFX4752 in automotive circuits?
A: These parts meet all electrical and mechanical specifications but lack AEC-Q200 automotive certification. Use only if your application does not require automotive-grade qualification.
Q: What is the difference between RMCF0603FG47K5 and RMCF0603FT47K5?
A: Both are Stackpole Electronics RMCF series 47.5 kOhms ±1% 0603 resistors with identical electrical specifications. RMCF0603FG47K5 is supplied in Cut Tape format; RMCF0603FT47K5 is supplied in Cut Tape & Digi-Reel format. Selection depends on packaging and handling requirements.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitutes including MCR03EZPFX4752, CRCW060347K5FKEA, ERJ-3EKF4752V, RMCF0603FG47K5, RMCF0603FT47K5, CR0603-FX-4752ELF, and RC0603FR-0747K5L are ROHS3 compliant.
Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?
A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management.
Q: Which substitute has the highest inventory availability?
A: RC0603FR-0747K5L (YAGEO) has 519,651 pieces in stock, followed by RMCF0603FT47K5 (Stackpole) with 155,042 pieces.
