Engineering Selection Recommendations
For applications requiring AEC-Q200 automotive qualification, select from the following active parts: CRCW060313R7FKEA (Vishay Dale), ERJ-3EKF13R7V (Panasonic Electronic Components), or RMCF0603FT13R7 (Stackpole Electronics Inc). All three maintain full automotive certification and ROHS3 compliance.
ERJ-3EKF13R7V offers the highest inventory availability (57761 Pcs) among active AEC-Q200 qualified substitutes. CRCW060313R7FKEA provides the second-highest availability (15779 Pcs) with active product status. RMCF0603FT13R7 maintains active status with AEC-Q200 rating and adequate inventory (2321 Pcs).
For non-automotive applications where AEC-Q200 certification is not required, RC0603FR-0713R7L (YAGEO) is available with active product status and moisture-resistant composition, offering 5881 Pcs in inventory.
MCR03ERTF13R7 (Rohm Semiconductor) is available in higher quantity (5434 Pcs) but is discontinued and lacks AEC-Q200 certification in the provided specifications.
Frequently Asked Questions (FAQ)
Q: Can MCR03ERTF13R7 replace MCR03EZPFX13R7 in automotive applications?
A: MCR03ERTF13R7 matches all electrical and mechanical parameters but is discontinued and does not list AEC-Q200 certification in the provided data. For automotive applications requiring AEC-Q200 compliance, use CRCW060313R7FKEA, ERJ-3EKF13R7V, or RMCF0603FT13R7 instead.
Q: Are all substitute parts physically compatible with the original PCB footprint?
A: All substitute parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within tolerance (length 1.55mm to 1.60mm, height 0.50mm to 0.55mm), which are within standard PCB design tolerances for 0603 components.
Q: What is the difference between RC0603FR-0713R7L and the AEC-Q200 qualified alternatives?
A: RC0603FR-0713R7L is rated for moisture-resistant applications but does not carry AEC-Q200 automotive certification. It is suitable for non-automotive or non-safety-critical applications. For automotive use, select an AEC-Q200 qualified part.
Q: Which substitute offers the best availability?
A: ERJ-3EKF13R7V (Panasonic Electronic Components) provides the highest inventory with 57761 Pcs in stock and maintains active product status with full AEC-Q200 certification.
Q: Are all parts ROHS3 compliant?
A: Yes, all listed parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements.
