Engineering Selection Recommendations
For applications requiring automotive AEC-Q200 qualification, select from the direct manufacturer equivalents: CRCW0603169KFKEA (Vishay Dale), ERJ-3EKF1693V (Panasonic Electronic Components), or RMCF0603FT169K (Stackpole Electronics Inc). All three maintain active product status with full AEC-Q200 compliance and ROHS3 certification.
For non-automotive applications where AEC-Q200 qualification is not mandatory, CR0603-FX-1693ELF (Bourns Inc.), RC0603FR-07169KL (YAGEO), and RC1608F1693CS (Samsung Electro-Mechanics) provide equivalent electrical performance with moisture-resistant thick film construction and active availability.
All substitute parts are ROHS3 compliant with MSL rating 1 (Unlimited) and identical operating temperature ranges, ensuring direct functional replacement in circuit designs.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-1693ELF as a direct replacement for MCR03EZPFX1693 in automotive applications?
A: CR0603-FX-1693ELF is not AEC-Q200 qualified. For automotive applications requiring AEC-Q200 certification, use CRCW0603169KFKEA, ERJ-3EKF1693V, or RMCF0603FT169K instead.
Q: Are all substitute parts physically compatible with the original PCB layout?
A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical footprint dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm), ensuring direct PCB compatibility.
Q: What is the difference between AEC-Q200 rated and moisture-resistant variants?
A: AEC-Q200 rated parts (CRCW0603169KFKEA, ERJ-3EKF1693V, RMCF0603FT169K) meet automotive qualification standards. Moisture-resistant variants (CR0603-FX-1693ELF, RC0603FR-07169KL, RC1608F1693CS) provide enhanced moisture protection without automotive certification. Selection depends on application requirements.
Q: Do all substitute parts have the same temperature coefficient?
A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, ensuring equivalent thermal performance.
Q: Which substitute offers the highest inventory availability?
A: RC0603FR-07169KL (YAGEO) has the highest inventory at 475,161 pieces. ERJ-3EKF1693V (Panasonic) follows with 279,593 pieces.
