Frequently Asked Questions (FAQ)

Q: Can the SRR6603-472ML be used as a direct replacement for the UP0.4SC-472-R?

A: Yes. The SRR6603-472ML meets all critical electrical parameters including inductance (4.7 mH), current rating (60 mA), DC resistance (13.9 Ohm maximum), and Q factor (50 @ 100 kHz). Physical dimensions are compatible with surface mount assembly, and both parts feature identical shielding and packaging specifications.

Q: Are there differences in operating temperature ranges between these parts?

A: The UP0.4SC-472-R operates from -40°C to 125°C, while the SRR6603-472ML operates from -55°C to 125°C. The Bourns part extends the lower temperature limit by 15°C, making it suitable for applications requiring enhanced cold-temperature performance.

Q: Do both parts have the same physical footprint?

A: The parts have compatible footprints for surface mount assembly. Length is identical at 0.260" (6.60mm). Width differs by 0.002" (0.05mm) and height by 0.003" (0.08mm), variations that fall within standard PCB design tolerances for component placement and soldering.

Q: What is the significance of the ±20% inductance tolerance?

A: The ±20% tolerance indicates that the actual inductance value may vary between 3.76 mH and 5.64 mH. Both the UP0.4SC-472-R and SRR6603-472ML share this tolerance specification, ensuring equivalent performance in circuits designed to accommodate this range.

Q: Are both parts RoHS compliant?

A: Yes. The UP0.4SC-472-R is RoHS Compliant, and the SRR6603-472ML is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions in electronic components.
