Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the 4-SMD footprint matches the target PCB layout dimensions. Check RoHS compliance status if restricted substances are mandated by project requirements.

Crystals Selection Notes

Select this component when a 44 MHz fundamental frequency is required with tight tolerance constraints. Ensure the circuit design accounts for the specified 18 pF load capacitance to maintain accuracy. Verify that the 3.2x2.5 mm package size fits within the available board space constraints compared to larger through-hole alternatives.

Crystals Part Context

This part belongs to the CTS 403 series of general-purpose quartz crystals. The series provides standard frequency control solutions for consumer and industrial electronics. The 403C35D variant specifically denotes the 4-SMD package style and associated electrical characteristics defined by the manufacturer's internal coding system.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers include 403I35E48M00000 and 8Z-48.000MAGJ-T from other manufacturers, though these differ in frequency. Direct functional equivalents with identical 44 MHz specifications should be sourced via official distributor cross-reference tools.
