Crystals Procurement Notes

Verify the specific model suffix against official CTS datasheets to ensure compatibility with your circuit requirements. Confirm that the 18pF load capacitance matches your oscillator circuit design. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the 4-SMD footprint dimensions align with your PCB fabrication capabilities before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 44 MHz fundamental frequency is required with ±30 ppm tolerance. Consider the 18pF load capacitance requirement for proper circuit tuning. Evaluate the 60 Ohm ESR against your oscillator amplifier specifications. The 4-SMD package size should be verified against available board space constraints and thermal management needs for the target application environment.

Crystals Part Context

This part belongs to the CTS 403 Series of surface-mount crystals. The series offers various frequencies and package options for timing applications. The 403I35D44M00000 specifically targets 44 MHz operations. It shares common packaging characteristics with other members of the 403 family while differing in electrical parameters such as frequency and load capacitance.

Crystals Replacement Considerations

The 403I35E48M00000 is listed as a similar alternative by distributors, though it operates at 48 MHz. Verify frequency compatibility before substitution. The 8Z-48.000MAGJ-T from TXC Corporation is another comparable option but differs in manufacturer and potentially pinout or electrical characteristics. Always confirm technical equivalence with official documentation.
