Crystals Procurement Notes

Verify the specific ordering suffix to confirm the exact frequency, load capacitance, and packaging configuration. Ensure the selected variant matches the required operating temperature range and stability specifications for the target application. Confirm RoHS compliance status if environmental regulations apply. Cross-reference the manufacturer part number with distributor databases to ensure accurate sourcing and availability.

Crystals Selection Notes

Select this component when a 16 MHz fundamental mode crystal with 18 pF load capacitance is required. The 50 Ohm ESR and ±20 ppm stability suit precision timing circuits. Consider the 60°C operating limit for thermal constraints. The 7.20mm x 5.20mm footprint must fit the PCB layout. Verify compatibility with the oscillator circuit's drive level requirements.

Crystals Part Context

This part belongs to the Cardinal CX5 series of ceramic surface mount crystals. The series offers a wide frequency range from 7.3728 MHz to 150 MHz and includes fundamental and overtone modes. Variants are available in 2-pad and 4-pad packages with various operating temperature ranges. The CX5 series is designed for applications requiring tight stabilities and low drive levels.

Crystals Replacement Considerations

Potential substitutes include Abracon ABM3B-24.576MHZ-B2-T and ECS ECS-245.7-18-30B-JEM-TR, though these differ in frequency. Verify electrical parameters such as frequency, load capacitance, and ESR before substitution. Ensure mechanical dimensions and mounting style are compatible with the existing design.
