Crystals Procurement Notes

Verify the specific suffix 'AAJ' against the manufacturer's official part number guide to ensure correct load capacitance and packaging specifications. Confirm that the required operating temperature range of -20°C to +70°C aligns with the application environment, as other variants may offer extended ranges. Cross-reference the datasheet for any recent revisions affecting mechanical or electrical parameters before finalizing procurement.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency with 18 pF load capacitance is required for space-constrained designs. The 4-SMD package offers a compact form factor suitable for high-density layouts. Ensure the system impedance matches the 80 Ohm ESR specification. Consider environmental constraints, as the -20°C to +70°C range may not suffice for harsh industrial applications requiring wider thermal tolerance.

Crystals Part Context

This component belongs to the 8Y series of SMD crystals from TXC Corporation, which are designed for general-purpose timing applications. The series provides various frequency options in standardized packages to facilitate design reuse across different product lines. The 8Y series emphasizes reliability and consistency in mass production environments.

Crystals Replacement Considerations

The 8Y-38.400MAAB-T is listed as a similar alternative, though it specifies a 6 pF load capacitance instead of 18 pF. Verify circuit compatibility regarding load capacitance changes before substitution. Other potential substitutes should match the 38.4 MHz frequency, 18 pF load, and 4-SMD package dimensions.
