Crystals Procurement Notes

Verify that the specific part number matches the required frequency, tolerance, and package dimensions. Confirm compliance with environmental directives such as RoHS and REACH if applicable to the target market. Ensure the load capacitance aligns with the oscillator circuit design requirements. Check for any specific storage or handling instructions related to the hermetic seal integrity during procurement and inventory management.

Crystals Selection Notes

Select this component when a through-hole, hermetically sealed crystal is required for 8 MHz applications. Consider the ±20 ppm tolerance and ±50 ppm stability against system timing accuracy needs. Evaluate the 80 Ω ESR limit to ensure compatibility with the driving circuit's power constraints. Verify that the HC-49/US package fits the available board space and mounting constraints compared to surface-mount alternatives.

Crystals Part Context

This component belongs to the Abracon ABL series of microprocessor crystals. The series offers various frequencies and tolerances in the HC-49/US package. These crystals are characterized by high reliability and hermetic sealing, distinguishing them from non-sealed variants. The ABL-8.000MHZ-B2 represents a specific configuration optimized for general-purpose digital logic timing applications.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/US crystals with identical 8 MHz frequency, ±20 ppm tolerance, and 18 pF load capacitance. Ensure equivalent ESR limits and hermetic sealing properties are maintained. Cross-reference package dimensions to guarantee mechanical fit without modification.
