Crystals Procurement Notes

Verify the specific datasheet version for the 8Z-27.000MAAJ-T to confirm exact electrical parameters and mechanical tolerances before integration. Ensure that the target circuit design accommodates the specified 18 pF load capacitance and 100 Ohm ESR values. Confirm compliance with RoHS standards if required by the end-product regulations. Cross-reference the package dimensions against the PCB footprint library to guarantee accurate placement during manufacturing.

Crystals Selection Notes

Select this component when a standard 27 MHz reference signal is required for digital logic or communication interfaces in consumer electronics. The ±30 ppm stability is suitable for general-purpose timing applications where high precision is not critical. Consider the 100 Ohm ESR value when designing oscillator circuits to ensure proper startup conditions. The SMD form factor makes it appropriate for space-constrained printed circuit board layouts requiring reliable surface attachment.

Crystals Part Context

This part belongs to the 8Z series of surface-mount crystals from TXC Corporation. These components are designed as direct replacements for traditional through-hole HC-49/US crystals, allowing manufacturers to transition to smaller footprints without redesigning existing circuit architectures significantly. The series emphasizes high pullability and low ESR for efficient operation in various digital systems.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz SMD crystals with matching 18 pF load capacitance and similar dimensional constraints. Verify that alternative parts maintain comparable ESR levels and frequency stability specifications to ensure circuit compatibility.
