Crystals Procurement Notes

Verify the current lifecycle status as the product may be discontinued or subject to limited availability. Confirm RoHS compliance details and specific lot traceability requirements before finalizing procurement orders. Ensure compatibility with existing supply chain channels for end-of-life management.

Crystals Selection Notes

Select this component when a 4 MHz fundamental mode crystal with 20 pF load capacitance is required. Verify that the application environment stays within the specified -10°C to +60°C operating range. Consider the HC-49/U package dimensions for adequate board space allocation.

Crystals Part Context

This part belongs to the TXC 9B series of MHz crystals. It shares the HC-49/U form factor with other models in the lineup but differs in frequency and load capacitance specifications. The series is known for high Q-factor and low aging characteristics suitable for precision timing.

Crystals Replacement Considerations

Direct substitutes include the AS-4.000MDHK-B and AT-4.000MDHC-T from TXC Corporation, provided they meet the same electrical and mechanical constraints.
