Crystals Procurement Notes

Verify that the specific order matches the 9C04070005 part number exactly, as variations exist in load capacitance and package types within the same manufacturer line. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to purchase. Ensure storage conditions align with the specified temperature limits to maintain component integrity during handling and assembly processes.

Crystals Selection Notes

Select this component when a 4 MHz reference signal with moderate stability requirements is needed for space-constrained designs. The HC-49/US SMD form factor allows for automated placement while maintaining robust mechanical characteristics. Consider the 150 Ohm ESR value when designing the oscillator circuit to ensure proper startup and sustained operation without excessive power consumption or loading effects on the driving logic.

Crystals Part Context

This component belongs to the TXC Corporation crystal oscillator family, specifically designed for general-purpose timing applications. It serves as a foundational element in digital electronics where accurate frequency division and signal generation are critical. The product represents a balance between cost-effectiveness and performance, suitable for mass production environments requiring consistent electrical characteristics across large batches.

Crystals Replacement Considerations

Direct substitutes must match the 4.0000 MHz frequency, 27 pF load capacitance, and HC-49/US package dimensions. Verify that alternative parts offer comparable ±30 ppm stability and similar ESR values to prevent circuit malfunction. Cross-reference pinouts and mounting hole specifications if mechanical constraints are strict.
