Crystals Procurement Notes

Verify the specific part number against official TXC documentation to confirm current availability status, as some listings may indicate discontinued or obsolete status. Ensure that the HC-49/US footprint matches the target PCB layout requirements. Confirm compliance with RoHS3 specifications if required by the end product regulations. Cross-reference the manufacturer's latest datasheet for any potential specification updates or changes prior to final procurement decisions.

Crystals Selection Notes

Select this component when a standard 28.224 MHz frequency is required for digital clock generation or data transmission interfaces. The ±30 ppm stability suits general-purpose timing applications where high precision is not critical. The HC-49/US SMD form factor allows for compact board designs while maintaining robust mechanical mounting. Consider the operating temperature range limits when designing for extreme environmental conditions.

Crystals Part Context

This crystal belongs to the 9C Series from TXC Corporation, which specializes in surface mount type crystal units. The series is characterized by a wide range of standard frequencies and high mass production capability. These components are engineered to provide reliable frequency control for consumer electronics and communication devices, offering a balance between performance and cost-effectiveness.

Crystals Replacement Considerations

Direct substitutes include other 28.224 MHz crystals with matching 18 pF load capacitance and HC-49/US SMD packaging. Verify ESR values near 30 Ohms and ±30 ppm stability to ensure circuit compatibility. Alternative manufacturers may offer similar specifications, but impedance matching and thermal characteristics must be validated before substitution.
