Crystals Procurement Notes

Verify the specific load capacitance requirement of 15 pF against the target oscillator circuit design to ensure frequency accuracy. Confirm that the HC49/SMD package dimensions align with the PCB land pattern and clearance requirements. Ensure the manufacturing source is identified as Transko Electronics, Inc., and validate the Tape & Reel packaging specification for compatibility with existing SMT production lines.

Crystals Selection Notes

Select this component when a fundamental frequency of 12.288 MHz is required with a 15 pF load capacitance. The HC49/SMD form factor is suitable for applications needing a balance between performance and compactness compared to through-hole alternatives. Consider the operating temperature range and stability specifications if the application involves extreme environmental conditions or high-precision timing needs beyond standard commercial grades.

Crystals Part Context

This part belongs to the HC49/SMD series of crystals from Transko Electronics, Inc., which are widely used in consumer electronics and industrial control systems. The 12.288 MHz frequency is a common choice for baud rate generation in serial communication protocols due to its divisibility into standard rates like 9600 bps. The TR suffix indicates bulk reel packaging for high-volume manufacturing.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC49/SMD crystals with identical 12.288 MHz frequency and 15 pF load capacitance. Verify equivalent electrical parameters such as ESR and drive level before substitution. Cross-reference package dimensions to ensure mechanical compatibility.
