Crystals Procurement Notes

Verify the specific suffix 'CJT' against official CTS documentation to confirm packaging type and tape/reel specifications. Ensure the selected variant matches the required load capacitance and tolerance for your circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 30.72 MHz fundamental crystal with 9pF load capacitance is required. The 4-SMD package offers a small form factor compared to through-hole alternatives. Consider the ±30 ppm tolerance and 80 Ohm ESR limits to ensure compatibility with the oscillator circuit's drive level and stability requirements within the specified industrial temperature range.

Crystals Part Context

This component belongs to the 402 Series of MHz crystals from CTS-Frequency Controls. The series provides various frequencies and packages for general-purpose timing applications. The 402F30733CJT specifically utilizes the smaller 4-SMD outline, distinguishing it from larger HC-49/US or other SMD variants offered by the manufacturer for different power and size constraints.

Crystals Replacement Considerations

Direct substitutes include the 402F30733CLR, which shares the same electrical characteristics but differs in load capacitance (12pF). Verify that the circuit can accommodate the capacitance change. Other 30.72 MHz crystals from different manufacturers require careful evaluation of ESR, drive level sensitivity, and package dimensions to ensure functional equivalence.
