Crystals Procurement Notes

Verify the specific ordering suffix against official CTS documentation to ensure correct load capacitance and tolerance specifications. Confirm moisture sensitivity level (MSL 1) handling requirements during assembly. Check for RoHS3 compliance status if environmental regulations apply. Ensure the 4-SMD footprint matches the target PCB layout dimensions precisely before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 30.72 MHz reference with ±10 ppm stability is required. Ensure the circuit design accommodates a 9 pF load capacitance and 80 Ohm ESR. Verify that the operating temperature range of -20°C to 70°C meets the application environment constraints. Confirm compatibility with surface mount reflow soldering processes for the 4-SMD package.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages for general-purpose timing needs. The 402F3071XIJR specifically targets applications requiring stable 30.72 MHz operation in small form factors. It complements other components in the 402 family with similar electrical characteristics but different frequency or packaging options.

Crystals Replacement Considerations

Direct substitutes must match the 30.72 MHz frequency, 9 pF load capacitance, and 4-SMD package. Verify equivalent ESR and stability ratings. Cross-reference with CTS internal part numbers or industry-standard equivalents ensuring identical pinout and mechanical dimensions for seamless integration.
