Crystals Procurement Notes

Verify the specific ordering suffix to confirm exact electrical parameters such as load capacitance and ESR, as variations exist within the SXT3249 series. Ensure compatibility with reflow soldering profiles specified in the official datasheet. Confirm RoHS3 compliance status if required by project specifications. Cross-reference the manufacturer's part number against authorized distributor catalogs to avoid counterfeit components. Validate that the selected variant matches the circuit design requirements for frequency and packaging.

Crystals Selection Notes

Select this component when a 18.432 MHz reference is required with ±30 ppm stability. The 9 pF load capacitance must match the oscillator circuit design. Consider the 70 Ohm ESR limit for driver capability. The 4-SMD no-lead package dictates PCB footprint constraints. Verify temperature range suitability for the intended operating environment. Compare against alternative frequencies if system flexibility allows.

Crystals Part Context

This part belongs to the SXT324 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and packages. The SXT3249BA07 variant specifically denotes the 18.432 MHz frequency with 9 pF load capacitance. Other variants in the series may differ in frequency, stability, or physical dimensions. The series is designed for general-purpose timing applications in consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz crystals with identical 9 pF load capacitance and 4-SMD no-lead packaging. Verify ESR limits and stability tolerances match the original ±30 ppm specification. Check pinout compatibility and thermal characteristics. Alternative manufacturers may offer similar specifications but require validation of mechanical and electrical parameters.
