Crystals Procurement Notes

Verify the specific datasheet version from Suntsu Electronics to confirm current RoHS compliance status and exact ESR values, as manufacturing processes may evolve. Ensure the ordering suffix matches the required tape and reel or bulk packaging configuration if applicable. Cross-reference the pinout diagram with the target PCB footprint to prevent installation errors during surface mount assembly.

Crystals Selection Notes

Select this component when a 24 MHz fundamental frequency with 18 pF load capacitance is required for space-constrained designs. The 4-SMD package offers a small footprint compared to through-hole alternatives. Consider the ±30 ppm stability requirement against the application's jitter sensitivity needs. Verify that the 120 Ohm ESR aligns with the oscillator circuit's drive level specifications to ensure proper startup and longevity.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series provides various frequency options within a standardized 4-SMD form factor. The model number indicates the specific frequency (24.000M), load capacitance (18pF), and package type. It serves as a direct replacement for other 24 MHz SMD crystals in existing designs, provided the electrical parameters match the original circuit requirements.

Crystals Replacement Considerations
