Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the package dimensions match the target PCB footprint. Check RoHS compliance status if restricted substances are a concern for the final assembly. Ensure the active status is current before placing orders.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required for low-power timing applications. The 90 kΩ ESR value indicates suitability for oscillator circuits designed for higher impedance loads. The ±20 ppm tolerance provides adequate accuracy for general timekeeping tasks rather than high-precision metrology. Consider the SMD2012-2P form factor for space-constrained board layouts.

Crystals Part Context

This part belongs to the Meritek MXT series of quartz crystals, which are engineered for surface-mount technology. The series typically offers various frequency options and package sizes to support diverse electronic designs. The MXT29FI32K768 specifically targets the common 32.768 kHz application, widely used in battery-powered devices due to its low power consumption characteristics.

Crystals Replacement Considerations

The MXT19FI32K768 is a documented alternative within the same product family, offering similar electrical characteristics. Verify package compatibility and pin configuration before substitution. Other manufacturers may offer cross-references, but direct functional equivalence must be confirmed via datasheet comparison.
