Crystals Procurement Notes

Verify current availability status as this part may be discontinued or subject to limited supply constraints. Confirm RoHS compliance details through official manufacturer documentation prior to integration. Ensure the specific package variant matches the PCB footprint requirements. Check for any recent product change notices that might affect specifications or sourcing channels.

Crystals Selection Notes

Select this component when a 18.432 MHz reference is required for digital logic timing. The 20 pF load capacitance must match the oscillator circuit design parameters. Consider the ±20 ppm tolerance against system accuracy requirements. The 4-SMD package size suits space-constrained layouts compared to larger through-hole alternatives.

Crystals Part Context

This crystal belongs to the 7B series of miniature SMD resonators from TXC Corporation. It serves as a frequency-determining element in electronic circuits requiring precise timing references. The 18.432 MHz frequency is commonly used in baud rate generation for serial communication protocols.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz crystals with identical 20 pF load capacitance and 4-SMD 5x3mm footprint. Verify ESR compatibility and temperature range alignment before substitution.
