Crystals Procurement Notes

Verify that the replacement part matches the exact 20pF load capacitance and 100 Ohm ESR specifications. Confirm the 4-pin SMD3225-4P footprint compatibility with existing PCB layouts. Ensure the new component meets the -40°C to +85°C temperature rating required for your specific application environment. Cross-reference the ±10 ppm tolerance to guarantee signal integrity in timing-critical circuits.

Crystals Selection Notes

Select this component when a precise 12.288 MHz reference is required for digital communication interfaces such as UART or SPI. The 20pF load capacitance is standard for many microcontroller crystal inputs. Consider the 100 Ohm ESR value to ensure proper oscillation startup conditions within the host circuit design. The wide temperature range makes it suitable for outdoor or uncontrolled indoor installations.

Crystals Part Context

This model belongs to the SCTF SX3B series of passive quartz crystals. It shares the same nominal frequency and general characteristics with variants like SX3B12.288F1210F30, which utilizes a 12pF load capacitance instead of 20pF. The suffix '20' in the model number explicitly denotes the 20pF load capacitance requirement, distinguishing it from other load capacitance options within the product family.
