Crystals Procurement Notes

Verify the specific suffix AAIB against official datasheets to confirm the 16pF load capacitance requirement. Ensure circuit design matches the ±30ppm tolerance and 80 Ohm ESR specifications. Confirm that the operating temperature range of -10°C to +60°C aligns with the application environment requirements before procurement.

Crystals Selection Notes

Select this component when a 12 MHz reference signal is required with moderate stability. The 16pF load capacitance must match the oscillator circuit design. Consider the HC-49/US form factor for space constraints. Verify that the ±30ppm tolerance meets system accuracy needs compared to tighter alternatives.

Crystals Part Context

This part belongs to the HC-49/U-S series of crystals from Citizen Finedevice. The series offers various frequency and capacitance options in a standardized through-hole package. The AAIB suffix denotes specific electrical parameters including the 16pF load capacitance and ±30ppm tolerance, distinguishing it from other variants like BBQB or ABJB.

Crystals Replacement Considerations

The HC-49/U-S12000000BBQT is listed as a parameter-equivalent substitute. Verify compatibility regarding the 10pF vs 16pF load capacitance difference and ensure the oscillator circuit supports the alternative specification.
