Procurement Notes

Verify the specific suffix 'ASR' against official CTS documentation to confirm the exact load capacitance and temperature rating, as these parameters vary across the 416 series. Ensure the ordering part number matches the required electrical specifications for the target circuit design before procurement.

Selection Notes

Select this component when a 50 MHz fundamental mode crystal is required with a 12pF load capacitance. Consider the ±10ppm initial tolerance and ±20ppm total stability relative to system requirements. Verify that the 4-SMD footprint fits the PCB layout constraints.

Part Context

This part belongs to the CTS 416 Series of high-performance crystals. The series offers various load capacitances and temperature ranges. The 416F50012ASR specifically denotes the 50 MHz frequency, 12pF load, and extended temperature range variant within this product family.

Replacement Considerations

Cross-reference with other 416 series parts such as 416F50012AAR or 416F50012ALR if different packaging or temperature ratings are acceptable. Confirm pin compatibility and electrical equivalence with any substitute.
