Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix T1-E3 against official Vishay documentation to confirm RoHS compliance and tape-and-reel packaging specifications. Confirm that the part number matches the exact electrical characteristics required for the design, as variations exist within the DG419 family. Cross-reference with authorized distributors to ensure authenticity and traceability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT switch with moderate speed and low on-resistance is required. Compare against the DG419DY-E3 for tube packaging alternatives or the DG419LEDY-T1-GE4 if lower voltage operation and reduced on-resistance are prioritized. Ensure the SOIC-8 footprint fits the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of enhanced analog switches from Vishay Siliconix. The series is characterized by improved operating voltage ranges and leakage limits compared to earlier generations. The DG419LDY-T1-E3 specifically targets applications requiring reliable switching in industrial environments with standard dual-supply configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG419LDY-E3 is listed as an alias for this part number. The DG419DY-E3 offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel. Verify pin compatibility before substitution.
