DG417DY Equivalent & Substitute Parts

Part Overview

The DG417DY is a single-circuit SPST-NC (Normally Closed) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated in 8-SOIC surface mount packaging. This component operates as a 1:1 multiplexer/demultiplexer with 35Ohm on-state resistance and supports both single and dual supply voltage configurations. The DG417DY is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Active alternatives from both Analog Devices and Vishay Siliconix maintain functional compatibility while offering improved compliance status and performance characteristics.

Engineering Selection Recommendations

For Direct Replacement with Improved Compliance: DG417DY+ and DG417DY-T1-E3 are the primary substitutes, offering identical electrical specifications to the obsolete DG417DY while achieving RoHS3 compliance and active product status. These parts require no circuit redesign and maintain the same supply voltage ranges and switching characteristics. Selection between tube (DG417DY+) and tape & reel (DG417DY-T1-E3) packaging depends on procurement and assembly requirements.

For Enhanced Performance with Reduced On-State Resistance: DG417BDY-E3 and DG417BDY-T1-E3 provide 25Ohm on-state resistance with significantly faster switching times (89ns Ton, 80ns Toff). These Vishay Siliconix parts support extended voltage ranges (13V ~ 36V single supply, ±7V ~ 22V dual supply) and are RoHS3 compliant. Circuit validation is required to confirm compatibility with the reduced on-state resistance and modified charge injection characteristics.

For Analog Devices Active Portfolio Continuity: ADG417BRZ and ADG417BRZ-REEL maintain the 35Ohm on-state resistance specification with improved charge injection performance (7pC) and faster switching times (160ns Ton, 100ns Toff). These parts operate at fixed supply voltages (12V single, ±15V dual) and are RoHS3 compliant. Selection between tube (ADG417BRZ) and cut tape/digi-reel (ADG417BRZ-REEL) packaging accommodates different supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can DG417DY+ be used as a direct replacement for DG417DY? A: Yes. DG417DY+ maintains identical electrical specifications including on-state resistance (35Ohm), supply voltage ranges (10V ~ 30V single, ±4.5V ~ 20V dual), and switching times (175ns Ton, 145ns Toff). The primary differences are active product status and RoHS3 compliance. Packaging is tube format.

Q: What is the difference between DG417DY-T1-E3 and DG417DY+? A: Both parts are electrically identical with identical specifications. The primary difference is packaging: DG417DY-T1-E3 is supplied in tape & reel format for automated assembly, while DG417DY+ is supplied in tube format. Both are RoHS3 compliant and active products.

Q: Can DG417BDY-E3 replace DG417DY in all applications? A: DG417BDY-E3 is electrically compatible for SPST-NC switching applications but features reduced on-state resistance (25Ohm vs. 35Ohm), faster switching times (89ns vs. 175ns Ton), and different charge injection (38pC vs. 3pC). Circuit validation is required to confirm the reduced on-state resistance does not affect signal integrity or power dissipation in the target application. Supply voltage ranges differ: 13V ~ 36V single supply and ±7V ~ 22V dual supply.

Q: What are the supply voltage differences between substitute parts? A: DG417DY and DG417DY+ support 10V ~ 30V single supply and ±4.5V ~ 20V dual supply. DG417DY-T1-E3, DG417DY-E3, ADG417BRZ, and ADG417BRZ-REEL operate at fixed 12V single supply and ±15V dual supply. DG417BDY-E3 and DG417BDY-T1-E3 support 13V ~ 36V single supply and ±7V ~ 22V dual supply. Verify supply voltage compatibility before selection.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts listed (DG417DY+, DG417DY-T1-E3, DG417DY-E3, ADG417BRZ, ADG417BRZ-REEL, DG417BDY-E3, DG417BDY-T1-E3) are RoHS3 compliant. The original DG417DY is RoHS non-compliant.

Q: What packaging options are available for each substitute? A: DG417DY+ is supplied in tube format. DG417DY-T1-E3 and DG417BDY-T1-E3 are supplied in tape & reel format. DG417DY-E3 and DG417BDY-E3 are supplied in tube format. ADG417BRZ is supplied in tube format. ADG417BRZ-REEL is supplied in cut tape and digi-reel format. Select packaging based on assembly process requirements.

Q: Do all parts maintain the same 8-SOIC package dimensions? A: Yes. All substitute parts use 8-SOIC packaging with 0.154" (3.90mm) width. PCB layout and footprints are identical across all listed parts.

Q: What is the significance of charge injection differences? A: Charge injection affects signal settling time and noise in analog switching applications. DG417DY and DG417DY+ have the lowest charge injection (3pC). ADG417BRZ and ADG417BRZ-REEL have moderate charge injection (7pC). DG417BDY-E3 and DG417BDY-T1-E3 have higher charge injection (38pC), while DG417DY-T1-E3 and DG417DY-E3 have the highest (60pC). Applications sensitive to charge injection should prioritize lower values.
