Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): DG417CY+ is the primary direct equivalent. It maintains all electrical specifications of the original DG417CY while offering active product status and RoHS3 compliance. This part is suitable for applications where the original 0°C ~ 70°C operating temperature range and 10V ~ 30V single supply voltage range are sufficient.

For Extended Temperature Range Applications: ADG417BRZ, ADG417BRZ-REEL, DG417DY-E3, and DG417DY-T1-E3 all provide -40°C ~ 85°C operating temperature range with active product status and RoHS3 compliance. These parts are appropriate for industrial and automotive environments requiring wider temperature operation.

For Lower On-State Resistance Requirements: DG417BDY-E3 and DG417BDY-T1-E3 offer 25Ohm on-state resistance (versus 35Ohm in the original), providing reduced signal path impedance. These parts are suitable for applications where lower insertion loss is critical. Extended temperature range (-40°C ~ 85°C) and RoHS3 compliance are included.

Packaging Considerations:

Tube packaging: DG417CY+, ADG417BRZ, DG417BDY-E3, DG417DY-E3
Tape & Reel (TR): ADG417BRZ-REEL, DG417BDY-T1-E3, DG417DY-T1-E3
Cut Tape & Digi-Reel: ADG417BRZ-REEL

All substitute parts are RoHS3 compliant, addressing the non-compliance status of the original DG417CY.

Frequently Asked Questions (FAQ)

Q: Can DG417CY+ be used as a direct replacement for DG417CY? A: Yes. DG417CY+ maintains identical electrical specifications including 35Ohm on-state resistance, 3pC charge injection, and 0°C ~ 70°C operating temperature. The primary difference is active product status and RoHS3 compliance.

Q: What is the difference between ADG417BRZ and DG417DY-E3? A: Both parts offer 35Ohm on-state resistance and identical switch timing (175ns, 145ns). The primary differences are manufacturer (Analog Devices vs. Vishay Siliconix) and charge injection (7pC vs. 60pC). ADG417BRZ is recommended by Analog Devices as the primary alternative.

Q: Why do DG417BDY variants have lower on-state resistance? A: DG417BDY-E3 and DG417BDY-T1-E3 are specified with 25Ohm on-state resistance instead of 35Ohm. This lower impedance reduces signal attenuation in switching applications. These parts are suitable only if the circuit design accommodates the different resistance value.

Q: What packaging options are available? A: Substitute parts are available in three packaging formats: Tube (standard), Tape & Reel (TR) for automated assembly, and Cut Tape & Digi-Reel for mixed-volume procurement. All maintain the 8-SOIC (0.154", 3.90mm Width) physical form factor.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry RoHS3 compliance certification, addressing the non-compliance status of the original DG417CY.

Q: Which substitute part offers the widest operating temperature range? A: ADG417BRZ, ADG417BRZ-REEL, DG417BDY-E3, DG417BDY-T1-E3, DG417DY-E3, and DG417DY-T1-E3 all operate across -40°C ~ 85°C, compared to the original 0°C ~ 70°C range.

Q: Can I use parts with different on-state resistance values interchangeably? A: No. On-state resistance directly affects signal path impedance and insertion loss. DG417BDY variants (25Ohm) and DG417DY variants (35Ohm) are not interchangeable without circuit redesign and verification.
