Equivalent & Substitute Parts for DG413DY
Part Overview
The DG413DY is a 4-circuit SPST (Single Pole Single Throw) IC switch manufactured by Vishay Siliconix, housed in a 16-SOIC surface mount package. This interface component features 35Ohm on-state resistance and operates across a wide supply voltage range of 5V to 44V (single supply) or ±5V to ±20V (dual supply). The DG413DY is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Active alternatives with comparable or enhanced electrical characteristics are available from multiple manufacturers including Analog Devices Inc./Maxim Integrated and Renesas Electronics Corporation.

Substitute Part Grouping Explanation
Substitute parts for the DG413DY are categorized based on electrical compatibility and manufacturing status. The primary substitution criteria are:
Critical Parameters for Substitution:
- Switch circuit topology (SPST - NO/NC)
- Number of circuits (4)
- Package type (16-SOIC)
- On-state resistance compatibility
- Supply voltage range compatibility
- Operating temperature range
Substitution Categories:
Category 1: Direct Electrical Equivalents (35Ohm On-State Resistance) Parts maintaining the original 35Ohm on-state resistance specification: DG413DY-E3, DG413DYZ-T, DG413FDY+, and DG413FDY+T. These parts preserve the electrical performance of the original design and are suitable for direct replacement in applications where the 35Ohm specification is critical.
Category 2: Enhanced Performance Variants (45Ohm On-State Resistance) Parts with slightly higher on-state resistance (45Ohm) but expanded operating temperature range and improved channel-to-channel matching: DG413CY+, DG413CY+T, and DG413DY+, DG413DY+T. These are suitable for applications where the higher resistance is acceptable and extended temperature performance is beneficial.
Category 3: Low-Resistance Alternative (4Ohm On-State Resistance) The MAX4606CSE+ and MAX4606CSE+T offer significantly lower on-state resistance (4Ohm) with faster switching times, suitable for applications requiring minimal signal attenuation and improved bandwidth performance.

Engineering Selection Recommendations
For Direct Replacement (Electrical Equivalence): DG413DY-E3 is the primary direct substitute, maintaining identical electrical specifications while offering active product status and ROHS3 compliance. This part is recommended for applications requiring no design modification and is available in tube packaging with 1158 units in stock.
For Extended Temperature Range with Active Status: DG413DYZ-T (Renesas) and DG413FDY+ (Analog Devices) maintain the 35Ohm on-state resistance and -40°C to 85°C operating range. DG413FDY+ offers improved crosstalk performance (-105dB @ 1MHz versus -85dB) and enhanced channel-to-channel matching (200mOhm), making it suitable for noise-sensitive applications. Both are ROHS3 compliant and actively manufactured.
For Reduced Supply Voltage Sensitivity: DG413DY+ and DG413DY+T (Analog Devices) provide extended operating temperature coverage (-40°C to 85°C) with 45Ohm on-state resistance. These parts are suitable for applications where the slightly higher resistance is acceptable and where the narrower supply voltage range (10V ~ 30V single supply) aligns with system requirements.
For Low-Impedance Applications: MAX4606CSE+ and MAX4606CSE+T offer 4Ohm on-state resistance with faster switching times (120ns/130ns versus 175ns/145ns), suitable for applications requiring minimal signal attenuation. Operating temperature is limited to 0°C ~ 70°C, and supply voltage range is 4.5V ~ 36V (single supply).
Compliance Considerations: All substitute parts listed are ROHS3 compliant and REACH unaffected, addressing regulatory requirements not met by the original obsolete DG413DY. Selection should prioritize active product status to ensure long-term availability and manufacturing support.
Frequently Asked Questions (FAQ)
Q: Can DG413DY-E3 be used as a direct drop-in replacement for DG413DY? A: Yes. DG413DY-E3 maintains identical electrical specifications including 35Ohm on-state resistance, supply voltage ranges (5V ~ 44V single, ±5V ~ 20V dual), and operating temperature (-40°C ~ 85°C). The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant). Packaging differs (tube for DG413DY-E3), but the 16-SOIC footprint is identical.
Q: What is the difference between DG413FDY+ and DG413DY-E3? A: Both maintain 35Ohm on-state resistance and -40°C to 85°C operating temperature. DG413FDY+ offers superior crosstalk performance (-105dB @ 1MHz versus -85dB) and tighter channel-to-channel matching (200mOhm). However, DG413FDY+ has a narrower single supply voltage range (9V ~ 36V versus 5V ~ 44V) and dual supply range (±4.5V ~ 20V versus ±5V ~ 20V). Selection depends on whether the improved crosstalk justifies the reduced voltage range.
Q: Why do some substitutes have 45Ohm on-state resistance instead of 35Ohm? A: The 45Ohm variants (DG413CY+, DG413DY+) are manufactured by Analog Devices and represent a different product line within the DG413 family. The 10Ohm increase in on-state resistance is acceptable in many applications and may provide other benefits such as improved temperature stability or manufacturing consistency. Applications sensitive to signal attenuation should verify that 45Ohm resistance meets performance requirements.
Q: Is MAX4606CSE+ compatible with DG413DY? A: MAX4606CSE+ is functionally compatible (4-circuit SPST switch in 16-SOIC package) but offers significantly different electrical characteristics. The 4Ohm on-state resistance is substantially lower, providing reduced signal attenuation. However, operating temperature is limited to 0°C ~ 70°C (versus -40°C ~ 85°C), and charge injection is higher (225pC versus 5pC). Use MAX4606CSE+ only when low on-state resistance is required and the narrower temperature range is acceptable.
Q: What packaging options are available for substitutes? A: Substitute parts are available in three packaging formats: Tube (standard packaging), Tape & Reel (TR) for automated assembly, and Cut Tape (CT) & Digi-Reel® for mixed-volume production. Selection depends on manufacturing process requirements. Tube packaging is suitable for manual assembly or small-volume production. Tape & Reel and Cut Tape formats are optimized for high-volume automated pick-and-place assembly.
Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected. The original DG413DY is RoHS non-compliant, making compliance a key advantage of substitution for applications subject to RoHS regulations.
Q: What is the inventory status of substitute parts? A: DG413DY-E3 has 1158 units in stock. DG413DYZ-T (Renesas) has the highest inventory at 3900 units. DG413FDY+ and DG413FDY+T have 2330 and 1937 units respectively. DG413DY+ and DG413DY+T have 2002 and 2472 units. MAX4606CSE+ has 2230 units, and MAX4606CSE+T has 752 units. Inventory levels support both prototype and production-volume requirements.
