DG413DY Equivalent & Substitute Parts

Part Overview

The DG413DY is a 4-circuit SPST-NO/NC analog switch IC manufactured by Analog Devices Inc./Maxim Integrated in 16-SOIC surface mount packaging. This component operates as a 1:1 multiplexer/demultiplexer with 45Ohm on-state resistance and supports dual supply voltages (±4.5V to ±20V) or single supply (10V to 30V). The DG413DY is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Active alternatives from Analog Devices and third-party manufacturers provide improved specifications, enhanced compliance, and continued availability.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): DG413DY+ is the primary direct equivalent, offering identical on-state resistance (45Ohm), channel matching (3Ohm max), and switching characteristics. The key advantage is active product status and ROHS3 compliance, addressing the obsolescence and regulatory limitations of the original DG413DY. Tube packaging matches the original specification.

For Improved Performance with Supply Voltage Constraints: ADG413BRZ and ADG413BRZ-REEL reduce on-state resistance to 35Ohm while maintaining identical switching times and crosstalk performance. These parts require fixed supply voltages (12V single or ±15V dual) compared to the DG413DY's wider range. Both are ROHS3 compliant and active. Choose the REEL variant for automated assembly processes.

For Enhanced Speed and Matching: ADG433BRZ and ADG433BRZ-REEL offer 24Ohm on-state resistance with superior channel matching (1.2Ohm) and significantly faster switching (90ns/60ns vs. 175ns/145ns). These parts are suitable for applications prioritizing speed and signal integrity. Supply voltage requirements match ADG413BRZ specifications. REEL packaging available for high-volume production.

For Ultra-Low Impedance Applications: ADG453BRZ, ADG453BRZ-REEL, and ADG453BRZ-REEL7 provide 5Ohm on-state resistance with exceptional channel matching (100mOhm) and improved crosstalk (-90dB). These parts support the DG413DY's dual supply range (±4.5V ~ 20V) while requiring 12V single supply. Higher charge injection (20pC) and capacitance (37pF) must be evaluated against application requirements. Multiple packaging options available.

For Cross-Manufacturer Sourcing: DG213DY-E3 and DG213DY-T1-E3 from Vishay Siliconix provide 60Ohm on-state resistance with superior charge injection (1pC) and improved crosstalk (-95dB @ 100kHz). These parts support higher supply voltage ranges (13V ~ 36V single, ±7V ~ 22V dual) and faster switching times (130ns/100ns). Both are ROHS3 compliant and active. Packaging options include Tube and Cut Tape & Digi-Reel variants.

Compliance and Availability: All recommended substitutes are ROHS3 compliant and carry active product status, ensuring long-term availability and regulatory compliance. The DG413DY's RoHS non-compliance and obsolete status make migration to any active alternative necessary for new designs and future production runs.

Frequently Asked Questions (FAQ)

Q: Can DG413DY+ be used as a direct drop-in replacement for DG413DY? A: Yes. DG413DY+ maintains identical electrical specifications including 45Ohm on-state resistance, 3Ohm channel matching, switching times (175ns/145ns), and supply voltage ranges (10V ~ 30V single, ±4.5V ~ 20V dual). The 16-SOIC package and pinout are identical. The primary differences are active product status and ROHS3 compliance.

Q: What are the supply voltage constraints when substituting with ADG413BRZ or ADG433BRZ? A: ADG413BRZ and ADG433BRZ require fixed supply voltages: 12V for single supply or ±15V for dual supply. The DG413DY supports wider ranges (10V ~ 30V single, ±4.5V ~ 20V dual). Verify your circuit's supply voltages before selecting these alternatives. If your design requires the DG413DY's wider voltage range, use DG413DY+, ADG453BRZ variants, or DG213DY alternatives.

Q: How does on-state resistance affect circuit performance? A: On-state resistance directly impacts signal attenuation and power dissipation. Lower resistance (5Ohm for ADG453 vs. 45Ohm for DG413DY) reduces signal loss and heat generation, beneficial for low-level signal switching. Higher resistance (60Ohm for DG213DY) may be acceptable in applications with higher signal levels or where cost is prioritized. Verify your application's impedance requirements and signal levels before selecting a substitute.

Q: What is the difference between Tube and Cut Tape & Digi-Reel packaging? A: Tube packaging is suitable for manual assembly and small-volume production. Cut Tape & Digi-Reel packaging is designed for automated pick-and-place assembly systems and high-volume manufacturing. Both contain identical components; packaging choice depends on production methodology and volume requirements.

Q: Can ADG453BRZ be used if my circuit requires the DG413DY's ±4.5V ~ ±20V dual supply range? A: Yes. ADG453BRZ supports ±4.5V ~ ±20V dual supply operation, matching the DG413DY's range. However, ADG453BRZ requires 12V for single supply operation (vs. DG413DY's 10V ~ 30V range). Verify your specific supply configuration before selection.

Q: What is charge injection and why does it vary across substitutes? A: Charge injection is the amount of charge transferred to the signal path when the switch transitions. DG413DY and most ADG alternatives exhibit 5pC charge injection, while ADG453 variants show 20pC and DG213DY shows 1pC. Higher charge injection can introduce transient errors in precision analog circuits. Select based on your application's sensitivity to switching transients.

Q: Are all recommended substitutes pin-compatible with DG413DY? A: Yes. All substitutes maintain the 16-SOIC package form factor and identical pinout, enabling direct PCB footprint compatibility. However, verify supply voltage requirements and electrical specifications for your specific application before substitution.

Q: What is the significance of RoHS3 compliance? A: ROHS3 compliance indicates the component meets current European Union Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. The DG413DY's RoHS non-compliance may prevent use in regulated markets or with customers requiring RoHS-compliant components. All active substitutes are ROHS3 compliant.
