DG413LDY Equivalent & Substitute Parts

Part Overview

The DG413LDY is a 4-circuit SPST-NO/NC analog switch IC manufactured by Vishay Siliconix in 16-SOIC surface mount packaging. This device operates across single supply (2.7V to 12V) and dual supply (±3V to ±6V) configurations with a maximum on-state resistance of 17Ohm and switching times of 19ns (Ton) and 12ns (Toff). The DG413LDY is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Active alternatives from Analog Devices Inc. provide enhanced compliance, improved performance characteristics, and extended availability.

Substitute Part Grouping Explanation

Substitution of the DG413LDY is determined by the following critical parameters: switch circuit topology (SPST - NO/NC), number of circuits (4), package type (16-SOIC), mounting method (surface mount), and operating temperature range (-40°C ~ 85°C). On-state resistance, supply voltage ranges, switching times, and leakage current are secondary selection criteria that define performance compatibility within application-specific requirements.

Substitute parts are grouped into three categories based on on-state resistance performance:

Low Resistance Group (5Ohm): ADG453BRZ, ADG453BRZ-REEL, ADG453BRZ-REEL7 — optimized for applications requiring minimal signal attenuation and lowest on-state resistance.

Medium Resistance Group (24Ohm - 35Ohm): ADG413BRZ, ADG413BRZ-REEL, ADG433BRZ, ADG433BRZ-REEL — balanced performance across voltage supply ranges and switching characteristics.

High Resistance Group (45Ohm): DG413CY+, DG413DY+, DG413DY+T — extended supply voltage range (10V ~ 30V) with higher on-state resistance suitable for specific circuit topologies.

All substitute parts maintain the 16-SOIC package footprint, SPST - NO/NC switch circuit configuration, 4-circuit count, and surface mount compatibility. All active substitutes comply with ROHS3 and maintain REACH Unaffected status.

Engineering Selection Recommendations

For Direct Performance Replacement: ADG433BRZ or ADG433BRZ-REEL provide the closest performance match to the DG413LDY with 24Ohm on-state resistance, reduced switching times (90ns Ton, 60ns Toff), and active product status with ROHS3 compliance. These parts maintain the same leakage current specification (250pA) and crosstalk performance (-85dB @ 1MHz) while supporting the extended dual supply range (±15V).

For Low-Resistance Applications: ADG453BRZ, ADG453BRZ-REEL, or ADG453BRZ-REEL7 deliver the lowest on-state resistance (5Ohm) with extended dual supply capability (±4.5V ~ 20V). These parts are suitable for applications prioritizing minimal signal attenuation, though they exhibit higher channel capacitance (37pF) and leakage current (500pA) compared to the DG413LDY.

For Extended Supply Voltage Range: DG413DY+ or DG413DY+T support the widest single supply voltage range (10V ~ 30V) with 45Ohm on-state resistance and full temperature range operation (-40°C ~ 85°C). DG413CY+ provides identical electrical characteristics but operates within a reduced temperature range (0°C ~ 70°C).

Compliance Consideration: All active substitute parts comply with ROHS3 and REACH Unaffected status, addressing regulatory requirements that the obsolete DG413LDY does not meet.

Frequently Asked Questions (FAQ)

Q: Can ADG453BRZ directly replace DG413LDY in all applications?

A: ADG453BRZ maintains the same 16-SOIC package, SPST - NO/NC circuit topology, and 4-circuit configuration. However, the 5Ohm on-state resistance differs from the DG413LDY's 17Ohm specification. Substitution is valid only if the application tolerates lower on-state resistance and higher channel capacitance (37pF vs. 5pF/6pF). Verify supply voltage compatibility: ADG453BRZ supports ±4.5V ~ 20V dual supply, while DG413LDY supports ±3V ~ 6V.

Q: What is the difference between ADG413BRZ and ADG433BRZ?

A: Both parts share identical supply voltage ranges (12V single, ±15V dual) and package specifications. ADG433BRZ offers superior switching performance with 24Ohm on-state resistance and faster switching times (90ns Ton, 60ns Toff) compared to ADG413BRZ (35Ohm, 175ns Ton, 145ns Toff). ADG433BRZ also specifies channel-to-channel matching (ΔRon = 1.2Ohm), providing tighter performance consistency across circuits.

Q: Are packaging variants (Tube vs. Cut Tape & Digi-Reel) electrically equivalent?

A: Yes. ADG413BRZ (Tube) and ADG413BRZ-REEL (Cut Tape & Digi-Reel) are electrically identical. Packaging differences affect only supply chain logistics and handling. ADG453BRZ-REEL7 is a specific Digi-Reel variant of ADG453BRZ with identical electrical specifications.

Q: Why does DG413CY+ have a reduced operating temperature range?

A: DG413CY+ operates within 0°C ~ 70°C, compared to the full industrial range (-40°C ~ 85°C) of DG413DY+ and DG413DY+T. Select DG413CY+ only for applications with ambient temperature constraints within this narrower range. For full temperature coverage, use DG413DY+ or DG413DY+T.

Q: What is the significance of the "+T" suffix in DG413DY+T?

A: The "+T" suffix indicates Cut Tape & Digi-Reel packaging, while DG413DY+ uses Tube packaging. Electrical specifications are identical; the suffix denotes packaging and delivery format only.

Q: Can I use DG413DY+ in place of DG413LDY for low-voltage applications?

A: DG413DY+ supports single supply from 10V ~ 30V and dual supply ±4.5V ~ 20V. The DG413LDY supports lower single supply (2.7V ~ 12V) and lower dual supply (±3V ~ 6V). DG413DY+ is not suitable for applications requiring operation below 10V single supply or ±4.5V dual supply. Verify your circuit's minimum supply voltage requirement before substitution.

Q: How do crosstalk specifications affect substitution?

A: The DG413LDY specifies -95dB crosstalk @ 1MHz, while all active substitutes specify -85dB @ 1MHz. This 10dB difference indicates slightly higher signal coupling between channels in substitute parts. For applications with stringent crosstalk requirements (audio, precision instrumentation), evaluate whether the -85dB specification meets system performance targets. Most general-purpose switching applications tolerate this difference.
