DG411C/D Equivalent & Substitute Parts
Part Overview
The DG411C/D is a 4-circuit IC switch with SPST-NC (Single Pole Single Throw - Normally Closed) configuration manufactured by Analog Devices Inc./Maxim Integrated. This die-packaged component operates across a wide supply voltage range and is designed for precision switching applications requiring low on-state resistance and minimal crosstalk.
The DG411C/D is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for systems utilizing this interface component.

Substitute Part Grouping Explanation
Substitution of the DG411C/D is determined by the following critical parameters:
- Switch Circuit Configuration: Must be SPST - NC (4 circuits, 1:1 multiplexer/demultiplexer)
- On-State Resistance: The substitute must support the application's resistance tolerance requirements
- Supply Voltage Range: The substitute must operate within or encompass the required voltage specifications
- Switching Performance: Switch time, charge injection, and crosstalk characteristics must meet application demands
- Leakage Current: Maximum leakage specifications must not exceed application limits
- Thermal Operating Range: Must support -40°C ~ 85°C operation
- Compliance: RoHS3 compliance and REACH unaffected status required
- Package Compatibility: Physical form factor and mounting type must be compatible with the application
The DG411DY+ is identified as a manufacturer-recommended substitute. While it maintains the same base product number (DG411), circuit configuration, and core electrical characteristics, it differs in packaging format (16-SOIC vs. Die) and specific parameter tolerances.

Engineering Selection Recommendations
Product Status Consideration: The DG411C/D is obsolete, while the DG411DY+ is active. The DG411DY+ maintains manufacturer support, ongoing availability, and current compliance certifications.
Compliance Alignment: Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for new designs and production continuity.
Parameter Trade-offs: The DG411DY+ exhibits higher on-state resistance (45Ohm vs. 35Ohm) and reduced channel-to-channel matching tolerance (3Ohm vs. 100mOhm). Applications requiring the original 35Ohm specification or tighter matching tolerances must evaluate whether the DG411DY+ performance envelope is acceptable. The DG411DY+ also operates within a narrower supply voltage range (10V ~ 30V single supply vs. 13V ~ 44V), which may restrict applicability in systems requiring extended voltage operation.
Leakage Current: The DG411DY+ demonstrates superior leakage performance (250pA vs. 150nA), which may provide advantages in low-power or precision analog applications.
Package Transition: Substitution requires transition from die packaging to 16-SOIC surface mount packaging, necessitating PCB layout and assembly process modifications.
Frequently Asked Questions (FAQ)
Q: Can the DG411DY+ directly replace the DG411C/D in all applications?
A: Direct replacement depends on application-specific requirements. The DG411DY+ maintains identical switch circuit configuration, switching performance, and thermal operating range. However, the higher on-state resistance (45Ohm vs. 35Ohm) and reduced matching tolerance (3Ohm vs. 100mOhm) may impact applications with strict resistance specifications. The narrower supply voltage range (10V ~ 30V vs. 13V ~ 44V) must be verified against system requirements. Package transition from die to 16-SOIC requires PCB redesign.
Q: What are the key electrical differences between these parts?
A: Primary differences include on-state resistance (35Ohm vs. 45Ohm), channel-to-channel matching tolerance (100mOhm vs. 3Ohm), supply voltage operating ranges, and leakage current (150nA vs. 250pA). Switching time, charge injection, channel capacitance, and crosstalk specifications are identical.
Q: Does the package change affect circuit performance?
A: The transition from die to 16-SOIC packaging changes the physical form factor and mounting method. This requires PCB layout modifications and may introduce different parasitic characteristics depending on board design. The electrical performance of the IC itself remains consistent with the 16-SOIC package specification.
Q: Are both parts compliant with current regulatory standards?
A: Yes. Both the DG411C/D and DG411DY+ are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
Q: What supply voltage range should I verify for substitution?
A: The DG411C/D operates at 13V ~ 44V (single supply) or ±7V ~ 22V (dual supply). The DG411DY+ operates at 10V ~ 30V (single supply) or ±4.5V ~ 20V (dual supply). Verify that your system voltage requirements fall within the DG411DY+ range before substitution.
