Substitute Part Grouping Explanation
Substitution of the DG411MY/PR is determined by strict equivalence across the following critical parameters:
- Switch Circuit Configuration: SPST-NC topology with 4 independent circuits
- On-State Resistance: 45Ohm maximum specification
- Channel Matching: ΔRon of 3Ohm maximum
- Supply Voltage Range: Compatibility with both single supply (10V ~ 30V) and dual supply (±4.5V ~ 20V) operation
- Package Type: 16-SOIC surface mount form factor
- Switching Performance: Ton/Toff specifications of 175ns/145ns maximum
- Electrical Isolation: Crosstalk performance at -85dB @ 1MHz
The DG411MY/PR+ qualifies as a direct substitute based on identical base product number (DG411), matching package specification (16-SOIC), and equivalent functional circuit topology. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations
The DG411MY/PR+ is the direct substitute for the obsolete DG411MY/PR. Both components share identical functional specifications, package geometry, and electrical performance characteristics. The DG411MY/PR+ offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the DG411MY/PR+ achieves ROHS3 compliance, addressing regulatory requirements for new designs and procurement in regions with RoHS mandates. Both parts maintain equivalent REACH and export classification status (EAR99).
For applications requiring the DG411MY/PR, transition to the DG411MY/PR+ is supported by matching electrical specifications and identical 16-SOIC packaging. No circuit redesign or board layout modification is necessary for this substitution.
Frequently Asked Questions (FAQ)
Q: Can the DG411MY/PR+ directly replace the DG411MY/PR in existing designs?
A: Yes. The DG411MY/PR+ is a direct pin-for-pin and functionally equivalent substitute. Both components feature identical 16-SOIC packaging, 4-circuit SPST-NC topology, and matching electrical specifications including 45Ohm on-state resistance and switching performance parameters.
Q: What is the primary difference between these two part numbers?
A: The DG411MY/PR is classified as obsolete, while the DG411MY/PR+ maintains active product status. The DG411MY/PR+ also achieves ROHS3 compliance, whereas the DG411MY/PR is RoHS non-compliant. Electrical performance and package specifications remain identical.
Q: Are there any package or pinout differences?
A: No. Both the DG411MY/PR and DG411MY/PR+ use the 16-SOIC surface mount package with identical pinout and mechanical dimensions (0.154" width, 3.90mm).
Q: Does the RoHS3 compliance of the DG411MY/PR+ affect circuit performance?
A: No. RoHS3 compliance reflects manufacturing process and material composition standards. Electrical characteristics, switching performance, and functional behavior remain unchanged.
Q: What supply voltage configurations are supported?
A: Both parts support single supply operation (10V ~ 30V) and dual supply operation (±4.5V ~ 20V), providing flexibility for various circuit topologies.
