DG401DVZ Equivalent & Substitute Parts

Part Overview

The DG401DVZ is a 2-circuit IC switch manufactured by Renesas Electronics Corporation, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with 45Ohm on-state resistance. This component is designed for analog signal switching applications requiring low on-resistance and fast switching performance. The DG401DVZ is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution of the DG401DVZ is determined by strict equivalence across the following critical parameters:

Switch Circuit Configuration: SPST - NO topology
Circuit Count: 2 circuits
Multiplexer/Demultiplexer Ratio: 1:1
On-State Resistance: 45Ohm maximum
Channel-to-Channel Matching: 3Ohm maximum
Supply Voltage Range: 5V ~ 34V (single) or ±5V ~ 17V (dual)
Switching Performance: Ton/Toff specifications of 150ns/100ns maximum
Electrical Characteristics: Charge injection, capacitance, leakage current, and crosstalk parameters
Operating Temperature Range: -40°C ~ 85°C
Compliance Standards: RoHS3 compliance and REACH unaffected status

The DG401DYZ qualifies as a direct functional substitute based on identical electrical specifications across all critical parameters. The primary difference is packaging format: DG401DVZ uses 16-TSSOP while DG401DYZ uses 16-SOIC. Both packages are surface-mount configurations with compatible pinouts for the DG401 base product family.

Engineering Selection Recommendations

The DG401DYZ is electrically equivalent to the DG401DVZ across all functional parameters. Both devices maintain identical electrical specifications for switching performance, impedance characteristics, and signal integrity metrics. Both components are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

The primary consideration for selection is packaging format. The DG401DVZ uses 16-TSSOP packaging (4.40mm width), while the DG401DYZ uses 16-SOIC packaging (3.90mm width). PCB layout and footprint compatibility must be evaluated based on the specific application design. The DG401DYZ has a higher moisture sensitivity level (MSL 3, 168 hours) compared to the DG401DVZ (MSL 1, unlimited), which may impact storage and handling requirements in high-humidity environments.

Frequently Asked Questions (FAQ)

Q: Can DG401DYZ replace DG401DVZ in existing designs?

A: Yes, provided the PCB footprint accommodates the 16-SOIC package format. All electrical specifications are identical. The pinout configuration for the DG401 base product family is compatible between these package variants.

Q: What is the primary difference between DG401DVZ and DG401DYZ?

A: The packages differ: DG401DVZ uses 16-TSSOP (0.173", 4.40mm width) while DG401DYZ uses 16-SOIC (0.154", 3.90mm width). Electrical performance is identical.

Q: Are there moisture sensitivity considerations when substituting?

A: Yes. DG401DVZ has MSL 1 (unlimited moisture exposure), while DG401DYZ has MSL 3 (168-hour limit). Applications requiring extended storage in high-humidity conditions should account for this difference in handling procedures.

Q: Do both parts meet current compliance standards?

A: Yes. Both DG401DVZ and DG401DYZ are RoHS3 compliant and REACH unaffected.

Q: What supply voltage ranges are supported?

A: Both parts support single supply operation from 5V to 34V, or dual supply operation from ±5V to ±17V.

Q: Are the switching characteristics identical?

A: Yes. Both parts have identical maximum switch times (Ton 150ns, Toff 100ns), charge injection (60pC), and crosstalk performance (-90dB @ 1MHz).
