DG411HSAK-E3 Equivalent & Substitute Parts

Part Overview

The DG411HSAK-E3 is a 4-circuit IC switch with SPST-NC (Single Pole Single Throw - Normally Closed) configuration manufactured by Vishay Siliconix. This interface component operates across a wide supply voltage range (13V to 44V single supply, or ±5V to ±20V dual supply) and features 35Ohm on-state resistance with fast switching characteristics. The part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution for the DG411HSAK-E3 is determined by the following critical parameters:

Switch Configuration: SPST-NC topology with 4 circuits in 1:1 multiplexer configuration
On-State Resistance: Maximum 35Ohm (allows substitutes with equal or lower resistance)
Supply Voltage Compatibility: Single supply 13V to 44V or dual supply ±5V to ±20V
Package Type: 16-pin DIP format with 0.300" (7.62mm) pitch
Operating Temperature Range: -55°C to 125°C
Electrical Performance: Switching speed, charge injection, capacitance, and leakage current characteristics

The three substitute parts listed maintain the core SPST-NC 4-circuit architecture and are pin-compatible within the DG411 base product family. Substitution feasibility depends on whether the application can accommodate differences in switching speed, charge injection, and supply voltage minimums.

Engineering Selection Recommendations

DG411AK: This Vishay Siliconix substitute maintains identical on-state resistance (35Ohm) and package format. It extends the single supply voltage range to 5V minimum (versus 13V for the DG411HSAK-E3), providing greater flexibility for lower-voltage applications. However, switching times are slower (175ns/145ns versus 105ns/80ns), and the part is RoHS non-compliant. Product status is obsolete, limiting long-term availability.

DG411AK/883B: Manufactured by Analog Devices Inc./Maxim Integrated, this part offers the lowest on-state resistance (30Ohm) among the substitutes and is the only active product in this group. It carries ROHS3 compliance and is supplied in tube packaging. The supply voltage range is narrower (10V to 30V single supply, ±4.5V to ±20V dual supply), which may restrict use in applications requiring the full 13V to 44V range of the original part. Switching times match the DG411AK at 175ns/145ns.

DG411DJZ: Manufactured by Renesas Electronics Corporation, this substitute maintains the 35Ohm on-state resistance and extends single supply voltage compatibility to 5V minimum. It is an active product with ROHS3 compliance and offers the lowest leakage current (100pA versus 250pA). The operating temperature range is narrower (-40°C to 85°C versus -55°C to 125°C), which may be limiting for extended temperature applications. Package designation is 16-DIP (PDIP) rather than CDIP, though both maintain 0.300" (7.62mm) pitch.

For applications requiring RoHS3 compliance and active product status, DG411AK/883B or DG411DJZ are preferred. For applications requiring the full temperature range (-55°C to 125°C), DG411AK/883B is the only substitute that maintains this specification. For applications requiring the full supply voltage range (13V to 44V single supply), DG411AK or DG411DJZ are suitable.

Frequently Asked Questions (FAQ)

Q: Can DG411AK/883B replace DG411HSAK-E3 in all applications?

A: DG411AK/883B is functionally compatible for SPST-NC 4-circuit switching applications with identical pin configuration. However, the single supply voltage range is limited to 10V to 30V, which excludes applications requiring operation below 10V or above 30V. The full -55°C to 125°C temperature range is maintained. Applications operating within these voltage and temperature constraints can use this substitute without modification.

Q: What is the difference between 16-CDIP and 16-DIP (PDIP) packages?

A: Both packages maintain 0.300" (7.62mm) pitch and 16-pin configuration, making them mechanically compatible for through-hole mounting. CDIP (Ceramic DIP) and PDIP (Plastic DIP) differ in substrate material and thermal characteristics. Component placement and PCB footprints designed for one package type will accommodate the other without modification.

Q: Why does DG411HSAK-E3 have faster switching times than the substitutes?

A: The DG411HSAK-E3 specifies maximum switch times of 105ns (Ton) and 80ns (Toff), while all three substitutes specify 175ns and 145ns respectively. This difference reflects different semiconductor process generations and design optimization. Applications sensitive to switching speed must account for this 70ns increase in turn-on time and 65ns increase in turn-off time.

Q: Is RoHS compliance a critical factor for substitution?

A: RoHS compliance depends on application requirements and regulatory jurisdiction. DG411AK is RoHS non-compliant, while DG411AK/883B and DG411DJZ are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, only DG411AK/883B or DG411DJZ are acceptable substitutes.

Q: Can DG411DJZ be used in applications requiring -55°C operation?

A: No. DG411DJZ specifies an operating temperature range of -40°C to 85°C, which does not include -55°C. Applications requiring operation at -55°C must use DG411AK/883B, which maintains the full -55°C to 125°C range of the original DG411HSAK-E3.

Q: What is the significance of lower charge injection in the substitute parts?

A: Charge injection (22pC for DG411HSAK-E3 versus 5pC for all substitutes) represents the charge transferred to the signal path during switching transitions. Lower charge injection reduces signal distortion in precision analog switching applications. All three substitutes offer superior charge injection performance, making them suitable for applications where signal fidelity is critical.
