DG417BAK-E3 Equivalent & Substitute Parts

Part Overview

The DG417BAK-E3 is a single-circuit SPST-NC (Normally Closed) analog switch IC manufactured by Vishay Siliconix, housed in an 8-CERDIP package. This component operates as a 1:1 multiplexer/demultiplexer with 35Ohm on-state resistance and supports dual supply voltages (±7V to ±22V) or single supply (13V to 36V). The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence in switching performance, electrical characteristics, and package compatibility while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DG417BAK-E3 is determined by the following critical parameters:

Primary Substitution Criteria:

• Switch circuit type: SPST - NC
• Multiplexer/demultiplexer configuration: 1:1
• Number of circuits: 1
• On-state resistance: 35Ohm maximum
• Current leakage: 250pA maximum
• Package compatibility: Through-hole mounting with 8-pin DIP or CERDIP footprint (0.300", 7.62mm pitch)
• RoHS3 compliance and MSL Level 1

Secondary Compatibility Factors:

• Supply voltage ranges must encompass or be compatible with application requirements
• Switch timing characteristics (Ton, Toff) must be acceptable for the intended switching frequency
• Charge injection and channel capacitance values must not degrade signal integrity in the target application
• Operating temperature range must cover the deployment environment

Two substitute parts meet these criteria with varying performance trade-offs and product status classifications.

Engineering Selection Recommendations

ADG417BNZ (Analog Devices Inc.)

The ADG417BNZ is an active-status substitute with full functional equivalence in core switching parameters. It maintains 35Ohm on-state resistance, 1:1 multiplexer configuration, and SPST-NC circuit topology. The part is ROHS3 compliant with MSL Level 1 rating. Primary considerations include single supply voltage specification (12V) versus the DG417BAK-E3's 13V–36V range, and dual supply limited to ±15V versus ±7V–±22V. Switch timing is slower (160ns/100ns versus 62ns/53ns), with significantly reduced charge injection (7pC versus 38pC) and lower channel capacitance (6pF versus 12pF). The 8-DIP package maintains mechanical compatibility with 0.300" pitch. This substitute is suitable for applications where the narrower supply voltage range and slower switching speed are acceptable trade-offs for improved signal integrity characteristics.

DG417AK/883B (Analog Devices Inc./Maxim Integrated)

The DG417AK/883B is an active-status substitute with identical package form factor (8-CERDIP) to the main part. It maintains 35Ohm on-state resistance and SPST-NC configuration. Supply voltage ranges (10V–30V single, ±4.5V–±20V dual) provide broader compatibility than ADG417BNZ while remaining narrower than the original DG417BAK-E3. Switch timing is slower (175ns/145ns), with superior charge injection (3pC) and channel capacitance (8pF) performance. The part includes channel-to-channel matching specification (3Ohm max) and crosstalk performance (-85dB @ 1MHz). Operating temperature range (0°C–70°C) is narrower than the original. ROHS3 compliance and MSL Level 1 certification are maintained. This substitute is optimal for applications requiring package-level compatibility and enhanced signal integrity in moderate-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can ADG417BNZ replace DG417BAK-E3 in all applications?

A: ADG417BNZ maintains functional equivalence in core switching parameters (SPST-NC, 1:1 configuration, 35Ohm on-state resistance, 250pA leakage). However, supply voltage specifications differ: ADG417BNZ operates at 12V single supply and ±15V dual supply, while DG417BAK-E3 supports 13V–36V single and ±7V–±22V dual. Applications requiring the full voltage range of the original part may require circuit redesign. Switch timing is slower (160ns/100ns versus 62ns/53ns), which may impact high-frequency switching applications.

Q: What are the package differences between ADG417BNZ and DG417AK/883B?

A: ADG417BNZ uses 8-DIP (0.300", 7.62mm) packaging, while DG417AK/883B uses 8-CERDIP (0.300", 7.62mm) packaging. Both maintain identical 0.300" pitch and through-hole mounting compatibility. The CERDIP package (ceramic DIP) of DG417AK/883B matches the original DG417BAK-E3 form factor exactly, while the DIP package of ADG417BNZ uses plastic construction. For PCB layouts designed specifically for CERDIP footprints, DG417AK/883B provides direct mechanical compatibility.

Q: Which substitute offers better signal integrity?

A: DG417AK/883B provides superior signal integrity characteristics with charge injection of 3pC (versus 38pC in the original and 7pC in ADG417BNZ) and channel capacitance of 8pF (versus 12pF in the original and 6pF in ADG417BNZ). DG417AK/883B also specifies crosstalk performance (-85dB @ 1MHz), which is not provided for the other parts. These characteristics make DG417AK/883B preferable for precision analog switching applications where signal fidelity is critical.

Q: Are both substitutes RoHS3 compliant?

A: Yes. Both ADG417BNZ and DG417AK/883B are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the obsolete DG417BAK-E3.

Q: What is the operating temperature consideration for each substitute?

A: DG417BAK-E3 operates across -55°C to 125°C. ADG417BNZ operates -40°C to 85°C, and DG417AK/883B operates 0°C to 70°C. Applications requiring the full -55°C to 125°C range of the original part cannot use either substitute without thermal management modifications or circuit redesign.
