MAX351EPE Equivalent & Substitute Parts

Part Overview

The MAX351EPE is a 4-circuit SPST-NC (Single Pole Single Throw - Normally Closed) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This component features 35Ohm on-state resistance and operates across a wide supply voltage range (10V ~ 30V single supply or ±4.5V ~ 20V dual supply). The MAX351EPE is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute components must maintain functional compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX351EPE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Switch circuit configuration: SPST - NC
• Number of circuits: 4
• Multiplexer/Demultiplexer circuit: 1:1
• Package / Case: 16-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Operating temperature range: -40°C ~ 85°C (TA)

Secondary Compatibility Criteria:

• On-state resistance (Max): 35Ohm or lower
• Switch time (Ton, Toff): 175ns and 145ns or faster
• Charge injection: 5pC or lower
• Channel capacitance: 9pF or lower
• Current leakage (IS(off)): 250pA or lower
• Crosstalk: -85dB @ 1MHz or better

Supply Voltage Compatibility: Substitute parts must support the application's required supply voltage range. The MAX351EPE operates at 10V ~ 30V (single) or ±4.5V ~ 20V (dual). Substitute parts with broader or equivalent voltage ranges are acceptable.

Three substitute parts meet these criteria with active product status and current manufacturing compliance.

Engineering Selection Recommendations

ADG411BNZ (Analog Devices Inc.)

The ADG411BNZ provides direct functional equivalence to the MAX351EPE with identical on-state resistance (35Ohm), switch timing (175ns, 145ns), and electrical characteristics. This part is manufactured by Analog Devices Inc. and maintains active product status. The ADG411BNZ is ROHS3 compliant, addressing the non-compliance status of the obsolete MAX351EPE. Supply voltage specifications differ: ADG411BNZ operates at 12V (single) or ±15V (dual), which may require circuit verification for applications requiring the full 10V ~ 30V range of the original part.

ADG431BNZ (Analog Devices Inc.)

The ADG431BNZ offers improved performance characteristics with lower on-state resistance (24Ohm versus 35Ohm) and faster switch timing (90ns/60ns versus 175ns/145ns). Channel-to-channel matching is superior (1.2Ohm versus 2Ohm). This part is manufactured by Analog Devices Inc. with active product status and ROHS3 compliance. The ADG431BNZ operates at 12V (single) or ±15V (dual). Selection of this part is appropriate for applications where lower on-state resistance and faster switching are beneficial or required.

DG411DJ-E3 (Vishay Siliconix)

The DG411DJ-E3 provides functional equivalence with identical on-state resistance (35Ohm) and switch timing (175ns, 145ns). This part is manufactured by Vishay Siliconix with active product status and ROHS3 compliance. The DG411DJ-E3 offers the broadest supply voltage range (5V ~ 44V single, ±5V ~ 20V dual), providing maximum flexibility for applications with varying supply requirements. This part is suitable for designs requiring extended voltage range compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ADG411BNZ replace the MAX351EPE in all applications?

A: The ADG411BNZ is functionally equivalent for applications operating within its specified supply voltage range (12V single or ±15V dual). Applications requiring the full 10V ~ 30V range of the MAX351EPE must verify that the ADG411BNZ voltage specifications are compatible with the circuit design. All other electrical parameters (on-state resistance, switch timing, leakage current, crosstalk) are identical.

Q: What is the advantage of selecting the ADG431BNZ over the ADG411BNZ?

A: The ADG431BNZ provides lower on-state resistance (24Ohm versus 35Ohm) and faster switch timing (90ns/60ns versus 175ns/145ns). These improvements reduce signal distortion and enable faster switching applications. Selection depends on whether the application benefits from these enhanced characteristics.

Q: Are all substitute parts pin-compatible with the MAX351EPE?

A: All substitute parts use the 16-DIP (0.300", 7.62mm) package with through-hole mounting. Pin compatibility must be verified against the specific pinout diagram for each part, as internal circuit topology may differ between manufacturers.

Q: What is the impact of RoHS compliance on part selection?

A: The MAX351EPE is RoHS non-compliant. All substitute parts (ADG411BNZ, ADG431BNZ, DG411DJ-E3) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, selection of a compliant substitute part is necessary.

Q: Which substitute part offers the broadest supply voltage compatibility?

A: The DG411DJ-E3 (Vishay Siliconix) operates across 5V ~ 44V (single supply) or ±5V ~ 20V (dual supply), providing the widest voltage range. This part is optimal for applications with variable or extended supply voltage requirements.

Q: Can these parts be used interchangeably in existing MAX351EPE designs?

A: Electrical interchangeability is confirmed for all three substitute parts within their specified operating parameters. Physical interchangeability is confirmed for all parts (16-DIP package, through-hole mounting). Circuit verification is required to confirm supply voltage compatibility and to validate that improved performance characteristics (in the case of ADG431BNZ) do not introduce unintended effects in the application.
