Substitute Part Grouping Explanation

Substitution of the MAX317EPA is determined by strict equivalence across the following critical parameters:

Switch Circuit Configuration: Must be SPST - NC
Number of Circuits: Must be 1
On-State Resistance (Max): Must be 35Ohm
Package / Case: Must be 8-DIP (0.300", 7.62mm)
Mounting Type: Must be Through Hole
Operating Temperature Range: Must support -40°C ~ 85°C (TA)

Substitute parts are grouped into two categories:

Direct Variant: MAX317EPA+ maintains identical electrical specifications and package configuration as the main part, with the primary distinction being improved RoHS3 compliance status.

Manufacturer-Recommended Alternatives: ADG417BNZ (Analog Devices Inc.) and DG417DJ-E3 (Vishay Siliconix) are active-status components that meet the core substitution criteria while offering enhanced product lifecycle support and compliance certifications.

Engineering Selection Recommendations

MAX317EPA+ serves as the direct replacement for MAX317EPA applications where component availability from the original manufacturer is prioritized. Both parts share identical electrical specifications and package configuration. The MAX317EPA+ offers improved regulatory compliance through ROHS3 certification while maintaining obsolete product status.

ADG417BNZ is recommended for new designs and long-term production requirements. As an active-status component from Analog Devices Inc., it provides assured supply chain continuity and ROHS3 compliance. The ADG417BNZ demonstrates faster turn-off time (100ns versus 145ns) and lower charge injection (7pC versus 3pC), with supply voltage specifications limited to 12V single supply and ±15V dual supply configurations.

DG417DJ-E3 is recommended as an alternative from Vishay Siliconix for applications requiring active product lifecycle support and multi-source component strategies. This part maintains identical switch timing characteristics (175ns, 145ns) and channel capacitance (8pF, 8pF) as the original MAX317EPA, with the trade-off of significantly higher charge injection (60pC). Supply voltage specifications are identical to ADG417BNZ (12V single supply, ±15V dual supply).

Selection between ADG417BNZ and DG417DJ-E3 depends on charge injection sensitivity and supply voltage requirements within the specified operating ranges.

Frequently Asked Questions (FAQ)

Q: Can MAX317EPA be directly replaced with MAX317EPA+ in existing designs?

A: Yes. MAX317EPA+ is a direct variant with identical electrical specifications and 8-DIP package configuration. The primary difference is ROHS3 compliance certification. No circuit modifications are required.

Q: What are the key differences between MAX317EPA and ADG417BNZ?

A: Both parts share identical on-state resistance (35Ohm), switch circuit configuration (SPST - NC), and package type (8-DIP). ADG417BNZ has faster turn-off time (100ns versus 145ns) and lower charge injection (7pC versus 3pC). However, ADG417BNZ supply voltage specifications are narrower: 12V single supply and ±15V dual supply, compared to MAX317EPA's 10V ~ 30V single supply and ±4.5V ~ 20V dual supply.

Q: Is DG417DJ-E3 suitable for high-frequency applications?

A: DG417DJ-E3 maintains the same switch timing as MAX317EPA (175ns, 145ns) and operates across the full -40°C ~ 85°C temperature range. However, charge injection is significantly higher (60pC versus 3pC), which may impact performance in precision analog switching applications requiring minimal charge injection.

Q: Are all substitute parts available in the same packaging?

A: Yes. MAX317EPA, MAX317EPA+, ADG417BNZ, and DG417DJ-E3 are all housed in 8-DIP (0.300", 7.62mm) through-hole packages with identical pinout compatibility.

Q: Which substitute part should be selected for new production designs?

A: ADG417BNZ or DG417DJ-E3 are recommended for new designs due to active product status and assured long-term availability. Selection between these two depends on charge injection requirements and supply voltage compatibility with your system design.

Q: Do all substitute parts meet the same compliance standards?

A: MAX317EPA is RoHS non-compliant. MAX317EPA+, ADG417BNZ, and DG417DJ-E3 are all ROHS3 compliant and REACH unaffected. For applications requiring RoHS compliance, use MAX317EPA+, ADG417BNZ, or DG417DJ-E3.
