Engineering Selection Recommendations

For Direct PCB Substitution (Same Package):

MAX393ESE+ is the primary equivalent for the DG413HSAK. Both devices use 16-SOIC surface-mount packaging, enabling direct PCB layout compatibility. MAX393ESE+ is actively manufactured and ROHS3 compliant, addressing the obsolescence and compliance limitations of the DG413HSAK. The 35Ohm on-state resistance matches the original specification. Operating temperature range is reduced (-40°C to 85°C versus -55°C to 125°C), which must be evaluated against application requirements.

For Through-Hole Applications:

DG413AK and DG413AK/883B provide functional equivalence with 16-CDIP through-hole packaging. Both offer improved on-state resistance (30Ohm) and lower charge injection (5pC). DG413AK is ROHS3 compliant and actively produced. DG413AK/883B maintains RoHS non-compliant status. Both support the full -55°C to 125°C operating temperature range. These options require PCB redesign due to package form factor change.

Compliance Considerations:

For new designs requiring RoHS3 compliance, MAX393ESE+ or DG413AK are appropriate selections. For legacy systems where RoHS compliance is not mandated, all three substitutes remain functionally viable.

Frequently Asked Questions (FAQ)

Q: Can MAX393ESE+ directly replace DG413HSAK on existing PCBs?

A: Yes. Both devices use 16-SOIC surface-mount packaging with identical pin spacing and footprint dimensions (0.154" width, 3.90mm). No PCB layout modifications are required. Electrical parameters are compatible within the specified operating ranges.

Q: What is the key difference between DG413AK and DG413AK/883B?

A: Both parts are functionally identical with 30Ohm on-state resistance and 16-CDIP through-hole packaging. The primary difference is RoHS compliance status: DG413AK is ROHS3 compliant, while DG413AK/883B is RoHS non-compliant. Select based on regulatory requirements for your application.

Q: Why does MAX393ESE+ have a narrower operating temperature range?

A: MAX393ESE+ operates from -40°C to 85°C, compared to the DG413HSAK range of -55°C to 125°C. Applications requiring full -55°C to 125°C operation must use DG413AK or DG413AK/883B. Verify your system's thermal requirements before selection.

Q: Are there supply voltage compatibility issues between substitutes?

A: Yes. MAX393ESE+ operates on 3V–15V single supply or ±3V–±8V dual supply, which is narrower than DG413HSAK (13V–44V single, ±5V–±20V dual). DG413AK and DG413AK/883B support 10V–30V single supply or ±4.5V–±20V dual supply. Confirm your circuit's supply voltage falls within the selected substitute's range.

Q: What is the impact of lower charge injection in MAX393ESE+?

A: MAX393ESE+ has 2pC charge injection versus 22pC in DG413HSAK. Lower charge injection reduces signal distortion in precision analog switching applications. This is a performance improvement for most applications but must be evaluated in high-frequency or low-level signal circuits.

Q: Can DG413AK be used in surface-mount designs?

A: No. DG413AK uses 16-CDIP through-hole packaging and cannot be mounted on surface-mount PCBs. For surface-mount applications, use MAX393ESE+ or redesign the PCB for through-hole components.

Q: Which substitute offers the best overall performance?

A: MAX393ESE+ provides the lowest charge injection (2pC), lowest leakage current (100pA), and fastest Toff (75ns). However, it has a narrower operating temperature range. DG413AK offers the best balance of performance, compliance, and temperature range for most applications.
