DG412HSAK-E3 Equivalent & Substitute Parts

Part Overview

The DG412HSAK-E3 is a 4-circuit SPST-NO analog switch IC manufactured by Vishay Siliconix, housed in a 16-CERDIP package. This component functions as a single-pole single-throw normally-open switch array with 35Ohm on-state resistance, designed for signal routing and multiplexing applications across industrial and commercial temperature ranges (-55°C to 125°C).

The DG412HSAK-E3 is classified as obsolete. Equivalent substitute parts are available from active product lines, making substitution necessary for new designs and ongoing procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DG412HSAK-E3 is determined by the following mandatory parameters:

• Switch Circuit Configuration: Must be SPST - NO (4 circuits, 1:1 multiplexer)
• On-State Resistance: Maximum 35Ohm (allows lower resistance values)
• Supply Voltage Compatibility: Must support the required voltage range for the application
• Operating Temperature Range: Must cover -55°C to 125°C minimum
• Package/Mounting: Through-hole DIP-format packages (16-CERDIP or 16-PDIP acceptable)
• Base Product Family: DG412 series

Two substitute parts meet these criteria: DG412AK/883B and DG412DJZ. Both maintain the core 4-circuit SPST-NO architecture and are pin-compatible alternatives available from active product lines.

Parameter Comparison

Engineering Selection Recommendations

DG412AK/883B Selection Criteria:

• Active product status with established supply chain
• Lower on-state resistance (30Ohm vs. 35Ohm) provides improved performance margin
• Reduced charge injection (5pC vs. 22pC) and lower channel capacitance benefit high-frequency applications
• RoHS non-compliant status requires verification against design compliance requirements
• Voltage supply range (10V ~ 30V single, ±4.5V ~ 20V dual) is narrower than the main part; verify application voltage requirements fall within this range
• Maintains full industrial temperature range (-55°C ~ 125°C)

DG412DJZ Selection Criteria:

• Active product status with established supply chain
• Identical on-state resistance (35Ohm) to main part ensures direct electrical equivalence
• ROHS3 compliant, matching main part compliance profile
• Wider single supply voltage range (5V ~ 44V) provides superior flexibility
• Operating temperature range limited to -40°C ~ 85°C; suitable only for applications not requiring full -55°C operation
• Lower leakage current (100pA vs. 250pA) offers improved performance in low-power applications
• 16-PDIP package is mechanically compatible with through-hole PCB layouts

Compliance Considerations:

• DG412HSAK-E3 and DG412DJZ are ROHS3 compliant; DG412AK/883B is not
• All three parts are REACH unaffected and carry EAR99 ECCN classification
• Moisture sensitivity level is uniform across all parts (MSL 1 - Unlimited)

Frequently Asked Questions (FAQ)

Q: Can DG412AK/883B be used as a direct replacement for DG412HSAK-E3?

A: DG412AK/883B is electrically compatible for applications operating within its voltage range (10V ~ 30V single supply, ±4.5V ~ 20V dual supply) and full industrial temperature range (-55°C ~ 125°C). The lower on-state resistance (30Ohm) is advantageous. However, RoHS compliance status differs; verify your design requirements. If your application requires supply voltages below 10V or above 30V (single), this substitute is not suitable.

Q: What are the key differences between DG412DJZ and DG412HSAK-E3?

A: DG412DJZ maintains identical on-state resistance (35Ohm) and ROHS3 compliance. Primary differences are: (1) operating temperature range is -40°C to 85°C instead of -55°C to 125°C, limiting use in extreme cold environments; (2) wider single supply voltage range (5V ~ 44V) provides greater flexibility; (3) lower leakage current (100pA vs. 250pA). Package format differs (16-PDIP vs. 16-CERDIP) but both are through-hole compatible.

Q: Are the package formats interchangeable?

A: DG412HSAK-E3 uses 16-CERDIP, DG412AK/883B uses 16-CDIP, and DG412DJZ uses 16-PDIP. All three are 16-pin through-hole DIP packages with 0.300" (7.62mm) pitch and are mechanically compatible with standard DIP sockets and through-hole PCB layouts. Pin assignments are identical across the DG412 family.

Q: Which substitute should I select for a new design?

A: Selection depends on application requirements. For full industrial temperature range (-55°C ~ 125°C) with RoHS3 compliance, use DG412DJZ. For applications requiring lower on-state resistance and reduced charge injection within the narrower voltage range, use DG412AK/883B (verify RoHS compliance requirements). Both are active products with established supply availability.

Q: What is the impact of different on-state resistance values?

A: DG412AK/883B (30Ohm) provides lower insertion loss and reduced power dissipation compared to DG412HSAK-E3 and DG412DJZ (both 35Ohm). In signal routing applications, lower resistance minimizes signal attenuation. In switching applications, lower resistance reduces heat generation. The 5Ohm difference is typically negligible for most applications but may be significant in precision analog signal paths or high-current switching scenarios.

Q: Can I use DG412DJZ in applications requiring -55°C operation?

A: No. DG412DJZ operating temperature range is -40°C to 85°C. It is not rated for operation below -40°C. For applications requiring -55°C minimum temperature, use DG412HSAK-E3 (if available) or DG412AK/883B.
