DG412HSAK Equivalent & Substitute Parts

Part Overview

The DG412HSAK 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 part is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing production support.

Engineering Selection Recommendations

DG412AK/883B Selection Criteria:

Active product status with ongoing manufacturer support
Maintains full temperature range compatibility (-55°C to 125°C)
Improved on-state resistance (30Ohm) and charge injection (5pC) provide superior performance margins
16-CDIP package is mechanically and electrically compatible with 16-CERDIP footprint
Suitable for applications requiring extended temperature operation and non-compliant RoHS environments

MAX392CPE+Selection Criteria:

Active product status with RoHS3 compliance certification
Superior charge injection performance (2pC) and leakage current (100pA)
Restricted operating temperature range (0°C to 70°C) limits applicability to commercial-grade systems only
16-PDIP package compatible with through-hole mounting footprints
Recommended for new designs requiring regulatory compliance and commercial temperature operation
Not suitable for applications requiring -55°C to 125°C industrial temperature range

Frequently Asked Questions (FAQ)

Q: Can DG412AK/883B directly replace DG412HSAK in existing PCB layouts? A: Yes. Both parts use 16-pin DIP-class through-hole packages with 0.300" (7.62mm) spacing. Pin-to-pin compatibility is maintained. Verify supply voltage requirements in your application fall within the DG412AK/883B operating range (10V ~ 30V single supply, ±4.5V ~ 20V dual supply).

Q: Is MAX392CPE+ suitable for industrial temperature applications? A: No. The MAX392CPE+ operating temperature range is 0°C to 70°C, which does not cover the industrial range of -55°C to 125°C specified for the DG412HSAK. Use MAX392CPE+ only for commercial-grade applications operating within 0°C to 70°C.

Q: What are the key electrical differences between the three parts? A: DG412AK/883B offers improved on-state resistance (30Ohm vs. 35Ohm) and significantly lower charge injection (5pC vs. 22pC). MAX392CPE+ matches the 35Ohm on-state resistance but provides the lowest charge injection (2pC) and leakage current (100pA). Both substitutes reduce channel capacitance from 12pF to 9pF.

Q: Are there supply voltage compatibility concerns? A: Yes. The DG412HSAK supports higher single-supply voltages (13V ~ 44V) compared to DG412AK/883B (10V ~ 30V) and MAX392CPE+ (3V ~ 15V). Verify your application's supply voltage falls within the substitute part's specified range before selection.

Q: Which substitute is recommended for new product designs? A: For commercial-temperature applications (0°C to 70°C), MAX392CPE+ is preferred due to RoHS3 compliance and superior electrical performance. For industrial-temperature applications (-55°C to 125°C), DG412AK/883B is the appropriate choice, as it maintains the full temperature range and active product status.

Q: Do package differences affect PCB layout? A: 16-CERDIP, 16-CDIP, and 16-PDIP packages are mechanically compatible for through-hole mounting with 0.300" (7.62mm) spacing. No PCB layout modifications are required for package substitution.
