Engineering Selection Recommendations

Direct Equivalent (Parametric Match): DG441CJ+ is a parametric equivalent with identical electrical specifications to the DG444CJ+, differing only in base product designation. Both maintain the same on-state resistance, supply voltage ranges, and operating temperature window. Selection between these two is based on manufacturer sourcing preference and inventory availability.

Extended Temperature Range Substitutes: ADG444BNZ, DG441DJ-E3, DG444BDJ-E3, and DG444DJ-E3 all support extended operating temperature ranges (-40°C ~ 85°C) compared to the DG444CJ+ (0°C ~ 70°C). These parts are suitable for applications requiring operation beyond the standard commercial temperature range. All maintain ROHS3 compliance and MSL 1 certification.

Performance-Enhanced Substitute: ADG444BNZ offers improved switching performance with reduced on-state resistance (70Ohm vs. 85Ohm), faster switch times (Ton 110ns, Toff 60ns), and lower charge injection (1pC). This part is manufactured by Analog Devices Inc. and is recommended for applications where lower insertion loss and faster switching are critical. Supply voltage is fixed at 12V single supply or ±15V dual supply.

Broad Supply Voltage Range Substitute: DG444DJ-E3 supports the widest supply voltage range (5V ~ 36V single supply; ±5V ~ 20V dual supply) among all substitutes, making it suitable for applications with variable or wide-range power supplies. This Vishay Siliconix part maintains 85Ohm on-state resistance and -100dB crosstalk performance.

All substitute parts maintain:

SPST-NC switch circuit topology
4-circuit configuration with 1:1 multiplexer/demultiplexer operation
16-DIP through-hole package format
500pA maximum leakage current
ROHS3 compliance and MSL 1 rating
Active product status

Frequently Asked Questions (FAQ)

Q: Can DG441CJ+ be used as a direct replacement for DG444CJ+? A: Yes. DG441CJ+ is a parametric equivalent with identical electrical specifications, on-state resistance (85Ohm), supply voltage ranges (10V ~ 30V single; ±4.5V ~ 20V dual), and operating temperature (0°C ~ 70°C). The difference is in the base product designation only.

Q: What is the primary advantage of ADG444BNZ over DG444CJ+? A: ADG444BNZ provides improved switching performance with lower on-state resistance (70Ohm vs. 85Ohm), faster switching times (Ton 110ns vs. 250ns; Toff 60ns vs. 140ns), and reduced charge injection (1pC vs. 5pC). However, it operates at fixed supply voltages (12V single or ±15V dual) rather than the variable ranges of DG444CJ+.

Q: Are all substitute parts compatible with the same PCB footprint? A: Yes. All substitute parts use the 16-DIP (0.300", 7.62mm) package with through-hole mounting. PCB layout and footprint remain identical across all listed substitutes.

Q: Which substitute part supports the widest supply voltage range? A: DG444DJ-E3 supports the broadest supply voltage specifications: 5V ~ 36V for single supply and ±5V ~ 20V for dual supply. This makes it suitable for applications with variable power supply requirements.

Q: Do all substitute parts meet the same environmental and compliance standards? A: Yes. All substitute parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain ECCN EAR99 and HTSUS 8542.39.0001 classifications. All parts are currently in active production status.

Q: What is the difference between DG444CJ+ and DG444BDJ-E3 in terms of on-state resistance? A: DG444CJ+ has a maximum on-state resistance of 85Ohm, while DG444BDJ-E3 is rated at 80Ohm. DG444BDJ-E3 also supports an extended operating temperature range (-40°C ~ 85°C) and wider supply voltage ranges (13V ~ 36V single; ±7V ~ 22V dual).

Q: Which substitute offers the fastest switching performance? A: ADG444BNZ provides the fastest switching times with Ton of 110ns and Toff of 60ns, compared to DG444CJ+ specifications of 250ns and 140ns respectively.

Q: Can DG444CJ+ be used in applications requiring -40°C operation? A: No. DG444CJ+ operates from 0°C ~ 70°C. For extended low-temperature operation down to -40°C, use ADG444BNZ, DG441DJ-E3, DG444BDJ-E3, or DG444DJ-E3.
