DG201ACJ Equivalent & Substitute Parts

Part Overview

The DG201ACJ is a 4-circuit SPST-NC (Single Pole Single Throw - Normally Closed) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated in a 16-DIP package. This component operates with dual supply voltage (±4.5V ~ 18V) and features 200Ohm on-state resistance with 600ns/450ns switch timing. The DG201ACJ is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts maintain the same functional topology (4-circuit 1:1 multiplexer configuration, SPST-NC switching) while offering improved performance characteristics, active product status, and enhanced compliance certifications.

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance): DG201ACJ+ is the direct active equivalent with identical electrical specifications and pinout. This part maintains 200Ohm on-state resistance and ±4.5V ~ 18V dual supply range. Selection of DG201ACJ+ is recommended for applications requiring no design modification. The primary advantage is active product status and ROHS3 compliance certification.

Performance-Enhanced Substitutes (Lower On-State Resistance): Parts with reduced on-state resistance (50Ohm to 90Ohm) offer improved signal integrity and reduced power dissipation. These include ADG201HSKNZ (50Ohm, 50ns switching), ADG201HSJNZ (50Ohm, 75ns switching), DG201HSDJ-E3 (50Ohm, 60ns switching), DG271BCJ-E3 (50Ohm, 65ns switching), ADG201AKNZ (90Ohm, 300ns switching), and ADG441BNZ (70Ohm, 110ns switching). All feature active product status and ROHS3 compliance. Supply voltage ranges vary; verify compatibility with application requirements.

Mid-Range Substitutes (85Ohm to 125Ohm On-State Resistance): DG201BDJ-E3 (85Ohm) and LTC201ACN#PBF (125Ohm) provide intermediate performance between the original DG201ACJ and lower-resistance alternatives. DG201BDJ-E3 supports extended supply range (±4.5V ~ 22V) and offers superior leakage current performance (500pA). LTC201ACN#PBF maintains 0°C ~ 70°C operating temperature matching the original part while providing active status and compliance.

Extended Temperature Range Substitutes: ADG201AKNZ, ADG201HSJNZ, ADG201HSKNZ, ADG441BNZ, DG201BDJ-E3, DG201HSDJ-E3, and DG271BCJ-E3 all support -40°C ~ 85°C operating temperature, extending beyond the DG201ACJ specification. These parts are suitable for industrial and automotive applications requiring wider temperature performance.

Compliance Consideration: All substitute parts listed carry ROHS3 compliance certification, addressing the non-compliant status of the obsolete DG201ACJ. This is a critical factor for new designs and procurement in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can DG201ACJ+ be used as a direct drop-in replacement for DG201ACJ? A: Yes. DG201ACJ+ maintains identical electrical specifications, pinout, and package configuration. The primary differences are active product status and ROHS3 compliance. No circuit modifications are required.

Q: What is the key difference between DG201ACJ and the ADG201 series substitutes? A: The ADG201 series (ADG201AKNZ, ADG201HSJNZ, ADG201HSKNZ) offers lower on-state resistance (50Ohm to 90Ohm versus 200Ohm), faster switching times, and extended operating temperature range (-40°C ~ 85°C). These improvements require verification of supply voltage compatibility, as the ADG201 series operates at ±10V ~ 15V or ±14.6V ~ 16.5V ranges.

Q: Are all substitute parts available in the same 16-DIP package? A: Yes. All substitute parts listed are packaged in 16-DIP (0.300", 7.62mm) through-hole configuration, maintaining mechanical compatibility with the original DG201ACJ footprint.

Q: Which substitute offers the best leakage current performance? A: ADG201HSJNZ, ADG201HSKNZ, and DG201HSDJ-E3 all feature 1nA maximum leakage current, compared to 5nA for the DG201ACJ. ADG441BNZ offers superior performance at 500pA maximum leakage current.

Q: What is the difference between DG201HSDJ-E3 and DG271BCJ-E3? A: Both parts feature 50Ohm on-state resistance and similar switching performance. DG201HSDJ-E3 supports wider supply voltage range (±7V ~ 22V) and offers lower charge injection (-5pC). DG271BCJ-E3 operates at fixed ±15V supply and features higher channel capacitance (8pF versus 5pF).

Q: Can I use HI3-0201-5Z as a substitute? A: HI3-0201-5Z is functionally compatible with 80Ohm on-state resistance and ±15V dual supply operation. However, it operates at 0°C ~ 75°C temperature range and features higher leakage current (500nA) compared to the DG201ACJ. Verify application requirements before selection.

Q: Which substitute is recommended for high-speed switching applications? A: ADG201HSKNZ offers the fastest switching performance at 50ns Ton/Toff with 50Ohm on-state resistance. ADG201HSJNZ provides 75ns switching with identical resistance. Both require ±14.6V ~ 16.5V supply voltage.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts listed carry ROHS3 compliance certification. The original DG201ACJ is RoHS non-compliant, making compliance-certified substitutes necessary for new designs in regulated markets.
