DG211CJ Equivalent & Substitute Parts

Part Overview

The DG211CJ is a 4-circuit SPST-NC (Single Pole Single Throw - Normally Closed) analog switch IC manufactured by Renesas Electronics Corporation in a 16-DIP package. This component functions as a precision electronic switch with 175Ohm on-state resistance, designed for signal routing and multiplexing applications requiring low on-resistance and fast switching characteristics.

The DG211CJ is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across the core switching parameters: circuit topology (SPST-NC), number of circuits (4), package format (16-DIP), and electrical performance within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DG211CJ is determined by strict adherence to the following core parameters:

Mandatory Compatibility Criteria:

• Switch circuit topology: SPST - NC (Single Pole Single Throw - Normally Closed)
• Number of circuits: 4
• Package format: 16-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Multiplexer/Demultiplexer circuit: 1:1

Electrical Performance Parameters (Allowable Variation):

• On-state resistance: Must not exceed 175Ohm maximum
• Supply voltage range: Must support ±15V dual supply operation
• Switch timing: Ton and Toff specifications
• Leakage current: Must not exceed 5nA maximum
• Channel capacitance: 5pF (CS(off), CD(off))
• Crosstalk: -90dB @ 100kHz or better

Three substitute parts meet these criteria with varying electrical performance characteristics and product status classifications.

Engineering Selection Recommendations

DG211CJ+ (Analog Devices Inc./Maxim Integrated)

The DG211CJ+ maintains identical on-state resistance (175Ohm) and crosstalk performance (-90dB @ 100kHz) to the original DG211CJ, with matching operating temperature range (0°C ~ 70°C). This part is classified as active and ROHS3 compliant, providing regulatory compliance for new designs. The supply voltage range (±4.5V ~ 18V) encompasses the original ±15V specification. This substitute is the closest functional equivalent for direct replacement in existing designs.

ADG211AKNZ (Analog Devices Inc.)

The ADG211AKNZ offers improved on-state resistance (115Ohm, 34% lower than DG211CJ) and extended operating temperature range (-40°C ~ 85°C). This part is active and ROHS3 compliant. The supply voltage range (±15V) matches the original specification exactly. Crosstalk performance is -80dB @ 100kHz, which is 10dB lower than the original. This substitute is suitable for applications where lower on-resistance and extended temperature operation are beneficial.

DG211BDJ-E3 (Vishay Siliconix)

The DG211BDJ-E3 provides the lowest on-state resistance (85Ohm, 51% lower than DG211CJ) and superior crosstalk performance (-95dB @ 100kHz, 5dB better than original). Leakage current is significantly reduced to 500pA. This part is active and ROHS3 compliant with extended operating temperature range (-40°C ~ 85°C). The supply voltage range (±4.5V ~ 22V) exceeds the original specification. This substitute is optimal for applications requiring minimal on-resistance, superior signal isolation, and extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can DG211CJ+ be used as a direct replacement for DG211CJ?

A: Yes. The DG211CJ+ maintains identical on-state resistance (175Ohm), crosstalk (-90dB @ 100kHz), and operating temperature range (0°C ~ 70°C). The supply voltage range (±4.5V ~ 18V) encompasses the original ±15V specification. Pin configuration and package format (16-DIP) are identical.

Q: What is the primary difference between ADG211AKNZ and DG211BDJ-E3?

A: Both are active substitutes with extended temperature operation (-40°C ~ 85°C). The DG211BDJ-E3 offers lower on-state resistance (85Ohm vs. 115Ohm) and superior crosstalk performance (-95dB vs. -80dB @ 100kHz). The ADG211AKNZ supply voltage range is ±15V (matching original), while DG211BDJ-E3 supports ±4.5V ~ 22V.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (DG211CJ+, ADG211AKNZ, DG211BDJ-E3) are ROHS3 compliant. The original DG211CJ is RoHS non-compliant.

Q: Which substitute part has the fastest switching time?

A: The DG211BDJ-E3 has the fastest switching characteristics with Ton = 300ns and Toff = 200ns. The original DG211CJ specifies Ton = 460ns and Toff = 450ns.

Q: Can these parts be used interchangeably in the same PCB layout?

A: Yes. All parts use identical 16-DIP (0.300", 7.62mm) through-hole package format with the same pin configuration (1:1 multiplexer/demultiplexer, 4 circuits, SPST-NC topology). No PCB layout modifications are required.

Q: What is the leakage current specification for each substitute?

A: DG211CJ+ and ADG211AKNZ specify 5nA maximum leakage current, matching the original DG211CJ. The DG211BDJ-E3 specifies 500pA maximum, which is significantly lower.

Q: Which substitute part supports the widest supply voltage range?

A: The DG211BDJ-E3 supports ±4.5V ~ 22V dual supply operation, providing the widest voltage range among all substitutes and exceeding the original ±15V specification.
