DG441CJ Equivalent & Substitute Parts

Part Overview

The DG441CJ is a 4-circuit IC switch with SPST-NC (Single Pole Single Throw - Normally Closed) configuration manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with 85Ohm on-state resistance and is housed in a 16-DIP through-hole package. The DG441CJ is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the DG441CJ is determined by strict equivalence across the following critical parameters:

  • Switch circuit topology (SPST - NC configuration)
  • Number of independent circuits (4 circuits)
  • Multiplexer ratio (1:1)
  • On-state resistance specification (85Ohm maximum)
  • Channel-to-channel resistance matching (4Ohm maximum)
  • Supply voltage ranges (single and dual supply compatibility)
  • Switching speed characteristics (Ton, Toff)
  • Charge injection and capacitance specifications
  • Leakage current and crosstalk performance
  • Package form factor (16-DIP through-hole)
  • Operating temperature range (0°C ~ 70°C)

The DG441CJ+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Engineering Selection Recommendations

The DG441CJ+ is the direct equivalent substitute for the obsolete DG441CJ. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility in existing circuit designs.

The primary distinction between the two parts is product status and regulatory compliance. The DG441CJ is classified as obsolete and carries RoHS non-compliant status. The DG441CJ+ is an active product with ROHS3 compliance, making it suitable for new designs and applications subject to RoHS directives. Both parts maintain REACH Unaffected status and EAR99 export classification.

For applications requiring the DG441CJ, the DG441CJ+ provides equivalent performance with the advantage of current manufacturing availability and regulatory compliance. No circuit modifications or design changes are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the DG441CJ+ be used as a direct replacement for the DG441CJ?

A: Yes. The DG441CJ+ is electrically and mechanically identical to the DG441CJ across all specified parameters, including switch configuration, resistance characteristics, voltage ranges, switching speed, and package form factor. Direct substitution is possible without circuit modification.

Q: What is the significance of the RoHS compliance difference?

A: The DG441CJ is RoHS non-compliant, while the DG441CJ+ is ROHS3 compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the DG441CJ+ is the appropriate selection. Both parts are REACH Unaffected.

Q: Are there any differences in electrical performance between these parts?

A: No. Both the DG441CJ and DG441CJ+ meet identical electrical specifications for on-state resistance, switching time, charge injection, leakage current, crosstalk, and all other performance parameters listed in the parameter comparison table.

Q: Is the 16-DIP package compatible with existing PCB layouts?

A: Yes. Both parts use the same 16-DIP (0.300", 7.62mm) through-hole package. PCB layouts designed for the DG441CJ will accommodate the DG441CJ+ without modification.

Q: What is the availability status of these parts?

A: The DG441CJ is obsolete with limited inventory. The DG441CJ+ is an active product with current manufacturing support and availability.
