DG441CJ+ Equivalent & Substitute Parts Reference

Part Overview

The DG441CJ+ is a 4-circuit SPST-NC (Single Pole Single Throw - Normally Closed) analog switch manufactured by Analog Devices Inc./Maxim Integrated. This interface component operates as a 1:1 multiplexer/demultiplexer with 85Ohm on-state resistance and is housed in a 16-pin DIP package for through-hole mounting. The device is actively produced and maintains full RoHS3 compliance with REACH unaffected status. Identifying equivalent and substitute parts is necessary when addressing supply chain constraints, lead time requirements, or specific application compatibility needs while maintaining electrical and mechanical performance standards.

Substitute Part Grouping Explanation

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

Circuit Architecture Requirements:

• Switch circuit type must be SPST - NC
• Number of circuits must be 4
• Multiplexer/demultiplexer configuration must be 1:1

Electrical Performance Requirements:

• On-state resistance maximum of 85Ohm
• Channel-to-channel matching (ΔRon) not exceeding 4Ohm
• Supply voltage ranges: Single supply 10V ~ 30V or dual supply ±4.5V ~ 20V
• Switch timing: Ton ≤ 250ns, Toff ≤ 120ns
• Charge injection ≤ 5pC
• Channel capacitance (CS(off), CD(off)) ≤ 4pF each
• Leakage current (IS(off)) ≤ 500pA
• Crosstalk ≤ -100dB @ 1MHz

Physical and Compliance Requirements:

• Package type: 16-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Operating temperature range: 0°C ~ 70°C minimum
• RoHS3 compliance mandatory
• MSL rating of 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

The DG441CJ+ is an active product with full RoHS3 compliance and REACH unaffected status, making it suitable for current design implementations. When direct equivalents are unavailable, component selection must maintain all specified electrical parameters within their defined ranges. The 16-DIP through-hole package format is a critical constraint for applications requiring this specific form factor. Active product status ensures ongoing availability and manufacturing support. RoHS3 compliance is mandatory for applications subject to environmental regulations. MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the DG441CJ+?

A: A valid substitute must maintain identical circuit architecture (4-circuit SPST-NC, 1:1 configuration), match or exceed electrical performance specifications (85Ohm on-state resistance, 4Ohm maximum channel matching, specified voltage ranges, timing parameters, and leakage characteristics), use the same 16-DIP through-hole package, and maintain RoHS3 compliance with MSL rating of 1.

Q: Can the DG441CJ+ be replaced with a different package type?

A: No. The 16-DIP (0.300", 7.62mm) through-hole package is a physical requirement for board compatibility. Alternative package types (such as surface-mount variants) are not substitutes for this application.

Q: Are there performance trade-offs when selecting substitute parts?

A: Substitute parts must meet or exceed all specified parameters. Any parameter below the specified maximum (such as lower on-state resistance or reduced leakage current) is acceptable. Parameters must not exceed specified maximums.

Q: What compliance certifications are required for substitutes?

A: Substitute parts must maintain RoHS3 compliance and REACH unaffected status. MSL rating of 1 (Unlimited) is required to ensure compatibility with standard handling and storage procedures.

Q: How does the 16-DIP package affect substitution options?

A: The 16-DIP through-hole package is a fixed requirement for board-level compatibility. This package type limits substitution options to components available in identical physical form factors. Surface-mount alternatives or different pin counts are not compatible.

Q: What is the significance of the 1:1 multiplexer/demultiplexer configuration?

A: The 1:1 configuration indicates a single input-to-single output switching architecture per circuit. Substitutes must maintain this exact configuration; different multiplexing ratios (such as 2:1 or 4:1) are not compatible.
