Substitute Part Grouping Explanation

Substitution eligibility for the ADG201HSKP is determined by strict equivalence across the following critical parameters:

Switch circuit configuration (SPST - NC)
Number of circuits (4)
Multiplexer/demultiplexer circuit topology (1:1)
On-state resistance specification (50Ohm maximum)
Channel-to-channel matching tolerance (1.5Ohm)
Supply voltage ranges (single and dual configurations)
Switch timing specifications (50ns maximum for Ton and Toff)
Charge injection (10pC)
Channel capacitance values (10pF for both CS(off) and CD(off))
Leakage current specification (1nA maximum)
Crosstalk performance (-86dB @ 100kHz)
Operating temperature range (-40°C ~ 85°C)
Physical package format (20-PLCC, 9x9 footprint)

The ADG201HSKPZ meets all these criteria and qualifies as a direct substitute for the obsolete ADG201HSKP.

Engineering Selection Recommendations

The ADG201HSKPZ is the direct substitute for the obsolete ADG201HSKP. Both components are manufactured by Analog Devices Inc. and maintain identical electrical and mechanical specifications across all critical parameters. The ADG201HSKPZ offers the advantage of active product status, ensuring continued availability and manufacturing support.

The ADG201HSKPZ carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to environmental and hazardous substance restrictions. The obsolete ADG201HSKP lacks specified compliance documentation, making the ADG201HSKPZ the preferred choice for new designs and system upgrades.

Both parts share identical package geometry (20-PLCC, 9x9 footprint) and surface mount configuration, enabling direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the ADG201HSKPZ directly replace the ADG201HSKP without circuit modifications?

A: Yes. The ADG201HSKPZ maintains identical electrical specifications and physical package dimensions. Direct substitution is possible without circuit redesign or PCB layout changes.

Q: What is the primary reason for substituting the ADG201HSKP?

A: The ADG201HSKP is classified as obsolete. The ADG201HSKPZ is the active equivalent, ensuring long-term component availability and manufacturing support.

Q: Are there differences in supply voltage requirements between these parts?

A: No. Both the ADG201HSKP and ADG201HSKPZ support identical single supply (10.8V ~ 16.5V) and dual supply (±14.6V ~ 16.5V) configurations.

Q: Do these components require different PCB footprints?

A: No. Both parts use the 20-PLCC (9x9) surface mount package with identical J-Lead configuration. Existing PCB designs require no modification.

Q: What compliance certifications does the ADG201HSKPZ carry?

A: The ADG201HSKPZ is ROHS3 compliant and REACH unaffected. The obsolete ADG201HSKP does not specify compliance status.

Q: Are the switching time specifications identical?

A: Yes. Both components specify maximum switch times of 50ns for both Ton and Toff, maintaining identical performance in timing-critical applications.

Q: Is inventory availability a consideration for component selection?

A: The ADG201HSKPZ is actively manufactured and supported. The ADG201HSKP is obsolete with limited remaining inventory. For new designs and long-term system support, the ADG201HSKPZ is the appropriate selection.
