MAX4602CWE Equivalent & Substitute Parts

Part Overview

The MAX4602CWE is a 4-circuit IC switch manufactured by Analog Devices Inc./Maxim Integrated, configured as a SPST-NO (Single Pole Single Throw - Normally Open) multiplexer with 1:1 circuit topology. This component operates across a wide supply voltage range (4.5V to 36V single supply, or ±4.5V to ±20V dual supply) and features a maximum on-state resistance of 2.5Ohm with 250ns/350ns switching times.

The MAX4602CWE is classified as obsolete. Locating direct equivalents becomes necessary for ongoing production support, maintenance applications, and system redesigns where component availability is critical.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4602CWE is determined by strict equivalence across the following electrical and mechanical parameters:

Switch circuit topology (SPST - NO configuration)
Multiplexer circuit ratio (1:1)
Number of independent circuits (4)
On-state resistance specification (2.5Ohm maximum)
Channel-to-channel resistance matching tolerance (100mOhm)
Supply voltage operating ranges (single and dual supply)
Switching time performance (Ton/Toff specifications)
Charge injection and capacitance characteristics
Leakage current and crosstalk performance
Package form factor (16-SOIC surface mount)
Operating temperature range (0°C to 70°C)

The MAX4602CWE+ qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction lies in product status and compliance certifications.

Engineering Selection Recommendations

The MAX4602CWE+ is the direct functional equivalent of the MAX4602CWE. Both components share identical electrical performance specifications and mechanical packaging. Selection between these parts should be based on the following criteria:

MAX4602CWE+ is the preferred choice for new designs and ongoing production applications. This variant carries Active product status, ensuring long-term availability and supply chain stability. The MAX4602CWE+ meets ROHS3 compliance requirements, satisfying environmental and regulatory standards for modern manufacturing and end-market applications. Tube packaging provides standard handling and storage compatibility with automated assembly processes.

MAX4602CWE remains suitable for legacy system maintenance and repair applications where existing inventory exists. However, the Obsolete product status indicates limited future availability. RoHS non-compliance may present restrictions in certain regulated markets or customer specifications.

Frequently Asked Questions (FAQ)

Q: Are MAX4602CWE and MAX4602CWE+ electrically interchangeable?

A: Yes. Both components feature identical electrical specifications including on-state resistance, switching times, supply voltage ranges, and signal integrity parameters. Direct pin-for-pin substitution is supported without circuit modification.

Q: What is the significance of the product status difference?

A: MAX4602CWE is classified as Obsolete, indicating discontinued production and limited component availability. MAX4602CWE+ maintains Active status with ongoing manufacturing support. For applications requiring long-term component sourcing, MAX4602CWE+ is the appropriate selection.

Q: Does RoHS compliance affect functional performance?

A: RoHS compliance does not alter electrical or mechanical performance. ROHS3 compliance of MAX4602CWE+ reflects manufacturing process standards and material composition restrictions. Selection based on RoHS status depends on end-market requirements and customer specifications rather than component functionality.

Q: Are the 16-SOIC packages identical between both variants?

A: Yes. Both MAX4602CWE and MAX4602CWE+ use the same 16-SOIC package form factor (0.295", 7.50mm width). PCB footprints, land patterns, and assembly processes are identical. Packaging format (Tube for MAX4602CWE+) affects handling and storage but not physical component dimensions.

Q: Can MAX4602CWE+ be used as a drop-in replacement in existing assemblies?

A: Yes. Identical electrical specifications, pin configuration, and package dimensions enable direct substitution in existing circuit designs without redesign or re-qualification.
