MAX352CPE Equivalent & Substitute Parts

Part Overview

The MAX352CPE is a 4-circuit SPST-NO IC switch manufactured by Analog Devices Inc./Maxim Integrated, designed for signal routing and switching applications requiring low on-state resistance and fast switching performance. The device operates with single supply (10V to 30V) or dual supply (±4.5V to ±20V) configurations and is packaged in a 16-DIP form factor.

The MAX352CPE is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance or redesign initiatives.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX352CPE is determined by strict equivalence across the following critical parameters:

Switch circuit topology (SPST - NO configuration)
Number of independent circuits (4 circuits)
Multiplexer/demultiplexer ratio (1:1)
On-state resistance specification (35Ω maximum)
Channel-to-channel resistance matching (2Ω maximum)
Supply voltage ranges (single and dual supply compatibility)
Switching performance (Ton/Toff specifications)
Electrical characteristics (charge injection, capacitance, leakage current, crosstalk)
Package form factor (16-DIP through-hole)
Operating temperature range (0°C ~ 70°C)

Only parts meeting all these criteria across their complete electrical and mechanical specifications qualify as direct substitutes.

Engineering Selection Recommendations

The MAX352CPE+ is a direct electrical and mechanical equivalent to the MAX352CPE. Both parts share identical electrical specifications across all switching, timing, and signal integrity parameters. The primary distinction is product status and regulatory compliance.

The MAX352CPE is obsolete and no longer in active production. The MAX352CPE+ is the active production equivalent from the same manufacturer, offering continued supply chain availability and support.

The MAX352CPE+ achieves ROHS3 compliance, whereas the original MAX352CPE is RoHS non-compliant. Both parts maintain identical MSL ratings and REACH status. For new designs or system redesigns, the MAX352CPE+ is the appropriate selection. For legacy system maintenance requiring exact part matching, the MAX352CPE remains functionally equivalent where available inventory permits.

Frequently Asked Questions (FAQ)

Q: Can MAX352CPE+ be used as a direct replacement for MAX352CPE in existing designs?

A: Yes. The MAX352CPE+ is electrically and mechanically identical to the MAX352CPE across all specified parameters. Both parts feature identical on-state resistance, switching times, supply voltage ranges, and package form factors. Direct substitution is supported without circuit modification.

Q: What is the primary difference between MAX352CPE and MAX352CPE+?

A: The MAX352CPE+ is the active production variant with ROHS3 compliance. The MAX352CPE is obsolete. All electrical and mechanical specifications are identical. The packaging differs only in that MAX352CPE+ is supplied in tube packaging, whereas MAX352CPE packaging is not specified in the provided data.

Q: Are there any compatibility concerns when substituting MAX352CPE with MAX352CPE+?

A: No compatibility concerns exist. Both parts are 16-DIP through-hole packages with identical pinout, electrical characteristics, and operating parameters. PCB layout and circuit design require no modification.

Q: Does the RoHS compliance difference affect functional performance?

A: No. RoHS compliance is a regulatory and material composition specification. It does not affect electrical performance, switching characteristics, or signal integrity. Both parts deliver identical functional performance in circuit applications.

Q: What supply voltage configurations are supported by these parts?

A: Both MAX352CPE and MAX352CPE+ support single supply operation (10V to 30V) and dual supply operation (±4.5V to ±20V). Circuit design must specify the appropriate supply configuration for the application.

Q: Are these parts suitable for high-frequency signal switching applications?

A: Both parts support switching times of 175ns (Ton) and 145ns (Toff) with crosstalk performance of -85dB @ 1MHz. Application suitability depends on specific frequency and signal integrity requirements beyond the scope of this substitution reference.
