MAX358EPE Equivalent & Substitute Parts Reference

Part Overview

The MAX358EPE is an 8:1 analog multiplexer IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-DIP package. This component functions as a single-circuit switch with 1.8kOhm on-state resistance, designed for analog signal routing applications requiring low impedance paths and fast switching performance. The MAX358EPE is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX358EPE is determined by the following critical parameters:

Primary Compatibility Criteria:

Multiplexer configuration: 8:1 topology
Circuit count: Single circuit
Package type: 16-DIP form factor

Engineering Selection Recommendations

MAX358EPE+ (Analog Devices/Maxim): This part represents the direct successor within the Analog Devices product line. It maintains identical electrical specifications for on-state resistance, supply voltage range, and switching characteristics. The MAX358EPE+ offers superior leakage current performance (1nA vs. 10µA) and holds active product status with ROHS3 compliance certification. This part is the preferred substitute for applications requiring minimal design modification and continued support from the original manufacturer.

MPC508AP (Texas Instruments): This cross-manufacturer alternative provides 8:1 multiplexer functionality in the same 16-DIP package with compatible operating temperature range. The MPC508AP features lower on-state resistance (1.5kOhm vs. 1.8kOhm) and faster switching times (200ns/250ns vs. 300ns), which may improve signal integrity in bandwidth-sensitive applications. The extended supply voltage range (±5V ~ 22V) provides additional operational flexibility. This part is suitable for designs where cross-manufacturer sourcing is acceptable and improved electrical performance is beneficial. MPC508AP carries active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can MAX358EPE+ be used as a direct replacement for MAX358EPE?

A: Yes. The MAX358EPE+ maintains identical on-state resistance (1.8kOhm), supply voltage range (±4.5V ~ 18V), switching times (300ns typical), and channel capacitance specifications. Both parts use the 16-DIP package. The primary differences are product status (active vs. obsolete) and improved leakage current performance in the MAX358EPE+. No circuit modifications are required.

Q: What are the key differences between MAX358EPE+ and MPC508AP?

A: Both parts provide 8:1 multiplexing in 16-DIP packages with identical operating temperature ranges. The MPC508AP offers lower on-state resistance (1.5kOhm vs. 1.8kOhm), faster switching performance (200ns/250ns vs. 300ns), and extended supply voltage range (±5V ~ 22V vs. ±4.5V ~ 18V). The MAX358EPE+ maintains exact electrical compatibility with the original MAX358EPE. Selection depends on whether improved performance characteristics or exact parameter matching is prioritized.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both MAX358EPE+ and MPC508AP are ROHS3 compliant. The original MAX358EPE is RoHS non-compliant. If RoHS compliance is a design requirement, either substitute part satisfies this criterion.

Q: Does package compatibility extend to PCB layout?

A: Both substitute parts use the 16-DIP (0.300", 7.62mm) package, matching the original MAX358EPE footprint. PCB layout modifications are not required for package accommodation. Pin configuration should be verified against specific application schematics to ensure functional compatibility.

Q: Which substitute part should be selected for new designs?

A: For new designs, MAX358EPE+ is recommended as the primary choice due to manufacturer continuity, active product status, and superior leakage current characteristics. MPC508AP is suitable when improved electrical performance or cross-manufacturer sourcing strategy is preferred. Both parts meet the functional requirements of 8:1 analog multiplexing in the 16-DIP package format.
