MAX301ESE Equivalent & Substitute Parts

Part Overview

The MAX301ESE is a 2-circuit IC switch with SPST-NO (Single Pole Single Throw - Normally Open) configuration, manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with 35Ohm on-state resistance and is housed in a 16-SOIC surface mount package. The MAX301ESE is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX301ESE is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the MAX301ESE+, which maintains identical functional specifications including switch circuit topology, on-state resistance, supply voltage ranges, switching characteristics, and package configuration. The substitution is valid because both parts share the same base product number (MAX301), identical electrical performance metrics, and compatible 16-SOIC surface mount packaging.

The key parameters governing substitution are:

• Switch circuit type and configuration (SPST - NO, 1:1 multiplexer)
• On-state resistance and channel matching specifications
• Supply voltage operating ranges (single and dual supply)
• Switching time and charge injection characteristics
• Package type and physical dimensions (16-SOIC)
• Operating temperature range

Engineering Selection Recommendations

The MAX301ESE+ is the direct active equivalent for the obsolete MAX301ESE. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance: the MAX301ESE+ is actively manufactured and ROHS3 compliant, whereas the MAX301ESE is obsolete and RoHS non-compliant.

For new designs and production applications, the MAX301ESE+ is the appropriate selection. The active product status ensures continued availability and manufacturing support. The ROHS3 compliance of the MAX301ESE+ aligns with current environmental and regulatory requirements for electronic components in most markets.

For legacy systems currently using the MAX301ESE, the MAX301ESE+ provides a direct replacement without circuit redesign or board layout modifications, as both parts share identical electrical performance and 16-SOIC package specifications.

Frequently Asked Questions (FAQ)

Q: Can the MAX301ESE+ directly replace the MAX301ESE in existing designs?

A: Yes. The MAX301ESE+ is electrically and mechanically equivalent to the MAX301ESE. Both parts feature identical on-state resistance (35Ohm), switching characteristics (150ns/100ns), supply voltage ranges, and 16-SOIC package configuration. No circuit modifications are required.

Q: What is the primary reason to transition from MAX301ESE to MAX301ESE+?

A: The MAX301ESE is classified as obsolete, limiting future availability and manufacturing support. The MAX301ESE+ is an active product with ongoing production. Additionally, the MAX301ESE+ is ROHS3 compliant, meeting current regulatory standards, whereas the MAX301ESE is RoHS non-compliant.

Q: Are there any differences in packaging between these parts?

A: Both the MAX301ESE and MAX301ESE+ use the 16-SOIC surface mount package with identical physical dimensions (0.154" width, 3.90mm). The MAX301ESE+ is supplied in Tube packaging, while the MAX301ESE packaging specification was not provided. This does not affect electrical compatibility or board-level integration.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the MAX301ESE and MAX301ESE+ operate across the identical temperature range of -40°C to 85°C (TA).

Q: Are there any supply voltage differences between these parts?

A: No. Both parts support identical supply voltage configurations: single supply 10V ~ 30V (V+) and dual supply ±4.5V ~ 20V (V±).
