MAX160EWN Equivalent & Substitute Parts

Part Overview

The MAX160EWN is an 8-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for single-ended input data acquisition applications. This component features a Successive Approximation Register (SAR) architecture with a 250 kSPS sampling rate and operates from dual 5V supply rails. The MAX160EWN is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where this legacy component is specified.

Substitute Part Grouping Explanation

Substitution of the MAX160EWN is determined by strict equivalence across the following critical parameters:

• Resolution & Sampling Rate: 8-bit resolution at 250 kSPS
• Input Configuration: Single-ended input, single channel
• Interface & Architecture: Parallel data interface with SAR topology
• Supply Voltages: Dual 5V analog and digital supplies
• Package Compatibility: 18-SOIC surface mount form factor
• Temperature Range: -40°C to 85°C operating specification

The MAX160EWN+ meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is product status and compliance certification, not electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MAX160EWN+ is the direct substitute for the MAX160EWN. Both components are electrically and mechanically identical across all functional parameters. Selection between these parts should be based on the following criteria:

For Legacy System Maintenance: The MAX160EWN remains available in inventory (2000 pcs) and is suitable for direct replacement in existing designs where the component is already qualified and in production.

For New Designs and Compliance Requirements: The MAX160EWN+ is the preferred selection. This part carries Active product status, ensuring long-term availability and manufacturer support. The MAX160EWN+ achieves ROHS3 compliance, meeting current environmental and regulatory standards, whereas the MAX160EWN is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications.

Packaging Consideration: The MAX160EWN+ is supplied in Tube packaging, while the MAX160EWN packaging specification is not detailed. Verify packaging requirements for your assembly process.

Frequently Asked Questions (FAQ)

Q: Are the MAX160EWN and MAX160EWN+ pin-for-pin compatible?

A: Yes. Both components use the 18-SOIC package with identical pinout, electrical characteristics, and mechanical dimensions (0.295" width, 7.50mm). Direct PCB substitution is possible without layout modifications.

Q: What is the difference between MAX160EWN and MAX160EWN+?

A: The parts are functionally equivalent. The primary differences are: (1) Product Status—MAX160EWN is Obsolete while MAX160EWN+ is Active; (2) RoHS Compliance—MAX160EWN+ is ROHS3 compliant while MAX160EWN is non-compliant; (3) Packaging—MAX160EWN+ is supplied in Tube format.

Q: Can I use MAX160EWN+ in a design originally specified for MAX160EWN?

A: Yes. The MAX160EWN+ is a direct functional equivalent with identical electrical performance, supply requirements, sampling rate, resolution, and package footprint. The Active status and improved compliance of the MAX160EWN+ make it suitable for both legacy system support and new production.

Q: Why is the MAX160EWN classified as Obsolete?

A: The MAX160EWN has reached end-of-life status. The MAX160EWN+ represents the current production equivalent and is recommended for all new designs and ongoing procurement.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both components operate across the identical temperature range (-40°C to 85°C) and maintain the same Moisture Sensitivity Level (MSL 1 - Unlimited). Environmental performance is equivalent.

Q: What supply voltages are required for the MAX160EWN+?

A: The MAX160EWN+ requires dual 5V supplies: 5V for analog circuitry and 5V for digital logic. This matches the MAX160EWN specification exactly.
