MAX186ACWP Equivalent & Substitute Parts

Part Overview

The MAX186ACWP is a 12-bit data acquisition system (DAS) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This device features 8 channels, a 133k samples-per-second sampling rate, and serial data interface capability in a 20-SOIC surface mount package. The MAX186ACWP is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support, production continuity, and system maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX186ACWP is determined by strict equivalence across the following critical parameters:

• Number of Channels: 8 channels (fixed requirement)
• Resolution: 12 bits (fixed requirement)
• Sampling Rate: 133k samples per second (fixed requirement)
• Package / Case: 20-SOIC (0.295", 7.50mm Width) (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Voltage Supply Source: Dual ± (fixed requirement)
• Operating Temperature Range: 0°C to 70°C (fixed requirement)

The MAX186ACWP+ qualifies as a direct substitute because it maintains identical electrical specifications and mechanical compatibility across all critical parameters. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX186ACWP+ is the direct substitute for the MAX186ACWP. Both components share identical electrical and mechanical specifications across all critical parameters: 8-channel configuration, 12-bit resolution, 133k sampling rate, dual ± supply voltage, and 20-SOIC package footprint.

The MAX186ACWP+ is classified as an active product, ensuring ongoing availability and manufacturing support. The MAX186ACWP+ achieves ROHS3 compliance, whereas the original MAX186ACWP is RoHS non-compliant. Both components maintain REACH Unaffected status and identical moisture sensitivity levels.

The MAX186ACWP+ supports expanded data interface options (MICROWIRE™, QSPI™, Serial, SPI™) compared to the serial-only interface of the MAX186ACWP. This expanded interface capability provides additional design flexibility without compromising backward compatibility for serial-based implementations.

Frequently Asked Questions (FAQ)

Q: Can the MAX186ACWP+ directly replace the MAX186ACWP in existing designs?

A: Yes. The MAX186ACWP+ maintains identical electrical specifications (8 channels, 12-bit resolution, 133k sampling rate, dual ± supply) and mechanical compatibility (20-SOIC package, surface mount). The expanded data interface options of the MAX186ACWP+ do not affect serial-based implementations.

Q: What is the primary reason to transition from MAX186ACWP to MAX186ACWP+?

A: The MAX186ACWP is obsolete, while the MAX186ACWP+ is an active product with ongoing manufacturing support. The MAX186ACWP+ also achieves ROHS3 compliance, addressing regulatory requirements for new designs and production continuity.

Q: Are there any package or footprint differences between these components?

A: No. Both the MAX186ACWP and MAX186ACWP+ use the identical 20-SOIC (0.295", 7.50mm Width) package with surface mount configuration. PCB layouts and assembly processes require no modification.

Q: Does the MAX186ACWP+ support the same operating temperature range?

A: Yes. Both components operate across the 0°C to 70°C temperature range with identical moisture sensitivity levels (MSL 1, Unlimited).

Q: What additional data interfaces does the MAX186ACWP+ provide?

A: The MAX186ACWP+ supports MICROWIRE™, QSPI™, Serial, and SPI™ interfaces. The original MAX186ACWP supports serial interface only. Designs using serial communication remain fully compatible without modification.
