MAX186DEWP+ Equivalent & Substitute Parts

Part Overview

The MAX186DEWP+ is a 12-bit Data Acquisition System (DAS) with analog-to-digital conversion capability, manufactured by Analog Devices Inc./Maxim Integrated. This component features 8 channels, a 133 kHz sampling rate, and supports multiple serial communication interfaces including MICROWIRE™, QSPI™, and SPI™. The device operates on dual ±5V supply and is housed in a 20-SOIC surface mount package. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the MAX186DEWP+ serves applications requiring multi-channel data acquisition with moderate resolution and sampling rates. Identifying equivalent parts is essential for supply chain continuity, design flexibility, and procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX186DEWP+ is determined by strict equivalence across the following critical parameters:

• Channel Configuration: 8 channels
• Resolution: 12 bits
• Sampling Rate: 133 kHz
• Serial Interface Support: MICROWIRE™, QSPI™, Serial, SPI™
• Supply Voltage: Dual ±5V
• Package Type: 20-SOIC surface mount
• Operating Temperature Range: -40°C to 85°C
• Product Status: Active
• Compliance: ROHS3 Compliant

Only parts meeting all these parameters qualify as direct substitutes. Deviations in any parameter—including channel count, resolution, sampling rate, interface protocol, supply voltage, or package configuration—disqualify a part from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The MAX186DEWP+ maintains active product status with full ROHS3 compliance and REACH unaffected classification, ensuring regulatory compliance for current and future applications. The unlimited moisture sensitivity rating (MSL 1) permits unrestricted storage and handling without time-based constraints. Selection of equivalent parts should prioritize components with identical active status and matching compliance certifications to maintain design integrity and supply chain reliability. The ECCN classification (EAR99) and HTSUS code (8542.39.0001) remain consistent across equivalent parts, simplifying procurement and export documentation.

Frequently Asked Questions (FAQ)

Q: What makes a part a direct substitute for the MAX186DEWP+? A: A direct substitute must match all critical parameters: 8-channel configuration, 12-bit resolution, 133 kHz sampling rate, support for MICROWIRE™, QSPI™, Serial, and SPI™ interfaces, dual ±5V supply, 20-SOIC package, -40°C to 85°C operating range, and active product status with ROHS3 compliance.

Q: Can I use a part with different channel count or resolution? A: No. Deviations in channel count, resolution, or sampling rate result in functional incompatibility and disqualify a part from direct substitution.

Q: Does the 20-SOIC package dimension affect substitution? A: Yes. The package specification (20-SOIC, 0.295" width, 7.50mm) is a critical parameter. Parts in alternative packages are not direct substitutes.

Q: What is the significance of the MSL 1 rating? A: MSL 1 (Unlimited) indicates no moisture sensitivity constraints. The component can be stored and handled without time-based precautions, simplifying logistics and inventory management.

Q: Are there any interface protocol considerations for substitution? A: The MAX186DEWP+ supports multiple serial interfaces (MICROWIRE™, QSPI™, Serial, SPI™). Direct substitutes must support all four protocols to ensure compatibility with existing designs.

Q: How does ROHS3 compliance affect part selection? A: ROHS3 compliance is mandatory for equivalent parts to ensure regulatory alignment and design consistency. Non-compliant alternatives introduce compliance risk and are not acceptable substitutes.
