Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX186DEWP is determined by strict equivalence across the following critical parameters:

• Number of Channels: 8 channels
• Resolution: 12 bits
• Sampling Rate: 133k samples per second
• Package Type: 20-SOIC form factor
• Mounting Type: Surface mount
• Operating Temperature Range: -40°C to 85°C
• Voltage Supply Configuration: Dual ±

The MAX186DEWP+ qualifies as a direct substitute based on matching all electrical specifications and physical packaging requirements. The primary distinction is product status and compliance certification, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

The MAX186DEWP+ is the direct functional equivalent of the MAX186DEWP. Selection between these parts should be based on the following criteria:

For legacy system maintenance and repair of existing MAX186DEWP installations, the MAX186DEWP+ provides identical electrical performance and pinout compatibility within the same 20-SOIC package.

For new designs, the MAX186DEWP+ is the appropriate choice due to its active product status and ROHS3 compliance certification. The obsolete status of the MAX186DEWP restricts its use to replacement applications only.

The MAX186DEWP+ supports expanded data interface options (MICROWIRE™, QSPI™, SPI™) in addition to the serial interface, providing greater design flexibility without compromising core specifications.

Frequently Asked Questions (FAQ)

Q: Can MAX186DEWP+ directly replace MAX186DEWP in existing designs?

A: Yes. Both devices share identical channel count (8), resolution (12 bits), sampling rate (133k), operating temperature range (-40°C to 85°C), and 20-SOIC package configuration. Pinout and electrical specifications are compatible.

Q: What is the primary difference between MAX186DEWP and MAX186DEWP+?

A: The MAX186DEWP+ is an active product with ROHS3 compliance, while the MAX186DEWP is obsolete and RoHS non-compliant. The MAX186DEWP+ also supports additional serial interface protocols (MICROWIRE™, QSPI™, SPI™) beyond the basic serial interface of the original part.

Q: Are there packaging differences between these parts?

A: No. Both devices use identical 20-SOIC (0.295", 7.50mm Width) surface mount packaging. PCB layout and assembly processes remain unchanged.

Q: What is the moisture sensitivity level for both parts?

A: Both the MAX186DEWP and MAX186DEWP+ have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Is the MAX186DEWP+ suitable for new product designs?

A: Yes. The MAX186DEWP+ is the recommended choice for new designs. Its active product status ensures long-term availability and support, and ROHS3 compliance meets current regulatory requirements.
