MAX186BEAP Equivalent & Substitute Parts

Part Overview

The MAX186BEAP is a 12-bit Data Acquisition System (DAS) with 8 channels, 133k sampling rate, and serial data interface, manufactured by Analog Devices Inc./Maxim Integrated. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs. The MAX186BEAP operates across a temperature range of -40°C to 85°C and is packaged in a 20-SSOP surface mount configuration.

Substitute Part Grouping Explanation

Substitution of the MAX186BEAP is determined by strict equivalence across the following critical parameters:

• Channel Count: 8 channels (fixed requirement)
• Resolution: 12 bits (fixed requirement)
• Sampling Rate: 133k samples per second (fixed requirement)
• Package Type: 20-SSOP with identical physical dimensions (fixed requirement)
• Operating Temperature Range: -40°C to 85°C (fixed requirement)
• Voltage Supply Architecture: Dual ± supply configuration (fixed requirement)

The MAX186BEAP+ qualifies as a direct substitute based on matching all electrical and mechanical parameters. The primary distinction is product status and compliance certification, not functional capability.

Engineering Selection Recommendations

The MAX186BEAP+ is the direct functional equivalent for MAX186BEAP applications. Selection between these parts is determined by regulatory and compliance requirements rather than electrical performance:

For new designs and systems requiring regulatory compliance: MAX186BEAP+ is the appropriate selection. This part maintains active product status and meets ROHS3 compliance requirements, ensuring long-term availability and regulatory alignment.

For legacy system maintenance: MAX186BEAP remains compatible with existing designs due to identical electrical specifications and package geometry. However, MAX186BEAP+ is preferred where supply chain continuity is a consideration, as the obsolete MAX186BEAP has limited inventory availability.

Both parts share identical core specifications: 8-channel, 12-bit resolution, 133k sampling rate, dual ± supply architecture, and 20-SSOP packaging. The MAX186BEAP+ provides expanded serial interface options (MICROWIRE™, QSPI™, SPI™) in addition to the base serial interface, offering enhanced protocol flexibility without compromising backward compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX186BEAP+ directly replace MAX186BEAP in existing circuits?

A: Yes. Both parts share identical electrical specifications, supply requirements, operating temperature range, and 20-SSOP package dimensions. Pin-for-pin compatibility is maintained.

Q: What is the primary difference between MAX186BEAP and MAX186BEAP+?

A: Product status and compliance certification. MAX186BEAP is obsolete and RoHS non-compliant. MAX186BEAP+ is active production and ROHS3 compliant. The MAX186BEAP+ also supports additional serial interface protocols (MICROWIRE™, QSPI™, SPI™) alongside the base serial interface.

Q: Are there any performance differences in sampling rate or resolution?

A: No. Both parts deliver identical 12-bit resolution and 133k sampling rate performance.

Q: What packaging options are available?

A: Both parts are supplied in 20-SSOP surface mount packages with 0.209" width and 5.30mm physical dimensions. MAX186BEAP+ is available in Tube packaging.

Q: Which part should be selected for new product development?

A: MAX186BEAP+ is the appropriate selection for new designs. Active product status ensures ongoing availability and support, and ROHS3 compliance meets current regulatory requirements.

Q: Are the supply voltage requirements identical?

A: Yes. Both parts require dual ± supply architecture with ±5V specification for MAX186BEAP+. Voltage supply source configuration is identical.
