Substitute Part Grouping Explanation
Substitution of the MAX186CCAP is determined by strict equivalence across the following critical parameters:
- Channel Count: 8 channels (exact match required)
- Resolution: 12 bits (exact match required)
- Sampling Rate: 133k samples per second (exact match required)
- Package Type: 20-SSOP with identical physical dimensions (exact match required)
- Voltage Supply Architecture: Dual ± supply configuration (exact match required)
- Operating Temperature Range: 0°C to 70°C (exact match required)
- Mounting Technology: Surface Mount (exact match required)
The MAX186CCAP+ qualifies as a direct substitute based on full alignment with all specified electrical and mechanical parameters. Both devices share identical channel architecture, resolution, sampling performance, and physical packaging specifications.

Engineering Selection Recommendations
The MAX186CCAP+ is the direct equivalent substitute for the MAX186CCAP. Selection of the MAX186CCAP+ is supported by the following factors:
- Product Status: The MAX186CCAP+ maintains active production status, ensuring long-term component availability and supply chain continuity.
- Regulatory Compliance: The MAX186CCAP+ achieves ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the original MAX186CCAP is non-compliant.
- Electrical Equivalence: Both devices maintain identical channel count, resolution, sampling rate, and dual ± supply architecture.
- Physical Compatibility: Identical 20-SSOP packaging ensures direct PCB layout compatibility without redesign.
- Interface Capability: The MAX186CCAP+ supports expanded serial interface options (MICROWIRE™, QSPI™, SPI™) while maintaining backward compatibility with the serial interface of the original part.
Frequently Asked Questions (FAQ)
Q: Can the MAX186CCAP+ be used as a direct replacement for the MAX186CCAP in existing designs?
A: Yes. The MAX186CCAP+ is electrically and mechanically equivalent. Both devices feature 8 channels, 12-bit resolution, 133k sampling rate, and identical 20-SSOP packaging. No PCB modifications are required.
Q: What is the primary difference between the MAX186CCAP and MAX186CCAP+?
A: The MAX186CCAP+ is the active production variant with ROHS3 compliance and expanded serial interface support (MICROWIRE™, QSPI™, SPI™). The original MAX186CCAP is obsolete and RoHS non-compliant.
Q: Are there any compatibility concerns with the expanded interface options on the MAX186CCAP+?
A: No. The MAX186CCAP+ maintains full backward compatibility with serial interface implementations. The additional interface protocols (MICROWIRE™, QSPI™, SPI™) are optional and do not affect existing serial-based designs.
Q: Does the MAX186CCAP+ require different supply voltage specifications?
A: Both devices operate on a dual ± supply architecture. The MAX186CCAP+ specifies ±5V operation. Verify that your existing power supply design meets this requirement.
Q: Is the 20-SSOP package identical between both parts?
A: Yes. Both the MAX186CCAP and MAX186CCAP+ use the 20-SSOP package with 0.209" width and 5.30mm dimensions. Pin-for-pin compatibility is maintained.
Q: What is the moisture sensitivity level for both parts?
A: Both devices have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
