Key Parameters

Substitute Part Grouping Explanation

The MAX186BCAP+ qualifies as a direct substitute based on the following critical parameters:

• Electrical Compatibility: Identical 12-bit resolution, 8-channel configuration, and 133k sampling rate
• Interface Compatibility: Serial data interface maintained; MAX186BCAP+ additionally supports MICROWIRE™, QSPI™, and SPI™ protocols
• Mechanical Compatibility: Identical 20-SSOP package footprint (0.209", 5.30mm Width) and surface mount configuration
• Thermal Compatibility: Matching operating temperature range of 0°C to 70°C
• Supply Voltage: Both require dual ± supply configuration
• Moisture Sensitivity: Identical MSL rating of 1 (Unlimited)

The substitution is based on functional equivalence within the MAX186 base product family, with the MAX186BCAP+ representing the active production variant.

Parameter Comparison

Engineering Selection Recommendations

The MAX186BCAP+ is the appropriate selection for new designs and system replacements. The obsolete status of the MAX186BCAP eliminates it from consideration for ongoing procurement. The MAX186BCAP+ maintains full electrical and mechanical compatibility while providing:

• Active product status with ongoing manufacturer support
• ROHS3 compliance, meeting current environmental regulations
• Enhanced serial protocol support (MICROWIRE™, QSPI™, SPI™) in addition to standard serial interface
• Specified supply voltage of ±5V, providing design clarity
• Identical package footprint enabling direct PCB substitution

Both components share identical REACH and ECCN classifications, confirming regulatory equivalence for export and supply chain purposes.

Frequently Asked Questions (FAQ)

Q: Can MAX186BCAP+ be used as a direct replacement for MAX186BCAP in existing designs?

A: Yes. The MAX186BCAP+ is electrically and mechanically compatible with the MAX186BCAP. Both components feature identical 12-bit resolution, 8-channel configuration, 133k sampling rate, 20-SSOP package footprint, and operating temperature range. The MAX186BCAP+ can be substituted without PCB modifications.

Q: What are the key differences between MAX186BCAP and MAX186BCAP+?

A: The primary differences are product status and compliance certifications. The MAX186BCAP is obsolete, while the MAX186BCAP+ is active. The MAX186BCAP+ is ROHS3 compliant, whereas the MAX186BCAP is RoHS non-compliant. The MAX186BCAP+ additionally supports MICROWIRE™, QSPI™, and SPI™ protocols alongside the standard serial interface. Supply voltage is specified as ±5V for the MAX186BCAP+.

Q: Are there packaging differences between these parts?

A: No. Both the MAX186BCAP and MAX186BCAP+ use the 20-SSOP package with identical dimensions (0.209", 5.30mm Width). Both are surface mount components with MSL rating of 1 (Unlimited).

Q: What is the significance of the ROHS3 compliance difference?

A: ROHS3 compliance indicates the MAX186BCAP+ meets current environmental regulations restricting hazardous substances. The MAX186BCAP's RoHS non-compliant status reflects its obsolete classification. For new designs and regulated applications, the MAX186BCAP+ is the required choice.

Q: Can both parts be used interchangeably in the same circuit?

A: Yes, within the constraints of product availability. The MAX186BCAP is obsolete and no longer in production. The MAX186BCAP+ is the active equivalent and should be used for all new designs and replacements. Both components operate within the same electrical and thermal specifications.
