MAX3186CAP RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX3186CAP is a full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for serial communication applications requiring 5 drivers and 3 receivers in a compact 20-SSOP surface mount package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new design implementations. The part operates within a 4.5V to 5.5V supply voltage range and supports data rates up to 230kbps, making it suitable for legacy industrial and telecommunications equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX3186CAP is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS232 full-duplex transceiver functionality
• Driver/Receiver Configuration: 5 drivers and 3 receivers
• Electrical Specifications: 4.5V to 5.5V supply voltage, 230kbps data rate, 650 mV receiver hysteresis
• Package Compatibility: 20-SSOP surface mount package with identical pinout and mechanical dimensions
• Thermal Range: 0°C to 70°C operating temperature

The MAX3186CAP+ meets all these criteria as a parametric equivalent, with the primary distinction being its active product status and improved RoHS compliance profile. Both parts share identical electrical performance characteristics and package specifications, enabling direct substitution in applications where the original component is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The MAX3186CAP+ is the direct parametric equivalent for the obsolete MAX3186CAP. Selection between these parts should be based on the following factors:

For Legacy System Maintenance: The MAX3186CAP remains suitable for existing installations where component availability and cost are primary considerations. However, stock depletion of this obsolete part necessitates transition planning.

For New Designs and System Upgrades: The MAX3186CAP+ is the recommended selection due to its active product status, ensuring long-term availability and supply chain stability. The ROHS3 compliance of the MAX3186CAP+ aligns with current regulatory requirements and environmental standards, whereas the original MAX3186CAP does not meet these compliance criteria.

Compliance Considerations: Organizations subject to RoHS directives or environmental regulations should prioritize the MAX3186CAP+ to ensure regulatory compliance in manufacturing and end-of-life product management.

Packaging and Logistics: The MAX3186CAP+ is supplied in Tube packaging, which may differ from the original component's packaging specification. Verify that tube packaging is compatible with your assembly and handling processes.

Frequently Asked Questions (FAQ)

Q: Can the MAX3186CAP+ be used as a direct replacement for the MAX3186CAP in existing designs?

A: Yes. The MAX3186CAP+ is a parametric equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between MAX3186CAP and MAX3186CAP+?

A: The primary differences are product status and compliance certification. The MAX3186CAP is obsolete and RoHS non-compliant, while the MAX3186CAP+ is an active product with ROHS3 compliance. Electrical performance and package specifications are identical.

Q: Why is the MAX3186CAP classified as obsolete?

A: Obsolescence indicates that the manufacturer has discontinued production and support for this part number. The MAX3186CAP+ represents the current active equivalent in the product line.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate within the same voltage range (4.5V to 5.5V), support identical data rates (230kbps), maintain the same receiver hysteresis (650 mV), and function across the same operating temperature range (0°C to 70°C).

Q: What packaging options are available for the substitute part?

A: The MAX3186CAP+ is supplied in Tube packaging. Confirm that tube packaging is compatible with your assembly equipment and handling procedures before procurement.

Q: Is the 20-SSOP package identical between both parts?

A: Yes. Both parts use the 20-SSOP package with identical mechanical dimensions (0.209" width, 5.30mm). Pin assignments and footprints are identical, enabling direct PCB compatibility.

Q: What is the significance of RoHS3 compliance on the MAX3186CAP+?

A: ROHS3 compliance indicates adherence to the Restriction of Hazardous Substances Directive, which restricts the use of specific hazardous materials in electrical and electronic equipment. This certification is required for products sold in regulated markets and supports environmental and health protection objectives.
