MAX3186EAP RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX3186EAP 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 operates across the industrial temperature range of -40°C to 85°C with a data rate of 230 kbps and supply voltage range of 4.5V to 5.5V.

The MAX3186EAP is classified as obsolete. Locating equivalent or substitute parts becomes necessary for ongoing production support, maintenance applications, or when original inventory becomes unavailable. The substitute identified maintains identical electrical and mechanical specifications while offering improved compliance status and active product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX3186EAP is determined by strict equivalence across the following critical parameters:

• Protocol specification (RS232)
• Driver and receiver configuration (5/3)
• Duplex operation mode (Full)
• Data rate capability (230 kbps minimum)
• Receiver hysteresis threshold (650 mV)
• Supply voltage compatibility (4.5V – 5.5V)
• Operating temperature range (-40°C to 85°C)
• Package and pinout compatibility (20-SSOP)
• Moisture sensitivity classification (MSL 1)

The MAX3186EAP+ meets all substitution criteria as a direct equivalent part. The primary distinction between these parts is product status and regulatory compliance, not functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The MAX3186EAP+ is the direct substitute for the obsolete MAX3186EAP. Both parts are electrically and mechanically identical across all functional parameters. Selection between these parts should be based on the following factors:

Product Status: The MAX3186EAP+ carries active product status with ongoing manufacturer support, whereas the MAX3186EAP is obsolete. For new designs or long-term production requirements, the MAX3186EAP+ is the appropriate choice.

Regulatory Compliance: The MAX3186EAP+ meets ROHS3 compliance requirements, while the MAX3186EAP is non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use the MAX3186EAP+.

Packaging: The MAX3186EAP+ is supplied in tube packaging, whereas the MAX3186EAP uses standard packaging. Tube packaging may affect handling and storage procedures but does not impact electrical performance or PCB assembly compatibility.

Availability: The MAX3186EAP+ maintains active inventory status (768 pcs), ensuring supply chain continuity. The MAX3186EAP, classified as obsolete, has limited remaining inventory (1050 pcs) with no guarantee of future availability.

Frequently Asked Questions (FAQ)

Q: Can MAX3186EAP+ be used as a direct replacement for MAX3186EAP in existing designs?

A: Yes. The MAX3186EAP+ is a direct functional equivalent. All electrical specifications, pin configurations, and package dimensions are identical. No circuit modifications or PCB redesign is required.

Q: What is the difference between MAX3186EAP and MAX3186EAP+?

A: The parts are functionally identical. Differences exist only in product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (standard vs. tube). Electrical and mechanical specifications are unchanged.

Q: Does the tube packaging of MAX3186EAP+ affect PCB assembly compatibility?

A: No. Tube packaging is a supply format only and does not affect component performance, pinout, or assembly compatibility. Standard pick-and-place equipment handles tube-packaged components without modification.

Q: Are there any temperature or voltage derating considerations when substituting MAX3186EAP with MAX3186EAP+?

A: No. Both parts operate identically across the full -40°C to 85°C temperature range and 4.5V to 5.5V supply voltage range. No derating or operational adjustments are necessary.

Q: What is the MSL rating for both parts, and does it affect storage?

A: Both MAX3186EAP and MAX3186EAP+ carry MSL 1 (Unlimited) classification, indicating unlimited shelf life without moisture sensitivity concerns. Standard component storage conditions apply.

Q: Is the MAX3186EAP+ suitable for applications requiring RoHS compliance?

A: Yes. The MAX3186EAP+ is ROHS3 compliant and meets all RoHS directive requirements. The original MAX3186EAP is non-compliant and cannot be used in RoHS-regulated applications.
