MAX3120ESA Equivalent & Substitute Parts

Part Overview

The MAX3120ESA is a full-duplex infrared (IrDA) transceiver interface IC manufactured by Analog Devices Inc./Maxim Integrated. This device integrates a single driver and receiver pair for IrDA protocol communication at 235 Kbps, operating across a 3V to 5.5V supply voltage range. The component is housed in an 8-SOIC surface-mount package.

The MAX3120ESA is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design requirements favor active, currently-manufactured alternatives with improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX3120ESA is determined by strict equivalence across the following electrical and mechanical parameters:

• Protocol: Infrared (IrDA)
• Number of Drivers/Receivers: 1/1 configuration
• Duplex Mode: Full-duplex operation
• Data Rate: 235 Kbps
• Supply Voltage Range: 3V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 8-SOIC form factor
• Mounting Technology: Surface Mount

The MAX3120ESA+ qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction lies in product status and compliance certifications rather than functional or physical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MAX3120ESA+ serves as the direct functional equivalent to the MAX3120ESA. Both components share identical electrical performance specifications and physical packaging, ensuring pin-for-pin compatibility and equivalent circuit behavior.

The MAX3120ESA+ is classified as an active product with ROHS3 compliance certification, whereas the MAX3120ESA is obsolete and RoHS non-compliant. For new designs or production runs requiring regulatory compliance with current environmental standards, the MAX3120ESA+ is the appropriate selection. For legacy system maintenance or applications where RoHS compliance is not mandated, either component may be used interchangeably from a functional standpoint.

Both components maintain identical REACH and ECCN classifications, indicating equivalent regulatory treatment for export and environmental impact purposes.

Frequently Asked Questions (FAQ)
