MAX4249ESD Equivalent & Substitute Parts

Part Overview

The MAX4249ESD is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, featuring dual circuits with push-pull, rail-to-rail output configuration in a 14-SOIC surface mount package. This device is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement continuity. The MAX4249ESD remains in limited inventory (2300 pcs) but active alternatives are available to ensure long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the MAX4249ESD is determined by strict equivalence across electrical and mechanical parameters. The primary substitute identified is the MAX4249ESD+, which maintains identical electrical specifications including slew rate (2.1 V/µs), gain bandwidth product (22 MHz), input bias current (0.1 pA), input offset voltage (70 µV), supply current (420 µA per dual channels), output current capability (68 mA per channel), and supply voltage range (2.4 V to 5.5 V). Both devices operate across the same temperature range (-40°C to 85°C) and utilize the identical 14-SOIC surface mount package.

The substitution logic is based on the following key parameters:

• Dual general-purpose amplifier configuration
• Push-pull, rail-to-rail output topology
• Identical electrical performance metrics
• Identical package and pinout (14-SOIC)
• Surface mount compatibility

Engineering Selection Recommendations

The MAX4249ESD+ is the direct functional equivalent of the MAX4249ESD, with complete electrical and mechanical compatibility. Selection between these parts should be based on the following criteria:

For new designs and long-term supply chain requirements: The MAX4249ESD+ is the preferred choice. This device carries Active product status, ensuring ongoing manufacturer support and availability. The MAX4249ESD+ is ROHS3 compliant, meeting current environmental and regulatory standards for commercial and industrial applications.

For legacy system maintenance: The MAX4249ESD remains available in limited inventory (2300 pcs) and may be selected for direct replacement in existing assemblies where RoHS non-compliance is not a constraint and immediate availability is critical.

Compliance considerations: The MAX4249ESD+ provides superior compliance posture with ROHS3 certification, while both devices maintain REACH Unaffected status and EAR99 export classification. Organizations subject to RoHS directives should prioritize the MAX4249ESD+.

Packaging and procurement: The MAX4249ESD+ is supplied in Tube packaging, which is standard for active production components. Inventory levels for MAX4249ESD+ (1355 pcs) support medium-term procurement planning.
