MAX4466EXK-T Equivalent & Substitute Parts

Part Overview

The MAX4466EXK-T is a Class AB mono amplifier IC manufactured by Analog Devices Inc./Maxim Integrated, designed for microphone preamplification applications. The device is packaged in a 5-TSSOP (SC-70-5, SOT-353) surface mount configuration and operates across a 2.4V to 5.5V supply voltage range.

The MAX4466EXK-T carries an obsolete product status. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when design revisions require active, currently manufactured alternatives with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4466EXK-T is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Amplifier Type: Class AB
• Channel Configuration: 1-Channel (Mono)
• Supply Voltage Range: 2.4V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 5-TSSOP / SC-70-5 / SOT-353
• Mounting Type: Surface Mount
• Microphone feature support

The substitute part MAX4466EXK+T meets all electrical and mechanical requirements for direct substitution. The primary distinction between the main part and its substitute is product status (obsolete versus active) and packaging format (tape reel availability).

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Restocking: The MAX4466EXK+T is the appropriate selection for applications requiring the MAX4466 Class AB mono amplifier. This part is currently in active production status with substantial inventory availability (25,300 pieces), ensuring supply chain continuity. The MAX4466EXK+T maintains identical electrical specifications and package configuration as the obsolete MAX4466EXK-T.

Compliance Considerations: The MAX4466EXK+T achieves ROHS3 compliance, whereas the original MAX4466EXK-T does not. For applications subject to RoHS regulatory requirements, the substitute part satisfies compliance obligations while maintaining functional equivalence.

Packaging and Logistics: The MAX4466EXK+T is supplied in Cut Tape (CT) and Digi-Reel® formats, providing flexibility for both manual assembly and automated pick-and-place operations. The original MAX4466EXK-T packaging format is not specified in available data.

Frequently Asked Questions (FAQ)

Q: Can MAX4466EXK+T directly replace MAX4466EXK-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same Class AB amplifier topology, 1-channel mono configuration, 2.4V to 5.5V supply range, -40°C to 85°C operating temperature, and 5-TSSOP package. No circuit modifications are required.

Q: What is the difference between MAX4466EXK-T and MAX4466EXK+T?

A: The primary differences are product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and packaging format (standard versus Cut Tape/Digi-Reel). Electrical performance and pin configuration are identical.

Q: Is the 5-TSSOP package compatible with SC-70-5 and SOT-353 footprints?

A: Yes. The 5-TSSOP, SC-70-5, and SOT-353 designations refer to the same physical package. All three nomenclatures are equivalent and interchangeable on PCB layouts.

Q: Does the MAX4466EXK+T require different PCB layout considerations?

A: No. The MAX4466EXK+T uses the identical 5-TSSOP package footprint. Existing PCB designs require no modification.

Q: What is the moisture sensitivity level for both parts?

A: Both the MAX4466EXK-T and MAX4466EXK+T carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there inventory differences between the two parts?

A: Yes. The MAX4466EXK-T has 887 pieces available (obsolete status). The MAX4466EXK+T has 25,300 pieces in stock (active production), providing significantly greater availability for procurement.
