Substitute Part Grouping Explanation

Substitution of the MAX4493AXK-T is determined by strict equivalence across all electrical and mechanical parameters. The substitute relationship is based on the following criteria:

Electrical Parameter Equivalence:

• Amplifier type: General Purpose
• Number of circuits: 1
• Output configuration: Rail-to-Rail
• Slew rate: 3 V/µs
• Gain bandwidth product: 5 MHz
• Input bias current: 200 nA
• Input offset voltage: 300 µV
• Supply current: 770 µA
• Output current per channel: 15 mA
• Supply voltage range: 4.5 V to 11 V
• Operating temperature: -40°C to 125°C

Mechanical Parameter Equivalence:

• Package type: 5-TSSOP, SC-70-5, SOT-353
• Mounting: Surface Mount
• Supplier device package: SC-70-5

Compliance Equivalence:

• RoHS3 compliance
• Moisture sensitivity level 1
• REACH unaffected status

The MAX4493AXK+T qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format (Tape & Reel versus individual unit) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MAX4493AXK+T is a direct functional and electrical equivalent to the MAX4493AXK-T. Selection between these components should be based on the following factors:

Product Status Consideration: The MAX4493AXK-T is classified as obsolete, while the MAX4493AXK+T maintains active product status. For new designs and ongoing production requiring long-term component availability, the MAX4493AXK+T is the appropriate selection.

Packaging Format: The MAX4493AXK-T is supplied as individual units, while the MAX4493AXK+T is supplied in Tape & Reel format. Procurement volume and assembly process requirements determine the optimal packaging selection. Tape & Reel packaging is standard for automated surface mount assembly operations.

Compliance and Certification: Both components maintain identical RoHS3 compliance, moisture sensitivity level 1, and REACH unaffected status. No compliance-related restrictions apply to substitution.

Inventory and Lead Time: The MAX4493AXK+T has higher current inventory (3600 Pcs) compared to the MAX4493AXK-T (3205 Pcs), supporting improved supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MAX4493AXK+T directly replace the MAX4493AXK-T in existing circuit designs?

A: Yes. The MAX4493AXK+T is electrically and mechanically equivalent to the MAX4493AXK-T across all specified parameters. No circuit modifications are required for substitution.

Q: What is the difference between MAX4493AXK-T and MAX4493AXK+T?

A: The primary differences are product status and packaging format. The MAX4493AXK-T is obsolete and supplied as individual units. The MAX4493AXK+T is active and supplied in Tape & Reel format. All electrical specifications and package dimensions are identical.

Q: Are there any temperature or supply voltage limitations when using the MAX4493AXK+T as a substitute?

A: No. Both components operate across the identical temperature range (-40°C to 125°C) and supply voltage range (4.5 V to 11 V). No operational limitations apply to substitution.

Q: Does the Tape & Reel packaging of the MAX4493AXK+T affect circuit performance?

A: No. Tape & Reel packaging is a supply format only. The individual component specifications, electrical performance, and package dimensions remain unchanged. Tape & Reel format is standard for automated assembly processes.

Q: Are both components RoHS compliant?

A: Yes. Both the MAX4493AXK-T and MAX4493AXK+T are ROHS3 compliant with moisture sensitivity level 1 (unlimited). No environmental or regulatory restrictions apply to either component.

Q: What is the base product number for these components?

A: The base product number is MAX4493. Both the MAX4493AXK-T and MAX4493AXK+T are variants of this base product, differentiated by packaging and product status.
