Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5063CASA-T is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-bridge topology with independent channel control
• Number of Drivers: Dual-channel configuration (2 drivers)
• Gate Type: N-channel MOSFET driving capability
• Supply Voltage Range: 8V to 12.6V operation
• Peak Output Current: 2A source and 2A sink capability
• Input Logic Type: Non-inverting input configuration
• Bootstrap Voltage Rating: 125V maximum
• Package Compatibility: 8-SOIC with exposed pad (8-SOIC-EP)
• Operating Temperature Range: -40°C to 150°C junction temperature

The MAX5063CASA+T qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format: the original part uses tube packaging, while the substitute uses tape and reel (TR) format. Both parts share the same base product number (MAX5063) and maintain full functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MAX5063CASA+T is the appropriate selection for applications currently using or requiring the MAX5063CASA-T. The substitute part maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring long-term availability and supply chain continuity. Both parts carry ROHS3 compliance and identical moisture sensitivity ratings, confirming environmental and regulatory compatibility.

The transition from tube to tape and reel packaging does not affect electrical performance or mechanical fit within standard surface-mount assembly processes. The active status of the MAX5063CASA+T provides superior availability compared to the obsolete MAX5063CASA-T, making it the preferred choice for new production and design transitions.

Frequently Asked Questions (FAQ)

Q: Are the MAX5063CASA-T and MAX5063CASA+T electrically identical?

A: Yes. Both parts share identical electrical specifications including supply voltage range (8V–12.6V), output current ratings (2A source/sink), input logic levels, bootstrap voltage rating (125V), and switching characteristics (65ns rise/fall time). They are functionally equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The MAX5063CASA-T uses tube packaging, while the MAX5063CASA+T uses tape and reel (TR) format. This distinction affects only the delivery and handling method, not the device itself.

Q: Can I use MAX5063CASA+T in place of MAX5063CASA-T in existing designs?

A: Yes. The parts are pin-compatible, mechanically compatible in the 8-SOIC-EP package, and electrically identical. No circuit modifications are required.

Q: Why is the original part marked as obsolete?

A: The MAX5063CASA-T is classified as obsolete by the manufacturer. The MAX5063CASA+T remains in active production, providing a direct path for design continuity and supply chain management.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, identical moisture sensitivity levels (MSL 1), and equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001).

Q: What is the bootstrap voltage rating used for?

A: The 125V bootstrap voltage rating specifies the maximum voltage that can be applied across the high-side gate driver supply and ground reference. This parameter is critical for half-bridge applications where the high-side driver floats above the switching node.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts operate across the temperature range of -40°C to 150°C junction temperature, supporting industrial and automotive thermal environments within this specification.
