Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX5063DASA is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology
• Number of Drivers: 2 independent channels
• Gate Type: N-Channel MOSFET
• Supply Voltage Range: 8V ~ 12.6V
• Logic Voltage Thresholds: VIL 0.8V, VIH 2V
• Peak Output Current: 2A source and sink capability
• Input Configuration: Inverting and non-inverting inputs
• Bootstrap Voltage Rating: 125V maximum
• Switching Performance: 65ns rise and fall times
• Package Compatibility: 8-SOIC with exposed pad
• Environmental Compliance: ROHS3 compliance and MSL Level 1

The substitute part MAX5063DASA+ meets all these parameters identically, differing only in product status (active vs. obsolete) and packaging format (tube vs. unspecified).

Parameter Comparison

Engineering Selection Recommendations

The MAX5063DASA+ is a direct functional equivalent to the MAX5063DASA. Both parts share identical electrical specifications, thermal ratings, and package geometry. The primary distinction is product lifecycle status: MAX5063DASA is obsolete, while MAX5063DASA+ is active.

For new designs or production continuity, MAX5063DASA+ is the appropriate selection. Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The tube packaging format of MAX5063DASA+ supports automated assembly processes without additional handling requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX5063DASA+ be used as a direct replacement for MAX5063DASA?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The substitution is direct with no circuit modifications required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status indicates lifecycle phase. The obsolete MAX5063DASA may have limited availability and no manufacturer support. The active MAX5063DASA+ ensures ongoing supply, technical support, and compliance with current manufacturing standards.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 8-SOIC package with exposed pad (8-SOIC-EP) with identical dimensions (0.154" width, 3.90mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both MAX5063DASA and MAX5063DASA+ are ROHS3 compliant with MSL Level 1 rating. They meet identical environmental and regulatory requirements.

Q: What is the difference between tube and unspecified packaging?

A: Tube packaging is a standard format for automated component handling and placement. The unspecified packaging of MAX5063DASA may refer to alternative formats. For production environments, tube packaging (MAX5063DASA+) is preferred for assembly efficiency.

Q: Are the electrical characteristics identical between the two parts?

A: Yes. Supply voltage range (8V ~ 12.6V), output current (2A source/sink), logic thresholds (0.8V/2V), bootstrap voltage (125V), and switching times (65ns) are identical for both parts.
