Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX630CSA are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution compatibility are:

• Topology: Boost (Step-Up) configuration
• Output Configuration: Positive adjustable output
• Input Voltage Range: 2.2V to 16.5V minimum compatibility
• Output Voltage Range: 2.2V to 18V minimum capability
• Output Current: 525mA or greater
• Switching Frequency: 40kHz operation
• Package: 8-SOIC form factor with identical pinout
• Number of Outputs: Single output configuration

The MAX630CSA+ qualifies as a direct substitute based on identical electrical specifications and package compatibility. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX630CSA+ is the direct substitute for the MAX630CSA. Both parts share identical electrical specifications and package configurations, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

The MAX630CSA+ offers two significant advantages over the obsolete MAX630CSA:

1. Active product status ensures continued availability and manufacturer support
2. ROHS3 compliance certification meets current environmental and regulatory requirements, whereas the MAX630CSA is RoHS non-compliant

For new designs or component replenishment, the MAX630CSA+ is the appropriate selection. The electrical performance, thermal characteristics, and mechanical form factor remain unchanged, requiring no circuit modifications or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can MAX630CSA+ be used as a direct replacement for MAX630CSA?

A: Yes. The MAX630CSA+ is electrically and mechanically identical to the MAX630CSA. Both parts operate as boost regulators with 525mA output current, 40kHz switching frequency, and 8-SOIC packaging. No circuit modifications are required.

Q: What is the primary reason to transition from MAX630CSA to MAX630CSA+?

A: The MAX630CSA is obsolete, while MAX630CSA+ maintains active product status. Additionally, MAX630CSA+ is ROHS3 compliant, meeting current environmental regulations, whereas MAX630CSA is RoHS non-compliant.

Q: Are the package dimensions identical between both parts?

A: Yes. Both the MAX630CSA and MAX630CSA+ use the 8-SOIC package with 0.154" width and 3.90mm body width. PCB footprints and component placement are identical.

Q: Does the MAX630CSA+ require different circuit design considerations?

A: No. The electrical specifications, output voltage range (2.2V to 18V), input voltage range (2.2V to 16.5V), and output current capability (525mA) are identical. Existing circuit designs require no modification.

Q: What is the operating temperature range for both parts?

A: Both the MAX630CSA and MAX630CSA+ operate across 0°C to 70°C ambient temperature range.
