Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX620CWN is determined by strict equivalence across the following critical parameters:

• Driven configuration (High-Side)
• Number of independent drivers (4 channels)
• Gate type (N-Channel MOSFET)
• Input logic type (Non-Inverting)
• Supply voltage range (4.5V ~ 16.5V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.4V)
• Rise and fall time specifications (1.7µs, 2.5µs typical)
• Operating temperature range (0°C ~ 70°C)
• Package form factor (18-SOIC)
• Mounting technology (Surface Mount)

The MAX620CWN+ qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications. The primary distinction between these parts is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX620CWN+ is the direct functional equivalent of the MAX620CWN. Selection between these parts should be based on the following criteria:

Product Status: The MAX620CWN is classified as obsolete, while the MAX620CWN+ maintains active product status. For new designs or long-term production requirements, the MAX620CWN+ provides assured supply chain continuity.

Compliance Requirements: The MAX620CWN+ is ROHS3 compliant, whereas the MAX620CWN is RoHS non-compliant. Applications subject to RoHS directives or customer compliance mandates require the MAX620CWN+.

Electrical and Mechanical Compatibility: Both parts are electrically and mechanically interchangeable. Pin configuration, package dimensions, and functional performance are identical across all specified parameters.

Packaging Consideration: The MAX620CWN+ is supplied in tube packaging, which may affect procurement logistics and handling procedures compared to the original part specification.
