Substitute Part Grouping Explanation

Substitution of the DMP4026LSS-13 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• FET channel type (P-Channel)
• Drain-to-source voltage rating (40V)
• Continuous drain current capability (7.2A @ 25°C)
• On-state resistance (25 mOhm @ 3A, 10V)
• Gate threshold voltage (1.8V @ 250µA)
• Power dissipation rating (1.5W)
• Operating temperature range (-55°C to 150°C)

Mechanical & Packaging Specifications:

• Package type (8-SOIC with 0.154" / 3.90mm width)
• Surface mount configuration
• Tape & Reel packaging format

Compliance & Environmental:

• ROHS3 compliance
• Moisture sensitivity level (MSL 1)
• REACH unaffected status

The substitute part DMP4026LSSQ-13 meets all electrical and mechanical parameters identical to the main part. The primary distinction is the addition of automotive-grade qualification (AEC-Q101) in the substitute part, which represents an enhanced qualification level rather than a deviation from base specifications.
