Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP131-29WL-7 is determined by the following critical parameters:

• Output voltage specification (2.9V fixed)
• Maximum output current capability (300mA)
• Maximum input voltage rating (5.5V)
• Dropout voltage performance (0.5V @ 300mA)
• Package type (SOT-25 / SC-74A, SOT-753)
• Mounting configuration (Surface Mount)
• Operating temperature range (-40°C ~ 85°C)

Parts meeting all these electrical and mechanical specifications are classified as direct equivalents. The AP131-29WG-7 satisfies all substitution criteria while offering the advantage of active product status.

Parameter Comparison

Engineering Selection Recommendations

The AP131-29WG-7 is the direct equivalent for the obsolete AP131-29WL-7. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications and package configurations. The primary distinction is product status: the AP131-29WG-7 maintains active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part.
