Key Parameters

Substitute Part Grouping Explanation

The AP2191AMP-13 has one parametric equivalent substitute: AP2191MPG-13. This substitution is valid based on the following criteria:

Both parts share identical electrical specifications across all critical parameters: P-Channel output configuration, 1.5A maximum output current, 2.7V to 5.5V load voltage range, 95mOhm typical on-resistance, and identical fault protection features (current limiting, over-temperature, reverse current, and UVLO). Both devices are packaged in the 8-MSOP-EP package with exposed pad and operate across the same temperature range (-40°C to 85°C). Both maintain ROHS3 compliance and identical moisture sensitivity levels. The substitution is based strictly on matching electrical performance, package compatibility, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both AP2191AMP-13 and AP2191MPG-13 are active production devices from Diodes Incorporated with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The AP2191MPG-13 currently has higher inventory (7420 units) compared to AP2191AMP-13 (840 units), making it suitable for high-volume production requirements. Both parts maintain identical regulatory compliance status (REACH Unaffected, EAR99 classification) and are suitable for direct substitution in USB switching applications without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can AP2191MPG-13 be used as a direct replacement for AP2191AMP-13?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, package configuration, and fault protection features. No circuit modifications are required for substitution.
