Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP2311ASN-7 is determined by strict equivalence across the following critical parameters:

• Switch topology: P-Channel, high-side configuration, 1:1 ratio
• Electrical performance: 2A maximum output current, 70mOhm typical on-resistance
• Voltage rating: 2.7V to 5.5V load voltage range
• Package specification: 6-UDFN Exposed Pad surface mount
• Protection features: Current limiting, over-temperature, reverse current, and UVLO
• Compliance: ROHS3 compliance and active product status

The AP2511ASN-7 meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the AP2311ASN-7 and AP2511ASN-7 are active products from Diodes Incorporated with identical electrical specifications, package configurations, and compliance certifications. Selection between these parts is based on inventory availability and supply chain considerations. The AP2511ASN-7 currently has 779 units in stock compared to 609 units for the AP2311ASN-7. Both parts maintain ROHS3 compliance and REACH unaffected status, making either suitable for applications requiring regulatory compliance. The identical MSL rating of 1 (Unlimited) indicates both parts have the same moisture handling requirements during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can the AP2511ASN-7 be used as a direct replacement for the AP2311ASN-7?

A: Yes. The AP2511ASN-7 is a parametric equivalent with identical electrical specifications, package type, and protection features. No circuit modifications are required for substitution.

Q: Are there any differences in the 6-UDFN package between these parts?

A: No. Both parts use the identical 6-UDFN Exposed Pad package with the same pinout and mechanical dimensions. PCB layout and footprint remain unchanged.

Q: Do both parts have the same fault protection capabilities?

A: Yes. Both the AP2311ASN-7 and AP2511ASN-7 include current limiting (fixed), over-temperature protection, reverse current blocking, and UVLO (Under-Voltage Lock-Out) functionality.

Q: What is the significance of the MSL rating for these parts?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating they have unlimited shelf life and do not require special moisture control measures during storage or handling.

Q: Are there any compliance differences between these substitutes?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for environmental and hazardous substance restrictions.
