Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP2501SN-7 is determined by strict alignment with the following critical parameters:

• Switch Type: USB Switch
• Output Type: P-Channel
• Output Configuration: High Side
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Voltage - Load Range: 2.7V ~ 5.5V
• Current - Output (Max): 2.5A
• Rds On (Typ): 70mOhm
• Package / Case: 6-UDFN Exposed Pad
• Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO
• Features: Load Discharge, Status Flag

A valid substitute must match all electrical specifications, thermal characteristics, protection features, and physical packaging requirements. The AP2501SN-7 itself represents the parametric equivalent within the available inventory.

Engineering Selection Recommendations

The AP2501SN-7 is classified as obsolete. For new designs or ongoing production requiring this functionality, component selection should prioritize parts with current product status while maintaining identical electrical and mechanical specifications.

Selection criteria based on provided data:

• Verify RoHS3 compliance for regulatory requirements in target markets
• Confirm MSL rating compatibility with assembly processes (MSL 1 indicates unlimited shelf life)
• Validate package handling and reflow compatibility with existing manufacturing equipment
• Ensure fault protection feature set (Current Limiting, Over Temperature, Reverse Current, UVLO) meets application safety requirements

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the AP2501SN-7?

A: A valid substitute must match all specified electrical parameters including P-Channel output type, high-side configuration, 2.5A maximum output current, 70mOhm typical on-resistance, and 2.7V to 5.5V load voltage range. The package must be 6-UDFN Exposed Pad, and all fault protection features (Current Limiting, Over Temperature, Reverse Current, UVLO) and load discharge/status flag capabilities must be present.

Q: Why is the AP2501SN-7 marked as obsolete?

A: Product status is provided in the component data. Obsolete classification indicates the part is no longer in active production. Existing inventory may remain available, but long-term availability cannot be guaranteed.

Q: Can I use a different package variant of the AP2501?

A: No. The 6-UDFN Exposed Pad package is a critical specification. Different package variants will not be mechanically or electrically compatible with existing PCB designs.

Q: What is the significance of the MSL 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling, simplifying inventory management and reducing component preparation time before assembly.

Q: Are there any compliance considerations for this part?

A: The AP2501SN-7 is ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for most markets. Verify compliance requirements for your specific application and target regions.
