Substitute Part Grouping Explanation

Substitution eligibility for the AP2101SG-13 is determined by strict equivalence across 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: 2.7V ~ 5.5V
• Current - Output (Max): 2A
• Rds On (Typ): 95mOhm
• Operating Temperature: -35°C ~ 85°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The AP2111SG-13 meets all substitution criteria as a parametric equivalent. Both devices share identical electrical specifications, thermal operating range, and physical packaging. Differences exist only in base product series designation and moisture sensitivity level classification.

Parameter Comparison

Engineering Selection Recommendations

Both AP2101SG-13 and AP2111SG-13 are active production devices manufactured by Diodes Incorporated with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following criteria:

AP2101SG-13 is appropriate for applications where immediate availability from existing inventory is prioritized and moisture sensitivity level 3 (168-hour floor life) meets storage and handling requirements.

AP2111SG-13 is appropriate for applications requiring extended shelf life and reduced moisture sensitivity risk, with moisture sensitivity level 1 providing unlimited floor life. This part also maintains higher inventory availability at 21,901 units.

Both devices satisfy identical electrical performance requirements for P-Channel high-side USB switching applications with 2A maximum output current and 95mOhm typical on-resistance. Thermal operating range, package geometry, and mounting configuration are fully equivalent.

Frequently Asked Questions (FAQ)

Q: Can AP2111SG-13 be used as a direct replacement for AP2101SG-13 in existing designs?

A: Yes. The AP2111SG-13 is a parametric equivalent with identical electrical specifications, thermal range, and physical packaging. No circuit modifications are required for substitution.

Q: What is the difference between these two parts?

A: The primary differences are moisture sensitivity level classification (AP2101SG-13 is MSL 3; AP2111SG-13 is MSL 1) and current inventory quantities. All electrical and mechanical parameters are identical.

Q: Does moisture sensitivity level affect circuit performance?

A: Moisture sensitivity level does not affect electrical performance. It specifies maximum floor life after package opening. MSL 1 (unlimited) provides greater flexibility in manufacturing and storage environments compared to MSL 3 (168 hours).

Q: Are both parts available in the same package?

A: Yes. Both AP2101SG-13 and AP2111SG-13 are supplied in 8-SOIC (0.154", 3.90mm Width) surface mount packaging with identical pinout and land pattern.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.
