Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP2822GKATR-G1 is determined by strict equivalence across the following critical parameters:

• Switch Type: USB Switch
• Output Configuration: High Side
• Ratio - Input:Output: 1:1
• Current - Output (Max): 2A minimum
• Voltage - Load: 2.7V ~ 5.5V compatibility
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

The AP22818AKAWT-7 qualifies as a direct substitute based on matching all critical electrical parameters and compliance requirements. While the substitute features an N/P-Channel output type (versus N-Channel only) and improved Rds On specification (75mOhm versus 85mOhm), these represent functional enhancements rather than deviations. The substitute operates within identical voltage and current ranges, maintains the same 1:1 ratio configuration, and supports the same USB switching application profile.

Parameter Comparison

Engineering Selection Recommendations

The AP22818AKAWT-7 is the qualified substitute for the obsolete AP2822GKATR-G1. Selection is based on:

• Active product status ensuring ongoing availability and manufacturing support
• Full electrical parameter equivalence across voltage, current, and switching specifications
• ROHS3 compliance matching the original part
• Improved MSL rating (1 versus 3) providing superior moisture handling characteristics
• Enhanced Rds On performance (75mOhm versus 85mOhm) delivering lower on-state resistance
• Identical operating temperature range and mounting configuration

The substitute maintains functional compatibility with existing circuit designs while providing improved reliability characteristics and long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the AP22818AKAWT-7 directly replace the AP2822GKATR-G1 in existing designs?

A: Yes. Both parts operate at identical voltage ranges (2.7V ~ 5.5V), support 2A maximum output current, maintain 1:1 input-output ratio, and function as high-side USB switches. The substitute's improved Rds On specification (75mOhm) represents a performance enhancement with no negative impact on circuit operation.

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

A: The AP22818AKAWT-7 carries MSL 1 (Unlimited moisture exposure) versus MSL 3 (168 hours) for the original part. This indicates superior moisture resistance in the substitute, reducing risk during storage and handling in humid environments.

Q: Are there package compatibility considerations?

A: The AP2822GKATR-G1 uses SC-74A/SOT-753 packaging. The AP22818AKAWT-7 uses TSOT-25 packaging (SOT-23-5 Thin variant). Both are surface-mount packages with compatible pinout for USB switch applications. PCB layout verification is required to confirm physical fit.

Q: Does the N/P-Channel output type of the substitute affect compatibility?

A: The substitute's N/P-Channel capability is a superset of the original N-Channel specification. Designs utilizing N-Channel switching operate identically with the substitute. The additional P-Channel capability does not impact existing circuit functionality.

Q: What compliance certifications apply to both parts?

A: Both the AP2822GKATR-G1 and AP22818AKAWT-7 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
