Substitute Part Grouping Explanation

Substitute parts for the AP22802AW5-7 are identified based on electrical and mechanical compatibility within the following critical parameters:

• Output Configuration: High-side P-Channel switch with 1:1 input-to-output ratio
• Current Rating: 2A maximum output current
• Load Voltage Range: 2.7V to 5.5V operation
• On-Resistance: 50mOhm typical
• Package Type: SOT-25 (SC-74A, SOT-753)
• Fault Protection: Current limiting, over-temperature, and UVLO protection
• Interface: On/Off control

Two substitute parts meet these electrical and mechanical criteria: AP22802BW5-7 and AP22811AW5-7. Both maintain identical output specifications, load voltage ratings, current capacity, and thermal characteristics required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

AP22802BW5-7: This part is a parametric equivalent to AP22802AW5-7, sharing identical electrical specifications and non-inverting input logic. Both parts carry "Not For New Designs" status. Selection between these two is determined by packaging availability and inventory requirements, as electrical performance and functional behavior are equivalent.

AP22811AW5-7: This part provides functional substitution with one key difference: inverting input logic versus the non-inverting configuration of AP22802AW5-7. The AP22811AW5-7 carries "Active" product status and includes additional reverse current fault protection. This part is suitable for applications where input signal inversion is acceptable or desired, and where active product support is required. The additional reverse current protection provides enhanced fault coverage compared to the main part.

For applications requiring exact non-inverting input behavior without modification, AP22802BW5-7 is the direct equivalent. For applications that can accommodate or benefit from inverting input logic, AP22811AW5-7 offers the advantage of active product status and extended fault protection.

Frequently Asked Questions (FAQ)

Q: Can AP22802BW5-7 be used as a direct drop-in replacement for AP22802AW5-7?

A: Yes. AP22802BW5-7 is electrically and mechanically identical to AP22802AW5-7. Both feature non-inverting input logic, identical current ratings (2A), on-resistance (50mOhm), load voltage range (2.7V–5.5V), and SOT-25 packaging. No circuit modifications are required.

Q: What is the primary difference between AP22811AW5-7 and AP22802AW5-7?

A: The AP22811AW5-7 features inverting input logic, whereas AP22802AW5-7 uses non-inverting logic. Both maintain identical output current (2A), on-resistance (50mOhm), and load voltage specifications. The AP22811AW5-7 also includes reverse current fault protection and carries active product status.

Q: Can AP22811AW5-7 replace AP22802AW5-7 without circuit changes?

A: No. The inverting input logic of AP22811AW5-7 requires circuit modification. The control signal polarity must be inverted in the application schematic. If input signal inversion is not feasible, AP22802BW5-7 is the appropriate substitute.

Q: Are all three parts available in the same package?

A: Yes. AP22802AW5-7, AP22802BW5-7, and AP22811AW5-7 are all supplied in SOT-25 packaging (SC-74A, SOT-753) with surface mount mounting type. PCB layout compatibility is maintained across all three parts.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates that AP22802AW5-7 and AP22802BW5-7 are mature products no longer recommended for new circuit designs. However, both remain available for existing production and maintenance applications. AP22811AW5-7 carries "Active" status, indicating ongoing manufacturer support and suitability for new designs.

Q: Do all three parts meet the same compliance standards?

A: Yes. AP22802AW5-7, AP22802BW5-7, and AP22811AW5-7 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All three carry identical REACH and ECCN classifications.
