Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP22816BKBWT-7 are identified based on strict parametric equivalence within the AP22816 product family. All substitute candidates share identical electrical specifications across the following critical parameters:

• Switch Type: USB Switch
• Output Configuration: High Side
• Output Type: N/P-Channel
• Current Rating: 1A maximum output
• Load Voltage Range: 2.7V ~ 5.5V
• On-Resistance: 75mOhm typical
• Package: SOT-23-5 Thin (TSOT-23-5)
• Mounting: Surface Mount
• Operating Temperature: -40°C ~ 85°C
• Automotive Grade with AEC-Q100 qualification
• RoHS3 compliance and MSL Level 1

Substitution is valid when the replacement part maintains these core electrical and mechanical parameters. Differences in secondary features (such as Status Flag availability) do not affect functional interchangeability in standard USB power switching applications. All substitute parts are manufactured by Diodes Incorporated and carry Active product status.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AP22816BKBWT-7, AP22816BKAWT-7, and AP22816BKEWT-7—are functionally equivalent for USB power switching applications. Selection between these parts is based on the following engineering criteria:

Primary Selection Criteria:

1. Inventory Availability: AP22816BKAWT-7 (4,170 pcs), AP22816BKEWT-7 (3,679 pcs), and AP22816BKBWT-7 (2,264 pcs) are all available in stock. Choose based on supply chain requirements and lead time constraints.

2. Feature Requirements: AP22816BKAWT-7 and AP22816BKEWT-7 include Status Flag functionality in addition to Load Discharge. AP22816BKBWT-7 provides Load Discharge only. Select AP22816BKAWT-7 or AP22816BKEWT-7 if status monitoring is required in the application circuit.

3. Compliance and Qualification: All three parts maintain identical compliance profiles: Automotive Grade, AEC-Q100 qualification, ROHS3 compliance, MSL Level 1, and REACH Unaffected status. No compliance-based differentiation exists.

4. Electrical Performance: Identical electrical specifications across all three parts ensure direct pin-for-pin and functional compatibility. No performance trade-offs exist between substitutes.

Substitution Path: Any of the three parts can replace the others without circuit redesign, provided the application does not require Status Flag output. If Status Flag functionality is needed, use AP22816BKAWT-7 or AP22816BKEWT-7.

Frequently Asked Questions (FAQ)

Q: Can AP22816BKAWT-7 or AP22816BKEWT-7 be used as direct replacements for AP22816BKBWT-7?

A: Yes. All three parts share identical electrical specifications, package geometry (SOT-23-5 Thin, TSOT-23-5), and mounting requirements. Direct substitution is valid at the PCB level without circuit modification.

Q: What is the difference between AP22816BKBWT-7 and AP22816BKAWT-7?

A: The primary difference is the inclusion of Status Flag functionality in AP22816BKAWT-7. Both parts provide Load Discharge protection and identical current/voltage ratings (1A, 2.7V–5.5V). The Status Flag allows the application circuit to monitor switch state. Electrical performance and thermal characteristics are identical.

Q: Are AP22816BKEWT-7 and AP22816BKAWT-7 interchangeable?

A: Yes. Both parts include Status Flag functionality and Load Discharge protection. Electrical specifications, package, and operating temperature ranges are identical. Selection between these two is based solely on inventory availability.

Q: Does the Status Flag feature affect circuit compatibility?

A: No. The Status Flag is an additional output feature. If the application circuit does not use this output, AP22816BKAWT-7 and AP22816BKEWT-7 function identically to AP22816BKBWT-7. If the application requires status monitoring, the Status Flag output must be connected to the monitoring circuit.

Q: Are all three parts qualified for automotive applications?

A: Yes. All three parts carry Automotive Grade classification and AEC-Q100 qualification. They are suitable for automotive and industrial applications requiring automotive-level reliability and environmental performance.

Q: What is the package compatibility between these parts?

A: All three parts use the SOT-23-5 Thin package (TSOT-23-5) in Tape & Reel (TR) format. PCB footprints, solder pad layouts, and component placement are identical. No PCB redesign is required for substitution.

Q: Do these parts have different moisture sensitivity requirements?

A: No. All three parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control. Storage and handling requirements are identical.

Q: Can I substitute based on inventory alone?

A: Yes, if the application does not require Status Flag functionality. If Status Flag monitoring is required, select AP22816BKAWT-7 or AP22816BKEWT-7. Otherwise, choose based on availability and supply chain timing.

Q: Are there any thermal or performance differences between these parts?

A: No. All three parts have identical on-resistance (75mOhm typical), operating temperature range (-40°C to 85°C), and fault protection mechanisms. Thermal performance and electrical characteristics are equivalent.
