Substitute Part Grouping Explanation

Substitution eligibility for the AP2172ASG-13 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Switch Type: USB Switch
• Number of Outputs: 2
• Ratio - Input:Output: 1:2
• Voltage - Load: 2.7V ~ 5.5V
• Output Configuration: High Side
• Interface: On/Off
• Input Type: Non-Inverting
• Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Considerations:

• Output Type (P-Channel vs. N-Channel): Affects circuit topology and gate drive requirements
• Current - Output (Max): Minimum 1A required; higher ratings provide design margin
• Rds On (Typ): Lower values reduce power dissipation; 80mOhm to 90mOhm range acceptable
• Mounting Type: Surface Mount (consistent across all candidates)

Parameter Comparison

Engineering Selection Recommendations

AP2162ASG-13 (Diodes Incorporated): This part is a parametric equivalent to the AP2172ASG-13, differing only in the supplier device package designation (8-SO vs. 8-SOP). Both parts maintain identical electrical specifications, output type (P-Channel), current ratings (1A), and thermal characteristics. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are equivalent. This substitute is suitable for direct replacement in applications where the 8-SOIC physical package footprint is maintained. Significantly higher inventory availability (65,300 units) provides supply chain advantage.

BD2066FJ-LBE2 (Rohm Semiconductor): This part is a manufacturer-recommended substitute with functional equivalence in USB switching topology and output configuration. Key differences include output type (N-Channel vs. P-Channel), higher maximum output current (1.5A vs. 1A), and lower on-resistance (80mOhm vs. 90mOhm). The N-Channel topology requires circuit-level evaluation to confirm gate drive compatibility and signal polarity alignment with the original P-Channel design. All compliance certifications match the primary part. This substitute provides enhanced current capacity and reduced power dissipation characteristics.

Frequently Asked Questions (FAQ)

Q: Can AP2162ASG-13 be used as a direct drop-in replacement for AP2172ASG-13?

A: Yes. Both parts are manufactured by Diodes Incorporated with identical electrical specifications, output type, current ratings, voltage ranges, and thermal operating limits. The difference in supplier device package designation (8-SO vs. 8-SOP) does not affect functional compatibility when the 8-SOIC physical package footprint is used in the circuit design.

Q: What is the primary difference between AP2172ASG-13 and BD2066FJ-LBE2?

A: The primary difference is the output type: AP2172ASG-13 uses P-Channel output, while BD2066FJ-LBE2 uses N-Channel output. Additionally, BD2066FJ-LBE2 provides higher maximum output current (1.5A vs. 1A) and lower on-resistance (80mOhm vs. 90mOhm). Circuit-level evaluation is required to confirm gate drive signal compatibility when substituting between P-Channel and N-Channel topologies.

Q: Are all three parts physically compatible with the same PCB footprint?

A: All three parts use the 8-SOIC (0.154", 3.90mm Width) package case with surface mount mounting type. Physical PCB footprint compatibility is maintained across all three parts. However, internal pin configuration differences between P-Channel (AP2172ASG-13, AP2162ASG-13) and N-Channel (BD2066FJ-LBE2) designs require schematic-level verification.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts. Compliance certifications are equivalent across the primary part and all substitutes.

Q: Which substitute should be selected for maximum design margin?

A: BD2066FJ-LBE2 provides the highest maximum output current (1.5A) and lowest on-resistance (80mOhm), offering enhanced performance margin. However, the N-Channel topology requires circuit compatibility verification. AP2162ASG-13 provides direct electrical equivalence with the advantage of higher inventory availability (65,300 units).
