Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP2805AMM-G1 is determined by the following critical parameters:

• Switch Type & Configuration: USB Switch with High Side, N-Channel, 1:1 output ratio
• Output Current Capability: Minimum 500mA required; higher ratings are acceptable
• Load Voltage Range: Must support 2.7V ~ 5.5V operation; narrower ranges are acceptable if they encompass the required operating window
• Fault Protection Features: Must include Current Limiting (Fixed), Over Temperature, Reverse Current, and UVLO protection
• Package Compatibility: 8-TSSOP or 8-MSOP footprint with 0.118" (3.00mm) width
• Operating Temperature Range: Must support -40°C ~ 85°C (TA)
• Compliance: ROHS3 compliance required

The BD82028FVJ-GE2 qualifies as a direct substitute based on matching all critical functional and electrical parameters, with enhanced current capability (1A vs. 500mA) and compatible packaging.

Parameter Comparison

Engineering Selection Recommendations

The BD82028FVJ-GE2 is the qualified substitute for the obsolete AP2805AMM-G1 based on the following engineering criteria:

Functional Equivalence: Both parts implement identical USB switch topology with High Side N-Channel 1:1 configuration and matching fault protection architecture (Current Limiting, Over Temperature, Reverse Current, UVLO).

Compliance & Certification: Both parts maintain ROHS3 compliance and identical regulatory status (REACH Unaffected, EAR99 classification, HTSUS 8542.39.0001).

Supply Chain Status: The BD82028FVJ-GE2 is Active with 230,200 units in stock, providing reliable long-term availability compared to the Obsolete AP2805AMM-G1 status.

Electrical Performance: The BD82028FVJ-GE2 provides enhanced current capability (1A vs. 500mA) and maintains compatible thermal operating range (-40°C ~ 85°C). The narrower load voltage range (4.5V ~ 5.5V vs. 2.7V ~ 5.5V) is acceptable for applications operating within the 4.5V ~ 5.5V window. The 72mOhm on-resistance (vs. 60mOhm) represents a 20% increase in conduction loss, which is within acceptable tolerance for most USB switching applications.

Package Compatibility: Identical 8-TSSOP/8-MSOP footprint with 0.118" (3.00mm) width enables direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the BD82028FVJ-GE2 directly replace the AP2805AMM-G1 on existing PCBs?

A: Yes. Both parts share identical 8-TSSOP/8-MSOP footprint and pin configuration. No PCB layout modifications are required. Verify that your application operates within the BD82028FVJ-GE2 load voltage range of 4.5V ~ 5.5V.

Q: What is the impact of the higher on-resistance (72mOhm vs. 60mOhm) in the BD82028FVJ-GE2?

A: The 20% increase in on-resistance results in proportionally higher conduction losses. For a 500mA load, this represents an additional 5mW of power dissipation. Thermal analysis should confirm that the package can dissipate this additional heat within your application's thermal environment.

Q: The BD82028FVJ-GE2 specifies 4.5V ~ 5.5V load voltage, but the AP2805AMM-G1 supports 2.7V ~ 5.5V. Can I use the substitute in lower voltage applications?

A: No. The BD82028FVJ-GE2 is not rated for operation below 4.5V. If your application requires operation below 4.5V, the substitute is not suitable. Consult alternative parts with extended low-voltage specifications.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution is determined by: (1) matching switch type and output configuration (USB Switch, High Side N-Channel 1:1), (2) output current capability meeting or exceeding 500mA, (3) load voltage range encompassing the application requirements, (4) identical fault protection features, (5) compatible package footprint, and (6) matching operating temperature range and compliance certifications.

Q: Is the higher current rating (1A vs. 500mA) of the BD82028FVJ-GE2 a concern?

A: No. Higher current capability does not create compatibility issues. The part will operate correctly at 500mA loads. The enhanced rating provides design margin and supports potential future applications with higher current requirements.

Q: Are there any differences in the control interface between these parts?

A: No. Both parts implement identical On/Off interface with Non-Inverting input type and matching Status Flag output. Control logic and signal timing are compatible.
