Engineering Selection Recommendations

Direct Equivalent (2.5A, Full Voltage Range): BD82024FVJ-E2 provides the closest functional match with 2.5A output capability and 2.8V ~ 5.5V voltage range. This part is Active status and ROHS3 compliant. The 90mOhm Rds On is higher than the original 60mOhm specification but remains within acceptable parameters for USB Switch applications. Packaging is 8-TSSOP-BJ, compatible with 8-MSOP footprint requirements.

Full Voltage Range Alternatives (2.7V ~ 5.5V): For applications requiring the complete 2.7V ~ 5.5V voltage range with reduced current requirements, BD82065FVJ-LBE2 (1.5A) and BD82004FVJ-MGE2 (2A) are Active status alternatives. BD82006FVJ-MGE2 offers 3A capability for applications requiring higher current headroom. All three maintain ROHS3 compliance and 8-TSSOP-BJ packaging.

Restricted Voltage Range Alternatives (4.5V ~ 5.5V): BD82034FVJ-GE2 (2.5A), BD82032FVJ-GE2 (2A), and BD82030FVJ-GE2 (1.5A) are suitable for applications operating exclusively within the 4.5V ~ 5.5V range. These parts are Active status with ROHS3 compliance. BD82034FVJ-GE2 matches the original 2.5A current rating.

Legacy Alternatives (Not For New Designs): BD82001FVJ-E2 is classified as Not For New Designs and should not be selected for new applications despite its 2.7V ~ 5.5V voltage range and 1A capability.

All recommended substitutes maintain the same 8-TSSOP or 8-MSOP package footprint, surface mount configuration, and operating temperature range (-40°C ~ 85°C TA) as the original part.

Frequently Asked Questions (FAQ)

Q: Can BD82024FVJ-E2 directly replace AP2820EMMTR-G1 in existing designs? A: Yes. BD82024FVJ-E2 provides functional equivalence with matching 2.5A output current, compatible voltage range (2.8V ~ 5.5V vs. 2.7V ~ 5.5V), and identical 8-TSSOP/8-MSOP package footprint. The higher Rds On (90mOhm vs. 60mOhm) results in increased power dissipation but does not affect switching functionality for USB Switch applications.

Q: What is the voltage range difference between BD82024FVJ-E2 and AP2820EMMTR-G1? A: AP2820EMMTR-G1 operates from 2.7V minimum load voltage, while BD82024FVJ-E2 operates from 2.8V minimum. This 0.1V difference is negligible for most applications. For designs requiring operation below 2.8V, select BD82065FVJ-LBE2, BD82004FVJ-MGE2, or BD82006FVJ-MGE2, which all support 2.7V minimum.

Q: Are there 2.5A alternatives with lower Rds On than BD82024FVJ-E2? A: BD82034FVJ-GE2 offers 2.5A with 72mOhm Rds On (lower than BD82024FVJ-E2's 90mOhm) but operates only within 4.5V ~ 5.5V voltage range. For full 2.7V ~ 5.5V range with 2.5A, BD82024FVJ-E2 is the available option.

Q: Can I use BD82032FVJ-GE2 (2A) instead of the 2.5A original part? A: BD82032FVJ-GE2 is suitable only if your application's maximum current requirement does not exceed 2A. This part operates within 4.5V ~ 5.5V range. Verify that your design does not require the full 2.5A capability or operation below 4.5V before substitution.

Q: What is the difference between BD82024FVJ-E2 and BD82034FVJ-GE2? A: Both support 2.5A output current. BD82024FVJ-E2 operates from 2.8V ~ 5.5V with 90mOhm Rds On. BD82034FVJ-GE2 operates from 4.5V ~ 5.5V with 72mOhm Rds On. Select BD82024FVJ-E2 for designs requiring operation below 4.5V; select BD82034FVJ-GE2 for designs operating exclusively at 4.5V and above where lower on-resistance is beneficial.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant, matching the original AP2820EMMTR-G1 compliance status.

Q: What packaging options are available for substitutes? A: All substitute parts use 8-TSSOP-BJ or 8-MSOP packaging with 0.118" (3.00mm) width, maintaining footprint compatibility with the original AP2820EMMTR-G1. Packaging variants (Cut Tape, Digi-Reel, Tape & Reel) do not affect electrical or mechanical compatibility.

Q: Why is BD82001FVJ-E2 listed if it is Not For New Designs? A: BD82001FVJ-E2 is included for reference in legacy system maintenance only. For new designs, select from Active status alternatives: BD82024FVJ-E2, BD82034FVJ-GE2, BD82032FVJ-GE2, BD82030FVJ-GE2, BD82028FVJ-GE2, BD82065FVJ-LBE2, BD82004FVJ-MGE2, or BD82006FVJ-MGE2.
