Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7341-30FS4-7 are classified into two categories based on substitution criteria:

Parametric Equivalents maintain identical electrical specifications and package compatibility:

• Output voltage: 3V fixed
• Output current: 300mA
• Input voltage maximum: 5.25V
• Package: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Dropout voltage: 0.65V @ 300mA
• Operating temperature: -40°C ~ 85°C
• Control features: Enable
• Protection: Over Current

Manufacturer Recommended Alternatives provide functional equivalence with allowable parameter variations:

• Output voltage: 3V fixed
• Output current: 200mA to 250mA (reduced from 300mA)
• Input voltage maximum: 5.5V to 6V (higher than 5.25V)
• Package: 4-XDFN or 4-UDFN Exposed Pad (compatible footprints)
• Dropout voltage: Lower than 0.65V (improved performance)
• Operating temperature: -40°C ~ 85°C or extended to 125°C
• Control features: Enable
• Protection: Over Current, Over Temperature, Soft Start (enhanced)

Parameter Comparison

Engineering Selection Recommendations

AP7341D-30FS4-7 (Diodes Incorporated): Direct parametric equivalent with identical electrical specifications and package. All parameters match the AP7341-30FS4-7. Higher inventory availability (30,100 pcs) supports supply chain continuity. ROHS3 compliant and Active status. Recommended for direct replacement without design modification.

AP7343D-30FS4-7B (Diodes Incorporated): Parametric equivalent with improved dropout voltage performance (0.29V vs. 0.65V @ 300mA). Maintains 300mA output current and 3V fixed output. Identical package and operating temperature range. Highest inventory availability (100,400 pcs). ROHS3 compliant and Active status. Suitable for applications requiring lower power dissipation.

BU30TD2WNVX-TL (Rohm Semiconductor): Manufacturer recommended alternative with reduced output current (200mA vs. 300mA). Enhanced protection features include Over Temperature and Soft Start. Lower dropout voltage (0.46V @ 200mA). Compatible 4-UDFN package footprint. ROHS3 compliant and Active status. Applicable when output current requirement does not exceed 200mA.

Enhanced protection features include Over Temperature and Soft Start. Lower quiescent current (23 µA). Compatible 4-XDFN package. ROHS3 compliant and Active status. Suitable for applications requiring extended temperature operation and improved efficiency.

Frequently Asked Questions (FAQ)

Q: Can AP7341D-30FS4-7 replace AP7341-30FS4-7 without design changes?

A: Yes. AP7341D-30FS4-7 is a parametric equivalent with identical output voltage (3V), output current (300mA), dropout voltage (0.65V @ 300mA), package (4-XDFN Exposed Pad), and operating temperature range (-40°C ~ 85°C). No design modification is required.

Q: What is the difference between AP7343D-30FS4-7B and AP7341-30FS4-7?

A: Both deliver 300mA at 3V in the same 4-XDFN package. The primary difference is dropout voltage: AP7343D-30FS4-7B operates at 0.29V @ 300mA compared to 0.65V @ 300mA for AP7341-30FS4-7. This results in lower power dissipation and heat generation. Quiescent current is slightly higher (60 µA vs. 50 µA).

Q: Can BU30TD2WNVX-TL be used as a direct substitute?

A: BU30TD2WNVX-TL is a manufacturer recommended alternative, not a direct parametric equivalent. Output current is reduced to 200mA (vs. 300mA). The 4-UDFN package is footprint compatible with 4-XDFN. Use only when maximum output current requirement does not exceed 200mA.

Q: What are the advantages of NCP160AMX300TBG over AP7341-30FS4-7?

A: NCP160AMX300TBG provides superior dropout voltage (0.155V @ 250mA vs. 0.65V @ 300mA), lower quiescent current (23 µA vs. 50 µA), extended operating temperature to 125°C, and enhanced protection features (Over Temperature, Soft Start). Output current is 250mA. Use when efficiency and extended temperature operation are required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and Active status, meeting regulatory requirements equivalent to the AP7341-30FS4-7.

Q: What is the package compatibility between 4-XDFN and 4-UDFN?

A: Both 4-XDFN and 4-UDFN are 4-pin exposed pad packages with compatible footprints for surface mount applications. BU30TD2WNVX-TL uses 4-UDFN (SSON004X1010) and is footprint compatible with the 4-XDFN (X2-DFN1010-4) package of AP7341-30FS4-7.
