Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7341D-30FS4-7 are categorized based on the following substitution criteria:

Parametric Equivalents maintain identical electrical specifications across output voltage (3V fixed), output current capability (300mA), dropout voltage performance (0.65V @ 300mA), quiescent current (50 µA), PSRR (75dB @ 1kHz), control features (Enable), protection features (Over Current), operating temperature range (-40°C ~ 85°C), and package type (4-XDFN Exposed Pad). These parts are direct functional replacements with no design modifications required.

Manufacturer Recommended Alternatives provide equivalent output voltage and current specifications but may differ in dropout voltage, quiescent current, PSRR, package dimensions, or additional protection features. These parts are suitable when the application can tolerate performance variations or when enhanced features are beneficial.

Parameter Comparison

Engineering Selection Recommendations

AP7341-30FS4-7 (Diodes Incorporated): Parametric equivalent with identical electrical and mechanical specifications. Direct replacement with no design modifications. ROHS3 compliant, Active status, MSL 1 rating.

AP7343D-30FS4-7B (Diodes Incorporated): Parametric equivalent with improved dropout voltage performance (0.29V @ 300mA versus 0.65V). Maintains identical output voltage, current, package, and operating temperature range. Slightly elevated quiescent current (60 µA versus 50 µA). ROHS3 compliant, Active status, MSL 1 rating. Suitable for applications requiring lower power dissipation in dropout conditions.

BU30TD2WNVX-TL (Rohm Semiconductor): Manufacturer recommended alternative with reduced output current capability (200mA versus 300mA) and different package type (4-UDFN versus 4-XDFN). Enhanced protection features include Over Temperature protection. Maximum input voltage increased to 6V. ROHS3 compliant, Active status, MSL 1 rating. Suitable only for applications with output current requirements ≤200mA.

NCP160AMX300TBG (onsemi): Manufacturer recommended alternative with reduced output current capability (250mA versus 300mA) but superior dropout voltage performance (0.155V @ 250mA) and lower quiescent current (23 µA). Extended operating temperature range (-40°C ~ 125°C). Enhanced protection features include Over Temperature and Soft Start. ROHS3 compliant, Active status, MSL 1 rating. Suitable for applications with output current requirements ≤250mA and extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can AP7341-30FS4-7 be used as a direct replacement for AP7341D-30FS4-7?

A: Yes. AP7341-30FS4-7 is a parametric equivalent with identical electrical specifications, output voltage (3V), output current (300mA), dropout voltage (0.65V @ 300mA), quiescent current (50 µA), PSRR (75dB @ 1kHz), operating temperature range (-40°C ~ 85°C), and package type (4-XDFN Exposed Pad). No design modifications are required.

Q: What is the key difference between AP7343D-30FS4-7B and AP7341D-30FS4-7?

A: The primary difference is dropout voltage performance. AP7343D-30FS4-7B provides 0.29V dropout at 300mA compared to 0.65V for AP7341D-30FS4-7. Both maintain identical 3V output, 300mA current, and 4-XDFN package. Quiescent current is slightly higher (60 µA versus 50 µA). Selection depends on whether lower dropout voltage is required for the application.

Q: Can BU30TD2WNVX-TL replace AP7341D-30FS4-7 in all applications?

A: No. BU30TD2WNVX-TL has reduced output current capability (200mA versus 300mA) and uses a different package type (4-UDFN versus 4-XDFN). It is suitable only for applications requiring output current ≤200mA. PCB layout modifications may be required due to package differences.

Q: Is NCP160AMX300TBG compatible with the AP7341D-30FS4-7 package footprint?

A: Yes. NCP160AMX300TBG uses the same 4-XDFN Exposed Pad package type, allowing direct PCB footprint compatibility. However, output current is reduced to 250mA versus 300mA. Applications requiring full 300mA output cannot use this substitute.

Q: What are the compliance and regulatory considerations for these substitute parts?

A: All listed substitute parts are ROHS3 compliant, carry Active product status, and have MSL 1 (Unlimited) moisture sensitivity ratings. All are REACH Unaffected and classified under ECCN EAR99. No additional compliance modifications are required when substituting between these parts.

Q: Which substitute part offers the best performance improvement over AP7341D-30FS4-7?

A: NCP160AMX300TBG provides the most significant performance improvements: dropout voltage of 0.155V @ 250mA (versus 0.65V), lower quiescent current (23 µA versus 50 µA), higher PSRR (91dB ~ 48dB across frequency range), extended operating temperature range (-40°C ~ 125°C), and additional Soft Start protection. Trade-off is reduced output current (250mA versus 300mA).
