Substitute Part Grouping Explanation

Substitute parts for the AP7340D-30FS4-7 are grouped based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Output voltage fixed at 3V
• Output current capability of 150mA or greater
• Input voltage maximum of 5.25V or greater
• Surface Mount packaging in 4-pin DFN/UDFN/XDFN configurations
• Operating temperature range of -40°C to 85°C or wider
• ROHS3 compliance and Active product status

Substitute Categories:

Parametric Equivalent: AP7340-30FS4-7 (Diodes Incorporated) — Identical electrical specifications and package, alternative tape & reel configuration.

MFR Recommended Substitutes:

• BU30TD2WNVX-TL (Rohm Semiconductor) — Higher output current (200mA), compatible package, extended input voltage tolerance
• MCP1711T-30I/5X (Microchip Technology) — Matched output current (150mA), ultra-low quiescent current, alternative package format
• NCP161AMX300TBG (onsemi) — Higher output current (450mA), superior PSRR performance, extended temperature range to 125°C

Parameter Comparison

Engineering Selection Recommendations

AP7340-30FS4-7 (Diodes Incorporated): Direct parametric equivalent with identical electrical performance and package specification. Suitable for one-to-one replacement in existing designs. Both parts maintain Active product status and ROHS3 compliance.

BU30TD2WNVX-TL (Rohm Semiconductor): Recommended when higher output current capacity (200mA vs. 150mA) is required within the same 3V output specification. Extended input voltage tolerance (6V max) provides additional design margin. Package transition from 4-XDFN to 4-UDFN requires PCB layout verification. Active status and ROHS3 compliance maintained.

MCP1711T-30I/5X (Microchip Technology): Recommended for ultra-low power applications requiring minimal quiescent current (1.27µA vs. 50µA). Matched 150mA output current maintains load capability. Higher dropout voltage (0.67V) must be evaluated against input voltage headroom. Active status and ROHS3 compliance maintained.

NCP161AMX300TBG (onsemi): Recommended for applications requiring higher output current (450mA) or extended operating temperature range to 125°C. Superior PSRR performance (91dB at 100Hz) benefits noise-sensitive applications. Package remains 4-XDFN Exposed Pad. Enhanced protection features (Over Temperature, Soft Start) provide additional circuit robustness. Active status and ROHS3 compliance maintained.

Frequently Asked Questions (FAQ)

Q: Can AP7340-30FS4-7 replace AP7340D-30FS4-7 directly?

A: Yes. Both parts are parametric equivalents from Diodes Incorporated with identical electrical specifications, output voltage (3V), output current (150mA), package type (4-XDFN Exposed Pad), and operating temperature range (-40 to 85°C). The difference is tape & reel configuration only.

Q: What is the primary difference between BU30TD2WNVX-TL and the original part?

A: BU30TD2WNVX-TL provides 200mA output current versus 150mA, and accepts input voltage up to 6V versus 5.25V. Package changes from 4-XDFN to 4-UDFN, requiring PCB layout verification. Dropout voltage increases to 0.46V at 200mA.

Q: When should MCP1711T-30I/5X be selected?

A: Select MCP1711T-30I/5X when quiescent current minimization is critical for battery-powered or low-power standby applications. Quiescent current is 1.27µA compared to 50µA in the original part. Evaluate the higher dropout voltage (0.67V) against available input voltage headroom.

Q: Is NCP161AMX300TBG suitable for high-current applications?

A: Yes. NCP161AMX300TBG delivers 450mA output current, three times the original 150mA specification. It maintains the same 4-XDFN package footprint, enabling direct PCB layout compatibility. Extended temperature range to 125°C and enhanced protection features (Over Temperature, Soft Start) support demanding applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—AP7340-30FS4-7, BU30TD2WNVX-TL, MCP1711T-30I/5X, and NCP161AMX300TBG—are ROHS3 compliant with Active product status.

Q: What package considerations apply when switching between substitutes?

A: AP7340D-30FS4-7, AP7340-30FS4-7, and NCP161AMX300TBG use 4-XDFN Exposed Pad packages with identical footprints. BU30TD2WNVX-TL and MCP1711T-30I/5X use 4-UDFN Exposed Pad packages, which differ in pin configuration and require PCB layout modification. Verify pinout compatibility before substitution.

Q: Can output current be exceeded in any substitute part?

A: No. Each substitute part has a specified maximum output current rating. Exceeding this rating activates Over Current protection. For applications requiring current above 150mA, BU30TD2WNVX-TL (200mA) or NCP161AMX300TBG (450mA) are appropriate selections.
