AP7341D-22FS4-7 Equivalent & Substitute Parts

Part Overview

The AP7341D-22FS4-7 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a fixed positive output of 2.2V at 300mA with a maximum dropout voltage of 0.65V. The part is actively produced and widely used in applications requiring low-voltage regulation with minimal quiescent current. Substitute parts are identified when electrical specifications, package compatibility, and compliance certifications remain identical across manufacturing variants.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7341D-22FS4-7 are identified based on strict electrical and mechanical parameter matching. The substitution criteria include:

• Fixed output voltage of 2.2V
• Output current rating of 300mA
• Maximum input voltage of 5.25V
• Dropout voltage specification of 0.65V @ 300mA
• Quiescent current of 50 µA
• PSRR of 75dB (1kHz)
• 4-XDFN Exposed Pad package configuration
• Surface mount mounting type
• Operating temperature range of -40°C ~ 85°C
• Active product status
• ROHS3 compliance

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Manufacturing variants within the same base product number (AP7341) that maintain identical electrical and package specifications are interchangeable.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status with ROHS3 compliance and REACH unaffected certification. Selection between AP7341D-22FS4-7 and AP7341-22FS4-7 is based on inventory availability and supply chain requirements, as both parts are electrically and mechanically identical. The "D" designation variant (AP7341D-22FS4-7) carries higher inventory levels (33,180 pcs) compared to the non-D variant (784 pcs), making it the preferred choice for applications with standard lead time requirements. Both variants are suitable for designs requiring 2.2V fixed output regulation at 300mA with surface mount integration in 4-XDFN packages.

Frequently Asked Questions (FAQ)

Q: Are AP7341D-22FS4-7 and AP7341-22FS4-7 fully interchangeable?

A: Yes. Both parts share identical electrical specifications, package configuration, and compliance certifications. The difference is a manufacturing variant designation only.

Q: What determines if a part can substitute for the AP7341D-22FS4-7?

A: A substitute part must match all key parameters: 2.2V fixed output, 300mA current rating, 5.25V maximum input, 0.65V dropout voltage, 50 µA quiescent current, 75dB PSRR, 4-XDFN Exposed Pad package, surface mount type, -40°C to 85°C operating range, and active product status with ROHS3 compliance.

Q: Can I use these parts in high-temperature applications?

A: The operating temperature range is specified as -40°C to 85°C. Applications requiring operation beyond this range require alternative components rated for extended temperature ranges.

Q: Are there any package compatibility considerations?

A: Both substitute parts use the 4-XDFN Exposed Pad package with surface mount configuration. PCB layout and thermal management design must accommodate the X2-DFN1010-4 supplier device package dimensions.

Q: What is the significance of the "D" designation in AP7341D-22FS4-7?

A: The "D" is a manufacturing variant identifier. It does not affect electrical performance or package compatibility. Selection is based on inventory availability and supply chain logistics.
