AP7341-22FS4-7 Equivalent & Substitute Parts

Part Overview

The AP7341-22FS4-7 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a fixed 2.2V output at 300mA with a maximum dropout voltage of 0.65V, designed for surface mount applications in the 4-XDFN Exposed Pad package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative part numbers are necessary when addressing supply chain constraints, inventory availability, or specific packaging requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP7341-22FS4-7 is determined by strict equivalence across the following critical parameters:

• Output voltage configuration: Fixed positive 2.2V output
• Output current capability: 300mA
• Maximum input voltage: 5.25V
• Dropout voltage specification: 0.65V @ 300mA
• Package and pinout: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Mounting technology: Surface Mount
• Control and protection features: Enable control with Over Current protection
• Operating temperature range: -40°C ~ 85°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute part AP7341D-22FS4-7 meets all these criteria and is therefore a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both AP7341-22FS4-7 and AP7341D-22FS4-7 are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The AP7341D-22FS4-7 variant maintains significantly higher stock levels (33,180 units versus 784 units), making it the preferred choice for high-volume production or extended lead-time mitigation. Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for industrial and consumer applications. The identical package footprint (X2-DFN1010-4) and pinout configuration enable direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can AP7341D-22FS4-7 be used as a direct replacement for AP7341-22FS4-7?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current rating, dropout voltage, and package configuration. No circuit design changes are required.

Q: Are there any differences in the package or pinout between these parts?

A: No. Both parts use the identical 4-XDFN Exposed Pad package (X2-DFN1010-4) with the same pinout and footprint. PCB layout remains unchanged.

Q: What determines substitution eligibility for this linear regulator?

A: Substitution is valid when the alternative part maintains the same fixed output voltage (2.2V), output current (300mA), maximum input voltage (5.25V), dropout voltage (0.65V @ 300mA), package type, and operating temperature range (-40°C ~ 85°C).

Q: Do both parts meet the same compliance standards?

A: Yes. Both AP7341-22FS4-7 and AP7341D-22FS4-7 are ROHS3 Compliant and REACH Unaffected, with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Selection should prioritize inventory availability and supply chain stability. The AP7341D-22FS4-7 offers significantly higher stock levels and is recommended for production designs requiring supply assurance.
