Key Parameters

Substitute Part Grouping Explanation

Substitution for the AP7340-22FS4-7 is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 2.2V fixed
• Output current capability: 150mA
• Input voltage maximum rating: 5.25V
• Dropout voltage performance: 0.36V @ 150mA
• Package configuration: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Mounting technology: Surface Mount
• Operating temperature range: -40°C to 85°C
• Control and protection features: Enable control with Over Current protection
• Compliance certifications: ROHS3 Compliant, MSL 1

The AP7340D-22FS4-7 meets all these criteria as a parametric equivalent from the same manufacturer and base product series (AP7340).

Parameter Comparison

Engineering Selection Recommendations

Both the AP7340-22FS4-7 and AP7340D-22FS4-7 are active production parts from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Supply chain sourcing preferences
• Cost considerations at procurement volume
• Packaging and tape reel specifications for automated assembly

Both parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture sensitivity concerns for both variants.

Frequently Asked Questions (FAQ)

Q: Can AP7340D-22FS4-7 be used as a direct replacement for AP7340-22FS4-7?

A: Yes. Both parts are parametric equivalents with identical electrical performance, output specifications, and package configuration. Direct substitution is supported without circuit modification.
