Substitute Part Grouping Explanation

Substitution for the AP7343D-09W5-7 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 0.9V
• Output current capability of 300mA
• Maximum input voltage of 5.25V
• Voltage dropout specification of 0.8V @ 300mA
• Package configuration: SC-74A, SOT-753 (SOT-25)
• Surface Mount mounting type
• Operating temperature range: -40°C to 85°C
• Active product status
• RoHS3 compliance

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

The AP7343D-09W5-7 maintains higher inventory levels (53,280 pcs) compared to the AP7343-09W5-7 (3,655 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are AP7343D-09W5-7 and AP7343-09W5-7 pin-for-pin compatible?

A: Yes. Both parts use the SC-74A, SOT-753 package configuration with identical pinout and electrical characteristics.

Q: Can these parts be used interchangeably in production?

A: Yes. The parts are parametric equivalents with matching output voltage, current rating, dropout voltage, and operating temperature specifications. PCB layout and design do not require modification.

Q: What is the significance of the package designation SOT-25?

A: SOT-25 is the supplier device package designation for both parts, corresponding to the SC-74A, SOT-753 case outline. This is a standard 5-pin Surface Mount package.

Q: Are there any compliance differences between these substitutes?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and carry identical MSL Level 1 ratings.

Q: What determines substitution eligibility for this product category?

A: Substitution is determined by matching output voltage (0.9V fixed), output current (300mA), input voltage rating (5.25V max), dropout voltage (0.8V @ 300mA), package type (SOT-25), and operating temperature range (-40°C to 85°C).
