Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7335A-50SN-7 must satisfy the following criteria based on allowed electrical and mechanical parameters:

Critical Compatibility Parameters:

• Package / Case: 6-UDFN Exposed Pad (identical footprint and pinout required)
• Voltage - Input (Max): 6V or greater
• Operating Temperature: -40°C ~ 85°C or wider range
• Mounting Type: Surface Mount
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Functional Parameters:

• Output Configuration: Positive
• Number of Regulators: 1
• Protection Features: Over Current, Over Temperature, Short Circuit
• Control Features: Enable

The AP7366EA-SN-7 qualifies as a substitute part because it maintains identical package specifications, input voltage rating, operating temperature range, and regulatory compliance. While the AP7366EA-SN-7 offers adjustable output voltage (0.8V to 5V) and higher current capacity (600mA), it can be configured to deliver fixed 5V output through external resistor networks, making it functionally compatible for applications currently using the AP7335A-50SN-7.

Parameter Comparison

Engineering Selection Recommendations

The AP7366EA-SN-7 is the designated manufacturer substitute for the AP7335A-50SN-7. Selection of this substitute part is supported by the following engineering factors:

Regulatory and Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental standards.

Package and Pinout Compatibility: Identical 6-UDFN Exposed Pad packaging ensures direct PCB footprint compatibility without layout modifications.

Electrical Operating Range: Both parts operate across the same temperature range (-40°C ~ 85°C) and accept identical maximum input voltage (6V), maintaining system thermal and voltage stress parameters.

Active Product Status: The AP7366EA-SN-7 maintains Active product status with confirmed inventory availability (3800 Pcs), providing long-term supply chain security compared to the Last Time Buy status of the AP7335A-50SN-7.

Enhanced Performance Characteristics: The substitute part provides higher current capacity (600mA versus 300mA) and improved PSRR performance, offering design margin for applications with variable load conditions.

Frequently Asked Questions (FAQ)

Q: Can the AP7366EA-SN-7 directly replace the AP7335A-50SN-7 without circuit modifications?

A: The AP7366EA-SN-7 shares identical package, pinout, and input voltage specifications. However, the AP7366EA-SN-7 is an adjustable output regulator requiring external resistor divider networks to set fixed 5V output, whereas the AP7335A-50SN-7 provides fixed 5V output without external components. Circuit modifications are necessary to configure the substitute part for fixed voltage operation.

Q: What are the key electrical differences between these parts?

A: The primary differences are output voltage configuration (fixed versus adjustable), current capacity (300mA versus 600mA), and dropout voltage characteristics (0.2V @ 300mA versus 0.85V @ 600mA). Both parts maintain identical quiescent current (80 µA) and operating temperature range.

Q: Are there any package or mounting considerations when switching to the AP7366EA-SN-7?

A: No. Both parts use identical 6-UDFN Exposed Pad surface mount packaging. PCB footprints, solder reflow profiles, and assembly processes remain unchanged.

Q: Why is the AP7366EA-SN-7 recommended despite higher dropout voltage?

A: The higher dropout voltage (0.85V @ 600mA) occurs at the substitute part's maximum rated current. For applications operating at or below 300mA, the dropout voltage differential is minimal. The substitute part's Active product status and higher current capacity provide superior long-term availability and design flexibility.

Q: What compliance certifications apply to both parts?

A: Both the AP7335A-50SN-7 and AP7366EA-SN-7 are ROHS3 compliant and REACH unaffected, meeting environmental and hazardous substance restrictions applicable to electronic components in regulated markets.
