Substitute Part Grouping Explanation

Substitution of the AP7366-36SN-7 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Output configuration (Positive)
• Output type (Fixed)
• Fixed output voltage (3.6V)
• Maximum output current (600mA)
• Input voltage rating (6V maximum)
• Quiescent current (80 µA)
• Operating temperature range (-40°C ~ 85°C)

Mechanical Equivalence Criteria:

• Package type (6-UDFN Exposed Pad)
• Surface mount mounting type
• Pin count and pinout compatibility

Compliance Equivalence Criteria:

• RoHS3 compliance
• MSL rating (1 - Unlimited)

The AP7366EA-36SN-7 meets all electrical, mechanical, and compliance requirements for direct substitution. The primary distinction is product status: the AP7366EA-36SN-7 is active production, whereas the AP7366-36SN-7 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The AP7366EA-36SN-7 is the direct substitute for the obsolete AP7366-36SN-7. Both devices are manufactured by Diodes Incorporated and share identical electrical specifications, output voltage, current ratings, and thermal operating range.

Selection Basis:

The AP7366EA-36SN-7 is recommended for new designs and production continuity because it maintains active product status with Diodes Incorporated. This ensures ongoing availability, technical support, and compliance with current manufacturing standards. Both parts carry ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), confirming suitability for standard surface mount assembly processes.

The substitute part is supplied in Tape & Reel (TR) packaging format, which is standard for high-volume production environments. The identical 6-UDFN Exposed Pad package ensures direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the AP7366EA-36SN-7 be used as a direct replacement for the AP7366-36SN-7?

A: Yes. The AP7366EA-36SN-7 is electrically and mechanically equivalent to the AP7366-36SN-7. Both devices feature identical output voltage (3.6V fixed), output current (600mA), input voltage rating (6V), quiescent current (80 µA), and package type (6-UDFN Exposed Pad). No circuit modifications or PCB redesign is required.

Q: What is the primary difference between these two part numbers?

A: The AP7366-36SN-7 is obsolete, while the AP7366EA-36SN-7 is in active production. The substitute part is available in Tape & Reel packaging, which is standard for manufacturing operations.

Q: Are the dropout voltage specifications identical?

A: The dropout voltage specifications differ. The AP7366-36SN-7 specifies 0.16V @ 300mA, while the AP7366EA-36SN-7 specifies 210mV @ 600mA. Both values are within acceptable operating parameters for 3.6V fixed output applications. Circuit designers should verify dropout performance against specific load conditions in their application.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the AP7366-36SN-7 and AP7366EA-36SN-7 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, confirming compatibility with standard surface mount assembly and storage protocols.

Q: Is the pinout identical between these parts?

A: Yes. Both parts use the 6-UDFN Exposed Pad package with identical pinout. Direct PCB footprint compatibility is confirmed.

Q: What control features are available on each part?

A: The AP7366-36SN-7 includes Current Limit and Enable control features. The AP7366EA-36SN-7 includes Enable control. Both parts provide Over Current, Over Temperature, and Short Circuit protection.
