Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7366-15SN-7 are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Fixed output voltage of 1.5V
• Output current rating of 600mA
• Maximum input voltage of 6V
• Quiescent current of 80 µA
• PSRR specification of 75dB ~ 55dB (1kHz ~ 10kHz)
• Operating temperature range of -40°C ~ 85°C
• Identical protection features: Over Current, Over Temperature, Short Circuit
• Enable control feature

Mechanical Compatibility Criteria:

• Surface mount mounting type
• 6-pin package configuration with exposed pad
• ROHS3 compliance
• MSL rating of 1 (Unlimited)

Two substitute parts meet these criteria with variations in packaging format and dropout voltage performance:

1. AP7366EA-15SN-7 – MFR Recommended substitute with identical 6-UDFN package, improved dropout voltage specification (0.45V @ 600mA vs. 0.7V @ 600mA), and active product status.

2. AP7366EA-15W5-7 – Parametric equivalent with alternative SOT-25 package format, maintaining 0.7V dropout voltage specification, and active product status.

Parameter Comparison

Engineering Selection Recommendations

AP7366EA-15SN-7 is the primary recommended substitute for direct replacement of the AP7366-15SN-7. This part maintains identical package geometry (6-UDFN Exposed Pad, U-DFN2020-6), identical electrical specifications, and provides improved dropout voltage performance (0.45V @ 600mA versus 0.7V @ 600mA). The AP7366EA-15SN-7 carries active product status from Diodes Incorporated, ensuring long-term availability and supply chain continuity. All compliance certifications including ROHS3, REACH Unaffected, and MSL 1 rating are maintained.

AP7366EA-15W5-7 serves as a parametric equivalent when package format flexibility exists in the design. This substitute uses an alternative SOT-25 package (SC-74A, SOT-753) instead of the 6-UDFN format, maintaining all electrical specifications including the 0.7V dropout voltage characteristic. Selection of this part requires PCB layout modification to accommodate the different package footprint. The AP7366EA-15W5-7 also carries active product status and identical compliance certifications.

Both substitute parts are manufactured by Diodes Incorporated and provide equivalent functional performance within the specified electrical and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can AP7366EA-15SN-7 be used as a direct replacement for AP7366-15SN-7?

A: Yes. The AP7366EA-15SN-7 is a direct replacement with identical package format (6-UDFN Exposed Pad), identical electrical specifications, and improved dropout voltage performance. No PCB layout modifications are required.

Q: What is the difference between AP7366EA-15SN-7 and AP7366EA-15W5-7?

A: The primary difference is package format. AP7366EA-15SN-7 uses 6-UDFN Exposed Pad (U-DFN2020-6), while AP7366EA-15W5-7 uses SOT-25 (SC-74A, SOT-753). Both maintain identical electrical output specifications (1.5V, 600mA). The dropout voltage specification differs: AP7366EA-15SN-7 provides 0.45V @ 600mA, while AP7366EA-15W5-7 provides 0.7V @ 600mA.

Q: Why is the AP7366-15SN-7 marked as obsolete?

A: The AP7366-15SN-7 is classified as obsolete by Diodes Incorporated. The active equivalent parts AP7366EA-15SN-7 and AP7366EA-15W5-7 provide continued access to this voltage regulator functionality with improved specifications and guaranteed long-term availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both AP7366EA-15SN-7 and AP7366EA-15W5-7 are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status, matching the compliance profile of the original AP7366-15SN-7.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: fixed output voltage of 1.5V, output current of 600mA, maximum input voltage of 6V, quiescent current of 80 µA, PSRR specification of 75dB ~ 55dB (1kHz ~ 10kHz), operating temperature range of -40°C ~ 85°C, and identical protection features (Over Current, Over Temperature, Short Circuit).

Q: Can AP7366EA-15W5-7 be used if PCB layout space is limited?

A: The SOT-25 package used by AP7366EA-15W5-7 has different footprint dimensions than the 6-UDFN package. PCB layout modification is required. If space constraints exist, verify that the SOT-25 footprint fits within available board area before selecting this substitute.
