Engineering Selection Recommendations

AP7366EA-10SN-7 (Primary Substitute)

The AP7366EA-10SN-7 is the direct parametric equivalent to the AP7366-10SN-7. Both devices share identical packaging (6-UDFN Exposed Pad, U-DFN2020-6), electrical specifications, and compliance certifications. The AP7366EA-10SN-7 is currently in active production status with higher inventory availability (4079 pcs vs. 946 pcs). The dropout voltage is improved at 0.85V @ 600mA compared to 1.2V @ 600mA on the main part, providing enhanced efficiency in applications with tight input-to-output voltage margins. This part is the recommended first choice for direct replacement.

AP7366EA-10W5-7 (Alternative Substitute)

The AP7366EA-10W5-7 maintains all critical electrical parameters but differs in package configuration, utilizing SOT-25 (SC-74A, SOT-753) instead of 6-UDFN. This part is suitable only for applications where PCB layout and pin assignment accommodate the SOT-25 footprint. The dropout voltage specification matches the main part at 1.2V @ 600mA. This device is in active production with substantial inventory (3845 pcs). Selection of this part requires PCB redesign or compatibility verification with existing SOT-25 footprints.

Both substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical functional specifications for output voltage, current capacity, protection features, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can AP7366EA-10SN-7 be used as a direct replacement for AP7366-10SN-7?

A: Yes. The AP7366EA-10SN-7 is a direct parametric equivalent with identical packaging (6-UDFN Exposed Pad), output voltage (1V fixed), output current (600mA), input voltage rating (6V max), protection features, and operating temperature range (-40°C ~ 85°C). No PCB modifications are required. The improved dropout voltage (0.85V vs. 1.2V @ 600mA) provides a performance advantage.

Q: What is the difference between AP7366EA-10SN-7 and AP7366EA-10W5-7?

A: Both parts are electrically equivalent with identical output specifications (1V, 600mA). The primary difference is packaging: AP7366EA-10SN-7 uses 6-UDFN Exposed Pad (U-DFN2020-6), while AP7366EA-10W5-7 uses SOT-25 (SC-74A, SOT-753). Selection depends on PCB footprint compatibility. The AP7366EA-10SN-7 maintains the original package type and is recommended for direct substitution.

Q: Why is the AP7366-10SN-7 listed as obsolete?

A: The AP7366-10SN-7 is obsolete, but equivalent active parts are available from the same manufacturer. The AP7366EA series represents the current production line for this regulator topology. Transitioning to active parts ensures long-term supply chain stability and access to manufacturing support.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All parts (AP7366-10SN-7, AP7366EA-10SN-7, and AP7366EA-10W5-7) are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Compliance certifications are identical across all three parts.

Q: What is the inventory status for each part?

A: AP7366-10SN-7 (main, obsolete): 946 pcs. AP7366EA-10SN-7 (active): 4079 pcs. AP7366EA-10W5-7 (active): 3845 pcs. The active substitutes offer significantly higher availability.

Q: Can AP7366EA-10W5-7 be used if my PCB is designed for 6-UDFN?

A: No. The AP7366EA-10W5-7 uses SOT-25 packaging, which has a different pin count and footprint than 6-UDFN. PCB redesign is required to accommodate this package type. For designs using 6-UDFN footprints, AP7366EA-10SN-7 is the appropriate substitute.
