Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP7387-30FDC-7 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Output voltage configuration: Positive, Fixed at 3V
• Maximum output current: 150mA
• Maximum input voltage: 60V
• Maximum dropout voltage: 1.35V @ 150mA
• Quiescent current: 4 µA
• Control features: Current Limit
• Protection features: Over Current, Over Temperature, Short Circuit

Mechanical & Environmental Parameters:

• Package type: 6-UDFN Exposed Pad (U-DFN2020-6 Type C)
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 125°C (TJ)
• Automotive Grade qualification: AEC-Q100
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Only parts matching all specified parameters across these categories qualify as direct substitutes. Packaging differences, compliance variations, or electrical specification deviations disqualify alternative parts from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

The AP7387-30FDCR-7 qualifies as a direct parametric equivalent to the AP7387-30FDC-7. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications, package configurations, and automotive qualifications. The primary distinction between these parts is the packaging format designation (FDC versus FDCR), which reflects different supplier packaging and tape-and-reel configurations rather than functional or electrical differences.

Selection Criteria:

Both parts maintain Active product status and carry full AEC-Q100 automotive qualification with ROHS3 compliance. The AP7387-30FDCR-7 currently maintains higher inventory availability (4017 units versus 3516 units), which may provide supply chain advantages in high-volume procurement scenarios. Component selection between these equivalents should be based on packaging requirements, supplier logistics, and inventory availability rather than electrical performance considerations, as all specified parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can the AP7387-30FDCR-7 be used as a direct replacement for the AP7387-30FDC-7 in automotive applications?

A: Yes. Both parts are electrically and mechanically identical, carry identical AEC-Q100 automotive qualifications, and are manufactured by the same supplier. The parts differ only in packaging format designation and tape-and-reel configuration.

Q: What is the difference between the FDC and FDCR designations?

A: The FDC and FDCR designations indicate different supplier packaging and tape-and-reel formats. These are packaging variants of the same component and do not reflect functional or electrical differences. Both are 6-UDFN Exposed Pad surface mount packages.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: AEC-Q100 automotive qualification, ROHS3 compliance, and REACH Unaffected status. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: output voltage (3V fixed), output current (150mA), input voltage rating (60V maximum), dropout voltage (1.35V @ 150mA), quiescent current (4 µA), package type (6-UDFN Exposed Pad), operating temperature range (-40°C ~ 125°C), and automotive grade qualification (AEC-Q100).

Q: Can these parts be used in non-automotive applications?

A: Yes. While both parts carry automotive grade qualification, they are suitable for general industrial and commercial applications. The automotive qualification indicates enhanced reliability and quality standards that exceed standard commercial requirements.

Q: What is the significance of the 4 µA quiescent current specification?

A: The 4 µA quiescent current represents the standby current consumption when the regulator is operating but delivering minimal load current. This low value is critical for battery-powered and low-power applications where standby power consumption must be minimized.

Q: Are there inventory considerations when selecting between these equivalents?

A: Yes. The AP7387-30FDCR-7 currently maintains higher inventory (4017 units) compared to the AP7387-30FDC-7 (3516 units). For high-volume orders or time-sensitive procurement, the higher inventory availability of the FDCR variant may provide supply chain advantages.
