AP7387-50FDC-7 Equivalent & Substitute Parts

Part Overview

The AP7387-50FDC-7 is a Linear Voltage Regulator IC manufactured by Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a positive fixed 5V output at 150mA with low quiescent current of 4 µA, housed in a 6-UDFN Exposed Pad surface mount package. The part is currently in active production status and carries automotive-grade qualification (AEC-Q100), making it suitable for demanding automotive and industrial applications. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple packaging formats, and maintain design continuity when primary part availability is constrained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP7387-50FDC-7 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Output voltage: 5V fixed
• Output current capability: 150mA
• Maximum input voltage: 60V
• Dropout voltage: 1.35V @ 150mA
• Quiescent current: 4 µA
• Protection features: Over Current, Over Temperature, Short Circuit
• Control features: Current Limit

Mechanical & Packaging Parameters (Non-Negotiable):

• Package type: 6-UDFN Exposed Pad (U-DFN2020-6 Type C)
• Mounting type: Surface Mount

Compliance & Qualification Parameters (Non-Negotiable):

• Automotive Grade
• AEC-Q100 Qualification
• ROHS3 Compliant
• MSL 1 (Unlimited)

The only allowable variation between the main part and its substitute is the packaging format (Bulk versus Tape & Reel), which does not affect electrical or mechanical performance. All other parameters must remain identical for a part to qualify as a true substitute.

Parameter Comparison

Engineering Selection Recommendations

AP7387-50FDCR-7 is a direct parametric equivalent to AP7387-50FDC-7. Both parts are manufactured by Diodes Incorporated and maintain identical electrical, mechanical, and compliance specifications. The sole distinction is the packaging format: AP7387-50FDC-7 is supplied in Bulk packaging, while AP7387-50FDCR-7 is supplied in Tape & Reel (TR) format.

Selection Criteria:

• Use AP7387-50FDC-7 when bulk packaging is required for manual assembly, prototyping, or low-volume production runs.
• Use AP7387-50FDCR-7 when automated pick-and-place assembly is employed or when tape-and-reel format is mandated by manufacturing processes.

Both parts carry active product status, automotive-grade qualification (AEC-Q100), and full ROHS3 compliance. Either part is suitable for direct substitution in applications requiring a 5V, 150mA linear voltage regulator with automotive-grade reliability. No additional testing or qualification is required when switching between these two part numbers, as all functional and compliance parameters are identical.

Frequently Asked Questions (FAQ)

Q1: Can AP7387-50FDCR-7 be used as a direct replacement for AP7387-50FDC-7 in production?

A: Yes. AP7387-50FDCR-7 is a direct parametric equivalent. All electrical specifications, output voltage, current rating, dropout voltage, quiescent current, protection features, operating temperature range, and automotive qualifications are identical. The only difference is packaging format (Tape & Reel versus Bulk). No design changes or re-qualification are required.

Q2: What is the difference between Bulk and Tape & Reel packaging?

A: Bulk packaging supplies components loose in a container, suitable for manual assembly and prototyping. Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, optimized for automated pick-and-place assembly equipment. Both formats contain the same component with identical electrical performance.

Q3: Are both parts AEC-Q100 qualified?

A: Yes. Both AP7387-50FDC-7 and AP7387-50FDCR-7 carry AEC-Q100 automotive qualification and are rated for automotive-grade applications across the operating temperature range of -40°C to 125°C (TJ).

Q4: What are the key parameters that determine substitutability for this part?

A: Substitutability is determined by: output voltage (5V fixed), output current (150mA), maximum input voltage (60V), dropout voltage (1.35V @ 150mA), quiescent current (4 µA), package type (6-UDFN Exposed Pad), protection features (Over Current, Over Temperature, Short Circuit), and compliance certifications (AEC-Q100, ROHS3). Any deviation in these parameters disqualifies a part as a substitute.

Q5: Can I mix Bulk and Tape & Reel parts in the same production run?

A: Yes. Since both packaging formats contain electrically and mechanically identical components, they can be used interchangeably in the same circuit design and production run. However, assembly process compatibility should be verified with your manufacturing partner.

Q6: Is the 6-UDFN Exposed Pad package critical for substitution?

A: Yes. The package type is a non-negotiable substitution criterion. The 6-UDFN Exposed Pad (U-DFN2020-6 Type C) is the only allowable package for this part family. Any alternative package size or configuration disqualifies a part as a substitute.

Q7: What does MSL 1 (Unlimited) mean for handling and storage?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no special moisture control requirements during storage or handling. These parts do not require dry-pack storage or baking before assembly, simplifying logistics and inventory management.
