AP7315-26FS4-7B Equivalent & Substitute Parts

Part Overview

The AP7315-26FS4-7B is a linear voltage regulator IC from Diodes Incorporated designed for power management applications. This positive fixed output regulator delivers 150mA at 2.6V with a maximum dropout voltage of 0.32V, making it suitable for low-power supply circuits requiring stable voltage regulation. The device is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP7315-26FS4-7B is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 2.6V
• Output current rating of 150mA
• Maximum input voltage of 5.25V
• Dropout voltage specification of 0.32V @ 150mA
• Quiescent current of 60 µA
• PSRR of 75dB (1kHz)
• Package configuration: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Operating temperature range: -40°C to 85°C
• Over Current protection feature
• Active product status
• RoHS3 compliance

The AP7315D-26FS4-7B meets all substitution criteria as a parametric equivalent from the same manufacturer, differing only in the die variant designation (D suffix) while maintaining identical electrical specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both AP7315-26FS4-7B and AP7315D-26FS4-7B are active production devices with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. Both devices carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL 1 rating (unlimited moisture sensitivity) indicates these components require standard handling practices without special moisture control measures during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can AP7315D-26FS4-7B be used as a direct replacement for AP7315-26FS4-7B?

A: Yes. The AP7315D-26FS4-7B is a parametric equivalent with identical output voltage, current rating, dropout voltage, quiescent current, PSRR, package type, and operating temperature range. The D suffix indicates a die variant from Diodes Incorporated but does not affect functional performance or pin compatibility.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 4-XDFN Exposed Pad package (X2-DFN1010-4) with identical pinout and mechanical dimensions. PCB layout and footprint remain unchanged when substituting between these parts.

Q: What compliance certifications apply to both parts?

A: Both AP7315-26FS4-7B and AP7315D-26FS4-7B are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification and HTSUS code 8542.39.0001.

Q: Is there a difference in quiescent current or power dissipation between these parts?

A: No. Both parts specify identical quiescent current of 60 µA and maximum supply current of 100 µA, resulting in equivalent power dissipation characteristics.

Q: Can these parts be used interchangeably in production?

A: Yes. Both parts are active production devices with identical electrical specifications, mechanical compatibility, and regulatory compliance. They are suitable for direct substitution in manufacturing and design applications.
