AP7315D-26FS4-7B Equivalent & Substitute Parts

Part Overview

The AP7315D-26FS4-7B is a linear voltage regulator IC manufactured by Diodes Incorporated, designed for positive fixed output applications. This device delivers 150mA output current with a fixed 2.6V output and operates across an input voltage range up to 5.25V. The regulator features integrated over-current protection and operates reliably across the industrial temperature range of -40°C to 85°C. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, this component is suitable for applications requiring stable low-voltage regulation in compact surface-mount form factors. Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7315D-26FS4-7B are identified based on strict electrical and mechanical parameter matching. The critical parameters that determine substitution eligibility are:

• Fixed output voltage of 2.6V
• Output current rating of 150mA
• Maximum input voltage of 5.25V
• Voltage dropout specification of 0.32V @ 150mA
• Quiescent current of 60 µA
• PSRR of 75dB (1kHz)
• Over-current protection feature
• Operating temperature range of -40°C to 85°C
• 4-XDFN Exposed Pad package configuration
• Surface mount mounting type

Parts meeting all these parameters are classified as direct parametric equivalents and may be used interchangeably in circuit designs without modification to the application schematic or PCB layout.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7315D-26FS4-7B and AP7315-26FS4-7B are active products from Diodes Incorporated with identical electrical and mechanical specifications. Both devices carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications. The parts are functionally interchangeable for all applications requiring a 2.6V, 150mA linear regulator in the X2-DFN1010-4 package. Selection between these parts may be based on inventory availability and lead time considerations, as no technical differentiation exists between them.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical specifications, including output voltage, current rating, dropout voltage, quiescent current, and PSRR. Both use the same 4-XDFN Exposed Pad package and operate across the same temperature range. No circuit modifications or PCB layout changes are required.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. Both parts use the identical X2-DFN1010-4 package configuration with 4-XDFN Exposed Pad. PCB footprints, solder pad layouts, and mounting procedures are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AP7315D-26FS4-7B and AP7315-26FS4-7B are ROHS3 compliant and REACH unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the voltage dropout specification?

A: The 0.32V dropout at 150mA maximum output current defines the minimum input voltage required to maintain regulation at full load. This specification is identical across both parts.

Q: Are these parts suitable for battery-powered applications?

A: Both parts operate with input voltages up to 5.25V and feature low quiescent current of 60 µA, making them suitable for battery-powered applications requiring stable 2.6V regulation.
