AP7315-30FS4-7B Equivalent & Substitute Parts

Part Overview

The AP7315-30FS4-7B is a linear voltage regulator IC manufactured by Diodes Incorporated, designed for power management applications requiring a fixed 3V output at 150mA. This device operates as a positive fixed output regulator with integrated over-current protection, suitable for surface mount applications in the 4-XDFN package format. The part is currently in active production status with 955 units available in new original inventory. 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 of the AP7315-30FS4-7B is based on strict equivalence across the following critical parameters:

• Fixed output voltage of 3V
• Output current capability of 150mA
• Maximum input voltage of 5.25V
• Voltage dropout specification of 0.29V @ 150mA
• Quiescent current of 60 µA
• PSRR of 75dB (1kHz)
• Over-current protection feature
• Operating temperature range of -40°C ~ 85°C
• 4-XDFN Exposed Pad package format
• Surface mount configuration

The AP7315D-30FS4-7B meets all these parameters identically, establishing it as a parametric equivalent. Both parts share the same base product number (AP7315) and supplier device package designation (X2-DFN1010-4), confirming mechanical and electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7315-30FS4-7B and AP7315D-30FS4-7B are active production parts from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than performance differentiation. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL Level 1 rating, confirming suitability for standard manufacturing and storage conditions. The AP7315D-30FS4-7B offers significantly higher inventory availability (110,100 units) compared to the AP7315-30FS4-7B (955 units), making it the preferred choice for high-volume production requirements or extended lead time mitigation.

Frequently Asked Questions (FAQ)

Q: Are the AP7315-30FS4-7B and AP7315D-30FS4-7B electrically interchangeable?

A: Yes. Both parts are parametric equivalents with identical output voltage (3V), output current (150mA), input voltage rating (5.25V max), dropout voltage (0.29V @ 150mA), quiescent current (60 µA), PSRR (75dB at 1kHz), and protection features (over-current). They share the same base product number and supplier device package designation.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts use the identical 4-XDFN Exposed Pad package (X2-DFN1010-4) with surface mount configuration, requiring no PCB layout modifications or footprint changes.

Q: What is the difference between AP7315-30FS4-7B and AP7315D-30FS4-7B?

A: The parts are electrically and mechanically identical. The difference is indicated by the "D" designation in the part number, which typically reflects manufacturing date code or internal Diodes Incorporated product tracking. Both are active production parts with full compliance certifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the AP7315-30FS4-7B and AP7315D-30FS4-7B are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component manufacturing and distribution.

Q: What is the MSL rating for these parts?

A: Both parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or manufacturing processes.

Q: Which part should be selected for new designs?

A: Selection is based on inventory availability and supply chain strategy. The AP7315D-30FS4-7B is recommended for applications requiring higher volume availability or extended production runs due to significantly higher stock levels.
