AP7315-28SR-7 Equivalent & Substitute Parts

Part Overview

The AP7315-28SR-7 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This positive fixed output regulator delivers 150mA at 2.8V with a maximum dropout voltage of 0.29V at rated current. The device is housed in a SOT-23-3 surface mount package and is actively produced. Substitute parts are identified when electrical performance, mechanical compatibility, and regulatory compliance remain equivalent across the specified parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP7315-28SR-7 is determined by equivalence across the following critical parameters:

• Output voltage configuration (Positive, Fixed, 2.8V)
• Output current capability (150mA)
• Maximum input voltage (5.25V)
• Dropout voltage performance (0.29V @ 150mA)
• Package type (SOT-23-3)
• Operating temperature range (-40°C ~ 85°C)
• Regulatory compliance (ROHS3, REACH Unaffected)

The AP7315-28SA-7 meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, the same package footprint, and equivalent regulatory certifications. The difference between these parts lies in the packaging format: the SR variant uses Tape & Reel (TR) packaging, while the SA variant also uses Tape & Reel (TR) packaging, making them interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7315-28SR-7 and AP7315-28SA-7 are active products from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Packaging format availability and supply chain requirements
• Inventory levels at the time of procurement
• Compliance certifications: both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements
• Moisture sensitivity classification (MSL 1) indicates unlimited shelf life under standard storage conditions

No technical performance differentiation exists between these parts. Component selection can proceed based on procurement logistics and availability.

Frequently Asked Questions (FAQ)

Q: Can AP7315-28SA-7 be used as a direct replacement for AP7315-28SR-7?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (2.8V), output current (150mA), dropout voltage (0.29V @ 150mA), and SOT-23-3 package footprint. They are electrically and mechanically interchangeable.

Q: What is the difference between the SR and SA designations?

A: The SR and SA designations indicate different packaging formats within the Diodes Incorporated AP7315 product line. Both use Tape & Reel (TR) packaging. The difference does not affect electrical performance or PCB compatibility.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the AP7315-28SR-7 and AP7315-28SA-7 operate across the identical temperature range of -40°C to 85°C.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 1 (unlimited shelf life) for both variants.

Q: What is the maximum input voltage for these regulators?

A: The maximum input voltage for both the AP7315-28SR-7 and AP7315-28SA-7 is 5.25V.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that the packaging format (Tape & Reel) meets your assembly requirements. No circuit redesign or PCB layout modification is necessary when substituting between these parts.
