AP7313-25SAG-7 Equivalent & Substitute Parts

Part Overview

The AP7313-25SAG-7 is a linear voltage regulator IC from Diodes Incorporated designed for positive fixed output applications. This Surface Mount device delivers 150mA output current at a fixed 2.5V output with a maximum dropout voltage of 0.3V at rated current. The part is Active status and widely used in power management applications requiring low-noise, regulated DC supply. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7313-25SAG-7 are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

• Output voltage (fixed at 2.5V)
• Output current capability (150mA)
• Maximum input voltage (6V)
• Dropout voltage performance (0.3V @ 150mA)
• Quiescent current specification (75 µA)
• PSRR performance (65dB @ 100Hz)
• Protection features (Over Current, Over Temperature, Short Circuit)
• Operating temperature range (-40°C ~ 85°C)
• Package type (SOT-23-3)
• Compliance certifications (ROHS3, REACH Unaffected)

The AP7313-25SRG-7 meets all these criteria and is classified as a parametric equivalent. The primary distinction is the supplier device package designation (SOT23R versus SOT-23-3), which represents a packaging variant of the same physical form factor suitable for identical PCB footprints.

Parameter Comparison

Engineering Selection Recommendations

Both AP7313-25SAG-7 and AP7313-25SRG-7 are Active status products from Diodes Incorporated with identical electrical specifications and compliance certifications. Selection between these parts is based on packaging availability and supply chain considerations rather than functional differences.

The AP7313-25SAG-7 is available with 1943 pieces in stock, while the AP7313-25SRG-7 offers higher inventory availability at 19530 pieces. Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical MSL ratings. The supplier device package designation difference (SOT-23-3 versus SOT23R) does not affect PCB footprint compatibility or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can AP7313-25SRG-7 be used as a direct replacement for AP7313-25SAG-7?

A: Yes. Both parts share identical electrical specifications, output voltage, current rating, dropout voltage, protection features, and operating temperature range. The package designation difference represents a supplier packaging variant with no functional impact.

Q: Are there any PCB layout considerations when substituting between these parts?

A: No. Both parts use the SOT-23-3 package form factor with identical pinout and footprint requirements. No PCB redesign is necessary.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both AP7313-25SAG-7 and AP7313-25SRG-7 are ROHS3 compliant, REACH Unaffected, and carry identical MSL ratings of 1 (Unlimited).

Q: What is the difference between the part numbers?

A: The difference lies in the supplier device package designation. AP7313-25SAG-7 uses SOT-23-3 designation, while AP7313-25SRG-7 uses SOT23R designation. Both represent the same physical package suitable for identical applications.

Q: Which part should be selected based on availability?

A: Selection should be based on supply chain requirements and lead time. AP7313-25SRG-7 offers significantly higher inventory availability. Both parts are functionally equivalent for all electrical and mechanical parameters.
