AP7315D-295FS4-7B Equivalent & Substitute Parts

Part Overview

The AP7315D-295FS4-7B 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 2.95V output voltage and is housed in a 4-XDFN Exposed Pad surface mount package. The regulator operates across an input voltage range up to 5.25V with a maximum dropout voltage of 0.29V at full load current. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1), making it suitable for industrial and commercial applications requiring stable low-voltage regulation.

Equivalent and substitute parts are identified based on matching electrical specifications, output configuration, package type, and compliance certifications to ensure direct functional interchangeability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7315D-295FS4-7B are identified through strict parametric matching of electrical and mechanical specifications. The substitution criteria are based on the following key parameters:

Output voltage specification (2.95V fixed), output current capability (150mA), input voltage maximum rating (5.25V), dropout voltage performance (0.29V @ 150mA), quiescent current (60 µA), package type (4-XDFN Exposed Pad), surface mount configuration, operating temperature range (-40°C ~ 85°C), protection features (Over Current), and compliance certifications (RoHS3, REACH Unaffected).

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The AP7315-295FS4-7B variant differs only in the device designation prefix but maintains identical electrical performance and package specifications, confirming full interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7315D-295FS4-7B and AP7315-295FS4-7B are active production parts from Diodes Incorporated with identical electrical specifications and package configurations. Both parts carry RoHS3 compliance certification and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. The parts are functionally interchangeable with no performance differentiation. Selection between these variants may be based on inventory availability or supplier preference, as both deliver equivalent performance in 2.95V fixed output linear regulation applications requiring 150mA output current capacity.

Frequently Asked Questions (FAQ)

Q: Can AP7315-295FS4-7B be used as a direct replacement for AP7315D-295FS4-7B?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (2.95V), output current (150mA), dropout voltage (0.29V @ 150mA), package type (4-XDFN Exposed Pad), and operating temperature range (-40°C ~ 85°C). They are direct substitutes.

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

A: No. Both parts use the identical 4-XDFN Exposed Pad package (X2-DFN1010-4) with surface mount configuration. Pinout and PCB layout compatibility are maintained.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AP7315D-295FS4-7B and AP7315-295FS4-7B are RoHS3 compliant and REACH Unaffected, with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the significance of the "D" designation in AP7315D-295FS4-7B?

A: The "D" prefix is a device designation variant within the AP7315 series. It does not indicate functional or electrical differences. Both AP7315D and AP7315 variants with matching output voltage and current specifications are equivalent.

Q: Can these regulators be used in applications requiring higher output current?

A: No. Both parts are rated for 150mA maximum output current. Applications requiring higher current must use alternative regulator models with higher current ratings.

Q: What is the quiescent current specification and why is it important?

A: Quiescent current is 60 µA, representing the regulator's internal supply current when no load is connected. This parameter is critical for battery-powered or low-power standby applications where minimizing idle current consumption is necessary.
