AP7361-28ER-13 Equivalent & Substitute Parts

Part Overview

The AP7361-28ER-13 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a fixed 2.8V output at 1A maximum current in a surface-mount SOT-223R package. The part is actively produced and widely stocked, with 939 units available in new original condition. Alternative equivalent parts are necessary when tape & reel packaging specifications differ, when inventory constraints occur, or when design revisions require package format changes while maintaining electrical performance.

Substitute Part Grouping Explanation

Substitution of the AP7361-28ER-13 is determined by the following critical parameters:

Fixed output voltage of 2.8V
Maximum output current of 1A
Maximum input voltage of 6V
Voltage dropout specification of 0.7V @ 1A
Quiescent current of 90 µA
Protection features: Over Current, Over Temperature, Short Circuit
Operating temperature range of -40°C ~ 85°C
Surface-mount package format (SOT-223 family)
Active product status and ROHS3 compliance

The AP7361-28E-13 qualifies as a parametric equivalent because it maintains identical electrical specifications across all critical parameters. The distinction between these parts lies in the supplier device package designation: the main part uses SOT-223R (tape & reel specific marking), while the substitute uses SOT-223-3 (standard SOT-223 three-pin configuration). Both parts share the same base product number (AP7361) and are manufactured by Diodes Incorporated.

Engineering Selection Recommendations

Both the AP7361-28ER-13 and AP7361-28E-13 are active products manufactured by Diodes Incorporated with ROHS3 compliance and identical electrical performance specifications. Selection between these parts is based on packaging and inventory availability:

AP7361-28ER-13: Specified with SOT-223R package designation and tape & reel (TR) format. Current inventory: 939 units.
AP7361-28E-13: Specified with SOT-223-3 package designation and tape & reel (TR) format. Current inventory: 5400 units.

Both parts meet all regulatory requirements (ROHS3 Compliant, REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001) and share identical moisture sensitivity levels (MSL 1 - Unlimited). The choice between these equivalents depends on procurement requirements, packaging specifications for automated assembly, and inventory lead times.

Frequently Asked Questions (FAQ)

Q: Are AP7361-28ER-13 and AP7361-28E-13 electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance with 2.8V fixed output, 1A maximum current, 0.7V dropout at 1A, and 90 µA quiescent current. All protection features and operating temperature ranges are identical.

Q: What is the difference between SOT-223R and SOT-223-3 package designations?

A: Both designations refer to the same physical SOT-223 surface-mount package with three pins (TO-261-4, TO-261AA). The "R" suffix in SOT-223R indicates tape & reel packaging format specific to the part number variant. The functional package dimensions and pin configuration remain identical.

Q: Can I substitute AP7361-28E-13 for AP7361-28ER-13 in production?

A: Yes, provided your assembly process accepts the SOT-223-3 package designation. Both parts are surface-mount compatible with identical pin configurations and electrical specifications. Verify that your bill of materials and assembly documentation can accommodate the package variant designation.

Q: Why would I choose one part over the other?

A: Selection is driven by inventory availability and packaging format requirements. The AP7361-28E-13 has significantly higher stock (5400 units vs. 939 units), making it preferable for high-volume production or when lead times are critical. Choose based on your procurement timeline and assembly equipment specifications.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both AP7361-28ER-13 and AP7361-28E-13 are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.
