Substitute Part Grouping Explanation

Substitute parts for the AP7361-15E-13 are classified based on strict electrical and mechanical parameter equivalence:

Parametric Equivalent (Same Manufacturer): AP7361-15ER-13 maintains identical electrical specifications and output configuration. The primary distinction is the package variant designation (SOT-223R vs. SOT-223-3), which represents a packaging revision within the same product family. Both are manufactured by Diodes Incorporated and share the same base product number AP7361.

Manufacturer Recommended Equivalents (Cross-Manufacturer): MIC37100-1.5WS and MIC37100-1.5WS-TR (Microchip Technology) provide electrical equivalence with the following key parameters matched: 1.5V fixed output, 1A output current, 6V maximum input voltage, SOT-223-3 package, Surface Mount configuration, and Active product status. These parts differ in packaging format (Tube vs. Tape & Reel) and feature improved dropout voltage (0.5V @ 1A vs. 0.7V @ 1A) and extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C).

Substitution eligibility is determined by: matching output voltage and current ratings, compatible package/case specifications, equivalent protection features, and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Engineering Selection Recommendations

AP7361-15ER-13: Direct parametric equivalent within the Diodes Incorporated product family. Suitable for applications where manufacturer continuity is preferred. Package variant (SOT-223R) is mechanically compatible with SOT-223-3 footprints. Both parts maintain identical electrical performance and protection feature sets.

MIC37100-1.5WS-TR: Recommended for applications requiring Tape & Reel packaging format. Offers improved dropout voltage performance (0.5V vs. 0.7V @ 1A) and extended operating temperature range (-40°C ~ 125°C). Maintains Active product status and full compliance certifications. Suitable for high-volume production environments.

MIC37100-1.5WS: Equivalent electrical performance to MIC37100-1.5WS-TR with Tube packaging format. Appropriate for lower-volume applications or where Tube packaging is specified. Identical electrical and thermal specifications.

All substitute parts are Active status products with current manufacturing support and full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can AP7361-15ER-13 be used as a direct replacement for AP7361-15E-13?

A: Yes. Both parts share identical electrical specifications, output voltage (1.5V), output current (1A), dropout voltage (0.7V @ 1A), operating temperature range (-40°C ~ 85°C), and protection features. The package variant designation (SOT-223R vs. SOT-223-3) represents a packaging revision within the same product family and is mechanically compatible.

Q: What are the key differences between Diodes Incorporated and Microchip Technology substitutes?

A: The Microchip MIC37100 series offers improved dropout voltage (0.5V @ 1A vs. 0.7V @ 1A) and extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C). All other electrical parameters, output voltage, output current, input voltage maximum, package type (SOT-223-3), and protection features remain equivalent. Both manufacturers provide Active status products with full compliance certifications.

Q: Does packaging format (Tape & Reel vs. Tube) affect electrical performance?

A: No. Packaging format (Tape & Reel vs. Tube) is a supply chain and handling specification only. MIC37100-1.5WS (Tube) and MIC37100-1.5WS-TR (Tape & Reel) are electrically identical. Selection depends on production volume requirements and assembly process specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. AP7361-15E-13, AP7361-15ER-13, MIC37100-1.5WS, and MIC37100-1.5WS-TR are all ROHS3 compliant and REACH Unaffected, meeting regulatory requirements for restricted substance use.

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

A: Yes, provided the PCB footprint accommodates the package type. AP7361-15E-13 and AP7361-15ER-13 use SOT-223-3 and SOT-223R packages respectively, which are mechanically compatible. MIC37100 series parts use SOT-223-3 package, matching the primary part. Verify footprint compatibility with your PCB design specifications before implementation.
