Substitute Part Grouping Explanation

Substitute parts for the AP7361-12ER-13 are identified based on the following critical parameters that determine functional equivalence:

Output voltage fixed at 1.2V
Maximum input voltage of 6V
Surface Mount packaging with TO-261-4 or TO-261AA case
Positive output configuration with fixed output type
Active product status
ROHS3 compliance and REACH unaffected status

Two substitute categories are provided: parametric equivalents from the same manufacturer (AP7361-12E-13) and manufacturer-recommended alternatives (MCP1824ST-1202E/DB). Both maintain the core electrical specifications and mechanical compatibility required for direct substitution in applications designed for the AP7361-12ER-13.

Engineering Selection Recommendations

AP7361-12E-13 is a parametric equivalent from Diodes Incorporated with identical electrical specifications and output current rating of 1A. This part differs only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and maintains full compatibility with designs specified for the AP7361-12ER-13. Both parts are Active status with ROHS3 compliance and REACH unaffected certification.

MCP1824ST-1202E/DB from Microchip Technology is a manufacturer-recommended alternative with the same fixed 1.2V output and 6V maximum input voltage. This part operates across an extended temperature range (-40°C ~ 125°C) compared to the primary part. However, the output current is rated at 300mA, which is lower than the 1A specification of the AP7361-12ER-13. Selection of this part requires verification that application current requirements do not exceed 300mA. The MCP1824ST-1202E/DB is Active status with ROHS3 compliance and REACH unaffected certification.

Frequently Asked Questions (FAQ)

Q: Can AP7361-12E-13 be used as a direct replacement for AP7361-12ER-13?

A: Yes. Both parts are from Diodes Incorporated with identical electrical specifications including 1.2V fixed output, 1A output current, 0.7V maximum dropout voltage, and -40°C to 85°C operating temperature range. The difference is packaging format: AP7361-12E-13 is supplied in Tape & Reel format while AP7361-12ER-13 is supplied in Cut Tape & Digi-Reel® format. Electrical performance and mechanical compatibility are equivalent.

Q: What are the limitations of using MCP1824ST-1202E/DB as a substitute?

A: The MCP1824ST-1202E/DB has a maximum output current of 300mA, compared to 1A for the AP7361-12ER-13. Applications requiring output currents above 300mA cannot use this part. The MCP1824ST-1202E/DB is suitable only for designs with current requirements at or below 300mA. All other electrical parameters including output voltage, input voltage range, and package compatibility are maintained.

Q: Are all substitute parts in the same package?

A: Yes. All three parts use the same TO-261-4 and TO-261AA case package with Surface Mount mounting type. PCB layout and footprint compatibility are maintained across all substitutes.

Q: Do all parts meet the same compliance standards?

A: Yes. AP7361-12ER-13, AP7361-12E-13, and MCP1824ST-1202E/DB are all ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level is 1 (Unlimited) for all parts.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) & Digi-Reel® is a smaller quantity packaging format suitable for lower-volume applications. Tape & Reel (TR) is a continuous reel format optimized for high-volume automated assembly. Electrical specifications and component performance are identical; packaging format affects only supply chain and handling logistics.
