AP7361-25D-13 Equivalent & Substitute Parts

Part Overview

The AP7361-25D-13 is a linear voltage regulator IC manufactured by Diodes Incorporated, designed to deliver a fixed 2.5V output at 1A maximum current. This positive fixed output regulator operates across an input voltage range up to 6V with a maximum dropout voltage of 0.7V at full load. The device is housed in a TO-252-3 (DPAK) surface mount package and is currently in active production status with 2600 units available in inventory.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to supply constraints, inventory availability, or when system specifications permit operation within the electrical and mechanical tolerances of alternative components.

Substitute Part Grouping Explanation

Substitute parts for the AP7361-25D-13 are qualified based on the following critical parameters that determine functional compatibility:

Output Voltage Match: All substitute parts must provide a fixed 2.5V output to maintain circuit voltage requirements.

Package Compatibility: All substitute parts must use the TO-252-3 (DPAK) surface mount package to ensure PCB layout compatibility without redesign.

Output Current Capability: Substitute parts must support the required load current within system design margins. The AP7361-25D-13 delivers 1A; substitutes with lower current ratings (500mA) are acceptable only when system load requirements do not exceed the substitute's maximum output current specification.

Input Voltage Range: Substitute parts must accommodate the system input voltage up to the specified maximum without exceeding absolute maximum ratings.

Protection Features: All qualified substitutes include over-current, over-temperature, and short-circuit protection to maintain system reliability.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Parameter Comparison

Engineering Selection Recommendations

AP7361-25D-13 (Primary Component): Select this part when system load current requirements reach or approach 1A. The device offers superior quiescent current performance (90 µA) and higher PSRR specification, making it suitable for noise-sensitive applications. Active production status and 2600-unit inventory availability support reliable procurement.

BD25KA5FP-E2 (Substitute Component): This Rohm Semiconductor alternative is suitable for applications where maximum output current does not exceed 500mA. The substitute provides lower dropout voltage (0.2V @ 200mA) and extended operating temperature range (-40°C to 105°C). Both components maintain identical ROHS3 compliance and REACH unaffected status. The substitute's soft-start protection feature provides additional inrush current limiting during power-up sequences.

Both components are active production devices with current inventory availability. Selection between primary and substitute parts depends on load current requirements and thermal operating conditions specific to the application.

Frequently Asked Questions (FAQ)

Q: Can BD25KA5FP-E2 replace AP7361-25D-13 in all applications?

A: No. The BD25KA5FP-E2 is rated for maximum 500mA output current, while the AP7361-25D-13 delivers 1A. Substitution is valid only when system load current remains below 500mA. Exceeding this limit will cause the substitute device to enter current-limit protection or thermal shutdown.

Q: Are the packages identical between these parts?

A: Yes. Both components use the TO-252-3 (DPAK) surface mount package with identical pinout and PCB footprint. No layout modifications are required for physical substitution.

Q: What is the impact of the lower quiescent current in the AP7361-25D-13?

A: The AP7361-25D-13 draws 90 µA quiescent current compared to 550 µA for the BD25KA5FP-E2. In battery-powered or low-power standby applications, the lower quiescent current of the primary part reduces parasitic power consumption and extends battery life.

Q: Does the extended temperature range of BD25KA5FP-E2 make it superior?

A: The extended range (-40°C to 105°C versus -40°C to 85°C) is beneficial only for applications operating above 85°C. For standard industrial temperature ranges, both devices are equivalent. Selection should be based on actual application temperature requirements.

Q: How do the PSRR specifications compare?

A: The AP7361-25D-13 provides 65dB at 1kHz and 45dB at 10kHz, while the BD25KA5FP-E2 provides 50dB at 120Hz. The primary part offers superior high-frequency noise rejection, making it preferable for RF or sensitive analog circuits. The substitute is adequate for general-purpose power supply applications.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.
