AP7361-12D-13 Equivalent & Substitute Parts

Part Overview

The AP7361-12D-13 is a linear voltage regulator IC manufactured by Diodes Incorporated, designed for positive fixed output applications. This Surface Mount device delivers 1A output current at a fixed 1.2V output voltage with a maximum dropout voltage of 0.7V at rated current. The part is Active in product status and widely used in power management applications requiring stable low-voltage regulation. Substitute parts are identified to provide design flexibility, inventory alternatives, or end-of-life mitigation for applications where the original part becomes unavailable or when design requirements permit functional equivalents.

Substitute Part Grouping Explanation

The BD12KA5FP-E2 manufactured by Rohm Semiconductor is identified as a substitute for the AP7361-12D-13 based on the following substitution criteria:

Matching Parameters:

• Fixed output voltage: 1.2V
• Output configuration: Positive
• Package type: TO-252-3 (DPAK, 2 Leads + Tab, SC-63)
• Mounting type: Surface Mount
• Protection features: Over Current, Over Temperature
• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• Product status: Active

Differing Parameters:

• Maximum input voltage: 5.5V (substitute) vs. 6V (main part)
• Output current: 500mA (substitute) vs. 1A (main part)
• Quiescent current: 0.35 mA (substitute) vs. 90 µA (main part)
• Operating temperature range: -40°C ~ 105°C (substitute) vs. -40°C ~ 85°C (main part)
• PSRR: 50dB @ 120Hz (substitute) vs. 65dB ~ 45dB @ 1kHz ~ 10kHz (main part)

Substitution is valid only for applications where the output current requirement does not exceed 500mA and the input voltage remains below 5.5V.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7361-12D-13 and BD12KA5FP-E2 are Active products with ROHS3 compliance and identical MSL ratings, making them suitable for equivalent applications within specified parameter limits. The BD12KA5FP-E2 is appropriate for designs where output current does not exceed 500mA and input voltage remains at or below 5.5V. The AP7361-12D-13 is required for applications demanding the full 1A output current capability or input voltages up to 6V. Both devices provide identical package footprints (TO-252-3) and support identical output voltage (1.2V), enabling direct PCB layout compatibility when electrical requirements align. Selection between these parts must be based on the specific current and voltage requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the BD12KA5FP-E2 be used as a direct replacement for the AP7361-12D-13 in all applications?

A: No. The BD12KA5FP-E2 has a maximum output current of 500mA compared to the AP7361-12D-13's 1A rating. Substitution is valid only for applications where the load current does not exceed 500mA. Additionally, the maximum input voltage for the BD12KA5FP-E2 is 5.5V versus 6V for the main part.

Q: Are the packages physically identical?

A: Yes. Both parts use the TO-252-3 package (DPAK with 2 Leads + Tab, SC-63 designation), providing identical PCB footprints and pin configurations. No layout modifications are required for package compatibility.

Q: What is the difference in quiescent current between these parts?

A: The AP7361-12D-13 has a quiescent current of 90 µA, while the BD12KA5FP-E2 has 0.35 mA. The substitute part draws approximately 3.9 times more quiescent current, which may impact battery-powered or ultra-low-power applications.

Q: Do both parts provide the same protection features?

A: Both parts include Over Current and Over Temperature protection. The AP7361-12D-13 additionally provides Short Circuit protection, which the BD12KA5FP-E2 does not specify.

Q: Are both parts RoHS compliant?

A: Yes. Both the AP7361-12D-13 and BD12KA5FP-E2 are ROHS3 compliant with MSL rating 1 (Unlimited), meeting identical environmental and regulatory requirements.

Q: What is the operating temperature range for each part?

A: The AP7361-12D-13 operates from -40°C to 85°C, while the BD12KA5FP-E2 operates from -40°C to 105°C. The substitute part supports a wider high-temperature range.
