AP65200SP-13 Equivalent & Substitute Parts

Part Overview

The AP65200SP-13 is a buck switching regulator IC manufactured by Diodes Incorporated, designed for positive adjustable step-down voltage regulation with a 2A output current capability. This component operates across an input voltage range of 4.7V to 18V and delivers adjustable output voltage from 0.925V to 16V at a switching frequency of 340kHz with integrated synchronous rectification.

The AP65200SP-13 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications utilizing this regulator topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP65200SP-13 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Buck topology with positive adjustable output configuration
• Single output channel
• Switching frequency of 340kHz
• Synchronous rectification capability
• Output voltage adjustment range minimum of 0.925V
• Operating temperature range of -40°C to 85°C

Mechanical Compatibility Requirements:

• 8-SOIC package with exposed pad (0.154", 3.90mm width)
• Surface mount mounting type

Regulatory & Compliance Requirements:

• ROHS3 compliance
• REACH unaffected status

The MP2307DN-LF-Z from Monolithic Power Systems Inc. meets all electrical, mechanical, and regulatory criteria for substitution. While the MP2307DN-LF-Z offers enhanced specifications (3A output current, extended input voltage to 23V, and extended output voltage to 20V), these improvements maintain backward compatibility with the AP65200SP-13 design envelope.

Parameter Comparison

Engineering Selection Recommendations

The MP2307DN-LF-Z is a direct functional substitute for the AP65200SP-13 based on matching electrical topology, package form factor, and regulatory compliance. Both components are classified as legacy products (obsolete and not for new designs, respectively), indicating limited long-term availability.

Selection of the MP2307DN-LF-Z provides the following advantages:

• Identical package footprint enabling direct PCB compatibility
• Matching switching frequency and control architecture
• Enhanced current rating (3A vs. 2A) providing design margin
• Extended input and output voltage ranges supporting broader application flexibility
• ROHS3 and REACH compliance alignment

For applications currently designed around the AP65200SP-13, the MP2307DN-LF-Z operates within the same electrical operating envelope while offering improved performance headroom. Schematic and layout modifications are not required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the MP2307DN-LF-Z directly replace the AP65200SP-13 without PCB modifications?

A: Yes. Both components use identical 8-SOIC exposed pad packaging with matching pinout and electrical characteristics. Direct footprint substitution is possible without PCB layout changes.

Q: What is the significance of the higher 3A current rating on the MP2307DN-LF-Z compared to the 2A rating of the AP65200SP-13?

A: The MP2307DN-LF-Z supports higher output current delivery. In applications designed for 2A operation, this provides additional thermal and electrical margin. Thermal management and PCB copper area should be verified for the specific application.

Q: Are there differences in control loop behavior or frequency response between these parts?

A: Both components operate at 340kHz switching frequency with synchronous rectification. Detailed control loop characteristics are not provided in the parameter set. Application-specific performance validation is recommended for critical control applications.

Q: Why is the MP2307DN-LF-Z classified as "Not For New Designs"?

A: This classification indicates the manufacturer is not recommending this part for new product development. For legacy system support and replacement applications, it remains a valid substitute for the obsolete AP65200SP-13.

Q: What packaging options are available for the MP2307DN-LF-Z?

A: The MP2307DN-LF-Z is supplied in Cut Tape (CT) and Digi-Reel packaging formats. Verify packaging availability with your supplier for production volume requirements.

Q: Are there any moisture sensitivity considerations for these components?

A: The AP65200SP-13 has MSL 1 (unlimited moisture sensitivity level), while the MP2307DN-LF-Z has MSL 2A (4 weeks). Standard moisture control procedures during storage and assembly are recommended for the MP2307DN-LF-Z.
