AP1513SG-U Equivalent & Substitute Parts

Part Overview

The AP1513SG-U is a buck switching regulator IC from Diodes Incorporated designed for positive adjustable output applications. This device delivers 2A output current with an adjustable output voltage range from 0.8V to 18V, operating from a 3.6V to 18V input supply. The AP1513SG-U is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The AP1513SG-13 qualifies as a direct substitute for the AP1513SG-U based on the following critical parameters:

• Identical manufacturer (Diodes Incorporated)
• Identical base product number (AP1513)
• Matching electrical specifications: input voltage range (3.6V–18V), output voltage range (0.8V–18V), output current (2A), and switching frequency (300kHz)
• Identical package and case designation (8-SOIC, 0.154" width)
• Identical mounting type (Surface Mount)
• Identical operating temperature range (-20°C ~ 85°C)
• Identical RoHS3 compliance status

The primary distinction is product status: AP1513SG-U is obsolete, while AP1513SG-13 is active with significantly higher inventory availability (52,600 pcs vs. 672 pcs).

Parameter Comparison

Engineering Selection Recommendations

The AP1513SG-13 is the direct functional equivalent of the AP1513SG-U. Selection of AP1513SG-13 is supported by:

• Active product status ensuring long-term availability and supply chain stability
• Identical electrical and mechanical specifications enabling direct PCB-level substitution
• Superior moisture sensitivity rating (MSL 1 vs. MSL 3), providing enhanced reliability in storage and handling
• ROHS3 compliance maintained across both variants
• Significantly higher inventory availability (52,600 pcs) compared to the obsolete AP1513SG-U (672 pcs)

For new designs or redesigns of existing applications using AP1513SG-U, AP1513SG-13 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can AP1513SG-13 be used as a direct replacement for AP1513SG-U in existing designs?

A: Yes. Both parts share identical electrical specifications (input/output voltage ranges, output current, switching frequency), operating temperature range, and 8-SOIC package dimensions. No circuit modifications are required.

Q: What is the difference between AP1513SG-U and AP1513SG-13?

A: The primary differences are product status (obsolete vs. active), inventory availability, and moisture sensitivity level. AP1513SG-13 has a superior MSL rating (1 vs. 3), indicating better performance in humid storage conditions.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications. No compliance-related barriers to substitution exist.

Q: What packaging options are available for AP1513SG-13?

A: AP1513SG-13 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production-volume procurement.

Q: Is the 8-SOIC package footprint identical between both parts?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical Surface Mount mounting type, ensuring PCB layout compatibility.
