AP1534SG-13 Equivalent & Substitute Parts

Part Overview

The AP1534SG-13 is a Buck Switching Regulator IC manufactured by Diodes Incorporated, designed for positive adjustable step-down voltage regulation. This active product delivers 2A output current with an adjustable output range from 0.8V to 18V, operating from a 3.6V to 18V input supply. The device is housed in an 8-SOIC surface mount package and operates across the industrial temperature range of -25°C to 85°C. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP1534SG-13 is determined by strict alignment of the following critical parameters:

• Input voltage range: 3.6V to 18V minimum
• Output voltage adjustability: 0.8V to 18V minimum
• Output current capability: 2A minimum
• Switching frequency: 300kHz
• Package type: 8-SOIC surface mount
• Topology: Buck (step-down) configuration
• Output configuration: Positive adjustable

The AP1513SG-13 meets all substitution criteria as a direct equivalent from the same manufacturer, with identical electrical specifications and package configuration. Substitution is valid when the alternative part maintains or exceeds these parameters without degradation of circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Both the AP1534SG-13 and AP1513SG-13 are active products from Diodes Incorporated with ROHS3 compliance and REACH unaffected status. The AP1513SG-13 offers improved moisture sensitivity characteristics (MSL 1 versus MSL 3), providing extended shelf life and reduced risk during storage and handling. However, the AP1534SG-13 maintains a wider minimum operating temperature specification (-25°C versus -20°C), which may be critical for applications requiring extended low-temperature performance. Selection between these parts should be based on specific application requirements regarding environmental storage conditions and operating temperature extremes.

Frequently Asked Questions (FAQ)

Q: Can the AP1513SG-13 be used as a direct replacement for the AP1534SG-13?

A: Yes. Both parts share identical electrical specifications including input voltage range (3.6V–18V), output voltage adjustability (0.8V–18V), output current (2A), switching frequency (300kHz), and package configuration (8-SOIC). The primary difference is the operating temperature minimum (-20°C versus -25°C) and moisture sensitivity level. Substitution is valid for applications operating above -20°C.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: MSL 3 (AP1534SG-13) allows 168 hours of exposure to 85% relative humidity at 85°C before reflow, while MSL 1 (AP1513SG-13) has unlimited shelf life under controlled conditions. The AP1513SG-13 is more tolerant of extended storage and handling in humid environments.

Q: Are both parts pin-compatible?

A: Yes. Both the AP1534SG-13 and AP1513SG-13 use the 8-SOIC (0.154", 3.90mm Width) package with identical pinout and footprint, enabling direct PCB substitution without layout modifications.

Q: Which part should be selected for low-temperature applications?

A: The AP1534SG-13 is specified for operation down to -25°C, while the AP1513SG-13 is specified to -20°C. For applications requiring operation below -20°C, the AP1534SG-13 is the appropriate choice.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
