AP2014ASG-13 Equivalent & Substitute Parts

Part Overview

The AP2014ASG-13 is a buck regulator positive output step-down DC-DC controller IC manufactured by Diodes Incorporated in an 8-SOP package. This component functions as a transistor driver for step-down topology applications with a single output phase. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP2014ASG-13 are identified based on functional equivalence within the buck regulator controller category. The primary substitution criteria are:

Core Functional Parameters:

• Output Type: Transistor Driver
• Function: Step-Down
• Output Configuration: Positive
• Topology: Buck
• Number of Outputs: 1
• Output Phases: 1
• Synchronous Rectifier: Yes
• Control Features: Soft Start

Electrical Operating Parameters:

• Supply voltage compatibility (5V, 12V operation)
• Switching frequency range (200kHz to 400kHz)
• Duty cycle capability (90% minimum)
• Operating temperature range (0°C ~ 125°C minimum)

Physical & Compliance Parameters:

• Surface mount technology
• RoHS3 compliance
• MSL 1 rating

Two substitute parts meet these criteria: AP2014SL-13 (parametric equivalent from the same manufacturer) and SP6132HEU-L/TR (manufacturer-recommended alternative from MaxLinear, Inc.).

Parameter Comparison

Engineering Selection Recommendations

AP2014SL-13 (Parametric Equivalent): This part is the direct parametric equivalent from Diodes Incorporated, sharing identical package geometry (8-SOIC), supply voltage range (5V, 12V), duty cycle maximum (90%), and operating temperature range (0°C ~ 125°C). The primary difference is switching frequency (200kHz vs. 400kHz). This part carries Active product status and maintains ROHS3 compliance with MSL 1 rating. Selection of AP2014SL-13 is appropriate for applications where the lower switching frequency is compatible with system requirements and where package footprint compatibility is critical.

SP6132HEU-L/TR (Manufacturer-Recommended Alternative): This MaxLinear part offers expanded supply voltage range (3V ~ 28V), higher maximum duty cycle (100%), and wider operating temperature range (-40°C ~ 85°C). The package differs (10-MSOP vs. 8-SOIC), requiring PCB layout modification. This part carries Active product status and RoHS compliance with MSL 1 rating. Selection of SP6132HEU-L/TR is appropriate for applications requiring extended voltage input range, higher duty cycle capability, or wider temperature operation, provided PCB redesign for the different package footprint is feasible.

Frequently Asked Questions (FAQ)

Q: Can AP2014SL-13 be used as a direct replacement for AP2014ASG-13? A: AP2014SL-13 is functionally equivalent with identical package footprint (8-SOIC) and electrical operating parameters (5V, 12V supply; 0°C ~ 125°C operating range; 90% max duty cycle). The switching frequency differs (200kHz vs. 400kHz). Direct PCB substitution is possible if the lower switching frequency is compatible with the application design.

Q: What are the key differences between AP2014SL-13 and SP6132HEU-L/TR? A: Both parts function as buck regulator controllers with soft start and synchronous rectification. AP2014SL-13 maintains the original 8-SOIC package and 5V/12V supply range. SP6132HEU-L/TR uses a 10-MSOP package and supports wider supply voltage (3V ~ 28V) and higher duty cycle (100%). Package change requires PCB redesign.

Q: Does package size difference affect substitution feasibility? A: Yes. AP2014SL-13 uses the same 8-SOIC package as the original part and can be substituted without PCB modification. SP6132HEU-L/TR uses a 10-MSOP package with different pin count and footprint, requiring PCB layout redesign and schematic verification.

Q: Are all substitute parts RoHS compliant? A: Yes. AP2014SL-13 is ROHS3 compliant. SP6132HEU-L/TR is RoHS compliant. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute part should be selected for new designs? A: Selection depends on application requirements. For designs requiring identical package footprint and supply voltage range, AP2014SL-13 is appropriate. For designs requiring extended voltage input range (3V ~ 28V), higher duty cycle (100%), or wider temperature operation (-40°C ~ 85°C), SP6132HEU-L/TR is appropriate, provided PCB redesign is feasible.
