AP6015-33M10G-13 Equivalent & Substitute Parts
Part Overview
The AP6015-33M10G-13 is a buck switching regulator IC manufactured by Diodes Incorporated, designed for positive fixed 3.3V output applications with 800mA current capacity. This component operates across a 2.5V to 5.5V input range with a 1MHz switching frequency and integrated synchronous rectification. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure long-term supply availability.

Substitute Part Grouping Explanation
Substitution eligibility for the AP6015-33M10G-13 is determined by the following critical parameters:
- Fixed output voltage of 3.3V
- Minimum output current rating of 800mA
- Buck topology with synchronous rectification
- Surface mount package compatible with 10-TFSOP or 10-MSOP footprint
- Input voltage range compatibility (substitute must accept the 2.5V–5.5V operating range)
- RoHS3 compliance and equivalent environmental certifications
The TPS62056DGSR from Texas Instruments meets these substitution criteria. While the substitute exhibits differences in switching frequency (850kHz vs. 1MHz), input voltage maximum rating (10V vs. 5.5V), and operating temperature range (-40°C to 125°C vs. -40°C to 85°C), these variations remain within acceptable tolerance for functional equivalence in buck regulator applications requiring 3.3V/800mA output.

Engineering Selection Recommendations
The TPS62056DGSR is the designated manufacturer-recommended substitute for the obsolete AP6015-33M10G-13. Selection of this alternative is supported by the following factors:
- Active product status ensures ongoing availability and manufacturing support
- Identical output voltage (3.3V) and current rating (800mA) maintain functional equivalence
- Matching package footprint (10-TFSOP, 10-MSOP) enables direct board-level substitution
- ROHS3 compliance and superior MSL rating (1 vs. 3) provide enhanced environmental and moisture handling characteristics
- Extended operating temperature range (-40°C to 125°C) exceeds the original specification
- Wider input voltage acceptance (2.7V–10V) provides greater design flexibility
The TPS62056DGSR is suitable for direct replacement in applications currently utilizing the AP6015-33M10G-13.
Frequently Asked Questions (FAQ)
Q: Can the TPS62056DGSR be used as a direct replacement for the AP6015-33M10G-13?
A: Yes. Both devices share identical output voltage (3.3V), output current (800mA), package footprint (10-TFSOP, 10-MSOP), and synchronous buck topology. The TPS62056DGSR is the manufacturer-recommended substitute.
Q: What are the key differences between these two parts?
A: The primary differences are switching frequency (850kHz vs. 1MHz), input voltage range (2.7V–10V vs. 2.5V–5.5V), operating temperature range (-40°C to 125°C vs. -40°C to 85°C), and MSL rating (1 vs. 3). These variations do not affect functional substitution for 3.3V/800mA buck regulator applications.
Q: Are there any package compatibility concerns?
A: No. Both parts use the 10-TFSOP, 10-MSOP package with identical 0.118" (3.00mm) width. PCB footprints are compatible without modification.
Q: Does the lower switching frequency of the TPS62056DGSR affect performance?
A: The 850kHz switching frequency of the TPS62056DGSR remains within the range typical for buck regulators in this power class. Output filtering and transient response characteristics may differ slightly, but functional performance for 3.3V/800mA applications remains equivalent.
Q: What is the significance of the MSL rating difference?
A: The TPS62056DGSR carries an MSL rating of 1 (unlimited moisture exposure), compared to the AP6015-33M10G-13 rating of 3 (168 hours). This indicates superior moisture resistance and reduced risk of damage during storage and handling.
Q: Are both parts RoHS compliant?
A: Yes. Both the AP6015-33M10G-13 and TPS62056DGSR are ROHS3 compliant and REACH unaffected.
