AP7175MP-13 Equivalent & Substitute Parts

Part Overview

The AP7175MP-13 is a linear voltage regulator IC from Diodes Incorporated designed for positive adjustable output applications. This surface-mount component delivers 3A output current with adjustable voltage regulation from 0.8V to 3.23V. The device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The AP7175MP-13 operates across the industrial temperature range of -40°C to 85°C and includes integrated protection features for over-current, over-temperature, and short-circuit conditions.

• Voltage dropout: 0.42V or lower at 3A
• Control features: Enable and Power Good functionality
• Protection features: Over-current and over-temperature protection minimum
• Package compatibility: Surface-mount 8-pin configurations with exposed pad
• Compliance: ROHS3 compliant

Identified Substitutes:

1. AP7176BMP-13 (Diodes Incorporated) – Same manufacturer, active product status, identical electrical specifications with enhanced protection features
2. MIC59300YME-TR (Microchip Technology) – Cross-manufacturer substitute with compatible electrical performance and extended temperature range

Parameter Comparison

Engineering Selection Recommendations

AP7176BMP-13 (Diodes Incorporated): This substitute is the primary recommendation for direct replacement of the obsolete AP7175MP-13. Both devices share identical electrical specifications, the same 8-MSOP package footprint, and equivalent control/protection features. The AP7176BMP-13 carries active product status with manufacturer support and availability. The addition of Power On Reset (POR) protection provides enhanced system reliability. ROHS3 compliance and MSL 1 rating match the original specification.

MIC59300YME-TR (Microchip Technology): This cross-manufacturer substitute meets the core electrical requirements with comparable output current, voltage regulation range, and protection features. The device offers superior dropout performance (0.4V vs. 0.42V) and extended operating temperature range (-40°C to 125°C). However, the 8-SOIC package is physically larger (0.154" vs. 0.118" width) and requires PCB layout modification. The MSL 3 rating requires controlled storage conditions. This option is suitable for applications where package size change is acceptable and extended temperature operation is beneficial.

Frequently Asked Questions (FAQ)

Q: Can AP7176BMP-13 be used as a direct replacement for AP7175MP-13? A: Yes. Both devices are housed in the 8-MSOP package with identical pinout and electrical specifications. No circuit modifications are required. The AP7176BMP-13 is the recommended substitute due to active product status and manufacturer support.

Q: What are the key differences between AP7176BMP-13 and MIC59300YME-TR? A: The primary differences are package type (8-MSOP vs. 8-SOIC), maximum output voltage (3.12V vs. 3.3V), dropout voltage (0.53V vs. 0.4V), operating temperature range (-40°C to 85°C vs. -40°C to 125°C), and moisture sensitivity level (MSL 1 vs. MSL 3). The MIC59300YME-TR requires PCB layout changes due to different package dimensions.

Q: Is the MIC59300YME-TR suitable for my application if I need the same package footprint? A: No. The MIC59300YME-TR uses an 8-SOIC package (0.154" width) compared to the 8-MSOP package (0.118" width) of the AP7175MP-13. PCB redesign would be necessary. For footprint compatibility, use AP7176BMP-13.

Q: What is the impact of the higher dropout voltage in AP7176BMP-13? A: The AP7176BMP-13 has a maximum dropout of 0.53V @ 3A compared to 0.42V for the AP7175MP-13. This 0.11V difference may affect minimum input voltage requirements in power-constrained applications. Verify that your input voltage headroom accommodates this specification.

Q: Are all three parts ROHS3 compliant? A: Yes. AP7175MP-13, AP7176BMP-13, and MIC59300YME-TR are all ROHS3 compliant. All three parts meet REACH requirements and carry EAR99 ECCN classification.

Q: What is the significance of MSL rating differences? A: AP7175MP-13 and AP7176BMP-13 have MSL 1 (unlimited shelf life). MIC59300YME-TR has MSL 3, requiring storage below 30°C and 60% relative humidity for up to 168 hours after moisture exposure. MSL 3 components require more careful handling and storage management.

Q: Does the Power On Reset (POR) feature in AP7176BMP-13 affect circuit design? A: The POR feature in AP7176BMP-13 provides automatic reset functionality during power-up sequences. This is an enhancement that does not negatively impact existing designs. Verify that your application benefits from or is compatible with automatic power-on reset behavior.
