AP1086T25G-U Equivalent & Substitute Parts

Part Overview

The AP1086T25G-U is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. It delivers a fixed positive 2.5V output at 1.5A in a TO-220-3 through-hole package. The device includes integrated over-current and over-temperature protection, with a maximum input voltage of 12V and a dropout voltage of 1.4V at full load current.

This part is marked as obsolete, making substitute components necessary for new designs or production continuity. Equivalent alternatives must maintain the same output voltage, current rating, package form factor, and protection features to ensure direct functional replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP1086T25G-U are qualified based on the following critical parameters:

• Fixed output voltage of 2.5V
• Output current capability of 1.5A minimum
• TO-220-3 package form factor for direct pin compatibility
• Through-hole mounting type
• Integrated over-current and over-temperature protection
• ROHS3 compliance for regulatory alignment

Substitutes are grouped into two categories: parametric equivalents from the same manufacturer (Diodes Incorporated) and manufacturer-recommended alternatives from other suppliers (Microchip Technology). Both categories maintain electrical and mechanical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

AP1086T25L-U (Diodes Incorporated): This parametric equivalent maintains identical electrical specifications and operating temperature range as the AP1086T25G-U. Both parts are obsolete, making this substitute suitable for legacy system maintenance where existing design validation has been completed. The primary difference is packaging format (tube vs. unspecified for the main part), which does not affect functional performance.

MIC39150-2.5WT (Microchip Technology): This manufacturer-recommended substitute offers enhanced performance characteristics, including a higher maximum input voltage (16V vs. 12V), significantly lower dropout voltage (0.5V vs. 1.4V), and an extended operating temperature range (-40°C to 125°C). The MIC39150-2.5WT includes reverse polarity protection in addition to over-current and over-temperature protection. This part carries active product status, ensuring long-term availability and supply chain stability. All three parts maintain ROHS3 compliance and identical TO-220-3 package specifications for direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can AP1086T25L-U be used as a direct replacement for AP1086T25G-U?

A: Yes. Both parts are from Diodes Incorporated with identical electrical specifications: 2.5V fixed output, 1.5A current rating, 12V maximum input voltage, 1.4V dropout voltage, and 0°C to 125°C operating range. The TO-220-3 package ensures pin-for-pin compatibility. The only difference is packaging format (tube).

Q: What are the advantages of MIC39150-2.5WT over the original AP1086T25G-U?

A: The MIC39150-2.5WT provides three key improvements: (1) higher maximum input voltage of 16V, allowing operation in higher voltage supply systems; (2) lower dropout voltage of 0.5V, reducing power dissipation and heat generation; (3) extended operating temperature range of -40°C to 125°C for wider environmental applications. Additionally, it includes reverse polarity protection and maintains active product status for supply continuity.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the TO-220-3 through-hole package with identical pin configuration, enabling direct board-level substitution without layout modifications.

Q: Which substitute should be selected for new designs?

A: MIC39150-2.5WT is recommended for new designs due to its active product status, superior performance characteristics, and enhanced protection features. For legacy system maintenance, AP1086T25L-U provides equivalent functionality to the obsolete AP1086T25G-U.

Q: Do all substitutes maintain regulatory compliance?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, meeting current regulatory requirements for electronic component distribution and use.
