AP1086D18G-13 Equivalent & Substitute Parts

Part Overview

The AP1086D18G-13 is a linear voltage regulator IC from Diodes Incorporated, delivering a fixed 1.8V output at 1.5A in a TO-252-3 (DPAK) surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The device provides over-current and over-temperature protection suitable for power management applications requiring stable 1.8V regulation from input sources up to 12V.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AP1086D18G-13 is determined by the following critical parameters:

• Fixed output voltage of 1.8V
• Output current capability of 1.5A (minimum requirement)
• TO-252-3 (DPAK) package compatibility
• Surface mount technology
• Over-current and over-temperature protection
• RoHS3 compliance

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical specifications and package form factor, differing only in product status or packaging format (tape & reel vs. bulk).

Manufacturer Recommended Substitutes offer enhanced performance characteristics (higher current capability, improved PSRR, extended input voltage range, or wider operating temperature range) while maintaining the same 1.8V fixed output and compatible package footprint.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent): AP1086D18L-13 is the primary parametric equivalent, offering identical electrical specifications and package footprint. This part is currently active in production and available in tape & reel packaging, making it suitable for immediate substitution in designs currently using AP1086D18G-13.

For Enhanced Performance Applications: LD1086DT18TR (STMicroelectronics) provides superior performance with extended input voltage range (30V maximum) and wider operating temperature range (-40°C to 125°C), along with improved PSRR (82dB). This part maintains 1.5A output current and identical package compatibility.

For Higher Current Capacity: AZ1084CD-1.8TRG1 delivers 5A output current while maintaining the same 1.8V fixed output and TO-252-3 package. This part is suitable for applications requiring higher current delivery from the same footprint.

For Lower Current Applications: LD1117ADT18TR provides 1A output current with improved PSRR (80dB) and extended input voltage range (15V maximum). This part is appropriate for designs with reduced current requirements.

All substitute parts maintain RoHS3 compliance and identical protection features (over-current and over-temperature).

Frequently Asked Questions (FAQ)

Q: Can AP1086D18L-13 be used as a direct replacement for AP1086D18G-13? A: Yes. AP1086D18L-13 is a parametric equivalent with identical output voltage (1.8V), output current (1.5A), package (TO-252-3 DPAK), and protection features. The primary difference is product status (active vs. obsolete) and packaging format (tape & reel vs. bulk).

Q: What is the key difference between AZ1084CD-1.8TRG1 and AP1086D18G-13? A: AZ1084CD-1.8TRG1 provides 5A output current compared to 1.5A in the AP1086D18G-13, while maintaining the same 1.8V output voltage and TO-252-3 package. PSRR is also improved (72dB vs. 60dB). Use this part when higher current capacity is required.

Q: Are all substitute parts compatible with the same PCB footprint? A: Yes. All listed substitute parts use the TO-252-3 (DPAK) package with identical pin configuration and land pattern, ensuring direct PCB compatibility without layout modifications.

Q: What is the advantage of LD1086DT18TR over AP1086D18G-13? A: LD1086DT18TR offers extended input voltage range (30V vs. 12V), wider operating temperature range (-40°C to 125°C vs. 0°C to 125°C), and superior PSRR (82dB vs. 60dB), while maintaining identical 1.5A output current and 1.8V fixed output.

Q: Can LD1117ADT18TR be used if the application requires 1.5A output? A: LD1117ADT18TR provides only 1A output current, which is insufficient for applications requiring the full 1.5A capability of AP1086D18G-13. Use this part only in designs with maximum current requirements of 1A or less.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are RoHS3 compliant and maintain identical compliance certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

Q: What is the difference between tape & reel and bulk packaging? A: Tape & reel packaging is suitable for automated assembly processes, while bulk packaging is typically used for manual assembly or lower-volume applications. Electrical performance is identical; packaging format affects handling and assembly methodology only.
