AP2114DA-1.2TRG1 Equivalent & Substitute Parts

Part Overview

The AP2114DA-1.2TRG1 is a linear voltage regulator IC from Diodes Incorporated designed for positive fixed 1.2V output at 1A current capacity in a TO-252-3 surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The AP7361C series provides direct parametric equivalents with improved performance characteristics while maintaining electrical and mechanical compatibility.

Key Parameters

Output Current	1A
Input Voltage (Max)	6V
Dropout Voltage (Max)	1.3V @ 1A
Quiescent Current	75 µA
Operating Temperature Range	-40°C ~ 85°C
Package Type	TO-252-3 (DPAK)
Protection Features	Over Current, Over Temperature

Substitute Part Grouping Explanation

Substitution eligibility for the AP2114DA-1.2TRG1 is determined by the following critical parameters:

Fixed output voltage of 1.2V
Output current rating of 1A minimum
Maximum input voltage of 6V or greater
TO-252-3 package compatibility
Operating temperature range of -40°C ~ 85°C or wider
Over current and over temperature protection

The AP7361C-12D-13 and AP7361C-12DR-13 meet all substitution criteria. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications for the parameters listed above. The primary differences are packaging format (standard tape & reel versus reel format) and improved dropout voltage performance (0.7V vs. 1.3V).

Engineering Selection Recommendations

Both AP7361C-12D-13 and AP7361C-12DR-13 are active production parts from Diodes Incorporated and are recommended as direct replacements for the obsolete AP2114DA-1.2TRG1. Both substitute parts maintain full compliance with ROHS3 and REACH requirements, matching the original part's environmental certifications.

The AP7361C series offers improved dropout voltage performance (0.7V versus 1.3V at 1A), which reduces power dissipation and improves efficiency in applications with tight input-to-output voltage margins. The quiescent current increase of 5 µA is negligible for most applications.

Selection between AP7361C-12D-13 and AP7361C-12DR-13 depends on procurement and assembly requirements. Both parts are electrically identical; the difference is packaging format (standard tape & reel versus reel format). Verify your assembly equipment compatibility with the selected packaging variant.

Frequently Asked Questions (FAQ)

Q: Can AP7361C-12D-13 and AP7361C-12DR-13 be used interchangeably with AP2114DA-1.2TRG1?

A: Yes. Both substitute parts meet all electrical and mechanical compatibility requirements. They share identical output voltage, current rating, input voltage range, operating temperature, and package type. Pin configuration and PCB footprint are compatible.

Q: What is the difference between AP7361C-12D-13 and AP7361C-12DR-13?

A: The parts are electrically identical. The difference is packaging format: AP7361C-12D-13 uses standard tape & reel packaging, while AP7361C-12DR-13 uses reel format. Select based on your assembly line equipment and procurement preferences.

Q: Why is the dropout voltage lower on the AP7361C series?

A: The AP7361C series represents an improved design iteration. The 0.7V dropout voltage (versus 1.3V on the AP2114DA) is a design enhancement that reduces power dissipation. This is a beneficial improvement for most applications.

Q: Are there any thermal or reliability differences between these parts?

A: Both parts share the same operating temperature range (-40°C ~ 85°C), protection features (over current and over temperature), and MSL rating (1 - Unlimited). No thermal or reliability trade-offs exist.

Q: What certifications do the substitute parts carry?

A: Both AP7361C-12D-13 and AP7361C-12DR-13 are ROHS3 compliant and REACH unaffected, matching the original AP2114DA-1.2TRG1 certifications.

Q: Is PCB layout modification required when switching to AP7361C parts?

A: No. Both substitute parts use the same TO-252-3 (DPAK) package with identical pin configuration and footprint. No PCB redesign is necessary.
