Replacement verdict
Compatible functional replacement candidate
The AP4313KTR-G1 and AP4313KTR-E1 are functionally equivalent shunt voltage references sharing the same core electrical specifications, package, and pinout, with differences limited to manufacturer packing and ordering conventions. The AP4313KTR-E1 can serve as a functional replacement candidate for the AP4313KTR-G1, subject to validation of the specific ordering and packaging requirements for the target application.

Key electrical and mechanical differences between the two devices
| Parameter | AP4313KTR-G1 | AP4313KTR-E1 | Why it matters |
|---|---|---|---|
| Manufacturer | Diodes Incorporated | Diodes Incorporated | Same manufacturer ensures consistent design, documentation, and quality processes. |
| Function / Device Type | Constant voltage and constant current (CV/CC) controller | Constant voltage and constant current (CV/CC) controller | Identical device function is the primary requirement for functional substitutability. |
| Package / Case | SOT-23-6 | SOT-23-6 | Same package footprint allows drop-in replacement on an existing PCB. |
| Mounting Type | Surface Mount | Surface Mount | Matching mounting style is required for assembly compatibility. |
| Reference Voltage | 1.21 V (typical) | 1.21 V (typical) | The internal reference sets the regulated output; identical values preserve output accuracy and setpoint. |
| Supply Voltage Range | 2.5 V to 36 V | 2.5 V to 36 V | Same operating range ensures the part works across the same application conditions. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings confirm suitability for the same environmental conditions. |
| Packaging / Ordering Suffix | Tape and Reel (G1 suffix) | Tape and Reel (E1 suffix) | Both are supplied in tape and reel; the suffix difference reflects manufacturer ordering/packaging code rather than electrical differences. |

Frequently asked questions
What are the AP4313KTR-G1 and AP4313KTR-E1?
Both are adjustable precision shunt regulators from Diodes Incorporated in the AP4313 family, supplied in the SOT-23-3 package. They function as programmable voltage references for power supplies, chargers, and voltage monitoring circuits.
What is the difference between the -G1 and -E1 ordering suffixes?
The suffixes denote the manufacturer's packing and ordering designation rather than a change in electrical function. The -G1 and -E1 variants share the same base part number (AP4313KTR) and are differentiated by tape-and-reel packing quantity and labeling per Diodes Incorporated's ordering information. Designers should confirm the exact suffix definition in the current datasheet before release.
Are the AP4313KTR-G1 and AP4313KTR-E1 electrically interchangeable?
Because both carry the same base part number AP4313KTR, they share the same electrical specification and package. The suffix difference relates to ordering and packing, so they are functionally interchangeable provided the correct suffix is used for the intended production and inventory system.
What package do these devices use and how many pins?
Both parts are supplied in the SOT-23-3 surface-mount package with three pins: reference, cathode, and anode. The compact package suits space-constrained power supply and adapter designs.
What is the reference voltage and tolerance of the AP4313?
The AP4313 is an adjustable shunt reference with a nominal reference voltage of 2.5 V and a typical initial tolerance grade of 0.5% or 1% depending on the ordering option. The exact tolerance grade for a given suffix should be verified against the Diodes Incorporated datasheet.
Can the AP4313KTR-G1 and AP4313KTR-E1 be used as a direct drop-in replacement for each other?
Yes, since both share the same base part number, package, and electrical specification, they can be treated as drop-in equivalents. The only consideration is matching the correct ordering suffix to the customer's approved vendor list and reel quantity requirements.
What are typical applications for the AP4313 shunt regulator?
Typical uses include secondary-side voltage regulation in AC-DC adapters and chargers, programmable voltage references, overvoltage protection circuits, and precision current limiting. The adjustable 2.5 V reference supports a wide range of output settings via an external resistor divider.
