Keep an Avaya IP Phone Ready for Daily Operation
When an Avaya desk phone needs a replacement external power source because the original adapter is missing, damaged, or no longer providing stable power, the PSAC12R-050 / Avaya P/N 700513357 provides the electrical specification used by compatible Avaya IP phone systems. This adapter delivers 5V DC at up to 2.4A, with a maximum rated output of 12W, and the 700513357 version is identified by Avaya as the EU-plug power adapter for the 1600 Series and J Series phones. The model is manufactured by Phihong Technology Co., Ltd. and belongs to the PSAC12R power adapter family. Its barrel output uses a 5.5 × 2.1mm connector with center-positive polarity, making connector matching an important part of the replacement check.
Application Scenarios
The PSAC12R-050 is intended for Avaya business telephone installations where an external low-voltage power source is required instead of relying solely on PoE or another network power solution.
- Avaya 1600 Series Phones: Provides external 5V power for compatible 1600 Series IP and business telephone installations.
- Avaya J Series Phones: Used as an optional AC/DC power source for compatible J139, J159, J169 and J179 IP phones.
- Phone Deployment and Maintenance: Useful when a desk phone's existing power adapter has been lost, damaged, or requires replacement.
- Expansion Module Installations: External 5V power may also be required for compatible J100 expansion-module configurations depending on the phone and installation setup.
Avaya documentation identifies PSAC12R-050 as the 5V DC power adapter for the J139, J159, J169, J179 and J189 families, while Avaya's material-code documentation identifies 700513357 specifically as the 5V 12W EU-plug version.

The PSAC12R-050 family is specified as a 12W, 5V wall-mount AC adapter with a 5.5 × 2.1mm barrel output and positive-center polarity. The exact Avaya material code determines the regional AC plug: 700513357 is the EU-plug version.
OEM Replacement Compatibility
This adapter can replace or correspond to the following Avaya power-supply identifiers:
- Avaya P/N 700513357
- Avaya PSAC12R-050
- Avaya 5V 12W Power Adapter for 1600 Series, EU Plug
The 700513357 material code is specifically documented by Avaya as the EU-plug 5V 12W power adapter, while the same PSAC12R-050 model is offered under different Avaya material codes for other regional plugs.
Compatible Devices
The documented device compatibility includes:
- Avaya 1600 Series IP Phones
- Avaya 1603 / 1603SW
- Avaya 1608 / 1608-I
- Avaya 1616 / 1616-I
- Avaya J139 IP Phone
- Avaya J159 IP Phone
- Avaya J169 IP Phone
- Avaya J179 IP Phone
The PSAC12R-050 is explicitly identified in Avaya documentation as the optional 5V DC adapter for the J139, J159, J169 and J179 families. Independent Avaya equipment references also identify 700513357 as the EU-plug version for the 1600 Series and J Series.
Replacement & Compatibility Check
For this adapter, the safest compatibility check is to match the Avaya P/N 700513357 or PSAC12R-050 first, then verify the electrical and physical specifications. The replacement should provide 5V DC, support up to 2.4A, use the 5.5 × 2.1mm barrel connector with center-positive polarity, and have the appropriate regional AC plug. A 5V adapter with a different barrel size or polarity should not be treated as interchangeable simply because its voltage is the same. The regional plug is particularly important. 700513357 is the EU-plug version; Avaya separately identifies 700512377 as the US version and 700513359 as the UK version.
