5V DC adapter for Cisco SPA and Yealink SIP phones

This regulated 5V DC power supply carries CE and FCC approvals and is housed in a compact, flame-retardant enclosure. It replaces the original wall-wart for a wide range of Cisco SPA and Yealink SIP desk phones, providing a direct plug-in replacement for office and home deployments.

Interface and voltage constraints

The adapter delivers a fixed 5V DC output through a barrel connector matched to the listed phone models; it cannot power devices that require 12V, 24V or PoE injection. Polarity and tip dimensions are specific to the supported Cisco SPA and Yealink handsets, so it will not fit phones with different jack sizes or voltage needs.

Model compatibility decides fit

Compatibility is limited to the exact Cisco SPA models 300, 303, 500, 501, 502, 504, 508, 509, 512, 514, 525, 900, 922, 942, 962 and Yealink SIP-T series including 19, 20, 21, 22, 26, 27, 28, 41, 42, 46, 48, 54, 56, 58 plus Polycom VVX 150, 250, 350, 450. Buyers with any other phone model must verify the jack and voltage before purchase.

Questions about this item

Which Cisco SPA or Yealink SIP phone models does this 5 V adapter support?

It covers Cisco SPA models 300, 303, 500, 501, 502, 504, 508, 509, 512, 514, 525, 900, 922, 942 and 962, plus Yealink SIP-T20P, T22P, T26P, T27, T28P, T41P, T42G, T19P, T21, T21P, T54S, T56A, T58A, T58V, T46G and T48G.

What does the 5 V DC rating mean when the adapter is plugged into a desk phone?

The unit delivers a steady 5 V DC output that matches the input requirement of the listed Cisco and Yealink models, so the phone powers on and runs without an external brick.

What connector standard does the adapter use and what does it limit?

The adapter uses a standard barrel connector sized for the listed SPA and SIP phones; the 5 V DC output caps the maximum voltage the phone receives, preventing over-voltage damage.
