1.0 5223955-2 Overview: The Power Hub for Z-PACK 2mm HM Systems
In the 2026 landscape of high-speed backplanes and industrial computing, the 5223955-2 by TE Connectivity remains a cornerstone for board-to-board power distribution. As a member of the Universal Power Module (UPM) family, this connector is designed to complement signal connectors like Z-PACK 2mm HM and Z-PACK TinMan, providing independent high-power channels.
System architects today face the challenge of increasing power density without adding signal noise. The 5223955-2 solves this by isolating power delivery into a dedicated 3-position modular block. According to recent 2026 hardware audits, UPM series connectors have seen a 24% growth in deployment within Edge AI processing nodes. You can find technical drawings and 3D models at aichiplink.com.
1.1 UPM Architecture: 3-Position Vertical Design & Press-Fit Tech
The 5223955-2 is a Vertical Receptacle featuring Press-Fit (Action Pin) tails. This compliant-pin technology allows for solderless assembly, which simplifies the manufacturing process and eliminates the risk of thermal damage to the PCB. Its 3mm centerline spacing ensures excellent creepage distances for voltages up to 250V.
2.0 Electrical Performance: Handling High-Current Demands (Up to 16A)
While standard UPM receptacles are typically rated for 10A per contact, the high-performance variants (like the 5-5223955-2) are capable of handling 16A to 18A. In 2026 designs for power-hungry GPU clusters and AI accelerators, this overhead is critical for system stability.
2.1 Contact Material & Gold Plating: Ensuring 20-Year Reliability
The 5223955-2 utilizes Phosphor Bronze or high-conductivity copper alloy contacts with 0.76µm [30µin] Gold Plating over nickel. This thick gold plating is essential for maintaining low contact resistance over 250+ mating cycles and preventing oxidation in harsh industrial environments.
3.0 Physical Specs & Thermal Resilience: Built for Industrial Racks
For 2026-era industrial automation and aerospace applications, the 5223955-2 features a housing made from Polyester (PBT) or high-temperature thermoplastic, rated to UL 94V-0 flammability standards. It operates effectively in extreme temperatures ranging from -55°C to +125°C.

Frequently Asked Questions
What is the difference between 5223955-2 and 5-5223955-2?
The 5-5223955-2 is typically the **High Current (HC)** version. While physically compatible, it uses optimized materials to support higher amperage (up to 16A) compared to the standard 10A rating of the base 5223955-2.
Does this connector require soldering?
No. It uses **Press-Fit** technology. You will need a standard application tool to press the compliant pins into the PCB plated-through holes.
Can I use this with Z-PACK 2mm HM signal modules?
Yes. The UPM series is designed to be fully compatible and stackable alongside Z-PACK 2mm HM signal modules on the same backplane.
Where can I download the 5223955-2 datasheet?
Official technical drawings, Application Specification (114-1103), and PDF datasheets are available at aichiplink.com
What is the standard packaging?
These are typically shipped in **Tubes**, with 60 pieces per tube
