The Economy Power 2.5 (EP 2.5) connector system is a compact, 2.5mm pitch crimp connector solution designed for densely packed printed circuit boards. This guide provides the necessary specifications and selection tables to identify the correct components for your application, including housings, headers, and terminals.
Product Overview
The EP 2.5 series is designed for household appliances, HVAC, and industrial machinery. Key features include:
- Compact Design: 2.5mm centerline pitch.
- Asymmetrical Terminals: Designed to be loaded into the housing cavity only one way, ensuring correct orientation.
- Locking Mechanism: Features housing locking latches and polarization tabs.
- Material Options: Available in standard UL 94 V-0 rated Nylon or Glow Wire compliant materials.
Technical Specifications
Ensure your application requirements align with the following ratings:
- Voltage Rating: 250VAC.
- Current Rating: 4.2A maximum (single row).
- Operating Temperature: -55°C to 105°C.
- Wire Size: 0.13 to 0.56mm² (26 to 20 AWG).
- Pitch: 2.5mm (0.098").
Component Selection
The manual provides detailed selection tables for various configurations:
- Housings: Available in single and dual row configurations. Single row supports 2 to 15 positions (wire-to-wire) or 2 to 20 positions (wire-to-board). Dual row supports 8 to 40 positions.
- Headers: Available in vertical and right-angle configurations, with or without bosses.
- TPA (Terminal Position Assurance): Ergonomic and standard locking plates are available to secure terminals.
Terminals and Tooling
Terminals are made of plated copper alloy and are available in Standard Insertion Force or Low Insertion Force (LIF) variants. LIF sockets reduce insertion force by approximately 60% compared to standard sockets.
For assembly, TE Connectivity offers OCEAN applicators for automatic and semi-automatic applications. For low-volume production and prototyping, a hand tool is available for crimping contacts to wire.
Practical help
Common problems
Terminal insertion difficulty
Terminals are asymmetrical and must be loaded into the housing cavity in the correct orientation. Ensure the terminal is aligned properly before insertion.
Mating issues with competitive headers
Some 2-position plugs (e.g., 2301559-2) feature modified latches specifically designed to mate with competitive headers or specific TE headers with narrow latches.
Before use
- Verify the required wire gauge (26-20 AWG).
- Determine the required position count (2-15 for single row, 8-40 for dual row).
- Confirm if the application requires Glow Wire compliance (IEC/EN 60335-1).
- Select the appropriate terminal type (Standard vs. Low Insertion Force).
- Check if a vertical or right-angle header is required for your PCB layout.
Specs in practice
- Voltage Rating
- The maximum operating voltage is 250VAC.
- Current Rating
- The maximum current capacity is 4.2A for single-row configurations.
Images and diagrams
- The manual contains selection tables organized by housing style (Plug, Receptacle, Header, TPA) and row configuration (Single/Dual).
- Tables list part numbers based on the number of positions and flammability rating.
Model compatibility
- EP 2.5 connectors are intermateable with similar products available in the market.
- Specific part numbers (e.g., 2299683-1) feature narrow latches for compatibility with competitive manufacturer plugs.
