What is the difference between Metripack 150 and 280?

The Metri-Pack 150 and Metri-Pack 280 connectors are both part of Aptiv’s modular electrical connector family, but they’re designed for different current capacities and applications. Here's a breakdown to help you compare:

Physical & Environmental Features

Size & Density:

150 Series is smaller and more compact, ideal for tight spaces and high-density applications.

280 Series is larger, better suited for higher power needs.

Sealing Options:

Both series offer sealed and unsealed versions.

Sealed connectors include interfacial and wire seals for protection against moisture, dust, and chemicals.

Durability:

Both are built to withstand vibration, temperature extremes, and harsh environments.

280 Series is often used in more demanding power applications like motors and power accessories.

Common Applications

Metri-Pack 150 Series:

Sensors

Lighting circuits

Body electronics

Climate control systems

Metri-Pack 280 Series:

Power distribution

Motors and actuators

Fuse panels

Heavy-duty vehicle systems

What is the difference between Weather pack and Metripack?

Both Weather-Pack and Metri-Pack connectors are designed by Delphi (now Aptiv) and are widely used in automotive and industrial applications—but they serve slightly different purposes depending on your needs. Here's a breakdown:

Environmental Protection

Weather Pack is built for harsh environments—think engine bays, marine, and off-road use. It’s highly resistant to moisture, chemicals, and temperature extremes.

Metri-Pack sealed versions also offer strong environmental protection, but the unsealed versions are better suited for interior or protected areas.

Application Use

Weather Pack:

Exterior lighting

Engine sensors

Marine and agricultural equipment

Metri-Pack:

Power distribution

Fuse panels

Body electronics

High-current systems

Ease of Use

Weather Pack is simpler to assemble and maintain, with fewer components and a more uniform design.

Metri-Pack offers more modularity and higher current options, but requires more specific tooling and parts.

They are not interchangeable due to differences in terminal shape, locking mechanisms, and housing design.

How to de-pin delphi metri-pack 150?

Depinning a Metri-Pack 180 connector requires precision and the right tools to avoid damaging the terminals or housing. Here's a step-by-step guide to help you do it like a pro:

What You’ll Need

Metri-Pack terminal removal tool (or a small pick tool)

Needle-nose pliers (optional)

Good lighting and a steady hand

Step-by-Step Depinning Process

Identify the locking mechanism Metri-Pack 180 connectors typically have a TPA (Terminal Position Assurance) lock. Slide or lift this out gently to access the terminals.

Insert the removal tool Use a proper Metri-Pack removal tool to press down the locking tab inside the connector.

Release the terminal tab Gently push the tool in until you feel the tab disengage.

Pull the wire out Once the tab is released, carefully pull the wire from the back of the connector.

Inspect and rework if needed Check the terminal for damage. If you're reusing it, make sure the locking tab is still intact. Otherwise, crimp a new terminal.

What size are Delphi connectors?

Aptiv (formerly Delphi) connectors come in a variety of sizes depending on the series and application. See Aptiv connectors at Waytek.
