Product context

Product description and application

Erich Jaeger 311308 is Adapter / Voltage Reducer 24V > 12V - - connects 7P/24V socket (ISO 1724 - connected with 24V) on vehicle side to 13P/12V plug (ISO 11446) on trailer side. This adapter connects two connector standards or layouts. It is especially important to verify the pin allocation, because the mechanical fit alone does not prove that every lighting and auxiliary function is routed correctly. ISO 11446, ISO 1724 - Type N and 12V should be verified against the vehicle or trailer wiring diagram. The known selection frame is ISO 11446, ISO 1724 - Type N, 12V, 7P and commercial vehicles, cars, agriculture.

What does 311308 do?

This page treats 311308 as a real vehicle-electrical component, not just as a search term. In practice the part is selected by connector family, electrical standard, voltage, pole count and the way it is mounted or connected in the vehicle. For a adapter, the mating component and cable route are part of the decision.

Technical checks before replacing it

Check the product drawing, connector layout, mounting position, electrical load and mating component before treating another part as equivalent.

How ConnectorRoute approaches the alternative

ConnectorRoute starts with the Erich Jaeger number, then checks the application: vehicle type, yearly volume, existing mating connector, drawings or photos, required approval level and supply continuity. Only after that does an alternative become a quoteable route instead of a guess.

Products that belong in the same request

For a useful quote, include related system parts where possible: 121133 13P/12V Economy Socket (ISO 11446), 201212 7P/12V Plug (ISO 1724 - Type N), 701015 7P/12V Cable (ISO 1724 - Type N) - with 7P/12V plug (ISO 1724) and 7P/12V coupler (ISO 1724), 621004 13P/12V Coil (ISO 11446), 101100 7P/12V Socket (ISO 1724 - Type N). That helps prevent solving one article number while leaving the matching plug, socket, coil cable, adapter or supply cable as the next bottleneck.

Questions about this reference

Can Erich Jaeger 311308 be replaced one-to-one?

Sometimes, but it should not be assumed from the article number alone. The connector standard, pole count, voltage, contact type, seal, cable entry and application need to match before ConnectorRoute confirms a replacement.

What should I send with an enquiry?

Send the Erich Jaeger article number, quantities, yearly demand, photos of the installed part, drawings if available, the mating connector and any vehicle or trailer information.

Why does the page mention related products?

Truck and trailer electrics are system-based. A socket, plug, coil cable, adapter and supply cable often need to be checked together to avoid a partial replacement route.
