Product context

Product description and application

Erich Jaeger 311304 is Adapter / Voltage Reducer 24V > 12V - - Connects 15P/24V socket (ISO 12098) on vehicle side with 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 12098 points to the 15-pole 24V truck-trailer connection family; it is normally checked together with the matching 15-pole plug, socket or coil cable. The known selection frame is ISO 11446, ISO 12098, 12V, 13P and commercial vehicles, cars, agriculture.

What does 311304 do?

This page treats 311304 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: 141053 15P/24V Socket (ISO 12098 ADR), 221019 13P/12V Plug (ISO 11446), 541128 15P/24V supply cable - with15P/24V supplementary socket (ISO 12098) and 2x 8P connector, 641167 15P/24V Coil (ISO 12098 ADR), 121133 13P/12V Economy Socket (ISO 11446). 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 311304 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.
