FAKRA, HSD or LVDS: Which Connection Do You Need?
You need to replace an automotive connector or connect two components, but the listings mention FAKRA, HSD and LVDS. The housings look similar enough to make a quick purchase tempting. Yet a familiar color or a matching vehicle brand does not establish that the connector, wiring and electrical requirements match your installation.
The buying question is simple: which connection do you actually need? Start by identifying both mating interfaces, then check the contact arrangement and the requirements of the connected equipment. The products discussed here do not specify exact vehicle, model-year or head-unit fitment, so those details need confirmation before ordering.

The one-minute explanation
FAKRA identifies a coaxial connector interface. Typical applications include GPS telematics, navigation and radio antenna connections. Its mechanical and color coding helps identify the required mating interface. That makes connector family and coding useful starting points when checking an antenna-related connection, but the application alone does not identify the exact part.
HSD identifies a shielded interconnect system built around shielded twisted-quad cable. HSD housings use mechanical and color coding, including a neutral coding option. Buyers need to confirm the required key and mating connector rather than choose a housing simply because its color looks familiar.
LVDS is a differential serial signaling standard, not a connector type. A listing can therefore describe an LVDS cable and also specify HSD connectors at its ends. Those descriptions answer different questions: one concerns signaling, while the other identifies the physical connection. The connector alone does not establish protocol compatibility.
For a purchase, turn those names into a specific description of each end: connector family, code, gender and contact arrangement. Then confirm the wiring and device requirements against the relevant drawings or specifications.
Compare the terms before choosing a product
| Term or listing | What it tells you | What still needs checking |
|---|---|---|
| FAKRA | A coaxial interface used in applications including navigation and radio antenna connections. | The exact connector family, coding, gender, mounting arrangement and device compatibility. |
| HSD | A shielded interconnect system with coded housings. | The mating key, contact assignment and applicable board or cable requirements. |
| LVDS | A differential serial signaling standard. | The actual connectors, wiring and electrical requirements of both components. |
| 4+2-pin HSD male connector listing | A connector product with a specified contact arrangement and selectable housing colors. | The exact housing code, mating connector, contact drawing and PCB footprint. |
| 4-pin HSD Z female-to-female cable listing | A complete cable assembly with specified connectors at both ends. | Both mating ports, contact assignment, routing length and final-system compatibility. |
The FAKRA adapter collection includes FAKRA and HSD connector products, including board connectors, splitter assemblies and HSD options. Treat the collection as a place to find candidates. Confirm the individual product configuration before selecting one; similar automotive housings are not automatically interchangeable.
Check the two HSD options against your installation
The 4+2-pin HSD male connectors are supplied as two connectors in the selected color option. The available labels are Cream White, Water Blue and Glaret Violet. Selecting an option determines the supplied configuration; the package is not a mixed-color kit.
The general HSD 4+2 arrangement adds two power contacts to four data contacts. That explains the arrangement's name, but it does not provide a numbered wiring map for this particular product. The listing requires confirmation of the pin arrangement, mating connector and board layout, and it does not specify the termination method.
The connector body has metal shielding, a keyed plastic housing and visible through-hole style contact tails. Before choosing it for a board repair or assembly, request the contact and assembly drawing and compare the PCB footprint. A matching product name is not enough to settle those details.
The HSD Z female-to-female LVDS cable is a complete assembly with four-pin HSD Z female connectors at both ends. Its listed length is approximately 80 cm. The page describes a black four-core cable, teal connector housings with secondary locks, and straight connector orientation at both ends.
Check whether that length and connector orientation suit your installation, as well as whether each end matches its intended port. The page specifically requires matching the key, pin layout and electrical requirements. It also calls for testing the cable in the final system before permanent installation.
Use specifications to confirm contact assignments
Neither supplied product page contains a numbered pinout. You therefore cannot use these listings alone to assign an individual contact to a signal or power connection. The general explanation of 4+2 contacts does not replace the product-specific specification.
- Record both interfaces. Photograph the mating faces and housings, and note any visible codes or markings.
- Identify the required product form. Establish whether you need a connector for a board or a complete cable assembly.
- Request the product specification or drawing. Ask for contact numbering, contact assignments and the applicable mating and assembly details.
- Compare with the equipment requirements. Confirm the wiring and electrical requirements at both connected components before installation.
The operating band is not specified for either HSD listing. Buyers who need guaranteed performance values should request the drawing or test data. Keep any unconfirmed requirement open until the relevant documentation answers it.
Common mistakes when ordering
- Buying by housing color alone. Color is part of connector identification, but you still need the correct family, key, gender and contact arrangement. Confirm the required code.
- Treating LVDS as a complete connector description. The signaling name does not identify the physical interfaces at both ends. Check the connector details separately.
- Assuming four-pin and 4+2-pin listings are equivalent. These pages describe different contact arrangements. Compare the required mating interface and specification before choosing.
- Inferring wiring from a photograph. A photograph helps identify the housing and visible contacts; the missing contact assignments still require the product specification.
- Relying on a vehicle or screen name. Exact vehicle and head-unit fitment are not specified. Compare the original connector, keying and wiring.
- Skipping the installation check. The listings call for testing the assembled connection before production use or testing the cable before permanent installation.
A short pre-purchase checklist
- Identify the connector family, code and gender at both ends.
- Confirm the contact arrangement and obtain the product-specific pinout.
- Check the board footprint or the cable length and connector orientation.
- Confirm the selected variant and package contents.
- Resolve electrical requirements and plan the specified system test.
If you need help narrowing the options, email photos of both connectors to antennaman@yilianduo.com. Include the product reference you are considering, any visible housing codes and the connection you need to make.
