Automotive Cable

Automotive cables are single-core or multi-core insulated wires specifically engineered for the low-voltage electrical systems of road vehicles. Available through LCSC Electronics — a global distributor with over 600,000 in-stock SKUs from 3,000+ manufacturers — automotive-grade cables are built to withstand the harsh operating conditions inside modern vehicles, including temperature cycling, vibration, fluid exposure, and tight harness routing constraints. LCSC supplies both off-the-shelf automotive wire and fully custom cable assemblies tailored to OEM and Tier 1 specifications.

Key Attributes

  • Standards Compliance: Automotive cables sourced through LCSC conform to internationally recognized standards, most notably ISO 6722 for single-core road vehicle cables and DIN 72551 for conductor construction requirements.
  • Conductor: Manufactured from soft-annealed electrolytic copper (Cu-ETP1), available in both bare and tinned copper variants for enhanced corrosion resistance. Cross-sectional sizes range from 0.35 mm² to 25 mm², covering signal-level wiring through moderate power distribution.
  • Temperature Rating: The operating temperature range spans -40°C to +105°C, with high-specification variants rated up to 125°C or 150°C for engine-compartment proximity.
  • Certifications: All cables are RoHS and REACH compliant, with select grades carrying UL and CE certifications.

Features & Benefits:

  • Thin-wall PVC insulation: The reduced-insulation-thickness design of FLRY-B cables minimizes harness diameter and weight, enabling routing in compact vehicle platforms without sacrificing dielectric performance or abrasion resistance.
  • Flame-retardant construction: Insulation materials comply with ISO 6722 45° flammability tests for self-extinguishing behavior, reducing fire propagation risk in safety-critical automotive wiring systems.
  • Splash resistance: The PVC insulation is engineered to resist short-term splashes of common automotive fluids, including mineral oils, fuel, and hydraulic fluids, protecting the cable during routine operation in under-hood environments.
  • Cold flexibility: Cables retain mechanical integrity down to -40°C, making them suitable for interior cabin routing, or underbody applications when protected within corrugated conduits.
  • Quality traceability: IATF 16949 and ISO 9001:2015 quality traceability — Manufactured with full lot traceability and automated reporting, meeting OEM documentation requirements for Tier 1 supply chains.

Application Scenarios:

  • Body electronics and lighting: Interior illumination, daytime running lights, rear lamps, and door control modules rely on FLRY-B for its lightweight construction and flexibility in confined body cavities.
  • CAN, LIN, and FlexRay network wiring: Low-current signal cables route digital communication between ECUs, body control modules, and infotainment systems in automotive bus architectures.
  • Electric vehicle (EV) auxiliary systems: Cabin wiring, battery management auxiliaries, and thermal management controllers in EV platforms use lightweight FLRY-B variants for low-voltage distribution.
  • Instrument panel and dashboard circuits: Compact 0.35 mm² to 1.0 mm² cross-sections enable high-density routing behind instrument clusters and HVAC control panels.
  • Motorcycle and powersports wiring: The thin-wall design and vibration resistance of FLRY-B cables make them suitable for space-constrained two-wheel and three-wheel vehicle platforms.

Customization Options

LCSC offers custom cable assembly and wire harness manufacturing with no minimum order quantity and lead times as short as 5–7 business days from its own production lines.

  • OEM color coding and striping: Insulation colors are available as solid or single-stripe variants across standard automotive color codes, enabling direct substitution in existing harness designs.
  • Custom lengths and bundling: Individual cables can be cut to specified lengths or bundled into multi-core sheathed harnesses with a common outer PVC jacket (FLRYY configuration) for organized routing.
  • Connector termination: LCSC's cable assembly service supports termination with connectors from major brands including JST, Molex, TE Connectivity, Amphenol, and Asian alternatives such as CJT and XKB, drawing from an inventory of over 860,000 connector SKUs.
  • Tinned copper conductors: Available as an upgrade over bare copper for applications requiring enhanced resistance to oxidation in high-humidity or salt-spray environments.

Frequently Asked Questions

1. What automotive cable standards does LCSC stock, and are they ISO 6722 compliant?

LCSC stocks automotive cables conforming to ISO 6722 (the international standard for single-core road vehicle cables) and DIN 72551. The primary types available are FLRY-A and FLRY-B for single-core applications and FLRYY for multi-core bundled harnesses. All stocked cables are also RoHS and REACH compliant.

2. What is the maximum operating temperature for LCSC automotive cables, and are higher-rated options available?

Standard FLRY-B cables are rated to 105°C continuous operation with a minimum of -40°C. Variants with Class C insulation operate at 125°C, while Class D variants are rated for 150°C, suitable for engine-bay proximity and turbocharger wiring. Short-circuit temperature tolerance is typically 160°C.

3. Can LCSC supply pre-terminated automotive cables with specific connector types?

Yes. Through its custom cable assembly service, LCSC can terminate automotive wire in connectors from JST, Molex, TE Connectivity, Amphenol, and Asian-brand alternatives from CJT and XKB. Connector inventory exceeds 860,000 SKUs. Contact cable@lcsc.com with pinout and mating connector details.

4. What cross-section sizes are available for CAN bus and LIN bus signal wiring?

Signal wiring for CAN and LIN networks typically utilizes 0.35 mm² to 0.75 mm² cross-sections, commonly using FLRY-B (reduced wall thickness PVC insulated) automotive cable. These sizes are optimized to provide reliable conductivity for low-current digital signals while minimizing the overall weight and bulk of the wiring harness.

5. Is there a minimum order quantity for custom automotive cable assemblies from LCSC?

No. LCSC's custom cable assembly service accepts orders with a minimum quantity of one piece, allowing engineers to validate a design with a single sample before committing to a production run. Standard lead time is 5–7 business days using LCSC's own production lines.

6. Are LCSC automotive cables suitable for use in electric vehicle (EV) platforms?

FLRY-B cables are used in EV cabin wiring, battery management unit auxiliaries, and thermal management circuit routing. For high-voltage EV powertrain applications (traction battery, inverter, motor), separate HV-rated cables complying with standards such as ISO 6469 or LV 216 are required.
