H05V-K vs H07V-K: EN 50525 Wire Selection Guide

H05V-K and H07V-K are harmonised European single-core PVC insulated wires. They share a 70 °C temperature rating, but they are not interchangeable when voltage, conductor size or certification scope changes.

Quick comparison

Item H05V-K H07V-K
Voltage rating 300/500 V 450/750 V
Temperature rating 70 °C 70 °C
Insulation PVC PVC
Conductor Flexible copper Flexible copper
VDE certificate scope 1 × 0.5–1.0 mm² 1 × 1.5–35 mm²

Voltage and size are the first checks

H05V-K is commonly selected for control, lighting and appliance wiring at 300/500 V. H07V-K is selected for higher-voltage and larger conductor applications at 450/750 V. Confirm both the voltage rating and the required conductor size because the VDE certificate scope is size-specific.

See the documented H05V-K construction data and the H07V-K construction data.

VDE certificate 40028605

The VDE Marks Approval No. 40028605 covers H05V-K 1 × 0.5–1.0 mm² and H07V-K 1 × 1.5–35 mm². The certificate references DIN EN 50525-2-31 (VDE 0285-525-2-31):2012-01 and was updated on 29 January 2024. Verify that the finished product uses a covered construction and that the marking and documentation match the order.

Selection checklist

  1. Confirm the required voltage level.
  2. Confirm the conductor size in mm².
  3. Check the required colour and marking.
  4. Check the minimum bending and routing requirements.
  5. Confirm the applicable certificate scope.
  6. Confirm cut length, packaging and destination.

FAQ

Can H05V-K replace H07V-K?

Only when the voltage rating, conductor size, certificate scope and application requirements are all satisfied. They are separate harmonised designs.

Does the VDE certificate cover all sizes?

The certificate lists the covered sizes. H05V-K is shown as 0.5–1.0 mm² and H07V-K as 1.5–35 mm².

Can Xinya supply the certificate package?

Questions & answers

Frequently asked questions

Certifications, lead time, payment, shipping and MOQ — the points buyers ask about most often. If something is still unclear, send us your requirement and we will answer directly. See the full FAQ →

01 Are you a manufacturer or a trading company?

We are a wire harness manufacturer — cutting, stripping, crimping, sealing and testing are all carried out in-house at our Suzhou plant. We are also an authorised distributor of Xinya brand electronic wire, so you can source both the wire and the finished harness from one supplier.

02 What certifications do your electronic wires have?

Our electronic wires carry UL, VDE, PSE and CE approvals, together with RoHS and REACH compliance for the European market; TUV approvals are available for PV and renewable-energy wire. Certificates and test reports are issued by the manufacturer and can be supplied with your quotation on request.

03 How long is the lead time?

For electronic wire, popular styles such as UL1007, UL1015, UL1061 and UL1569 are normally available quickly; other styles, non-standard colours and cut lengths usually take around 7 days. Wire harnesses are made to order, so the schedule depends on your drawing, connector availability and quantity — we confirm it in the quotation.

04 What are your payment terms?

We commonly accept T/T (telegraphic transfer), PayPal and Western Union. Typically a 30% deposit is required before production, with the balance paid before shipment.

05 How do you ship the goods?

Samples and small orders are shipped by international express (DHL, FedEx, UPS, TNT) or by air freight. Larger orders normally go by sea to reduce freight cost. We can quote EXW, FOB, CIF or door-to-door terms and will recommend the option that best fits your budget and delivery date.

06 Do you have a minimum order quantity (MOQ)?

We keep a low MOQ to support your business. Generally the MOQ is 1 piece for standard models, although it may vary slightly for customised products. Small trial orders are welcome.

07 Can you build harnesses to our own drawing or sample?

Yes. We build to print and build to sample — send us a 2D drawing, a BOM, connector part numbers or even a photo of the part in use, and we will assemble, test and quote accordingly.

08 Can I get a sample before placing a bulk order?

Yes. We are happy to build a prototype first so that you can approve the fit, crimp and finish before committing to volume. Send the drawing and the target quantity and we will quote sample cost and lead time.

09 What information do you need to give a quotation?

For wire: the style or UL number, AWG, voltage and temperature rating, insulation, conductor, colour and length. For harnesses: the drawing or BOM, connector brand and part number, terminal and housing type, wire specification, cut length and tolerance, sleeving or tubing, label and packaging requirements, quantity and destination. If anything is unclear we will ask — or propose a construction for you.

10 Do you support OEM / ODM and private labelling?

Yes. We work with customer-specified connectors and brands as well as JST, Molex and HongXing, and can add printed markers, custom labels, printed bags and your own carton artwork for OEM and ODM projects.

11 How do you control quality?

Every order goes through incoming wire inspection, cutting and stripping checks, crimp height and terminal pull-force testing, 100% continuity and open-and-short testing, and a final dimensional and visual inspection. Inspection records can be supplied with the shipment when your project requires them.

12 Can you help with wire and connector selection?

Yes — our engineers help match wire gauge, insulation and temperature rating to your current, voltage and working environment, and select a terminal and housing combination that crimps reliably. Describe the application or send a sample and we will propose a construction.

13 Can you supply cut lengths and custom packaging?

Yes. Wire can be supplied in cut lengths, coils or spools, with PE bags, cartons, pallets and printed labels arranged to suit your warehouse or production line.

14 Do you ship worldwide, and can I visit the factory?

We ship worldwide, with regular shipments to Europe, North America, South-East Asia, the Middle East and Australia. You are welcome to visit our plant in Suzhou, and you can see our production lines in the factory videos on this site.

15 What happens if there is a quality problem after delivery?

Contact us with the order or batch number and photos of the issue. We will check it against our production and inspection records and, where the fault is confirmed on our side, arrange replacement or credit.
