For organisations reliant on older or obsolete components, RoHS conversion enables them to achieve RoHS Compliance.

What Is RoHS?

The RoHS Directive, adopted by the European Union, restricts the use of specific hazardous materials found in electrical products and electronic components. Substances such as lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), and certain brominated flame retardants are all subject to strict limits under the directive. RoHS compliance is mandatory for manufacturers who wish to market their products in the EU and other regions that have adopted similar standards. The directive applies to the UK post Brexit.  The RoHS regulations are enforced (excluding Northern Ireland) under the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012.

The Challenge of RoHS for Obsolete Electronic Components

Obsolete and hard-to-find components are often vital to maintaining legacy systems or fulfilling long-standing manufacturing requirements. However, many of these components were produced before RoHS standards were established and may contain restricted substances. This creates a dilemma for businesses: replace a component with a modern equivalent—often requiring redesign and requalification—or find a way to make the existing component compliant. The solution is RoHS Component Conversion. Component conversion provides a practical and cost-effective pathway to RoHS compliance, while still using the obsolete parts.  It typically involves:

  • De-soldering and removing non-compliant finishes (e.g., tin-lead solder)
  • Applying RoHS-compliant finishes, such as pure tin, nickel-palladium-gold, or other lead-free alloys
  • Thorough cleaning and preparation to ensure compatibility and reliability
  • Inspection and testing, including solderability and x-ray analysis, to confirm the success of the conversion

The Benefits of RoHS Conversion

As well as regulatory compliance, the benefits of RoHS conversion include:

  • Cost savings: avoiding the need to re-engineer products or redesign circuit boards to replace old components with new, which may require recertification of the system
  • Extended life for legacy systems: legacy systems can be kept operational longer by making the parts required for repair and maintenance viable for modern use.
  • Environmental responsibility: obsolete components can be used, rather than having to be thrown away.

Our Role

As well as years of experience in sourcing obsolete electronic components we also have years of experience of RoHS Conversion. Our processes follow the highest industry standards to ensure that your components meet both functional and regulatory requirements.
