RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".

Product Details
RS PRO Lead-Free Solder Wire
From teh trusted RS PRO brand, this lead-free solder wire from RS is a resin-based SAC305 solder wire. SAC305 is a specially-formulated lead-free alloy that contains 96.5% tin, 3% silver and 0.5% copper. SAC305 alloy comes under the JEIDA recommendation for lead-free solder, conforming to J-STD 006.
The solder wire flux is specifically formulated to wet common Printed Circuit Boards (PCB) and components. The residue left after soldering is completely clear and is safe to leave on the PCB post soldering.
Features and Benefits
• Multipurpose solder wire that can be used for a variety of soldering tasks
• Suitable for soldering all products that must be RoHS compliant
• Melting point between 217-219°C
• Flux content 3.3%
• Soldering tip typical temperature for use with this solder wire is 360-400°C
Applications
Solder is used alongside soldering irons, particularly in securing electrical components to integrated circuit boards. The solder melts easily when heated, and cools quickly, meaning it can be moulded to secure components in place in solder joints. The quick setting nature of solder means it can also be used for light brazing.
Because of its relatively low melting point, solder can be reworked easily by heating it to melting point and using a solder sucker to remove it.
Solder is commonly used with SMD and through-hole components, with applications in repair, prototyping and production.
What are the differences between lead-free solder and leaded solder?
Lead-free solder is generally regarded as having a more positive environmental impact than leaded solder, and also as being safer for human use. However, lead-free solder also has potential production advantages. Lead-free solder can offer better lead spacing, which makes it more suitable for high-density components where pitches are tight. This means potentially better performance where space saving is a concern.
The advantages of lead solder are that it has a lower melting point, which is sometimes preferable for hand working components. Also, lower working temperatures reduces the risk of damage to components and circuit board.
Unlike lead-free solder, lead solder does not have a shelf-life and is less prone to losing quality after prolonged exposure to oxygen. However, many electronic application requirements exclude the use of lead solder, due to the toxicity of lead.
