Legislation and Compliance
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".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

2.5mm Wire-to-Board Connector, JST XA Series
Please note- the colour of the picture displayed above is for reference only.
JST XA Series 2.5mm Shrouded PCB Header Connectors
XA series wire to board shrouded PCB header connectors with a 2.5mm pitch. These XA 2.5 mm shrouded headers have a locking ramp device that provides a secure connection to the mating connector. This locking device also helps to prevent disconnection during the assembly process and due to vibration. Insertion guides and polarization bosses are also incorporated into the housing design of these XA series PCB headers to facilitate easy insertion and accurate alignment on the PCB. The housings of these XA series PCB headers are made from glass filled PA66 nylon which is effective against solder cracking problems. The header pins are rounded in design and reflow treated providing a low insertion force.
Features and Benefits
• Locking device for secure connection
• Insertion guides for accurate and easy insertion
• Polarisation bosses for accurate alignment on PCB
• Solder crack preventive material
• Low insertion force
