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.

Product Details
A cost effective range of connectors and accessories, with a choice of performance level, for use in industrial and commercial applications.
3M 3000 Series 2.54 x 2.54 mm Cable Mount IDC Socket Connectors
3000 series cable mount industry standard IDC ribbon cable socket connectors with a 2.54 x 2.54 mm pitch. These IDC cable sockets accept 26 AWG and 28 AWG solid and stranded 1.27 mm pitch flat ribbon cable or discrete wire. The use of IDC contacts eliminates the need for prior cable preparation and stripping and provides a quick and simple interconnection system for mass termination. The contacts are made from beryllium copper which has a high resistance to corrosion, good wear resistance and better electrical conductivity than brass or bronze. The housings of these 3000 series IDC sockets feature dual slot military polarization to aid accurate mating with the header connector. The design of these 3000 series IDC sockets sets the standard for MIL spec and IEC standardization. These 3000 series ribbon cable sockets feature positive locking metal 'J' clips that ensure the cover of the connector is securely retained. The covers have a transfer adhesive on them that holds the cover onto the ribbon cable for precise alignment between the connector and the cables. This feature also results helps with the production of high yield terminations. A pull tab is available separately which is attached to the socket using a strip of adhesive. The pull tab is used to reduce stress on the cable terminations when the socket connector is unplugged from the mated header. A keying plug is also available which is plugged into a socket contact so that the male pin cannot enter it.
PCB mounting components are based on a 2.54mm grid pitch
Cable mounting connectors use 1.27mm pitch flat ribbon cable
