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
TE Connectivity MTA-156 3.96mm Interconnect System
MTA-156 (Mass Termination Assembly) 3.96 mm pitch connector system for labour and cost saving mass termination of wires in wire-to-board and wire-to-wire applications. These MTA-156 connectors are based on IDC (insulation displacement contact) technology allowing one-step assembly and eliminating the need for wire stripping saving both time and cost. Using production hand tooling these MTA-156 IDC connectors can be quickly assembled to 26 AWG to 18 AWG discrete wire or ribbon cable. The MTA-156 connector system consists of female IDC connectors and PCB headers. The housings of the IDC connectors are colour coded according to wire size
TE Connectivity MTA-156 IDC Closed End Connector Assemblies
MTA-156 IDC closed end connector receptacle assemblies preloaded with IDC contacts on a 3.96mm centerline that accept stranded discrete wire sizes from 18 to 26 AWG. These MTA-156 IDC closed end connectors are end to end stackable, have white nylon 6/6 UL94V-2 housings with moulded ribs to prevent reverse mating and are available with locking ramps and polarization tabs. The IDC socket contacts of these MTA-156 IDC closed end receptacle connectors are matte tin plated with the exception of stock number 863-8369 which has 0.00038μm gold plated contacts.
Part numbers X-640431-X have accept an 18 AWG discrete wire size
