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
Digital Potentiometer - Microchip
MCP414x/416x/424x/426x Digital Potentiometers
The Microchip MCP413x, MCP415x, MCP423x and MCP425x range of devices are Digital Potentiometers with a SPI interface and EEPROM memory.
Featured is WiperLock Technology, providing a method of ’locking’ the wiper configuration. To unlock a high-voltage command is required (>8.5 V), protecting the setting during normal operation.
7-bit (129 steps) and 8-bit (257 steps) versions are available in various RAB resistance options from 5 kΩ to 100 kΩ. Further variants also give the choice between Rheostat and Potentiometer pinouts, Single and Dual Resistor Network options are also available.
Features
Zero Scale to Full-Scale Wiper Operation
Low Wiper Resistance: 75 Ω (typical)
Low Temperature Coefficient: Absolute (Rheostat) 50 ppm, Ratiometric (Potentiometer) 15 ppm (typical)
Automatic Recall of Saved Wiper Setting
WiperLock Technology
SPI Serial Interface
Resistor Network Terminal Disconnect Feature
Brown-Out Reset Protection: 1.5 V (typical)
Serial Interface Inactive Current: 2.5 μA (typical)
High-Voltage Tolerant Digital Inputs: Up to 12.5 V
Supports Split Rail Applications
Internal Weak Pull-Up on all Digital Inputs
Wide Operating Voltage: 1.8 V to 5.5 V
Wide Bandwidth (-3 dB) Operation: 2 MHz for 5.0 kΩ device (typical)
Model Variants
Potentiometer Wiper Configuration: MCP4141, MCP4161, MCP4241, MCP4261
