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:

PBB (Polybrominated Biphenyls)0.1%
PBDE ( Polybrominated Diphenyl Ethers)0.1%
Hexavalent Chromium0.1%
DEHP (Bis (2-Ethylhexl) phthalate)0.1%
BBP (Benzyl butyl phthalate)0.1%
DBP (Dibutyl phthalate)0.1%
DIBP (Diisobutyl phthalate)0.1%

Molex 2.5mm Nano-Fit Wire to Board Connector System

Power Connectors

Molex 2.5 mm Nano-Fit Wire to Board Crimp Receptacle Housings

Nano-Fit Wire to Board power connector crimp housings with a 2.5 mm pitch designed to provide full contact isolation. The compact package and tight pitch of these receptacles combined with optimum current density offer increased design flexibility for engineers in a wide range of applications. These Nano-Fit crimp housings are designed to provide full electrical isolation between the crimp terminals and to prevent arcing. Full isolation also prevents damage to the contacts during handling and mating and reduces the risk of shorting due to debris. These Nano-Fit crimp housings feature positive locking latches with an anti-snag design which prevents accidental disengagement and protects against damage caused by wire snags. The positive locking feature of these Nano-Fit power connector housings also prevents accidental mismating caused by shock, vibration or excessive cable strain. An audible click is produced to confirm mating completion. Tactile feedback is also provided when mis-mating is attempted. Polarization and keying aid accurate mating and prevent misalignment therefore reducing the errors that can be caused due to improper installation.
These Nano-Fit crimp housings are designed to be used with TPA (Terminal Position Assurance) retainerswhich are available separately (see stock number 122-4858 typically)
Crimp receptacles must be purchased separately (see stock numbers 122-4835 and 122-4836)
