Molex 105431, 105430 And 105429 Nano-Fit SMT Connector

Power-application customers are faced with the decision of choosing between headers with exposed terminals, leaving connectors susceptible to damage, and large, fully-isolated headers that take up too much space. Compact Nano-Fit connectors provide design engineers fully protected header terminals in a small package. Another challenge that design engineers face is meeting the requirement to use multiple headers of the same circuit size on one PCB. This complicates the assembly due to possible mis-mating of a receptacle to the wrong header. Nano-Fit connectors offer different mechanical keying options, enabling customers to reduce the risk of cross mating while improving assembly speed with color-coding logic.



  • Smallest fully isolated headers in the market
    • Up to 69% smaller than competing connectors in the x axis
  • Optional TPA (terminal position assurance) retainer
    • Ensures terminals are fully seated in housing to reduce backout. Retains terminals if main retention feature fails
  • Ultra-low mate force terminal
    • Reduces operator fatigue. Improves assembly compliance for high-circuit applications
  • Positive-lock housing with anti-snag design
    • Ensures mated connector assemblies will not accidentally disengage. Provides audible click while mating. Protects latch from damage due to wire snags
  • Enables use of multi-layer boards by eliminating the need for through holes
    • Opens up real estate on space-constricted PCBs. Potentially reduces costs by enabling use of smaller PCBs with fewer drilled holes
  • Available in embossed tape for pick-and-place assembly
    • Enables quick and accurate component placement to meet fast time-to-market requirements
  • Multiple mechanical keying and color-coding options
    • Allow same-circuit, multiple connector use with virtually no chance of cross- mating. Enable faster assembly with visual indication of proper mating
  • Multiple mechanical keying and color-coded options
    • Allow same-circuit, multiple-connector use with virtually no chance of cross mating. Color coding enables faster assembly with visual indication of proper mating
  • Retention tang and contact rib
    • Maintains stable contact
  • Terminal interface with 4 points of contact
    • Offers redundant, secondary current paths for long-term performance and reliability
  • Fully isolated terminals
    • Protect against potential damage of terminals during handling and mating
  • Terminals available in gold and tin plating
    • Delivers different cost options while meeting performance needs
  • Short electrical path
    • Provide superior signal integrity performance
