DF3AA-4EP-2C from Hirose Electric Co Ltd is a 4-position rectangular connector housing in the DF3 series, designed for compact wire-to-board and panel-mounted interconnect applications. With a 2.00 mm pitch, male pin configuration, crimp termination style, and panel-mount snap-in installation, it fits equipment where secure mechanical retention and serviceable cable assembly are important. Typical use cases include industrial controls, compact electronic assemblies, instrumentation, and general-purpose embedded hardware. The supplied data indicates a wide operating range of -55°C to 105°C, supporting use in demanding environments. This part is listed as contacts not included, so designers should confirm compatible crimp contacts during BOM development. Lifecycle status is currently unknown, which means procurement teams should verify current manufacturer availability before locking it into long-term production. RoHS compliance information is not available in the provided specifications, so engineers should obtain the latest compliance declaration or datasheet confirmation from Hirose before release for regulated markets.
