The Hirose GT5-1S-HU is a single-position housing from the GT5 series, designed to accept F-series crimp terminals. This is a wire-to-board or wire-to-wire interconnect housing — it holds one terminal in a gray PBT body, ready for field assembly or harness production.
No direct form-fit-function replacement is documented in the available records. For existing designs, the last-time-buy window has closed; sourcing now depends on surplus or broker inventory. We can quote against an RFQ for whatever stock remains in the independent channel.
The housing body is molded in gray Polybutylene Terephthalate (PBT), a material with good electrical insulation and moderate chemical resistance. The single-position format suits point-to-point connections or service loops where a multi-circuit housing would be oversized.
