The TE Connectivity 1-440129-1 is an 11-position, single-row receptacle housing from the High Performance Interconnect (HPI) series. It uses a 2.00 mm pitch — tight enough for a compact wire-to-board harness but wide enough to keep the crimp terminals manageable with standard tooling. The housing is natural thermoplastic, free-hanging (in-line), and accepts female socket contacts that are crimped separately. This is the wire-side half of the connection; it mates with a matching pin header (same pitch, same series) to complete the circuit.
Critical Procurement Detail: Contacts Are Sold Separately
The housing ships empty — the note on the line is "Contacts Not Included." You need to order the matching crimp terminals (female socket contacts for the HPI series) as a separate line item. The 2.00 mm pitch and single-row layout mean the terminal part number will be specific to this wire gauge range; check the HPI application tooling guide for the correct crimp die.
Mating Header and Fit Check
This receptacle mates with a 2.00 mm pitch HPI pin header, also single-row, 11 positions. The header will be a through-hole or surface-mount variant depending on your board design. The free-hanging housing latches onto the header — the locking ramp (if present on the header side) keeps the pair together under vibration. Confirm the header part number from the same HPI series; the pitch and position count are the hard constraints.
Sourcing and Availability
For BOM planning, factor in the separate terminal order and the lead time for the full assembly.
