10-Position, 3.50mm Pitch Plug – What It Does in the Assembly
The 1-1986725-0: This is a 10-position plug with female sockets, designed for free-hanging inline use. The mating flange locks the plug to the matching header, giving it vibration resistance in industrial environments. Termination is screwless – push-in spring clamps accept solid or ferruled stranded wire from 14 to 30 AWG (0.05–2 mm²). No tool needed beyond a screwdriver to depress the spring for release.
Lifecycle Status – Obsolete, Sourced per RFQ
TE Connectivity has marked this part obsolete. No official replacement part number is listed on the record.
This plug mates with a matching 10-position header on 3.50mm pitch – typically a TE or compatible terminal block header with a mating flange. The push-in spring termination accepts solid or ferruled stranded wire: strip length per the manufacturer's recommendation (usually 8–10 mm), insert until the spring grips, and pull-test to confirm. To release, depress the spring with a 2.5 mm screwdriver.
Sourcing Reality for an Obsolete Part
Because 1-1986725-0 is obsolete, standard distributor stock is depleted. If a pin-compatible alternative is needed, we can research TE's current 3.50mm pitch plug family (e.g., the Buchanan or Eurostyle series) based on your position count and termination preference.
