3-Position IDC Socket for Discrete Wire Harnesses
The Hirose DF1-3S-2.5R26(05) is a 3-position IDC socket from the DF1 series, designed for discrete wire termination in free-hanging (in-line) harness assemblies. It accepts 26 AWG wire and terminates via insulation displacement, eliminating the need for crimp tooling on individual contacts.
Last-Time-Buy Sourcing — Act Before Stock Clears
This part is on Last Buy status, meaning the manufacturer has scheduled end-of-production. Procurement should place final orders within the LTB window to secure inventory for ongoing builds. No official successor is listed; once stock is exhausted, a cross-reference to a functionally equivalent part will be needed.
The IDC termination style presses the 26 AWG conductor into a slotted contact beam, displacing insulation to make gas-tight connection. This suits high-volume harness production where a single press tool terminates all three positions simultaneously. The feed-through feature allows daisy-chaining wires through the connector body without cutting the continuous wire run.
Tin-Plated Contacts for Discrete Wire Duty
Tin contact finish is standard for IDC applications where mating cycles are limited and the operating environment is dry or indoor. The free-hanging mount and single-row layout make this socket a straightforward fit for point-to-point wiring in control panels, appliance harnesses, or low-voltage signal distribution where the 2.50mm pitch matches standard ribbon cable spacing.
