The TE Connectivity AMP-Latch 1-1658526-3 is a 20-position, dual-row IDC receptacle designed for mass-termination to 28-30 AWG ribbon cable. The blue housing includes a polarizing key and integral strain relief, which keeps the termination point from flexing during cable dress.
IDC Termination — No Crimp, No Solder
This is a mass-termination IDC connector: the ribbon cable is pressed into the insulation-displacement slots in one operation using a hand or pneumatic press. The 28-30 AWG range covers the common 0.025"-pitch ribbon cable stock used for parallel data buses and GPIO headers. The free-hanging (in-line) mounting means the receptacle floats on the cable — no board lock, no panel cutout — so the assembly is routed to wherever the header sits on the PCB.
No end-of-life notice or last-time-buy window is on record. No official second-source or cross-reference exists; the only direct equivalent is the same AMP-Latch receptacle in the matching position count.
