SSC crimp socket identity
The 184030-3 is a tin-plated socket member of TE Connectivity AMP Connectors' SSC series, accepting 14-20 AWG wire via crimp termination. The contact finish thickness is 31.5µin (0.80µm), and the part is available in Tape & Reel or Cut Tape packaging.
Gold vs tin selection
Within the SSC series the tin-plated 184030-3 stands alongside the gold-plated 184030-1 (30.0µin gold). Both accept the same 14-20 AWG wire and use the same crimp termination — the plating grade is the decision axis: tin for cost-sensitive, lower-cycle-count applications; gold for higher mating-durability or corrosive-environment duty.
