Substitute Part Grouping Explanation

Substitution of the obsolete 8-350820-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 3-350820-2 maintains identical specifications for tab width (0.250"), tab thickness (0.032"), wire gauge rating (14-16 AWG), insulation classification (fully insulated), contact material (brass), contact finish (tin), insulation diameter (0.160"), overall length (0.855"), and mounting configuration (free hanging in-line).

The primary distinction between these parts is product status and packaging configuration. The 8-350820-1 is obsolete with limited inventory, while the 3-350820-2 is active with significantly higher stock availability. Both parts share the same base product number (350820) and series designation (Ultra-Fast), confirming functional equivalence.
