Substitute Part Grouping Explanation

Substitution of the obsolete 9-51863-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 51863-4 maintains identical specifications for wire gauge (18 AWG), terminal type (circular), stud configuration (6 stud), termination method (crimp), contact material and finish (copper with tin), insulation material (polyamide nylon), and all dimensional characteristics including thickness, width, length, and insulation diameter range.

The substitution is valid based on the following key parameters:

• Wire Gauge: 18 AWG (identical)
• Terminal Type: Circular (identical)
• Stud/Tab Size: 6 Stud (identical)
• Termination: Crimp (identical)
• Contact Material: Copper (identical)
• Contact Finish: Tin (identical)
• Insulation Material: Polyamide (PA), Nylon (identical)
• All dimensional specifications (identical)
• Insulation Restriction Feature (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
