Substitute Part Grouping Explanation

Substitution of the 641218-3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for connector type, contact configuration, position count, pitch, mounting method, termination technology, wire gauge compatibility, and contact finish properties. The primary distinction between the main part and its substitute is product status and packaging configuration. The substitute part 3-641218-3 maintains complete electrical and mechanical compatibility while offering active product status and bulk packaging availability.

Key Parameters Governing Substitution:

• Connector Type: Receptacle
• Number of Positions: 3
• Pitch: 0.156" (3.96mm)
• Cable Termination: IDC
• Wire Gauge: 20 AWG
• Contact Finish: Gold at 30.0µin (0.76µm)
• Fastening Type: Locking Ramp
• Mounting Type: Free Hanging (In-Line)

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-641218-3 is the direct equivalent for the obsolete 641218-3.
