Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B5743-106-M-L-3 is determined by the following critical parameters:

• Connector type (Header), contact type (Male Pin), and pitch (0.079" / 2.00mm)
• Number of positions (6) and row configuration (1 row)
• Mounting style (Through Hole, Right Angle) and shrouding design (Shrouded - 4 Wall)
• Termination method (Solder) and fastening type (Latch Lock)
• Electrical ratings: Current (2.2A) and Voltage (120V)
• Operating temperature range (-55°C ~ 125°C)
• Material specifications: Contact material (Phosphor Bronze), insulation material (PBT, Glass Filled), and flammability rating (UL94 V-0)

The M80-8760622 qualifies as a direct substitute based on matching all critical parameters within the allowed tolerance ranges for this connector category.

Parameter Comparison

Engineering Selection Recommendations
