Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8-146273-9 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Number of Positions: 78
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Current Rating: 3A
• Operating Temperature Range: -65°C ~ 105°C

Mechanical Compatibility Parameters:

• Connector Type: Header, Breakaway
• Mounting Type: Through Hole
• Style: Board to Board or Cable
• Fastening Type: Push-Pull
• Contact Shape: Square
• Insulation Material: Liquid Crystal Polymer (LCP)

Material & Compliance Parameters:

• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Material Flammability Rating: UL94 V-0
