Key Parameters

Substitute Part Grouping Explanation

Substitution of the 646442-9 connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle, Female Sockets)
• Number of positions (176)
• Pitch specification (0.079" / 2.00mm)
• Number of rows (8)
• Current rating (1.5 A minimum)
• Voltage rating (750Vrms minimum)
• Operating temperature range (-55°C to 125°C)

Mechanical Compatibility Parameters:

• Mounting type (Board Edge, Through Hole, Right Angle)
• Termination method (Press-Fit)
• Contact finish (Gold)
• Contact finish thickness (30.0µin / 0.76µm)

Regulatory & Compliance Parameters:

• Series designation (Z-PACK)
• RoHS compliance status
• REACH compliance status

Substitute parts must match all electrical and mechanical parameters without exception. Variations in product status (active versus obsolete) and packaging format do not affect functional interchangeability when all specified parameters align.
