Key Parameters

Substitute Part Grouping Explanation

Substitution of the 748610-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series: AMPLIMITE HDP-22
• Contact Type: Female Socket
• Wire Gauge: 22-28 AWG
• Contact Termination: Crimp
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 1658686-1 satisfies all mandatory parameters. The primary distinction is that 1658686-1 is classified as an active product with current manufacturing status and improved compliance certifications, whereas 748610-2 is obsolete. Both components are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications within the AMPLIMITE HDP-22 series.

Parameter Comparison

Engineering Selection Recommendations

The 1658686-1 substitute part is functionally equivalent to the 748610-2 across all electrical and mechanical parameters. Selection of 1658686-1 is supported by the following factors:
