TE Connectivity AMP Connectors 66429-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 66429-4 is an active pin contact designed for the Multimate III+ connector series. This stamped brass contact with gold finish is engineered for crimp termination on wire gauges 26-30 AWG. The component is supplied in bulk packaging and maintains unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts may be required due to packaging availability, inventory levels, or specific procurement requirements while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 66429-4 is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts must belong to the Multimate III+ connector series
• Contact Configuration: Pin contact type with identical stamped construction
• Termination Method: Crimp termination for 26-30 AWG wire gauge
• Material Specification: Brass base material with gold finish at 30.0µin (0.76µm) thickness
• Electrical Performance: Identical contact material and finish ensure equivalent electrical characteristics
• Environmental Rating: MSL 1 (Unlimited) rating maintained across all substitutes
• Regulatory Classification: EAR99 ECCN and 8536.90.4000 HTSUS code consistency

The substitute part 66429-4 and 66425-8 share identical functional specifications. The primary distinction is packaging format: bulk versus cut tape. Both parts are manufactured by TE Connectivity AMP Connectors and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the 66429-4 and 66425-8 are active products manufactured by TE Connectivity AMP Connectors with identical electrical and mechanical specifications for the Multimate III+ series. Selection between these parts is based on the following factors:
