The TE Connectivity AMP Connectors part number 3-173977-4 is a single-row IDC receptacle housing from the AMP CT series. It features a 2 mm pitch and accommodates four positions. Designed for cable installation, this component utilizes a right-angle orientation with an integrated cover to protect contacts. The housing is constructed from polybutylene terephthalate (PBT) material, providing durability for industrial applications. It supports a maximum current rating of 2A and operates within a temperature range of -30°C to 105°C. The contacts are tin-plated phosphor bronze, ensuring reliable signal transmission in board-to-wire configurations.
Verify the specific part number against official TE Connectivity documentation to confirm compatibility with mating headers and cable specifications. Ensure that the required current and voltage ratings align with the application's operational demands. Cross-reference the housing material properties and temperature limits to guarantee performance under expected environmental conditions. Confirm that the IDC tooling used matches the 2 mm pitch requirement for proper termination integrity.
Select this component when a right-angle, covered IDC housing is required for a four-position circuit. Consider the 2 mm pitch constraint and the 2A current rating during the design phase. Evaluate the operating temperature range to ensure suitability for the intended environment. Verify that the phosphor bronze contacts with tin plating meet the conductivity and corrosion resistance needs of the system.
This component belongs to the AMP CT series, which offers various connector solutions for diverse connectivity needs. The series is known for its reliability in harsh environments and ease of assembly. As a TE Connectivity product, it adheres to strict manufacturing standards for quality and consistency. The AMP CT line provides engineers with flexible options for board-to-wire connections, supporting both standard and specialized applications across multiple industries.
Consult TE Connectivity official resources for verified substitute part numbers. Ensure any replacement maintains identical pitch, position count, and termination type.
