TE Connectivity AMP Connectors 175778-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 175778-5 is a 5-position rectangular connector receptacle housing with 2.00mm pitch, designed for free-hanging in-line applications. This component is classified as an active product and is RoHS compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity while maintaining connector interface compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 175778-5 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 5
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• RoHS Compliance: Required

Secondary Considerations:

• Operating Temperature Range (minimum -25°C or lower acceptable)
• Insulation Material composition (thermoplastic or polyamide variants acceptable)
• Product Status: Active

The identified substitute parts 440129-5 and 69305-005LF meet all primary substitution criteria. Variations in insulation material composition, color, and operating temperature upper/lower bounds do not preclude substitution when the core electrical and mechanical interface parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

175778-5 (TE Connectivity CT Series): Select this part for applications requiring the CT series connector family with standard polyamide insulation material and natural color housing. This part maintains the specified operating temperature range of -30°C to 105°C and is actively manufactured with RoHS compliance.

440129-5 (TE Connectivity HPI Series): This substitute is suitable for applications compatible with the High Performance Interconnect (HPI) series. The thermoplastic insulation material and operating temperature range of -25°C to 105°C provide equivalent performance for most standard applications. Inventory availability is significantly higher (137,217 pieces) compared to the main part.

69305-005LF (Amphenol ICC Minitek® MezzSelect™ Basics+): This substitute offers the widest operating temperature range (-40°C to 105°C) and glass-filled polyamide insulation for enhanced mechanical properties. The black color housing and REACH-affected status distinguish this option. This part is suitable for applications requiring extended low-temperature performance or enhanced material durability.

All three parts are RoHS compliant, active products with unlimited moisture sensitivity classification (MSL 1), and maintain the critical 5-position, 2.00mm pitch, single-row, free-hanging in-line configuration with crimp termination.

Frequently Asked Questions (FAQ)

Q: Can 440129-5 be used as a direct replacement for 175778-5?

A: Yes. Both parts share identical electrical and mechanical interface parameters: 5-position receptacle, 2.00mm pitch, single row, free-hanging in-line mounting, and crimp termination. The primary difference is the insulation material composition (thermoplastic versus polyamide) and a 5°C reduction in minimum operating temperature (-25°C versus -30°C). For applications operating above -25°C, this substitute is functionally equivalent.

Q: What is the difference between 69305-005LF and the other substitutes?

A: The 69305-005LF is manufactured by Amphenol ICC rather than TE Connectivity and features a black housing instead of natural color. The insulation material is glass-filled polyamide, providing enhanced mechanical strength. The operating temperature range extends to -40°C, offering superior low-temperature performance. This part is REACH-affected, whereas the other parts have undefined REACH status.

Q: Are contacts included with these connector housings?

A: No. All three parts (175778-5, 440129-5, and 69305-005LF) are connector housings only. Contacts are not included and must be sourced separately.

Q: Does connector color affect substitution compatibility?

A: Color is a cosmetic parameter and does not affect electrical or mechanical compatibility. The natural color of 175778-5 and 440129-5 versus the black color of 69305-005LF does not impact functional substitution. Color selection should be based on application requirements or assembly identification standards.

Q: What is the significance of the MSL rating for these parts?

A: All three parts carry MSL 1 (Unlimited) classification, indicating unlimited shelf life without moisture bake-out requirements. This simplifies inventory management and storage procedures across all substitute options.

Q: Can these parts be used interchangeably in the same assembly?

A: Yes, provided the mating connector is compatible with the 2.00mm pitch, 5-position receptacle interface. The insulation material and color variations do not affect mating compatibility. However, applications with specific low-temperature requirements below -25°C should use 69305-005LF to ensure the -40°C minimum operating temperature specification.
