TE Connectivity AMP Connectors 175778-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 175778-7 is a 7-position rectangular connector housing designed for receptacle applications with a 2.00mm pitch. This component functions as a female socket housing for free-hanging, in-line mounting configurations and requires separate crimp contacts for assembly. The part is actively manufactured and maintains ROHS3 compliance with unlimited moisture sensitivity rating. Substitute parts are identified to address inventory availability, color specification requirements, or extended operating temperature ranges while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 7
• Pitch: 0.079" (2.00mm)
• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Insulation Material: Polyamide (PA66), Nylon 6/6
• Series: CT

Allowable Variation Parameters:

• Color: Natural or Black
• Operating Temperature Range: Extended ranges acceptable if minimum meets or exceeds -30°C and maximum meets or exceeds 105°C
• Inventory Status: Independent of substitution eligibility

The substitute part 6-179228-7 maintains identical electrical and mechanical specifications across all mandatory parameters. The primary differences are cosmetic (color: Black versus Natural) and thermal capability (extended lower temperature limit of -65°C versus -30°C), both of which represent acceptable variations for component substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the 175778-7 and 6-179228-7 are active, ROHS3-compliant products manufactured by TE Connectivity AMP Connectors within the CT series. Selection between these parts is based on application-specific requirements rather than compliance or availability concerns, as both maintain identical regulatory certifications and product status.

Selection Criteria:

Choose 175778-7 (Natural Color) when:

• Color specification explicitly requires natural or undyed polyamide housing
• Visual identification or aesthetic requirements mandate the natural finish
• Existing inventory or supply chain preferences favor this variant

Choose 6-179228-7 (Black Color) when:

• Color specification requires black housing for visual identification or environmental protection
• Extended lower operating temperature capability (-65°C minimum) is required for the application
• Black color provides improved UV resistance or environmental durability in outdoor applications
• Inventory availability or lead time considerations favor this variant

Both parts are suitable for identical electrical and mechanical applications. The choice between them is determined by color requirement and thermal operating range specification rather than functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can 6-179228-7 be used as a direct replacement for 175778-7 in all applications?

A: Yes, 6-179228-7 is electrically and mechanically equivalent to 175778-7 across all critical parameters including position count, pitch, mounting type, and contact termination. The substitute part exceeds the thermal specification of the main part, making it suitable for all applications within the original operating temperature range and beyond. The only difference is housing color (Black versus Natural).

Q: What is the significance of the color difference between these parts?

A: The color difference is cosmetic and does not affect electrical or mechanical function. Natural color refers to undyed polyamide (PA66/Nylon 6/6), while Black indicates pigmented polyamide. Color selection is determined by application requirements such as visual identification, environmental protection, or aesthetic specifications. Both materials are identical polyamide compounds with identical mechanical properties.

Q: Does the extended operating temperature range of 6-179228-7 (-65°C to 105°C versus -30°C to 105°C) indicate superior quality?

A: No. The extended lower temperature limit of 6-179228-7 represents a specification difference, not a quality difference. Both parts are manufactured to identical standards and comply with ROHS3 requirements. The extended temperature range of the substitute part simply provides additional capability for applications requiring operation below -30°C. For applications operating within -30°C to 105°C, both parts perform identically.

Q: Are the crimp contacts interchangeable between 175778-7 and 6-179228-7?

A: Yes. Both housings accept identical crimp contacts due to matching position count (7), pitch (2.00mm), and contact type (Female Socket). Contacts are not included with either housing and must be sourced separately. The same contact part numbers are compatible with both housing variants.

Q: What does "Contacts Not Included" mean for these connector housings?

A: These parts are connector housings only. The female socket contacts must be purchased separately and inserted into the housing through the crimp termination process. The housing provides the structural framework and insulation for the contact assembly. Contact selection is independent of housing selection, provided the contact specifications match the 7-position, 2.00mm pitch, female socket configuration.

Q: Can these parts be used in applications requiring solder termination instead of crimp termination?

A: No. Both 175778-7 and 6-179228-7 are specified for crimp contact termination only. The housing design and contact interface are engineered exclusively for crimp-style contacts. Solder termination is not supported by these housings.

Q: What is the significance of the CT series designation?

A: CT is the product series identifier for this family of TE Connectivity AMP rectangular connectors. All parts within the CT series share compatible mechanical and electrical specifications within their respective position and pitch categories. The series designation ensures consistency in design standards and interchangeability within the series family.

Q: Are both parts suitable for free-hanging, in-line mounting applications?

A: Yes. Both 175778-7 and 6-179228-7 are specified for Free Hanging (In-Line) mounting type. This mounting configuration allows the connector housing to be suspended in-line within a cable or harness assembly without requiring panel or bracket mounting. The housing design supports this mounting method identically for both variants.
