TE Connectivity AMP Connectors 3-175778-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 3-175778-4 is a 14-position rectangular connector receptacle housing with 2.00mm pitch, designed for free-hanging in-line mounting applications. This component features crimp-style female socket contacts and is constructed from polyamide (PA66) nylon 6/6 insulation material. The part maintains active product status and operates across a temperature range of -30°C to 105°C. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative housing colors, series designations, or material compositions are acceptable for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3-175778-4 are identified based on matching core electrical and mechanical parameters: 14-position receptacle configuration, 2.00mm pitch, female socket contact type, crimp termination, free-hanging in-line mounting, and single-row arrangement. All substitute parts maintain ROHS3 compliance and MSL Level 1 rating.

Substitution logic is organized into two categories:

Category 1: Series CT Housing Color Variant The part 1-179228-4 maintains identical electrical and mechanical specifications to the main part, differing only in housing color (natural versus blue) and base product number. Both parts utilize polyamide (PA66) nylon 6/6 insulation material and operate across the same temperature range (-30°C to 105°C).

Category 2: High Performance Interconnect (HPI) Series Alternative The part 1-440129-4 provides functional equivalence across all critical connector parameters (14 positions, 2.00mm pitch, female socket, crimp termination, free-hanging mounting). This part operates within a narrower temperature range (-25°C to 85°C) and utilizes thermoplastic insulation material rather than polyamide (PA66) nylon 6/6. The HPI series designation indicates a different product line within TE Connectivity's connector portfolio.

Parameter Comparison

Engineering Selection Recommendations

1-179228-4 Selection Criteria

The 1-179228-4 substitute part is functionally equivalent to the 3-175778-4 across all electrical and mechanical parameters. Both parts share identical connector specifications, temperature operating range, insulation material composition, and regulatory compliance status. Selection of 1-179228-4 is appropriate when housing color differentiation is not a design constraint. This part maintains the same CT series designation and provides equivalent performance characteristics for applications requiring 14-position, 2.00mm pitch receptacle housings with crimp termination.

1-440129-4 Selection Criteria

The 1-440129-4 substitute part provides functional equivalence for core connector parameters (14 positions, 2.00mm pitch, female socket, crimp termination, free-hanging mounting) but operates within a reduced temperature range (-25°C to 85°C compared to -30°C to 105°C). This part utilizes thermoplastic insulation material rather than polyamide (PA66) nylon 6/6. Selection of 1-440129-4 is appropriate for applications where the narrower operating temperature range and alternative insulation material are compatible with system requirements. The HPI series designation indicates this part belongs to TE Connectivity's High Performance Interconnect product line.

Both substitute parts maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with the main part.

Frequently Asked Questions (FAQ)

Q: What are the primary differences between 3-175778-4 and 1-179228-4?

A: The 3-175778-4 and 1-179228-4 are electrically and mechanically equivalent 14-position rectangular connector receptacles with 2.00mm pitch. The primary difference is housing color: 3-175778-4 features blue housing while 1-179228-4 features natural housing. Both parts utilize identical polyamide (PA66) nylon 6/6 insulation material, operate across -30°C to 105°C, and maintain ROHS3 compliance.

Q: Can 1-440129-4 replace 3-175778-4 in all applications?

A: The 1-440129-4 provides functional equivalence for connector configuration and termination type but operates within a narrower temperature range (-25°C to 85°C versus -30°C to 105°C). Additionally, 1-440129-4 utilizes thermoplastic insulation material rather than polyamide (PA66) nylon 6/6. Substitution is appropriate only when application operating temperatures remain within -25°C to 85°C and thermoplastic insulation material is compatible with system requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 3-175778-4, 1-179228-4, and 1-440129-4 all maintain ROHS3 compliance status. All three parts also carry MSL Level 1 (Unlimited) moisture sensitivity rating and EAR99 export classification.

Q: What is the significance of the series designation difference between CT and HPI?

A: The series designation indicates the product line within TE Connectivity's connector portfolio. The 3-175778-4 and 1-179228-4 belong to the CT series, while 1-440129-4 belongs to the High Performance Interconnect (HPI) series. Series differences may reflect design generation, performance characteristics, or manufacturing process variations, though all three parts meet the specified 14-position, 2.00mm pitch receptacle requirements.

Q: Do these parts include contacts?

A: No. All three parts (3-175778-4, 1-179228-4, and 1-440129-4) are connector housings only. Contacts are not included and must be sourced separately.

Q: What mounting configuration do these parts support?

A: All three parts support free-hanging in-line mounting configuration with crimp-style contact termination. This mounting type is suitable for applications requiring flexible connector positioning without fixed mounting hardware.
