TE Connectivity AMP Connectors 4-175778-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-175778-6 is a 6-position rectangular connector receptacle housing with 2.00mm pitch, designed for free-hanging in-line mounting applications. This connector features crimp-type contact termination and is constructed from polyamide (PA66) nylon 6/6 insulation material. The part is actively produced and maintains RoHS compliance with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required but alternative color options, temperature ranges, or manufacturer sources are acceptable for specific application requirements.

Substitute Part Grouping Explanation

Substitute parts for the 4-175778-6 are qualified based on matching the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (6), pitch (2.00mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), insulation material composition (polyamide PA66 nylon 6/6), and RoHS compliance status. Variations in color, operating temperature range, manufacturer, series designation, and specific insulation material additives (such as glass filling) do not affect the core electrical and mechanical compatibility of the housing interface. All identified substitutes maintain the same functional footprint and contact interface specifications required for direct replacement in applications where these parameters are the determining factors for part selection.

Engineering Selection Recommendations

All three parts maintain active product status and full RoHS compliance, qualifying them for use in applications requiring regulatory adherence. The 4-175778-6 and 69305-006LF both support the full operating temperature range of -30°C to 105°C (or -40°C to 105°C for the Amphenol part), making them suitable for applications with elevated temperature requirements. The 179228-6 operates within a narrower temperature window (-55°C to 85°C) and is appropriate for applications where the lower temperature limit is not required below -30°C and the upper limit does not exceed 85°C. The 69305-006LF incorporates glass-filled polyamide insulation, providing enhanced mechanical properties compared to unfilled nylon 6/6 formulations. Selection between these parts should be based on application-specific temperature requirements, environmental conditions, and any design constraints related to connector color or material composition.

Frequently Asked Questions (FAQ)

Q: Can the 179228-6 be used as a direct replacement for the 4-175778-6 in all applications?

A: The 179228-6 is mechanically and electrically compatible with the 4-175778-6 for applications operating within the temperature range of -30°C to 85°C. Applications requiring operation below -30°C or above 85°C must use the 4-175778-6 or 69305-006LF.

Q: What is the primary difference between the 4-175778-6 and 69305-006LF?

A: Both parts support identical operating temperature ranges (-30°C to 105°C and -40°C to 105°C respectively) and share the same electrical and mechanical interface specifications. The 69305-006LF uses glass-filled polyamide insulation, while the 4-175778-6 uses unfilled nylon 6/6. The 69305-006LF is manufactured by Amphenol ICC (FCI) rather than TE Connectivity.

Q: Are contacts included with these connector housings?

A: No. All three parts are housings only. Contacts must be sourced separately and are not included with the connector receptacle.

Q: Do all substitute parts maintain the same pitch and position count?

A: Yes. All substitute parts maintain 6 positions with 0.079" (2.00mm) pitch, ensuring identical mating interface geometry.

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

A: Color is a visual identifier only and does not affect electrical or mechanical performance. Color selection is based on application requirements, assembly identification, or design specifications.

Q: Are all parts RoHS compliant?

A: Yes. The 4-175778-6, 179228-6, and 69305-006LF are all RoHS compliant with MSL 1 (unlimited moisture sensitivity level).
