TE Connectivity AMP Connectors 6-175778-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 6-175778-2 is a 2-position rectangular connector receptacle housing with 2.00mm pitch, designed for free-hanging in-line applications. This connector features crimp-type female socket contacts and operates across a temperature range of -30°C to 105°C. The housing is constructed from Polyamide (PA66) Nylon 6/6 material and is classified as ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, enabling direct functional replacement in applications where the primary part becomes unavailable or when alternative specifications better suit specific deployment requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6-175778-2 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant across all substitute relationships:

Critical Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 2
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters Permitting Substitution:

• Housing Color
• Insulation Material composition
• Operating Temperature range
• Product Series designation

The identified substitute parts maintain all critical matching parameters while differing in housing color, material composition, or thermal operating specifications. These variations do not affect the core connector interface functionality or electrical performance in standard applications.

Parameter Comparison

Engineering Selection Recommendations

6-175778-2 (Primary Part): This connector is the baseline specification with Polyamide (PA66) Nylon 6/6 insulation material and an operating temperature range of -30°C to 105°C. All three parts maintain Active product status and ROHS3 compliance.

4-179228-2 (Parametric Equivalent): This substitute maintains identical electrical and mechanical specifications to the main part, including the same insulation material composition and operating temperature range. The primary distinction is housing color (Yellow versus Black). This part is suitable for applications where color coding is required for circuit identification or assembly traceability without affecting connector performance.

6-440129-2 (Parametric Equivalent): This substitute maintains the same connector interface specifications and black housing color as the main part. The material composition differs (Thermoplastic versus Polyamide PA66) and the operating temperature range is reduced to -25°C to 85°C. This part is suitable for applications operating within the narrower thermal envelope and where thermoplastic material properties are acceptable.

All three parts are manufactured by TE Connectivity AMP Connectors, carry ROHS3 compliance certification, and maintain MSL 1 (Unlimited) moisture sensitivity rating. Selection between these parts depends on specific application requirements regarding housing color, material composition, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can 4-179228-2 be used as a direct replacement for 6-175778-2?

A: Yes. The 4-179228-2 maintains identical electrical and mechanical specifications including connector type, contact type, position count, pitch, mounting type, and contact termination. The housing color difference (Yellow versus Black) does not affect electrical performance or physical interface compatibility.

Q: What is the primary difference between 6-440129-2 and 6-175778-2?

A: The 6-440129-2 differs in two aspects: insulation material composition (Thermoplastic versus Polyamide PA66) and operating temperature range (-25°C to 85°C versus -30°C to 105°C). The connector interface and electrical specifications remain identical. Selection depends on whether the application operates within the reduced thermal range and whether thermoplastic material properties are acceptable.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—6-175778-2, 4-179228-2, and 6-440129-2—carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL 1 (Unlimited) indicates that these connectors have unlimited shelf life and do not require special moisture control storage conditions. They can be stored and handled under standard environmental conditions without degradation.

Q: Do these connectors include contacts?

A: No. All three parts are connector housings only. Contacts are not included and must be sourced separately as required for the specific application.

Q: What is the pitch specification and why is it important?

A: The pitch is 0.079" (2.00mm), which specifies the center-to-center distance between adjacent contact positions. This parameter is critical for mechanical compatibility and must match the mating connector to ensure proper alignment and electrical connection.

Q: Can 6-440129-2 be used in applications requiring the full -30°C to 105°C temperature range?

A: No. The 6-440129-2 operating temperature range is limited to -25°C to 85°C. Applications requiring operation below -25°C or above 85°C must use 6-175778-2 or 4-179228-2, which both support the extended -30°C to 105°C range.
