TE Connectivity AMP Connectors 4-175778-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-175778-2 is a 2-position rectangular connector receptacle housing with 2.00mm pitch, designed for free-hanging in-line applications. This component belongs to the CT series and features crimp-type female socket contacts with polyamide insulation material. The part is actively produced and RoHS compliant, making it suitable for applications requiring reliable interconnection in temperature ranges from -30°C to 105°C.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector housings, allowing for design flexibility, inventory optimization, or when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4-175778-2 are identified based on strict equivalence of critical electrical and mechanical parameters. The following parameters must remain constant for substitution eligibility:

• 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
• Moisture Sensitivity Level: 1 (Unlimited)

Parameters that may vary between the main part and substitutes include insulation material composition, color, operating temperature range, series designation, and RoHS compliance version. These variations do not prevent functional substitution when the core electrical and mechanical specifications remain aligned.

Parameter Comparison

Engineering Selection Recommendations

4-179228-2 as Primary Substitute:

The 4-179228-2 maintains complete electrical and mechanical equivalence to the 4-175778-2. Both parts share identical connector specifications, pitch, position count, and operating temperature range. The 4-179228-2 carries ROHS3 compliance status, representing a more current regulatory certification than the main part. This substitute is suitable for direct replacement in applications where the CT series yellow receptacle housing is specified. Inventory availability for the 4-179228-2 is significantly higher at 66,157 pieces compared to 910 pieces for the main part.

6-440129-2 as Alternative Substitute:

The 6-440129-2 provides functional substitution with the following considerations: it maintains the same connector type, contact type, position count, pitch, and mounting configuration. However, this part operates within a reduced temperature range of -25°C to 85°C compared to the -30°C to 105°C range of the main part. The 6-440129-2 belongs to the High Performance Interconnect (HPI) series and features thermoplastic insulation rather than polyamide. The color is black rather than yellow. This substitute is appropriate for applications that do not require the extended temperature range of the primary part. Inventory availability is highest at 272,906 pieces.

All three parts maintain active product status and MSL 1 rating, confirming ongoing manufacturing support and unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

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

A: Yes. The 4-179228-2 is a parametric equivalent with identical connector type, contact type, position count, pitch, mounting type, and operating temperature range. Both parts are yellow receptacle housings in the CT series with crimp termination and polyamide insulation.

Q: What is the primary difference between the 4-175778-2 and 6-440129-2?

A: The 6-440129-2 operates within a reduced temperature range (-25°C to 85°C versus -30°C to 105°C), features thermoplastic insulation instead of polyamide, is colored black instead of yellow, and belongs to the HPI series rather than the CT series. All other electrical and mechanical parameters remain equivalent.

Q: Are contacts included with these connector housings?

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

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

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These parts have unlimited shelf life under standard storage conditions and do not require special moisture-controlled packaging or baking procedures prior to assembly.

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

A: No. The 6-440129-2 is rated only to -25°C minimum and 85°C maximum. Applications requiring operation at -30°C or above 85°C must use either the 4-175778-2 or 4-179228-2.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents a more current version of the standard. All three parts meet RoHS requirements and are suitable for applications with RoHS mandates.

Q: Are these parts compatible with the same mating connectors?

A: Yes. All three receptacle housings share the same 2-position, 2.00mm pitch configuration and are compatible with corresponding plug connectors designed for this pitch and position count.
