Equivalent & Substitute Parts for TE Connectivity 4-175778-3

Part Overview

The TE Connectivity 4-175778-3 is a 3-position rectangular connector receptacle housing with a 2.00mm pitch, designed for free-hanging in-line mounting applications. This component features crimp-style female socket contacts and operates across a temperature range of -30°C to 105°C. The part is manufactured from polyamide (PA66) nylon 6/6 material and is available in yellow insulation. As an active product with RoHS compliance and unlimited moisture sensitivity rating, this connector serves as a standard interconnect solution in electronic assemblies. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when specific design requirements necessitate alternative material compositions or color specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 4-175778-3 is determined by strict alignment with the following core parameters: connector type (receptacle), contact type (female socket), number of positions (3), pitch (2.00mm), number of rows (1), mounting type (free hanging in-line), and contact termination method (crimp). All identified substitute parts maintain these electrical and mechanical specifications without deviation.

The substitute parts are grouped into two categories based on manufacturer and series designation:

TE Connectivity AMP Connectors (High Performance Interconnect Series): Parts 440129-3 and 6-440129-3 are functionally equivalent receptacle housings from the HPI series. These parts differ from the main part in insulation material composition (thermoplastic versus polyamide nylon 6/6) and color designation (natural and black respectively, versus yellow). Operating temperature ranges vary slightly: 440129-3 operates at -25°C to 105°C, while 6-440129-3 operates at -25°C to 85°C.

Amphenol ICC (FCI) Minitek® MezzSelect™ Series: Part 69305-003LF is a cross-manufacturer equivalent from the Minitek® MezzSelect™ and Basics+ series. This part features polyamide (PA66) nylon 6/6 material with glass filling and operates across -40°C to 105°C, providing an extended lower temperature capability compared to the main part.

All substitute parts maintain RoHS compliance, unlimited moisture sensitivity rating (MSL 1), and crimp contact termination. Substitution is valid when the design application permits variation in insulation material type, color specification, and operating temperature boundaries within the stated ranges.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full RoHS compliance, confirming their suitability for current design implementations and regulatory requirements.

TE Connectivity 440129-3 (Natural): This substitute is appropriate for applications where the operating temperature minimum of -25°C satisfies design requirements. The thermoplastic insulation material provides equivalent functional performance to the main part within the specified temperature envelope. This part offers the highest inventory availability among TE Connectivity substitutes.

TE Connectivity 6-440129-3 (Black): This substitute is suitable for applications with maximum operating temperatures not exceeding 85°C. The thermoplastic insulation material and black color designation differentiate this part from the main specification. This part provides the largest inventory stock across all identified substitutes.

Amphenol ICC 69305-003LF (Black): This substitute provides extended lower temperature capability to -40°C, making it suitable for applications requiring enhanced cold-temperature performance. The glass-filled polyamide (PA66) nylon 6/6 insulation material offers material composition closer to the main part than the TE Connectivity HPI series alternatives. This part is appropriate when cross-manufacturer sourcing is acceptable and extended temperature range is required.

Selection between substitutes depends on specific application requirements regarding operating temperature boundaries, insulation material composition, color specification, and acceptable manufacturer sourcing. All parts are functionally equivalent within their stated parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can 440129-3 be used as a direct replacement for 4-175778-3?

A: Yes, 440129-3 is a parametric equivalent substitute. Both parts share identical connector type, contact type, position count, pitch, row configuration, mounting type, and contact termination. The primary differences are insulation material (thermoplastic versus polyamide nylon 6/6), color (natural versus yellow), and operating temperature minimum (-25°C versus -30°C). Substitution is valid when the application does not require operation below -25°C and accepts thermoplastic insulation material.

Q: What is the difference between 6-440129-3 and 440129-3?

A: Both parts are from the TE Connectivity High Performance Interconnect series and share identical electrical and mechanical specifications. The differences are color designation (black versus natural) and maximum operating temperature (85°C versus 105°C). Part 6-440129-3 is suitable only for applications with maximum operating temperatures not exceeding 85°C.

Q: Why would 69305-003LF be selected over the TE Connectivity alternatives?

A: Part 69305-003LF is selected when extended lower temperature operation to -40°C is required, as it provides the lowest minimum operating temperature among all identified substitutes. Additionally, this part features glass-filled polyamide (PA66) nylon 6/6 insulation material, which more closely matches the main part's material composition than the thermoplastic alternatives. Cross-manufacturer sourcing from Amphenol ICC (FCI) may also be preferred for supply chain diversification.

Q: Are all substitute parts RoHS compliant?

A: Yes, all identified substitute parts are RoHS compliant and carry unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of the main part 4-175778-3.

Q: Do substitute parts include contacts?

A: No, all parts in this comparison, including the main part and all substitutes, are connector housings only. Contacts are not included and must be sourced separately.

Q: Can color differences affect electrical performance?

A: No, color designation is a visual identifier only and does not affect electrical performance or functional compatibility. Color differences between parts reflect manufacturing series variations and do not impact circuit operation.

Q: What inventory considerations apply to these substitutes?

A: Inventory availability varies significantly among substitutes. Part 6-440129-3 has the highest stock level at 57,079 pieces, followed by 440129-3 at 3,663 pieces, and 69305-003LF at 1,501 pieces. The main part 4-175778-3 has 1,009 pieces in stock. Inventory levels should be confirmed at time of procurement.
