TE Connectivity 174057-4 Rectangular Connector Receptacle Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 174057-4 is a 2-position rectangular connector receptacle housing from the Multi-Lock series, designed for free-hanging in-line applications with crimp contact termination. This component operates across a temperature range of -30°C to 105°C and is constructed from polybutylene terephthalate (PBT) insulation material. The part is actively produced and maintains full RoHS3 compliance with REACH unaffected status. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained while allowing for variations in non-critical attributes such as housing color.

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 174057-4 are identified based on strict equivalence of the following critical parameters:

• Connector Type: Receptacle housing only
• Number of Positions: 2-position configuration
• Pitch Specification: 0.102" (2.60mm) contact spacing
• Number of Rows: Single row layout
• Mounting Type: Free hanging in-line orientation
• Contact Termination Method: Crimp termination
• Insulation Material: Polybutylene terephthalate (PBT)
• Operating Temperature Range: -30°C to 105°C
• Series Designation: Multi-Lock series
• Compliance Standards: RoHS3 compliant, REACH unaffected

The substitute part 174057-2 maintains all critical electrical and mechanical parameters. The only variation is the housing color (black versus green), which does not affect functional compatibility, electrical performance, or mechanical fit. Both parts are manufactured by TE Connectivity AMP Connectors and share the same base product number 174057.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 174057-4 and 174057-2 are active production components with identical compliance certifications. Selection between these parts should be based on application-specific requirements:

TE Connectivity 174057-4 (Green Housing): Select this part when color coding or visual identification requirements specify green housing for circuit board assembly or wiring harness applications.

TE Connectivity 174057-2 (Black Housing): Select this part when color coding or visual identification requirements specify black housing, or when the 174057-4 is unavailable. The black variant maintains full functional and electrical equivalence.

Both parts carry RoHS3 compliance and REACH unaffected status, making them suitable for applications subject to environmental and regulatory restrictions. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling. All electrical and mechanical parameters remain constant across both variants, ensuring direct interchangeability in circuit designs and mechanical assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 174057-2 (black) be used as a direct replacement for the 174057-4 (green)?

A: Yes. The 174057-2 is a direct functional equivalent. All electrical parameters, mechanical dimensions, contact configuration, pitch spacing, mounting type, and operating temperature range are identical. The only difference is housing color.

Q: Are there any electrical performance differences between the green and black variants?

A: No. Both parts use identical polybutylene terephthalate (PBT) insulation material, operate across the same temperature range (-30°C to 105°C), and employ the same crimp contact termination method. Electrical performance is equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 174057-4 and 174057-2 are RoHS3 compliant and REACH unaffected. They carry identical regulatory certifications and are suitable for applications with environmental compliance requirements.

Q: What is the significance of the 0.102" (2.60mm) pitch specification?

A: The pitch specification defines the center-to-center distance between contact positions. Both parts maintain 0.102" (2.60mm) pitch, ensuring mechanical and electrical compatibility with mating connectors and contact assemblies designed for this spacing.

Q: Are contacts included with these housing parts?

A: No. Both the 174057-4 and 174057-2 are receptacle housings only. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.

Q: What does "Free Hanging (In-Line)" mounting type mean?

A: This indicates the connector is designed for direct attachment to cable or wire harnesses without requiring a panel or PCB mounting bracket. Both parts support this mounting configuration.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not include specific color-coding requirements. The mechanical fit, electrical performance, and functional characteristics are identical between the two parts.

Q: What is the Moisture Sensitivity Level (MSL) rating of 1?

A: MSL 1 (Unlimited) indicates these components have no moisture sensitivity constraints. They can be stored and handled without special humidity control measures or baking procedures prior to assembly.
