TE Connectivity 1-172343-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-172343-2 is a 2-position receptacle housing connector from the Mini-Universal MATE-N-LOK series, designed for free-hanging in-line applications with crimp contact termination. This connector features a 0.163" (4.14mm) pitch and operates across a temperature range of -20°C to 105°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-172343-2 is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Receptacle, Front Section from the Mini-Universal MATE-N-LOK series
• Electrical Configuration: 2-position, single-row layout with 0.163" (4.14mm) pitch
• Mechanical Interface: Free-hanging in-line mounting with crimp contact termination and locking ramp fastening
• Material & Environmental Compliance: Polyamide (PA66) insulation, ROHS3 compliance, and -20°C to 105°C operating temperature range

The substitute part 172343-1 maintains identical electrical and mechanical specifications. The primary distinction is product status (active versus obsolete) and connector housing color (natural versus red). Both parts share the same base product number (172343), confirming functional interchangeability within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

The 172343-1 serves as the direct functional equivalent to the obsolete 1-172343-2. Both connectors meet ROHS3 compliance requirements and maintain identical electrical and mechanical specifications across all critical parameters. The 172343-1 is classified as an active product with significantly higher inventory availability (13,655 pieces versus 798 pieces), ensuring reliable supply for ongoing production and field service requirements.

Selection of the 172343-1 is supported by its active product status, which guarantees continued manufacturer support, documentation, and supply chain stability. The housing color difference (natural versus red) does not affect electrical or mechanical performance and is a cosmetic distinction only. Both parts are suitable for applications requiring 2-position receptacle connectors with 4.14mm pitch in the Mini-Universal MATE-N-LOK series.

Frequently Asked Questions (FAQ)

Q: Are the 1-172343-2 and 172343-1 electrically and mechanically interchangeable?

A: Yes. Both connectors share identical specifications for connector type, position count, pitch, mounting configuration, contact termination, and fastening mechanism. They are functionally equivalent within the Mini-Universal MATE-N-LOK series.

Q: What is the significance of the color difference between the red (1-172343-2) and natural (172343-1) housings?

A: Color is a cosmetic feature that does not affect electrical performance, mechanical fit, or environmental compliance. The color distinction may be used for circuit identification or assembly organization but does not impact connector functionality.

Q: Why is the 1-172343-2 classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part number. The 172343-1 represents the active equivalent within the same product family.

Q: What packaging differences exist between these parts?

A: The 1-172343-2 is supplied in unspecified packaging, while the 172343-1 is supplied in bulk packaging. Both are new original stock from TE Connectivity.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1-172343-2 and 172343-1 are ROHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing.

Q: Can the 172343-1 be used as a direct replacement in existing designs using the 1-172343-2?

A: Yes. The 172343-1 maintains all critical electrical and mechanical parameters required for direct substitution. No design modifications are necessary.

Q: What is the operating temperature range for both connectors?

A: Both connectors operate across -20°C to 105°C, providing consistent thermal performance across applications.

Q: Are contacts included with these connector housings?

A: No. Both the 1-172343-2 and 172343-1 are housings only. Contacts must be sourced separately and crimped into the housing.
