TE Connectivity 794243-1 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794243-1 is a 6-position rectangular connector plug housing from the Mini-Universal MATE-N-LOK II series. This connector housing is designed for free-hanging, in-line applications with crimp contact termination and latch lock fastening. The part is currently active in production status and maintains full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific design requirements necessitate alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector plug housings is determined by strict equivalence across the following critical parameters: connector type (plug), number of positions (6), pitch spacing (0.163" / 4.14mm), number of rows (2), row spacing (0.163" / 4.14mm), mounting configuration (free hanging in-line), contact termination method (crimp), and fastening mechanism (latch lock). All identified substitute parts maintain these core electrical and mechanical specifications. Variations in color (natural versus red) and series designation (Mini-Universal MATE-N-LOK versus Mini-Universal MATE-N-LOK II) do not affect functional interchangeability within the specified parameter set. All substitute parts carry identical RoHS3 compliance and MSL 1 ratings.

Parameter Comparison

Engineering Selection Recommendations

All three connector plug housings maintain active production status and full ROHS3 compliance. Selection between the main part number 794243-1 and substitute parts 1-172168-2 or 794190-1 is based on application-specific requirements and availability constraints.

Part 794243-1 and 794190-1 are functionally equivalent, both belonging to the Mini-Universal MATE-N-LOK II series with natural color insulation material. These parts are interchangeable for applications where series consistency and color specification are design requirements.

Part 1-172168-2 represents an alternative from the Mini-Universal MATE-N-LOK series with red color insulation and PA66 nylon material specification. This part maintains all critical electrical and mechanical parameters required for functional compatibility. The operating temperature range of -20°C to 105°C is specified for this part, whereas operating temperature data is not provided for the other two parts. Selection of 1-172168-2 is appropriate when color differentiation is required or when the specified operating temperature range aligns with application requirements.

All parts carry identical MSL 1 ratings, indicating unlimited moisture sensitivity protection and suitability for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts mechanically compatible with the main part 794243-1?

A: Yes. All substitute parts maintain identical pitch spacing (0.163" / 4.14mm), row configuration (2 rows with 0.163" spacing), mounting type (free hanging in-line), and fastening mechanism (latch lock). Mechanical interchangeability is confirmed across all three part numbers.

Q: What is the functional difference between the Mini-Universal MATE-N-LOK II series and the Mini-Universal MATE-N-LOK series?

A: Both series maintain identical electrical and mechanical specifications for the 6-position, 4.14mm pitch connector housings. Series designation does not affect functional performance or interchangeability within the specified parameter set.

Q: Does the color difference between natural and red housing affect electrical performance?

A: No. Color is a cosmetic specification that does not impact electrical functionality or mechanical compatibility. Selection between natural and red housings is determined by application requirements for circuit identification or visual differentiation.

Q: What is the significance of the PA66 nylon material specification in part 1-172168-2?

A: PA66 (Nylon 6/6) is a polyamide variant with specific material properties. Both PA and PA66 materials are suitable for the specified connector application. Material selection does not affect interchangeability when all other electrical and mechanical parameters are equivalent.

Q: Are all three parts suitable for the same crimp contact specifications?

A: Yes. All three parts are designed for crimp contact termination and accept the same contact types. Contact specifications are determined by the contact part number, not the housing part number.

Q: What does MSL 1 rating indicate for these connector housings?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no special moisture protection requirements during storage or handling. These parts do not require desiccant packaging or controlled humidity environments.

Q: Can these connector housings be used interchangeably in existing designs?

A: Interchangeability is confirmed for applications where the specified electrical and mechanical parameters are the design requirements. Design reviews should confirm that series designation, color specification, and material composition do not impose additional constraints on part selection.
