TE Connectivity 794238-1 Rectangular Connector Receptacle Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794238-1 is a 2-position rectangular connector receptacle housing from the Mini-Universal MATE-N-LOK II series. This component serves as the housing structure for receptacle-type connectors in applications requiring free-hanging, in-line mounting with crimp contact termination. The part is currently active in production with 1026 pieces available in new original inventory stock.

Substitute parts are identified when equivalent rectangular connector housings share identical electrical and mechanical parameters, including connector type, number of positions, row configuration, row spacing, mounting method, contact termination type, fastening mechanism, insulation material, and compliance certifications. Identifying qualified substitutes ensures design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 794238-1 are qualified based on strict equivalence across all provided electrical and mechanical parameters. The substitution logic requires that alternative parts maintain identical specifications in the following critical areas:

Electrical Parameters:

• Connector type (Receptacle)
• Number of positions (2)
• Row configuration (2 rows)
• Row spacing (0.163" / 4.14mm)

Mechanical Parameters:

• Mounting type (Free Hanging, In-Line)
• Contact termination method (Crimp)
• Fastening type (Locking Ramp)
• Insulation material (Polyamide/Nylon)
• Color (Natural)

Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level (MSL 1)
• Product status (Active)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations from specified parameters are permitted in the substitution classification.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 794185-1 is a direct parametric equivalent to the 794238-1 across all specified electrical, mechanical, and compliance parameters. Both parts are manufactured by TE Connectivity within the Mini-Universal MATE-N-LOK II series and maintain identical connector specifications, mounting configurations, and material properties.

Both parts carry active product status and RoHS compliance certification, confirming ongoing manufacturing support and regulatory alignment. The MSL 1 rating for both parts indicates unlimited moisture sensitivity protection, suitable for standard storage and handling conditions.

The 794185-1 substitute provides higher current inventory availability (4410 pieces versus 1026 pieces), which may support supply chain requirements. The substitute part additionally specifies an operating temperature range of -55°C to 105°C, providing defined thermal performance parameters not explicitly stated for the main part.

Selection between these equivalent parts should be based on inventory availability, lead time requirements, and any application-specific thermal performance needs within the specified operating range.

Frequently Asked Questions (FAQ)

Q: Are the 794238-1 and 794185-1 interchangeable in all applications?

A: Yes. Both parts are parametric equivalents sharing identical connector type, position count, row configuration, row spacing, mounting method, contact termination, fastening mechanism, insulation material, and compliance certifications. They are direct substitutes within the Mini-Universal MATE-N-LOK II series.

Q: What is the difference between these two part numbers?

A: The parts are electrically and mechanically identical. The primary differences are the base product numbers (794238 versus 794185) and current inventory levels. The 794185-1 additionally specifies an operating temperature range of -55°C to 105°C.

Q: Do both parts require the same contact types?

A: Both parts are receptacle housings designed for crimp-terminated contacts. The specification states "Contacts Not Included" for both parts, indicating that contacts must be sourced separately and are compatible with both housing types.

Q: Can I use these parts in applications requiring specific temperature performance?

A: The 794185-1 specifies an operating temperature range of -55°C to 105°C. If your application requires operation within this range, the 794185-1 provides documented thermal performance. The 794238-1 does not specify an operating temperature range in the provided data.

Q: Are both parts RoHS compliant?

A: Yes. Both the 794238-1 and 794185-1 carry RoHS Compliant certification, confirming compliance with restricted substance regulations.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited moisture sensitivity protection. Both parts do not require special moisture control during storage or handling, simplifying inventory management and logistics.

Q: Which part should I select if both are available?

A: Selection should be based on inventory availability and application requirements. The 794185-1 offers higher current stock (4410 pieces) and specified thermal performance (-55°C to 105°C). The 794238-1 may be selected if specific design documentation or legacy system requirements reference this part number.

Q: Are these parts suitable for free-hanging, in-line mounting applications?

A: Yes. Both parts are specified for Free Hanging (In-Line) mounting type, making them suitable for applications requiring flexible, non-panel-mounted connector configurations.
