Molex 0026033091 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0026033091 is a 9-position rectangular connector housing with 0.156" (3.96mm) pitch, designed for crimp contact termination in free-hanging inline applications. This receptacle housing is part of the KK396 and 6442 series and maintains Active product status. Alternative equivalent parts may be required due to inventory availability, supply chain considerations, or specific application requirements for different insulation material compositions or operating temperature specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0026033091 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• Connector type: Receptacle
• Number of positions: 9
• Pitch: 0.156" (3.96mm)
• Number of rows: 1
• Mounting type: Free Hanging (In-Line)
• Contact termination: Crimp
• Color: Natural

Secondary Considerations:

• Insulation material composition (Polyamide PA66 vs. Polyester Glass Filled)
• Operating temperature range specifications
• RoHS and REACH compliance status
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts listed maintain all primary matching criteria, ensuring mechanical and electrical compatibility with the original part in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and meet RoHS compliance requirements. The Molex 0026033091 and 0009508090 are both ROHS3 compliant and REACH unaffected. The TE Connectivity 640251-9 is RoHS compliant with vendor-undefined REACH status.

Selection between these parts should be based on:

1. Insulation Material Requirements: The original Molex 0026033091 uses PA66 nylon, while the Molex 0009508090 uses polyester glass-filled material. The TE Connectivity 640251-9 uses standard polyamide nylon. Material selection depends on specific environmental and mechanical stress conditions in the application.

2. Operating Temperature Specification: The TE Connectivity 640251-9 provides explicit operating temperature range (-55°C ~ 105°C). If operating temperature specifications are critical to the application, this part provides documented thermal performance data.

3. Supply Chain Availability: All three parts are in active stock with varying inventory levels (Molex 0026033091: 856 pcs, TE Connectivity 640251-9: 1885 pcs, Molex 0009508090: 25163 pcs).

4. Regulatory Compliance: For applications requiring REACH compliance documentation, the Molex parts (0026033091 and 0009508090) provide explicit REACH unaffected status, while the TE Connectivity part has vendor-undefined REACH status.

Frequently Asked Questions (FAQ)

Q: Are these parts mechanically interchangeable?

A: Yes. All three parts share identical mechanical specifications: 9-position receptacle housings with 0.156" (3.96mm) pitch, single-row configuration, free-hanging inline mounting, and crimp contact termination. They are designed for the same connector interface.

Q: What is the difference in insulation materials between these parts?

A: The Molex 0026033091 uses PA66 nylon (Nylon 6/6), the TE Connectivity 640251-9 uses standard polyamide nylon, and the Molex 0009508090 uses polyester with glass filler. These material differences may affect mechanical strength, temperature resistance, and chemical compatibility depending on the application environment.

Q: Does the TE Connectivity 640251-9 have documented operating temperature specifications?

A: Yes. The TE Connectivity 640251-9 specifies an operating temperature range of -55°C to 105°C. The Molex parts do not provide explicit operating temperature specifications in the available data.

Q: Are contacts included with these housings?

A: No. All three parts are housings only. Contacts must be sourced separately and are not included with any of these parts.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and do not require special moisture control during storage or handling. This applies to all three substitute parts.

Q: Which part should I select for a new design?

A: Selection depends on application-specific requirements. For standard applications with no extreme temperature requirements, any of the three parts are suitable. For applications requiring documented operating temperature specifications, the TE Connectivity 640251-9 is the appropriate choice. For applications requiring explicit REACH compliance documentation, either Molex part (0026033091 or 0009508090) is suitable.

Q: Are these parts RoHS compliant?

A: Yes. The Molex 0026033091 and 0009508090 are ROHS3 compliant. The TE Connectivity 640251-9 is RoHS compliant. All three parts meet RoHS requirements for new designs.
