Molex 0026033191 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0026033191 is a 19-position rectangular connector housing designed for 0.156" (3.96mm) pitch applications. This receptacle housing is part of the KK396 and 6442 series and is configured for crimp contact termination in free-hanging, in-line mounting configurations. The part is Active status and ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0026033191 is determined by strict alignment of the following parameters:

• Connector Type: Must be Receptacle
• Number of Positions: Must be 19
• Pitch: Must be 0.156" (3.96mm)
• Number of Rows: Must be 1
• Mounting Type: Must be Free Hanging (In-Line)
• Contact Termination: Must be Crimp
• Color: Must be Natural
• RoHS Status: Must be ROHS3 Compliant
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The TE Connectivity AMP Connectors part 1-640251-9 meets all mandatory substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0026033191 and TE Connectivity 1-640251-9 are Active status products with ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on:

• Supply availability: Current inventory levels and lead times from respective distributors
• Series compatibility: Molex KK396/6442 series versus TE SL-156 series—verify mechanical fit within your connector assembly
• Thermal requirements: TE Connectivity part provides explicit operating temperature range (-55°C ~ 105°C); confirm this meets your application needs
• Cost and procurement: Compare unit pricing and minimum order quantities from authorized distributors

Both parts are suitable for production use without additional qualification when mechanical and electrical requirements align with the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-640251-9 be used as a direct replacement for the Molex 0026033191?

A: Yes, when all mechanical and electrical parameters match as shown in the Parameter Comparison table. Both are 19-position, 0.156" pitch receptacle housings with crimp termination and identical compliance ratings. Verify series compatibility (KK396/6442 versus SL-156) within your specific connector assembly design.

Q: What does "Contacts Not Included" mean for these housings?

A: Both housings are supplied without pre-installed crimp contacts. Contacts must be sourced separately and crimped into the housing according to manufacturer specifications. Ensure contact part numbers are compatible with the 0.156" pitch and 19-position configuration.

Q: Are there differences in insulation material between these parts?

A: Both use polyamide (nylon) insulation. The Molex part specifies PA66/Nylon 6/6, while the TE part specifies PA/Nylon. These are functionally equivalent for the stated application parameters.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these housings have unlimited shelf life and do not require special moisture-controlled storage or baking procedures prior to assembly.

Q: How do I verify mechanical compatibility with my existing connector design?

A: Confirm that your mating connector is designed for 0.156" pitch, 19-position, single-row receptacle housings. Cross-reference the series designation (KK396/6442 for Molex; SL-156 for TE) with your connector documentation to ensure mechanical fit and keying alignment.
