Molex 0334722303 Rectangular Connector Housing – Equivalent & Substitute Parts

Part Overview

The Molex 0334722303 is a 20-position rectangular connector receptacle housing designed for the MX150 33472 series. This component functions as a female socket housing with a 3.50mm pitch, configured in a 2-row arrangement for free-hanging in-line applications. The housing features sealed construction with glass-filled insulation material and utilizes crimp-type contact termination with latch holder fastening.

This part is classified as Active product status. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity while maintaining full functional compatibility.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334722303 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Core Equivalence Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (20)
• Pitch specification (0.138" / 3.50mm)
• Number of rows (2)
• Mounting configuration (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Holder)
• Color (Black)
• Sealed feature requirement
• Series designation (MX150 33472)

The Molex 0334722006 meets all these parameters and is therefore classified as a parametric equivalent. Differences in packaging format (Bulk versus standard), insulation material composition, operating temperature specification, and compliance certifications do not affect the core functional and mechanical compatibility of the housing component.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0334722303 and Molex 0334722006 are Active product status components within the MX150 33472 series. Selection between these parts is based on application requirements and supply chain considerations:

Molex 0334722303 is suitable for applications where standard packaging and the specified insulation material composition (Syndiotactic Polystyrene, Glass Filled) are required.

Molex 0334722006 is suitable for applications where bulk packaging is preferred and the alternative insulation material composition (Polyamide/Nylon, Glass Filled with Syndiotactic Polystyrene) is acceptable. This part carries RoHS3 compliance certification and REACH Unaffected status, with defined operating temperature range (-40°C to 150°C) and MSL rating of 1 (Unlimited).

Both parts are classified under ECCN EAR99 and share identical core connector specifications. The choice between them does not affect electrical or mechanical compatibility within the MX150 33472 series ecosystem.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334722006 be used as a direct replacement for the Molex 0334722303?

A: Yes. Both parts are parametric equivalents with identical connector type, contact configuration, position count, pitch, row arrangement, mounting type, termination method, and fastening mechanism. They are mechanically and electrically interchangeable within the MX150 33472 series.

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

A: The primary differences are packaging format (standard versus bulk), insulation material composition, operating temperature specification, and compliance certifications. The 0334722006 includes RoHS3 compliance and REACH Unaffected status with a defined operating temperature range of -40°C to 150°C and MSL rating of 1.

Q: Does the insulation material difference affect compatibility?

A: No. Both insulation materials (Syndiotactic Polystyrene and Polyamide/Nylon, both glass-filled) are suitable for the sealed receptacle housing application. The material difference does not impact mechanical fit, electrical performance, or connector interface compatibility.

Q: Are contacts included with either part?

A: No. Both the 0334722303 and 0334722006 are housing components only. Contacts must be sourced separately and are not included with either part.

Q: Which part should be selected for new designs?

A: Selection depends on specific design requirements. If RoHS3 compliance and defined operating temperature specifications are required, the 0334722006 is appropriate. If standard packaging and the original insulation material specification are required, the 0334722303 is appropriate. Both are Active status products suitable for new designs.

Q: Can these parts be mixed in the same assembly?

A: Yes. Since both parts are parametric equivalents with identical core specifications, they can be used interchangeably within the same assembly without affecting form, fit, or function.
