Molex 0334721528 Rectangular Connector Housing – Equivalent & Substitute Parts

Part Overview

The Molex 0334721528 is a 12-position receptacle housing for rectangular connectors, designed for applications requiring sealed, free-hanging inline connections with a 0.138" (3.50mm) pitch. This component is part of the MX150 33472 series and maintains Active product status. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector housing category, enabling design flexibility and supply chain optimization without compromising functional performance.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334721528 are identified based on strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 12 positions at 0.138" (3.50mm) pitch
• Mechanical Interface: 2-row configuration with free-hanging inline mounting
• Termination & Fastening: Crimp contact termination with latch holder fastening
• Environmental Sealing: Sealed housing design

The substitute part Molex 0334721207 maintains all core electrical and mechanical parameters required for direct functional equivalence within the MX150 33472 series. Variations in insulation material composition and color do not affect connector interchangeability when mating with standard MX150 series contacts and compatible connector plugs.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0334721528 and 0334721207 are Active product status components within the MX150 33472 series, confirming ongoing manufacturer support and availability. The substitute part 0334721207 provides documented compliance certifications including ROHS3 and REACH Unaffected status, with defined operating temperature range of -40°C to 150°C. Selection between these parts should be based on application-specific requirements for insulation material properties, color coding for assembly or identification purposes, and regulatory compliance mandates. Both parts are functionally equivalent for standard MX150 series mating applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334721207 directly replace the 0334721528 in existing designs?

A: Yes. Both parts maintain identical electrical and mechanical parameters across connector type, position count, pitch, mounting configuration, and fastening method. They are functionally interchangeable within MX150 33472 series applications.

Q: What is the significance of the color difference between these parts?

A: Color variation (Black vs. Gray) is a cosmetic and identification feature only. It does not affect electrical performance, mechanical fit, or mating compatibility with standard MX150 series contacts and plugs.

Q: How do the insulation materials differ between these parts?

A: The 0334721528 uses Syndiotactic Polystyrene (SPS) with glass fill, while the 0334721207 combines Polyamide (PA) Nylon with glass fill and Syndiotactic Polystyrene (SPS). Both materials are suitable for sealed connector housing applications. Material selection should align with specific environmental and chemical exposure requirements of the end application.

Q: Does the substitute part have better compliance documentation?

A: The 0334721207 includes explicit ROHS3 Compliant and REACH Unaffected certifications with defined operating temperature range (-40°C to 150°C) and MSL rating (1 – Unlimited). These specifications support regulatory compliance verification for applications with specific environmental or regional requirements.

Q: Are contacts included with either housing?

A: No. Both the 0334721528 and 0334721207 are housings only. Contacts must be sourced separately and are not included with these components.

Q: What packaging formats are available?

A: The 0334721528 is supplied in standard packaging, while the 0334721207 is available in Bulk packaging format. Packaging selection should be based on procurement volume and inventory management requirements.
