Equivalent & Substitute Parts for Molex 0334721379

Part Overview

The Molex 0334721379 is a 12-position rectangular connector receptacle housing designed for the MX150 33472 series. This component functions as a housing for female socket contacts with a 0.138" (3.50mm) pitch configuration, supporting two-row arrangements in free-hanging inline mounting applications. The part maintains Active product status and is currently in stock with 702 units available. Alternative equivalent parts may be required due to color specification requirements, insulation material preferences, or operational temperature range considerations in specific application environments.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334721379 is determined by strict equivalence across the following critical parameters:

• Connector Type: Must be Receptacle
• Contact Type: Must be Female Socket
• Number of Positions: Must be 12
• Pitch: Must be 0.138" (3.50mm)
• Number of Rows: Must be 2
• Mounting Type: Must be Free Hanging (In-Line)
• Contact Termination: Must be Crimp
• Fastening Type: Must be Latch Holder
• Features: Must be Sealed
• Series: Must be MX150 33472

The substitute part 0334721207 meets all critical electrical and mechanical parameters required for functional equivalence. Variations in color, insulation material composition, and operating temperature range do not affect the core substitution relationship when these parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0334721379 and 0334721207 maintain Active product status and are manufactured by Molex within the MX150 33472 series. The 0334721207 substitute part carries ROHS3 compliance certification and REACH Unaffected status, providing additional regulatory documentation for applications requiring these certifications. The main part 0334721379 does not specify these compliance statuses in the provided data.

The substitute part 0334721207 includes an operating temperature range specification of -40°C to 150°C, whereas the main part does not provide this parameter. Selection between these parts should be based on specific application requirements regarding color specification, insulation material composition, and regulatory compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334721207 directly replace the 0334721379 in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters including connector type, contact type, position count, pitch, row configuration, mounting type, termination method, and fastening mechanism. The parts are functionally equivalent within the MX150 33472 series.

Q: What are the differences between these two parts?

A: The primary differences are color (Black versus Gray), insulation material composition (SPS Glass Filled versus PA/Nylon Glass Filled with SPS), and documented operating temperature range. The 0334721207 includes ROHS3 compliance and REACH Unaffected certifications.

Q: Does the color difference affect electrical performance?

A: No. Color is a cosmetic specification that does not affect electrical or mechanical performance. Selection should be based on application requirements and design specifications.

Q: Are contacts included with either part?

A: No. Both the 0334721379 and 0334721207 are housings only. Contacts must be sourced separately and are not included with these parts.

Q: What packaging formats are available?

A: The 0334721379 is available in standard packaging, while the 0334721207 is supplied in Bulk packaging. Packaging format selection depends on procurement volume and inventory management requirements.

Q: Which part should be selected for applications requiring regulatory compliance documentation?

A: The 0334721207 provides documented ROHS3 compliance and REACH Unaffected status. Applications requiring these certifications should specify the 0334721207 part number.
