Molex 0334722305 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334722305 is a 20-position rectangular connector receptacle housing designed for the MX150 33472 series. This component functions as a female socket housing with a 0.138" (3.50mm) pitch configuration, featuring a sealed design with crimp-type contact termination and latch holder fastening. The part is currently in active product status with 1183 pieces available in new original inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across alternative part numbers, enabling component interchangeability in applications where the original part number becomes unavailable or when bulk packaging alternatives are required.

Substitute Part Grouping Explanation

Substitute part identification for the Molex 0334722305 is based on strict equivalence of the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 20 positions at 0.138" (3.50mm) spacing
Row Configuration: 2-row arrangement
Termination & Fastening: Crimp contact termination with latch holder fastening
Physical Characteristics: Black color, sealed design, free hanging in-line mounting
Series Compatibility: MX150 33472 series designation

The substitute part Molex 0334722006 maintains all critical electrical and mechanical parameters required for direct substitution. Variations in packaging type (bulk versus standard), insulation material composition, operating temperature range, and compliance certifications do not affect the core functional interchangeability of the connector housing itself.

Engineering Selection Recommendations

Both the Molex 0334722305 and 0334722006 are active products within the MX150 33472 connector series and maintain identical core specifications for connector housing functionality. Selection between these parts should be based on the following criteria:

Molex 0334722305 is specified when standard packaging requirements are in place and the original part number designation must be maintained in design documentation or procurement systems.

Molex 0334722006 is specified when bulk packaging is acceptable for manufacturing operations or when higher inventory availability is required. This part carries RoHS3 compliance certification and REACH unaffected status, providing additional regulatory documentation for applications subject to these requirements. The operating temperature range of -40°C to 150°C is explicitly defined for this variant.

Both parts are suitable for direct substitution in applications requiring a 20-position, 3.50mm pitch rectangular connector receptacle housing with sealed, crimp-terminated female socket contacts. The choice between them does not affect electrical or mechanical performance in the connector interface.

Frequently Asked Questions (FAQ)

Q: Can Molex 0334722006 be used as a direct replacement for Molex 0334722305?

A: Yes. Both parts are functionally equivalent rectangular connector housings with identical connector type, position count, pitch, row configuration, mounting type, contact termination, and fastening specifications. The parts are interchangeable at the housing level.

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

A: The primary differences are packaging type (0334722305 uses standard packaging; 0334722006 uses bulk packaging), insulation material composition (0334722305 specifies Syndiotactic Polystyrene glass-filled; 0334722006 specifies Polyamide nylon glass-filled with Syndiotactic Polystyrene), and documented operating temperature range (0334722006 specifies -40°C to 150°C). Both parts maintain identical connector housing specifications.

Q: Are contacts included with these connector housings?

A: No. Both part numbers are connector housings only. Contacts are not included and must be sourced separately. Ensure that replacement contacts are compatible with the crimp termination specification and the 20-position, 2-row configuration.

Q: What compliance certifications apply to these parts?

A: Molex 0334722305 carries EAR99 export classification. Molex 0334722006 carries EAR99 export classification, RoHS3 compliance certification, and REACH unaffected status. Applications requiring specific regulatory compliance should reference the appropriate part number documentation.

Q: Can these housings be used in sealed applications?

A: Yes. Both parts feature sealed design characteristics, making them suitable for applications requiring environmental protection. Verify that mating connector plugs and contacts also meet sealed specifications for complete system integrity.

Q: What is the inventory status for these parts?

A: Molex 0334722305 has 1183 pieces in new original stock. Molex 0334722006 has 1624 pieces in new original stock. Both parts are currently available for procurement.
