Molex 0334722320 Rectangular Connector Housing – Equivalent & Substitute Parts

Part Overview

The Molex 0334722320 is a 20-position rectangular connector receptacle housing designed for the MX150 33472 series. This component serves as the female socket housing in applications requiring crimp-terminated connections with a 0.138" (3.50mm) pitch configuration. The part is classified as Active and maintains 807 units in current inventory stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector housings within the same series, allowing for interchangeability in applications where housing color or insulation material variations are acceptable within design specifications.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334722320 are identified based on strict equivalence across the following critical parameters:

• Connector Type: Receptacle housing
• Contact Type: Female Socket
• Number of Positions: 20
• Pitch: 0.138" (3.50mm)
• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Features: Sealed
• Series: MX150 33472

The substitute part Molex 0334722006 maintains all critical electrical and mechanical parameters. Variations in housing color (Gray versus Black) and insulation material composition do not affect functional interchangeability when both materials meet the application's environmental and performance requirements. Both parts are classified as Active products within the same manufacturer series.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0334722320 and 0334722006 are Active products within the MX150 33472 series, confirming ongoing manufacturer support and availability. The substitute part 0334722006 offers higher inventory availability at 1624 units compared to 807 units for the main part.

The 0334722006 provides additional compliance documentation, including RoHS3 compliance and REACH Unaffected status, along with specified operating temperature range of -40°C to 150°C and MSL rating of 1 (Unlimited). These certifications support applications requiring regulatory compliance documentation.

Selection between these parts should be based on application-specific requirements regarding housing color, insulation material properties, and compliance documentation needs. Both parts maintain identical electrical and mechanical interface specifications within the MX150 33472 series.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334722006 be used as a direct replacement for the 0334722320?

A: Yes. Both parts maintain identical connector type, contact configuration, pitch, row count, mounting method, termination type, and fastening mechanism. The parts are functionally interchangeable in applications where housing color and insulation material variations are acceptable.

Q: What is the difference between the Gray and Black housing versions?

A: The primary difference is housing color. The 0334722320 features Gray housing with Syndiotactic Polystyrene (SPS) glass-filled insulation. The 0334722006 features Black housing with Polyamide (PA) Nylon glass-filled and Syndiotactic Polystyrene (SPS) insulation materials. Both maintain sealed construction and identical electrical specifications.

Q: Are contacts included with these connector housings?

A: No. Both the 0334722320 and 0334722006 are housing components only. Contacts must be sourced separately and crimped into the housing according to Molex specifications.

Q: What is the significance of the MSL rating difference?

A: The 0334722320 lists MSL as Not Applicable, while the 0334722006 specifies MSL 1 (Unlimited). MSL 1 indicates the component has unlimited shelf life under standard storage conditions. This difference does not affect functional interchangeability but may influence storage and handling protocols in moisture-sensitive manufacturing environments.

Q: Which part should be selected for new designs?

A: Both parts are Active and suitable for new designs. The 0334722006 offers higher inventory availability and documented compliance certifications (RoHS3, REACH status, operating temperature range). Selection should align with design requirements for housing color, material properties, and regulatory compliance documentation.

Q: Are these parts compatible with other MX150 series components?

A: Yes. Both housings are part of the MX150 33472 series and maintain compatibility with other components within this series that share the 0.138" (3.50mm) pitch and 20-position configuration specifications.
