Molex 0334721344 Rectangular Connector Housing – Equivalent & Substitute Parts

Part Overview

The Molex 0334721344 is a 12-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, supporting crimp-terminated contacts in a 2-row arrangement. The housing features sealed construction with a black insulation material composition.

This part is classified as Active product status with 1,037 units currently in stock. Identifying equivalent substitute parts is necessary to ensure supply chain continuity, accommodate design revisions, or address specific application requirements such as color specification, material composition, or compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334721344 are identified based on strict parametric equivalence within the MX150 33472 connector series. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 12
• 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

Variable Parameters (Non-Critical for Substitution):

• Color (Black vs. Gray)
• Insulation Material composition
• Operating Temperature range
• Packaging format
• Compliance certifications

The substitute part Molex 0334721207 maintains complete parametric alignment across all critical dimensions and functional characteristics, differing only in color specification, material composition, and compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0334721344 and Molex 0334721207 are Active product status components within the MX150 33472 series, confirming ongoing manufacturer support and availability.

Selection Criteria Based on Provided Specifications:

The Molex 0334721207 substitute part provides additional compliance documentation, including ROHS3 certification and REACH Unaffected status, which may be required for applications subject to environmental regulations. The substitute part also specifies an operating temperature range of -40°C to 150°C, whereas the main part does not provide this specification.

Material composition differs between the two parts: the main part uses Syndiotactic Polystyrene (SPS) with glass filling, while the substitute incorporates Polyamide (PA) nylon with glass filling in addition to SPS. This material variation may influence mechanical properties and environmental resistance characteristics.

Color differentiation (Black vs. Gray) represents a cosmetic distinction with no functional impact on electrical or mechanical performance within the connector series.

The substitute part is available in Bulk packaging with significantly higher inventory (4,771 units) compared to the main part (1,037 units), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334721207 directly replace the Molex 0334721344 in existing designs?

A: Yes. Both parts maintain identical parametric specifications across connector type, contact configuration, pitch, position count, row arrangement, mounting method, termination type, and fastening mechanism. The parts are functionally interchangeable within the MX150 33472 series.

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

A: Color specification (Black vs. Gray) is a cosmetic attribute with no impact on electrical performance, mechanical compatibility, or functional operation. Selection between colors is determined by application aesthetics or design documentation requirements only.

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

A: The main part (0334721344) uses Syndiotactic Polystyrene (SPS) with glass filling. The substitute part (0334721207) incorporates both Polyamide (PA) nylon and Syndiotactic Polystyrene (SPS), both with glass filling. Material composition may influence mechanical properties, chemical resistance, and thermal characteristics, though both formulations support the sealed connector design.

Q: Does the operating temperature specification affect substitution eligibility?

A: The main part does not specify an operating temperature range. The substitute part specifies -40°C to 150°C. This specification difference does not prevent substitution; however, applications requiring confirmed temperature performance should reference the substitute part's documented range.

Q: What packaging formats are available for these parts?

A: The main part (0334721344) is available in standard packaging with 1,037 units in stock. The substitute part (0334721207) is available in Bulk packaging with 4,771 units in stock. Packaging format selection depends on procurement volume requirements and inventory management practices.

Q: Are there compliance or certification differences between these parts?

A: The substitute part (0334721207) includes ROHS3 compliance certification and REACH Unaffected status documentation. The main part does not specify these certifications. Applications subject to environmental or regulatory compliance requirements should reference the substitute part's documented certifications.

Q: What is the Moisture Sensitivity Level (MSL) difference?

A: The main part lists MSL as Not Applicable. The substitute part specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This difference does not affect substitution eligibility for standard applications.
