Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0442480009 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Unshielded
• Number of Ports: 2
• Number of Rows: 1
• Operating Temperature Range: -40°C ~ 85°C
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Tab Direction: Up

Allowable Variation:

• Number of Positions/Contacts: The substitute part may support a subset of the original contact configuration (6p4c instead of 6p6c) provided the substitute maintains compatibility with the primary RJ11 and RJ14 standards supported by the original part.

The TE Connectivity AMP Connectors part 1734479-4 meets all mandatory parameters and represents a valid substitute for applications utilizing 6-position, 4-contact (6p4c) configurations within the RJ11 and RJ14 standards.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1734479-4 is the designated substitute for the obsolete Molex 0442480009. Selection of this alternative is supported by the following factors:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance, ensuring adherence to current environmental and hazardous substance restrictions. The TE Connectivity part carries active product status, providing assured long-term availability and supply chain stability compared to the obsolete Molex component.

Functional Equivalence: The substitute part maintains all critical electrical and mechanical parameters including connector type, mounting configuration, orientation, termination method, shielding characteristics, and operating temperature range. Contact material, finish specification, and finish thickness are identical.

Configuration Consideration: The TE Connectivity 1734479-4 operates as a 6p4c (6-position, 4-contact) jack, supporting RJ11 and RJ14 standards. Applications requiring the full 6p6c configuration (RJ12 and RJ25 support) must evaluate whether the reduced contact count aligns with system requirements. For RJ11 and RJ14 applications, the 6p4c configuration provides full functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1734479-4 directly replace the Molex 0442480009 in all applications?

A: The TE Connectivity part is a direct substitute for applications using RJ11 or RJ14 standards. Applications requiring RJ12 or RJ25 support (which utilize the full 6-contact configuration) must confirm that the 6p4c contact count meets system specifications.

Q: What is the difference between 6p6c and 6p4c contact configurations?

A: The notation indicates position count and contact count. 6p6c denotes 6 positions with 6 contacts populated; 6p4c denotes 6 positions with 4 contacts populated. The TE Connectivity part supports the four contacts required for RJ11 and RJ14 applications.

Q: Are the physical dimensions and PCB footprints identical between these parts?

A: Both parts share identical mounting type (through hole), orientation (90° right angle), and tab direction (up). Physical compatibility is maintained for PCB layout purposes.

Q: What is the inventory status for each part?

A: The Molex 0442480009 has 1041 pieces in stock as new original inventory. The TE Connectivity 1734479-4 has 1841 pieces in stock. The TE Connectivity part carries active product status, ensuring continued availability.

Q: Are there any differences in housing material between these connectors?

A: The Molex part uses Polybutylene Terephthalate (PBT) with polyester and glass filler. The TE Connectivity part uses Polyamide (PA46) nylon 4/6 with glass filler. Both materials provide suitable mechanical and thermal properties for the specified operating temperature range.

Q: What certifications apply to both parts?

A: Both parts are ROHS3 compliant. The Molex part carries REACH Unaffected status. The TE Connectivity part lists REACH status as vendor undefined. Both parts carry EAR99 ECCN classification and 8536.69.4040 HTSUS code.
