Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0934444209 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with male pin contacts
• Position Count & Row Configuration: 6 positions arranged in 2 rows
• Mounting & Termination: Free-hanging inline mounting with crimp contact termination
• Electrical & Mechanical Compatibility: Contact pitch, row spacing, and fastening mechanism must accommodate existing mated connectors and PCB layouts
• Environmental & Compliance Requirements: IP68 rating and ROHS3 compliance

The TE Connectivity Deutsch Connectors 776434-3 (AMPSEAL 16 series) meets these core substitution criteria as a 6-position, 2-row receptacle housing with crimp termination and free-hanging inline mounting. Both parts are ROHS3 compliant and support equivalent electrical and mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Deutsch Connectors 776434-3 is an active-status substitute for the obsolete Molex 0934444209. Both components maintain ROHS3 compliance and support equivalent functional requirements for 6-position, 2-row receptacle housings with crimp termination and free-hanging inline mounting.

Selection of the substitute part is supported by:

• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts meet ROHS3 requirements
• Functional Equivalence: Matching connector type, position count, row configuration, mounting method, and termination technology
• Inventory Availability: The substitute part maintains substantial stock levels (3226 pcs), supporting immediate procurement

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting the Molex 0934444209?

A: The substitute must be a 6-position, 2-row receptacle housing with male pin contacts, crimp termination, free-hanging inline mounting, and latch-type fastening. Both connector type and position configuration are non-negotiable for mechanical and electrical compatibility.

Q: Does the color difference between red (original) and black (substitute) affect compatibility?

A: Color is a visual identifier and does not affect electrical or mechanical compatibility. The substitute's black color is a cosmetic difference only.

Q: Are contacts included with either housing?

A: No. Both the Molex 0934444209 and TE Connectivity 776434-3 are housings only. Contacts must be procured separately and are not included.

Q: What is the significance of the pitch and row spacing specifications for the substitute?

A: The TE Connectivity 776434-3 specifies a pitch of 0.177" (4.50mm) and row spacing of 0.209" (5.30mm). These dimensions define the physical layout of contact positions and must be compatible with existing mated connectors and PCB designs. The original part's pitch and row spacing are not specified in available documentation.

Q: Why is the substitute part's MSL rating different?

A: The Molex 0934444209 lists MSL as Not Applicable, while the TE Connectivity 776434-3 specifies MSL 1 (Unlimited). MSL ratings apply to moisture sensitivity during storage and handling. The substitute's MSL 1 rating indicates minimal moisture sensitivity and unlimited shelf life under standard conditions.

Q: Is the substitute available in the same red color as the original?

A: The provided substitute is available in black only. If color matching is a design requirement, additional substitute options should be evaluated.
