Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0334720604 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Electrical Interface: 6-position layout with 0.138" (4.60mm) pitch and 2-row configuration
• Mechanical Interface: Free-hanging inline mounting with crimp termination and latch holder fastening
• Environmental Compliance: Moisture sensitivity level and operating temperature range

The primary manufacturer-recommended substitute is Molex 0334720669, which maintains identical electrical and mechanical interfaces while offering improved material specifications and extended operating temperature capability. This part is classified as active, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0334720669 is the manufacturer-recommended substitute for the obsolete 0334720604. Selection of this substitute is justified on the following basis:

Product Status & Availability: The original part is obsolete, while the substitute maintains active status with confirmed inventory availability (1326 pcs in stock), ensuring supply chain continuity.

Electrical & Mechanical Compatibility: Both parts share identical connector type, contact configuration, pitch, row layout, mounting method, and termination approach. Direct mechanical and electrical interchangeability is established.

Environmental & Compliance Improvements: The substitute offers an extended operating temperature range (-40°C to 150°C versus -40°C to 125°C) and meets ROHS3 and REACH compliance standards, providing enhanced regulatory alignment for current manufacturing requirements.

Material Enhancement: The substitute utilizes polyamide (PA) nylon with glass filling and syndiotatic polystyrene (SPS), providing improved material durability compared to the original polyester insulation.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334720669 be used as a direct replacement for the 0334720604 in existing designs?

A: Yes. Both parts maintain identical electrical and mechanical interfaces: 6-position receptacle housing, 0.138" (4.60mm) pitch, 2-row configuration, crimp termination, and latch holder fastening. Physical and functional interchangeability is established.

Q: What is the significance of the color difference between the original (green) and substitute (gray) parts?

A: Color is a visual identifier only and does not affect electrical or mechanical function. The color change reflects the material composition difference (polyester to polyamide/nylon blend) but does not impact connector performance or compatibility.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: No. The substitute's extended range (-40°C to 150°C) is a performance enhancement that maintains full compatibility with applications designed for the original range (-40°C to 125°C). The substitute operates safely across both temperature specifications.

Q: Are contacts included with either part?

A: No. Both the original and substitute parts are housings only. Contacts must be sourced separately and are not included with either part number.

Q: What is the significance of ROHS3 and REACH compliance on the substitute part?

A: These certifications indicate compliance with current European environmental and chemical safety regulations. For designs requiring regulatory compliance with modern standards, the substitute part provides documented certification status, whereas the original part does not specify these certifications.

Q: Is the substitute part available in the same packaging as the original?

A: The substitute is supplied in bulk packaging, whereas the original packaging specification is not provided. Confirm packaging requirements with your procurement process.
