Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 1731070367 is constrained by the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub, Combo
• Connector Type: Receptacle for Female Contacts
• Number of Positions: 5 (Coax or Power)
• Shell Size, Connector Layout: 3 (DB, B) - 5W5
• Contact Type: Coax or Power
• Dielectric Material: Polyester, Glass Filled
• Operating Temperature Range: -55°C ~ 130°C

Allowable Variations:

• Mounting Type: Panel Mount (main part) vs. Free Hanging (In-Line) for substitute
• Termination: Solder Cup (main part) vs. Housing Only (substitute)
• Shell Material Finish: Steel (main part) vs. Steel, Tin Plated (substitute)
• Product Status: Obsolete (main part) vs. Active (substitute)

The substitute part 1727040034 maintains electrical and mechanical compatibility through identical connector geometry, contact configuration, and environmental specifications, while differing in mounting approach and termination method.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1727040034 serves as a functional substitute for the obsolete 1731070367 based on the following engineering criteria:

Electrical Compatibility: Both connectors maintain identical contact configuration, shell geometry (5W5 layout), and environmental operating specifications (-55°C to 130°C). The dielectric material and contact type are identical, ensuring electrical performance equivalence.

Mechanical Compatibility: Shell size, connector layout, and flange design are identical. Both feature unthreaded housing/shell flanges and green polyester glass-filled dielectric material.

Regulatory Compliance: Both parts carry EAR99 classification and MSL Level 1 (Unlimited) moisture sensitivity rating, indicating equivalent handling and storage requirements.

Availability Advantage: The substitute part 1727040034 is currently Active in production with 2,839 units in stock, compared to the obsolete status of the main part with limited remaining inventory.

Functional Difference: The primary distinction is mounting configuration. The main part (1731070367) is panel mount with integrated solder cup termination, while the substitute (1727040034) is a free-hanging housing receptacle without integrated contacts. This difference requires assessment of the specific application's mounting and termination requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1727040034 directly replace the 1731070367 in all applications?

A: Direct replacement depends on mounting and termination requirements. The 1731070367 is panel mount with solder cup termination, while the 1727040034 is a free-hanging housing receptacle. If your application requires panel mounting with solder cup termination, the 1727040034 housing must be paired with appropriate mounting hardware and contacts. If your application uses in-line free-hanging configuration, the 1727040034 is directly compatible.

Q: What are the critical parameters that must match for substitution?

A: Connector style (D-Sub, Combo), connector type (receptacle for female contacts), number of positions (5), shell size and layout (3/5W5), contact type (coax or power), and operating temperature range (-55°C to 130°C) must remain identical. These parameters define mechanical and electrical mating compatibility.

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

A: Both parts carry identical regulatory classifications: EAR99 export control, MSL Level 1 (Unlimited) moisture sensitivity, and UL94 V-0 flammability rating for the main part. The substitute part is RoHS3 Compliant and REACH Unaffected, providing additional regulatory alignment for new designs.

Q: What is the significance of the shell material finish difference?

A: The main part features steel shell material, while the substitute features steel with tin plating. Tin plating provides enhanced corrosion resistance and improved solderability. This difference is allowable for substitution as both materials maintain the same mechanical and electrical properties required for the 5W5 connector layout.

Q: How should I handle the termination difference in my design?

A: The 1731070367 includes integrated solder cup termination for direct PCB soldering. The 1727040034 is a housing-only receptacle without integrated contacts or termination. If substituting, you must source compatible female contacts separately and use appropriate mounting hardware for your specific application (panel mount or in-line configuration).
