Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334820643 are qualified based on the following critical parameters that determine functional interchangeability:

• Connector Type: Plug
• Contact Type: Male Blade
• Number of Positions: 6
• Pitch: 0.138" (4.60mm)
• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Series: MX150 33482
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary substitute identified is Molex 0334823643, which maintains all critical electrical and mechanical parameters. Secondary substitutes (0334823601, 0334823602) are also qualified under the same parameter set. Variations in color and insulation material do not affect functional compatibility when these core parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0334823643 is the primary recommended substitute for the obsolete 0334820643. Both components are ROHS3 compliant and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: 0334823643 is active and currently in production, ensuring long-term availability and supply chain continuity.

Secondary substitutes 0334823601 and 0334823602 are also qualified alternatives within the MX150 33482 series, maintaining full parameter compatibility. Selection among these options should be based on current inventory availability and procurement lead times.

All substitute parts are suitable for direct replacement in existing designs without modification to PCB layouts, mating connectors, or contact specifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334823643 be used as a direct replacement for the 0334820643?

A: Yes. Both components share identical specifications for connector type, contact type, position count, pitch, row configuration, mounting type, termination method, and fastening mechanism. The primary difference is product status and color, neither of which affects functional compatibility.

Q: What is the significance of the product status change from Obsolete to Active?

A: The active status of 0334823643 indicates current manufacturing and availability through standard distribution channels. This ensures reliable procurement for new production runs and field replacements without extended lead times or supply constraints.

Q: Are the secondary substitutes 0334823601 and 0334823602 equivalent to the primary substitute?

A: Yes. All three substitute part numbers (0334823643, 0334823601, 0334823602) maintain identical electrical and mechanical parameters within the MX150 33482 series. Selection should be based on inventory availability and delivery requirements.

Q: Does the color difference between the black 0334820643 and gray 0334823643 affect compatibility?

A: No. Color is a cosmetic attribute that does not impact electrical performance, mechanical fit, or functional interchangeability. Both housings maintain identical dimensional and contact specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The main part and all identified substitutes are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current environmental and regulatory requirements.

Q: What parameters must remain constant for a part to be considered a valid substitute?

A: Valid substitutes must maintain: connector type (Plug), contact type (Male Blade), position count (6), pitch (4.60mm), row configuration (2 rows), mounting type (Free Hanging In-Line), termination method (Crimp), fastening type (Locking Ramp), and series designation (MX150 33482).
