Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334820651 is determined by strict equivalence across the following critical parameters:

• Connector type (Plug)
• Number of positions (6)
• Pitch specification (0.138" / 4.60mm)
• Number of rows (2)
• Contact type (Male Blade)
• Contact termination method (Crimp)
• Fastening mechanism (Locking Ramp)
• Mounting configuration (Free Hanging In-Line)
• Color (Black)
• RoHS compliance status (ROHS3)
• MSL rating (1)

The direct substitute Molex 0334823651 maintains full equivalence across all these parameters while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0334823651 is the direct functional equivalent to the obsolete 0334820651. Both components maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product lifecycle status: 0334823651 is actively manufactured and stocked, while 0334820651 is obsolete.

For new designs and ongoing production, the 0334823651 should be specified. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with current environmental and regulatory requirements. The substitute part is available in current inventory (722 pcs) and supports the same crimp contact termination and locking ramp fastening architecture.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334823651 directly replace the 0334820651 in existing assemblies?

A: Yes. The 0334823651 maintains full electrical and mechanical equivalence across all specified parameters, including connector type, position count, pitch, row configuration, contact type, termination method, and fastening mechanism. Direct substitution is supported without design modification.

Q: What is the significance of the product status difference between these parts?

A: The 0334820651 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 0334823651 is active production status with current manufacturing support and inventory availability. For ongoing procurement, the active part number should be specified.

Q: Are there compatibility considerations with existing contact sets?

A: Both housings accept crimp-terminated male blade contacts designed for the MX150 33482 series with 4.60mm pitch. Contact compatibility is determined by series designation and pitch specification, which are identical between the main part and substitute.

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both the 0334820651 and 0334823651 are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level), supporting equivalent performance in regulated applications.

Q: What is the difference in insulation material specifications?

A: The 0334823651 specifies insulation material composition (Polyamide PA, Nylon, Glass Filled; Syndiotatic Polystyrene SPS) and operating temperature range (-40°C to 150°C). These specifications are provided for the substitute part and represent the material and thermal characteristics of the active equivalent.
