Molex 0334820621 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334820621 is a 6-position rectangular connector plug housing with 4.60mm pitch, designed for crimp contact termination in free-hanging inline applications. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance requirements. The sealed design with locking ramp fastening provides reliable connection in industrial applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334820621 are qualified based on the following critical parameters that determine functional interchangeability:

Core Electrical & Mechanical Criteria:

• Connector Type: Plug
• Number of Positions: 6
• Pitch: 0.138" (4.60mm)
• Number of Rows: 2
• Contact Type: Male Blade
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Features: Sealed
• Series: MX150 33482

Compliance & Environmental Criteria:

• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The substitute parts 0334823621, 0334823601, and 0334823602 maintain all critical electrical and mechanical parameters. Variations in color (Black vs. Gray) and insulation material composition do not affect functional interchangeability in standard applications. The transition from obsolete to active product status ensures long-term supply availability.

Engineering Selection Recommendations

Primary Recommendation: Molex 0334823621

The 0334823621 is the direct successor to the obsolete 0334820621, maintaining identical black color and all electrical and mechanical specifications. This part is currently in active production status with ROHS3 compliance and unlimited MSL rating, ensuring long-term availability and supply chain stability.

Secondary Recommendations: Molex 0334823601 and 0334823602

Both 0334823601 and 0334823602 are parametric equivalents with identical electrical and mechanical characteristics. The primary distinction is color (Gray vs. Black). These parts are active production items with ROHS3 compliance and unlimited MSL rating. Selection between these alternatives depends on application-specific color requirements or inventory availability.

All three substitute parts are qualified for direct replacement based on maintained compliance certifications and identical functional parameters.

Frequently Asked Questions (FAQ)

Q: Can the 0334823601 or 0334823602 be used as direct replacements for the 0334820621?

A: Yes. Both parts maintain identical electrical and mechanical specifications including connector type, position count, pitch, contact type, mounting configuration, and fastening mechanism. The color difference (Gray vs. Black) does not affect electrical performance or mechanical interchangeability.

Q: What is the primary reason for substitution?

A: The 0334820621 is classified as obsolete. The substitute parts 0334823621, 0334823601, and 0334823602 are active production items, ensuring continued availability for new designs and maintenance applications.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All parts maintain ROHS3 compliance and MSL rating 1 (Unlimited). No additional qualification or testing is required for substitution.

Q: Does packaging affect interchangeability?

A: No. Packaging format (bulk vs. standard) does not affect the connector housing specifications or performance. Selection is based on procurement and inventory requirements.

Q: Which substitute should be selected for new designs?

A: The 0334823621 is recommended for new designs as it maintains the original black color specification. The 0334823601 and 0334823602 are suitable alternatives if color variation is acceptable or if inventory availability favors their selection.
