Molex 0334823621 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334823621 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 part of the MX150 33482 series and is actively manufactured. Substitute parts may be required due to inventory availability, packaging preferences, or specific color requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334823621 are determined by equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Plug housing with male blade contacts
• Electrical Interface: 6 positions at 0.138" (4.60mm) pitch in 2-row configuration
• Mechanical Interface: Free-hanging inline mounting with crimp termination and locking ramp fastening
• Environmental Compliance: ROHS3 compliance, MSL 1 rating, and -40°C to 150°C operating range
• Material & Sealing: Polyamide/Nylon glass-filled insulation with sealed features

The substitute parts 0334823601 and 0334823602 maintain identical electrical and mechanical specifications. Variations are limited to housing color (gray versus black) and packaging format (bulk versus standard), which do not affect functional compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0334823621, 0334823601, and 0334823602—are active products manufactured by Molex and carry identical ROHS3 compliance and MSL 1 ratings. Selection between these parts should be based on:

Color Requirement: The 0334823621 features black housing, while 0334823601 and 0334823602 provide gray housing alternatives. Housing color does not affect electrical performance or mechanical compatibility.

Packaging & Availability: The 0334823621 is supplied in standard packaging with 937 units in stock. Substitutes 0334823601 and 0334823602 are available in bulk packaging with higher inventory levels (6343 and 7808 units respectively), offering supply chain flexibility.

Compliance & Environmental Rating: All three parts meet identical environmental and regulatory requirements, including ROHS3 compliance, unlimited moisture sensitivity tolerance, and full operational capability across the -40°C to 150°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can 0334823601 or 0334823602 be used as direct replacements for 0334823621?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications, including connector type, contact configuration, pitch, mounting method, and termination type. The only differences are housing color and packaging format.

Q: Does housing color affect connector performance or compatibility?

A: No. Housing color is a cosmetic specification and does not impact electrical performance, mechanical fit, or functional compatibility with mating connectors or contact sets.

Q: Are there any differences in contact compatibility between these parts?

A: No. All three parts use identical male blade contact types and crimp termination specifications. Contacts designed for the 0334823621 are fully compatible with 0334823601 and 0334823602.

Q: What is the significance of the different packaging formats?

A: The 0334823621 uses standard packaging, while 0334823601 and 0334823602 use bulk packaging. Packaging format affects handling and storage but does not influence component performance or specifications.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 0334823621, 0334823601, and 0334823602 are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings.

Q: Can these connectors be used in the same assembly without modification?

A: Yes. All three parts are mechanically and electrically interchangeable within the same assembly design. No design modifications are required for substitution.
