Molex 0334822321 Rectangular Connector Plug Housing – Equivalent & Substitute Parts

Part Overview

The Molex 0334822321 is a 20-position rectangular connector plug housing from the MX150 33482 series. This component is a black, sealed plug housing designed for male blade contacts with a 0.138" (3.50mm) pitch configuration. The part is currently active in production and available in inventory.

Substitute parts are identified when equivalent rectangular connector housings share identical electrical and mechanical specifications, including connector type, contact configuration, pitch, mounting method, and fastening mechanism. Alternative part numbers may differ in packaging format, color, insulation material composition, or compliance certifications while maintaining full functional compatibility.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334822321 are qualified based on strict equivalence across the following critical parameters:

• Connector Type: Plug housing configuration
• Contact Type: Male blade contact system
• Number of Positions: 20-position layout
• Pitch: 0.138" (3.50mm) contact spacing
• Number of Rows: 2-row arrangement
• Mounting Type: Free hanging in-line installation
• Contact Termination: Crimp connection method
• Fastening Type: Locking ramp mechanism
• Features: Sealed housing design

The substitute parts identified—Molex 0334822101 and Molex 0334822102—maintain identical electrical and mechanical specifications across all critical parameters. Variations between the main part and substitutes are limited to packaging format, color designation, insulation material composition, and compliance certifications. These variations do not affect functional compatibility or performance in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0334822321, 0334822101, and 0334822102—are active production components from Molex with identical electrical and mechanical specifications. Selection between these parts is determined by application-specific requirements:

0334822321 is the primary specification when black housing color is required and the original packaging format is specified.

0334822101 provides an equivalent alternative with black housing in bulk packaging format. This part carries ROHS3 compliance and REACH unaffected status, making it suitable for applications with environmental regulatory requirements.

0334822102 provides an equivalent alternative with gray housing in bulk packaging format. This part also carries ROHS3 compliance and REACH unaffected status. Selection of this part is appropriate when gray color coding is required for circuit board assembly or system integration purposes.

All three parts are suitable for direct substitution in applications requiring a 20-position, 3.50mm pitch rectangular connector plug housing with male blade contacts and locking ramp fastening.

Frequently Asked Questions (FAQ)

Q: Can 0334822101 and 0334822102 be used interchangeably with 0334822321?

A: Yes. All three parts share identical electrical and mechanical specifications including connector type, contact configuration, pitch, mounting method, and fastening mechanism. Differences in color and packaging do not affect functional compatibility.

Q: What is the primary difference between the substitute parts?

A: The main differences are color designation and packaging format. Part 0334822101 is black in bulk packaging, while 0334822102 is gray in bulk packaging. The original part 0334822321 is black with unspecified packaging.

Q: Are the substitute parts compliant with environmental regulations?

A: Parts 0334822101 and 0334822102 are both ROHS3 compliant and REACH unaffected. Compliance status for the original part 0334822321 is not specified in the provided data.

Q: Does insulation material composition affect substitution compatibility?

A: The original part 0334822321 uses Syndiotactic Polystyrene (SPS) glass-filled insulation. Substitute parts 0334822101 and 0334822102 use Polyamide (PA) nylon glass-filled insulation with Syndiotactic Polystyrene (SPS). Both material compositions are suitable for the MX150 33482 series and do not affect electrical or mechanical performance in equivalent applications.

Q: What is the operating temperature range for these parts?

A: Operating temperature range for substitute parts 0334822101 and 0334822102 is -40°C to 150°C. Operating temperature for the original part 0334822321 is not specified in the provided data.

Q: Are contacts included with these connector housings?

A: No. All three parts are housings only. Contacts must be sourced separately and crimped into the housing according to Molex specifications.

Q: What is the moisture sensitivity level for these parts?

A: The original part 0334822321 has moisture sensitivity level not applicable. Substitute parts 0334822101 and 0334822102 have MSL 1 (unlimited), indicating minimal moisture sensitivity and no special storage requirements.
