Molex 0442820002 Modular Connector RJ45 Jack – Equivalent & Substitute Parts

Part Overview

The Molex 0442820002 is a modular jack connector designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and shielded construction featuring EMI finger protection. This connector is rated for Cat3 performance and is designed for surface mount solder termination on printed circuit boards with board guide and solder retention features.

The 0442820002 carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this connector type.

Substitute Part Grouping Explanation

The Molex 0442820002 has one direct substitute within the same product series: the Molex 0442820001. Substitution eligibility is determined by the following critical parameters that must remain identical:

• Connector type (Jack)
• Contact configuration (8p8c RJ45 Ethernet)
• Orientation (90° right-angle)
• Mounting method (Surface Mount)
• Termination type (Solder)
• Shielding design (Shielded with EMI finger)
• Performance category (Cat3)
• Housing material (Polyamide, Nylon, Glass Filled)
• Operating temperature range (-40°C ~ 70°C)
• Regulatory compliance (ROHS3)

Both parts belong to the Molex 44282 series and share identical mechanical and electrical specifications within these core parameters. Differences in packaging format and contact finish thickness do not affect functional interchangeability in the application.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0442820001 is the direct functional equivalent to the 0442820002 for all electrical and mechanical applications. The 0442820001 is the preferred selection for new designs and ongoing production due to its Active product status, compared to the Obsolete status of the 0442820002.

The contact finish thickness difference (30.0µin versus 50.0µin) does not affect functional interchangeability. Both parts maintain identical electrical performance, mechanical fit, and environmental ratings. The 0442820001 offers superior supply chain availability with 1876 units in stock versus 691 units for the obsolete variant.

Both parts maintain full ROHS3 compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040), ensuring compliance continuity across substitution.

Frequently Asked Questions (FAQ)

Q: Can the 0442820001 be used as a direct replacement for the 0442820002 in existing designs?

A: Yes. Both connectors share identical electrical specifications, mechanical dimensions, mounting footprint, and performance ratings. The 0442820001 is functionally equivalent and can be substituted without design modification.

Q: What is the significance of the contact finish thickness difference?

A: The contact finish thickness (30.0µin for 0442820002 versus 50.0µin for 0442820001) does not affect electrical performance or mechanical compatibility. Both thicknesses provide adequate gold plating for reliable contact performance in Cat3 Ethernet applications.

Q: Why is the 0442820002 marked as Obsolete?

A: The Obsolete status indicates that Molex has discontinued active production and support for this part number. The 0442820001 represents the current active equivalent within the same product series.

Q: Are there packaging differences between these parts?

A: Yes. The 0442820002 packaging is not specified in available documentation. The 0442820001 is available in Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) formats. Packaging selection should be based on assembly process requirements and volume needs.

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

A: Yes. Both the 0442820002 and 0442820001 are ROHS3 compliant, carry MSL Level 1 (Unlimited), and share identical ECCN and HTSUS classifications. Environmental operating range is identical at -40°C to 70°C.

Q: Which part should be selected for new production?

A: The Molex 0442820001 should be selected for new designs and ongoing production due to its Active status and superior inventory availability. The 0442820002 should only be used when existing stock must be consumed or when supporting legacy systems already deployed with this part number.
