Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0441930008 is determined by strict alignment of the following critical parameters:

• Connector Type: Jack Modular Connector
• Configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Surface Mount
• Termination Method: Solder
• Shielding: Unshielded
• Number of Ports: 2
• Number of Rows: 1
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Polyamide (PA), Nylon, Glass Filled
• Operating Temperature Range: -40°C ~ 70°C

The Molex 0441930003 meets all these core mechanical and electrical requirements. Variations in performance rating (Cat3 vs. Cat4) and contact finish thickness do not preclude substitution when system bandwidth requirements are compatible with the lower Cat3 specification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0441930003 is the direct substitute for the obsolete Molex 0441930008. Both components share identical mechanical form factors, mounting characteristics, and core electrical properties within the 8p8c modular connector family.

The primary distinction is the performance rating: the 0441930003 is rated for Cat3 applications, while the 0441930008 is rated for Cat4. This difference is relevant only when the system design requires Cat4 bandwidth specifications. For applications operating within Cat3 bandwidth parameters, the 0441930003 provides full functional equivalence.

The 0441930003 offers the additional advantage of active product status with established supply chain availability (2342 pcs in stock), compared to the obsolete status of the main part. Both components maintain ROHS3 compliance and identical environmental ratings (-40°C ~ 70°C operating temperature).

The increased contact finish thickness on the 0441930003 (50.0µin vs. 30.0µin) provides enhanced durability and contact reliability over extended operational cycles.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0441930003 be used as a direct replacement for the Molex 0441930008?

A: Yes, the 0441930003 is a direct mechanical and electrical substitute provided the system design does not require Cat4 bandwidth specifications. Both connectors share identical form factors, mounting methods, termination approaches, and environmental ratings.

Q: What is the significance of the Cat3 vs. Cat4 rating difference?

A: Cat3 and Cat4 are performance classifications for Ethernet connectivity. Cat4 supports higher bandwidth than Cat3. If your application operates within Cat3 specifications, the 0441930003 is fully suitable. If Cat4 performance is mandatory, alternative components rated for Cat4 must be evaluated.

Q: Are there packaging differences between these parts?

A: The 0441930008 packaging information is not specified in available data. The 0441930003 is supplied in Tape & Reel (TR) format, which is standard for surface mount production environments.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both the 0441930008 and 0441930003 are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Why is the contact finish thickness different?

A: The 0441930003 features a thicker gold contact finish (50.0µin vs. 30.0µin). This increased thickness enhances contact durability and extends the operational lifespan under repeated mating cycles, providing improved reliability for high-cycle applications.

Q: Is the 0441930003 currently available?

A: Yes. The 0441930003 maintains active product status with 2342 pieces in current inventory, ensuring reliable supply chain access compared to the obsolete 0441930008.
