Key Parameters

Substitute Part Grouping Explanation

The Molex 0442820001 qualifies as a direct substitute for the 0442820005 based on the following critical parameters:

• Connector Type & Configuration: Both are jack connectors with identical 8p8c (RJ45, Ethernet) contact arrangement
• Mechanical Orientation: Both feature 90° right-angle mounting with identical surface mount configuration
• Electrical Protection: Both incorporate shielding with EMI finger protection and Cat3 rating
• Termination Method: Both use solder termination
• Operating Environment: Both support the same -40°C to 70°C temperature range
• Series Compatibility: Both belong to the Molex 44282 series
• Compliance: Both are ROHS3 compliant with EAR99 ECCN classification

The primary difference between these parts is contact finish thickness and product status, neither of which affects functional interchangeability in the application.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0442820001 is the appropriate substitute for the obsolete 0442820005. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector configuration, orientation, shielding, and operating temperature range. The 0442820001 is currently in active production status with 1876 units available in inventory, ensuring supply chain continuity.

The contact finish thickness difference (50.0µin versus 30.0µin) represents an enhancement in the substitute part, providing increased durability without affecting functional compatibility. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, supporting equivalent environmental performance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0442820001 be used as a direct replacement for the 0442820005?

A: Yes. Both parts are identical in connector type, contact configuration, orientation, mounting method, shielding, and operating specifications. The 0442820001 is the active production equivalent.

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

A: The 0442820001 features a thicker gold contact finish (50.0µin versus 30.0µin). This represents improved contact durability and wear resistance without altering electrical or mechanical compatibility.

Q: Are there packaging differences between these parts?

A: The 0442820005 packaging specification was not provided. The 0442820001 is available in Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging options.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 0442820005 and 0442820001 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and EAR99 ECCN classification.

Q: What is the Cat3 rating and does it apply to both parts?

A: Cat3 (Category 3) is an Ethernet cable and connector rating supporting data transmission up to 10 Mbps. Both parts carry this identical rating.

Q: Are there any temperature or environmental limitations?

A: Both parts operate across the identical temperature range of -40°C to 70°C with MSL 1 rating, indicating no moisture sensitivity restrictions during storage or handling.
