Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1840419-3 is determined by strict alignment with the following core parameters: Connector Type (RJ45), Number of Ports (1), Applications (10/100 Base-T with AutoMDIX), Mounting Type (Through Hole), Orientation (Vertical), Termination (Solder), Shielding (Shielded), and Number of Cores per Jack (4). The substitute part 74990101210 from Würth Elektronik meets all these critical functional and mechanical requirements, making it electrically and mechanically compatible for direct substitution in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1840419-3 and 74990101210 are Active products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The 74990101210 offers an extended operating temperature range (-40°C to 85°C) compared to the 1840419-3 (0°C to 70°C), making it suitable for applications requiring broader thermal performance. The height above board differs by 0.039" (0.99mm), which may be a consideration in space-constrained PCB layouts. Both connectors maintain identical electrical functionality for 10/100 Base-T AutoMDIX applications and are suitable for direct substitution where thermal and spatial requirements align.

Frequently Asked Questions (FAQ)

Q: Can the 74990101210 directly replace the 1840419-3 in existing designs? A: Yes, the 74990101210 is electrically and mechanically compatible for direct substitution. Both connectors share identical RJ45 configuration, 1 port, 10/100 Base-T AutoMDIX functionality, vertical through-hole mounting, and solder termination. PCB layout verification is recommended to confirm the 0.039" height difference does not impact your specific application.

Q: What are the key differences between these two connectors? A: The primary differences are operating temperature range (1840419-3: 0°C to 70°C; 74990101210: -40°C to 85°C), contact material (Phosphor Bronze vs. Tin), contact finish thickness (50.0µin vs. 30.0µin), shield material (Brass vs. Copper Alloy), height above board (16.51mm vs. 17.50mm), and packaging format (Tray vs. Tube).

Q: Are both parts RoHS and REACH compliant? A: Yes, both the 1840419-3 and 74990101210 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Does packaging format affect compatibility? A: Packaging format (Tray vs. Tube) does not affect electrical or mechanical compatibility. The choice between packaging options depends on your procurement, storage, and assembly process requirements.

Q: Which connector should I select for extended temperature applications? A: The 74990101210 is suitable for applications requiring operation beyond 0°C to 70°C, as it supports -40°C to 85°C. The 1840419-3 is appropriate for standard temperature range applications.
