Substitute Part Grouping Explanation

Substitute parts for the 1840718-1 are identified based on strict equivalence across the following critical parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Applications: 10/100/1000 Base-T with AutoMDIX support
• Mounting Type: Through Hole PCB mounting
• Termination Method: Solder
• Series Classification: MagJack® integrated magnetics
• Electrical Performance: 8-core jack configuration for full Ethernet compliance

The substitute part L830-1J1C-43 meets all these criteria and is therefore classified as an equivalent alternative for the 1840718-1 in applications requiring single-port RJ45 Ethernet connectivity with integrated magnetics and AutoMDIX functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the 1840718-1 and L830-1J1C-43 are active production parts from TRP Connector B.V. within the MagJack® series. The L830-1J1C-43 carries ROHS3 compliance and REACH unaffected status, confirming regulatory alignment for current manufacturing standards. Selection between these parts should be based on:

1. Orientation requirements: The L830-1J1C-43 specifies 90° angle (right) orientation, which may be a design constraint for PCB layout.
2. Inventory availability: The 1840718-1 has higher stock levels (1,159 units) compared to L830-1J1C-43 (669 units).
3. Regulatory compliance documentation: The L830-1J1C-43 provides explicit RoHS3 and REACH certification data.

Both parts are suitable for 10/100/1000 Base-T Ethernet applications with AutoMDIX functionality and through-hole PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can L830-1J1C-43 be used as a direct replacement for 1840718-1?

A: Yes, within the constraints of PCB layout. Both parts are single-port RJ45 MagJack® connectors with identical electrical specifications (10/100/1000 Base-T, AutoMDIX, 8-core configuration, solder termination, through-hole mounting). The primary design consideration is the 90° angle (right) orientation of the L830-1J1C-43, which must be compatible with your PCB footprint.

Q: What are the critical parameters for RJ45 connector substitution?

A: For modular RJ45 connectors in this category, the critical parameters are: connector type (RJ45), number of ports (1), application support (10/100/1000 Base-T with AutoMDIX), mounting type (through-hole), termination method (solder), and core count (8). Deviations in any of these parameters indicate incompatibility.

Q: Are there compliance differences between these parts?

A: The L830-1J1C-43 explicitly documents ROHS3 compliance and REACH unaffected status. The 1840718-1 compliance status is not specified in available data. For applications requiring documented regulatory compliance, the L830-1J1C-43 provides explicit certification.

Q: What is the significance of the MagJack® designation?

A: MagJack® indicates integrated magnetics within the connector assembly, providing the transformer and filtering functions required for Ethernet signal conditioning. Both parts carry this designation, confirming equivalent magnetic integration.

Q: How does orientation affect part selection?

A: The L830-1J1C-43 is specified as 90° angle (right) orientation, meaning the connector body is angled relative to the PCB plane. The 1840718-1 orientation is not specified. PCB layout and available space must accommodate the selected orientation. Orientation mismatch will result in physical incompatibility.
