TRP Connector 1840140-3 Equivalent & Substitute Parts

Part Overview

The TRP Connector 1840140-3 is a 2-port RJ45 modular connector designed for through-hole PCB mounting with support for 10/100/1000 Base-T Ethernet and Power over Ethernet (PoE) applications. This MagJack® series connector provides dual-port functionality in a single package, enabling compact network interface designs. The part is currently in active inventory status with 767 pieces available as new original stock.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design revisions necessitate component alternatives that maintain functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 1840689-3 is classified as functionally equivalent based on the following critical parameters that determine substitutability:

• Connector Type & Port Configuration: Both parts feature RJ45 connectors with 2-port configuration, maintaining identical electrical interface specifications
• Mounting Technology: Both utilize through-hole solder termination, ensuring compatibility with existing PCB designs
• Ethernet Standards Support: Both support 10/100/1000 Base-T operation, providing equivalent data rate capabilities
• Series Classification: Both belong to the MagJack® product line, confirming design family compatibility
• Packaging Difference: The substitute part 1840689-3 is supplied in bulk packaging, whereas the main part uses standard packaging

The primary distinction between these parts is the packaging format and the inclusion of AutoMDIX functionality in the substitute part, which does not affect mechanical or primary electrical compatibility for standard through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1840140-3 and 1840689-3 are active products from TRP Connector B.V. within the MagJack® series. The substitute part 1840689-3 carries ROHS3 compliance and REACH unaffected status, confirming regulatory alignment for applications requiring environmental compliance documentation.

Selection between these parts should be based on:

• Packaging Requirements: Choose 1840689-3 when bulk packaging is required for high-volume manufacturing processes
• Inventory Availability: Both parts maintain adequate stock levels; selection may depend on procurement lead times and supply chain requirements
• Regulatory Documentation: The substitute part provides explicit ROHS3 and REACH compliance statements suitable for regulated industries

The mechanical and electrical compatibility between these parts supports direct substitution in through-hole PCB designs without requiring layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 1840689-3 be used as a direct replacement for 1840140-3 in existing PCB designs?

A: Yes. Both parts share identical connector type (RJ45), port configuration (2-port), mounting method (through-hole solder), and Ethernet standard support (10/100/1000 Base-T). The primary difference is packaging format and the addition of AutoMDIX functionality in the substitute part, which does not affect mechanical fit or primary electrical operation.

Q: What is the significance of the packaging difference between these parts?

A: The main part uses standard packaging while the substitute part 1840689-3 is supplied in bulk packaging. This distinction affects procurement processes and inventory management but does not impact component performance or compatibility.

Q: Are there orientation differences between these connectors?

A: The substitute part 1840689-3 specifies 90° angle (right) orientation. The main part does not provide orientation specification in the available data. Verify PCB layout requirements before selection to ensure mechanical compatibility with your design.

Q: What compliance certifications apply to the substitute part?

A: Part 1840689-3 is ROHS3 compliant and REACH unaffected. These certifications confirm compliance with European environmental and chemical safety regulations. Verify that your application requirements align with these compliance standards.

Q: Does AutoMDIX functionality in the substitute part affect compatibility?

A: AutoMDIX is an additional feature in part 1840689-3 that automatically detects and adjusts to straight-through or crossover cable configurations. This feature does not interfere with standard Ethernet operation and provides enhanced flexibility for network installations.

Q: What is the moisture sensitivity level (MSL) rating?

A: The substitute part 1840689-3 carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.
