Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1840433-1 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Applications: 10/100/1000 Base-T, AutoMDIX
• Number of Cores per Jack: 8
• Shielding: Shielded, EMI Finger
• Contact Finish: Gold
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Secondary Tolerance Parameters:

• Height Above Board: ±0.02" (±0.51mm) variance acceptable
• Operating Temperature: Minimum -40°C to 0°C; Maximum 70°C to 85°C
• Contact Finish Thickness: 6.0µin to 50.0µin (0.152µm to 1.27µm)
• Housing Material: Polyester, PET, LCP, or PBT variants
• Shield Material: Brass or Copper Alloy
• Contact Material: Phosphor Bronze or Copper Alloy

The following parts meet these criteria and are qualified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Full Specification Match (Recommended for Direct Replacement):

2301994-6 (TE Connectivity AMP Connectors) and JXKM-0004NL (Pulse Electronics) provide the closest alignment to the 1840433-1 specification. Both maintain the -40°C to 85°C operating temperature range of the original part, ensuring compatibility in extended temperature environments. Both are ROHS3 compliant and carry active product status with established supply chains.

Tier 2 - Compatible with Temperature Derating:

A60-113-300P492 (Mercury United Electronics), ARJ11E-MASA-M2 (Abracon LLC), and L835-1X1T-S7 (Bel Fuse Inc.) are functionally compatible but operate within a 0°C to 70°C temperature range. These parts are suitable for applications not requiring the full -40°C to 85°C envelope. All three maintain ROHS3 compliance and active product status.

Tier 3 - Limited Data Availability:

2250049-1 (TRP Connector B.V.) lacks detailed specification data in available documentation. While it shares the same manufacturer as the original part and maintains ROHS3 compliance, insufficient parameter information prevents full compatibility assessment.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring regulatory and environmental compatibility. REACH status is either unaffected or vendor-undefined across all alternatives, presenting no regulatory barriers to substitution.

Frequently Asked Questions (FAQ)

Q: Can I use A60-113-300P492 as a direct replacement for 1840433-1 in all applications?

A: A60-113-300P492 is mechanically and electrically compatible for 10/100/1000 Base-T Ethernet applications. However, its operating temperature range is limited to 0°C to 70°C, compared to the original part's -40°C to 85°C range. Use this substitute only in applications where the temperature envelope does not exceed these limits.

Q: What is the significance of the height difference between L835-1X1T-S7 (0.448") and the original 1840433-1 (0.555")?

A: The L835-1X1T-S7 has a lower profile by approximately 0.107 inches (2.72mm). This dimensional difference may affect PCB layout and component clearance. Verify board-level spacing and connector accessibility before substitution.

Q: Does JXKM-0004NL include integrated LEDs, and does this affect compatibility?

A: JXKM-0004NL includes green-yellow LED indicators, whereas the original 1840433-1 does not. If your PCB design does not accommodate LED connections, this part requires design modification. Alternatively, select LED-free alternatives such as 2301994-6 or A60-113-300P492.

Q: Are all substitute parts available in the same packaging as the original?

A: Packaging varies across substitutes. The original 1840433-1 packaging is not specified. Substitute parts are available in Bulk (2250049-1), Cut Tape (2301994-6), and Tray formats (A60-113-300P492, ARJ11E-MASA-M2, JXKM-0004NL, L835-1X1T-S7). Confirm packaging requirements with your procurement process.

Q: What is the difference between 10/100/1000 Base-T and 10/100/1000 Base-TX?

A: Both designations refer to Gigabit Ethernet compatibility. Base-T and Base-TX are functionally equivalent for RJ45 connector applications. ARJ11E-MASA-M2 is specified as Base-TX and is fully compatible with Base-T systems.

Q: Which substitute offers the best long-term availability?

A: 2301994-6 (TE Connectivity AMP Connectors) and JXKM-0004NL (Pulse Electronics) are from established manufacturers with active product status and documented supply chains. Both are recommended for designs requiring extended production lifecycles.
