Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1840466-1 is determined by strict alignment of the following critical parameters:

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

The substitute part 1840440-1 meets all these core electrical and mechanical requirements. Variations in height above board, operating temperature range, and packaging format do not affect functional compatibility in applications where the 1840466-1 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The 1840440-1 is the direct substitute for the obsolete 1840466-1. Both connectors are manufactured by TRP Connector B.V. and share identical electrical specifications for 10/100/1000 Base-T Ethernet applications. The substitute part is currently in active production status with higher inventory availability.

Key considerations for selection:

• The 1840440-1 operates across an extended temperature range (-40°C to 85°C) compared to the original part (0°C to 70°C), providing broader environmental compatibility.
• Height above board differs by 0.35mm (14.10mm versus 13.75mm), which may require PCB layout verification for applications with tight vertical clearance constraints.
• Both parts maintain identical ROHS3 compliance and contact specifications.
• The substitute part includes panel stops as an additional feature not present in the original design.

Frequently Asked Questions (FAQ)

Q: Can the 1840440-1 directly replace the 1840466-1 in existing designs?

A: Yes. Both connectors share identical electrical specifications, pinout, solder termination, and mechanical mounting type. The 0.35mm height difference requires verification only if PCB layout includes tight vertical constraints.

Q: What is the significance of the extended operating temperature range in the substitute part?

A: The 1840440-1 operates from -40°C to 85°C, compared to 0°C to 70°C for the original part. This provides additional environmental margin for applications requiring operation in extreme temperature conditions. If your application operates within 0°C to 70°C, both parts are functionally equivalent.

Q: Are there packaging differences between these parts?

A: The 1840466-1 was supplied in standard packaging, while the 1840440-1 is available in bulk packaging. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: Why is the original part listed as obsolete?

A: The 1840466-1 has been discontinued by the manufacturer. The 1840440-1 is the active production equivalent and is the recommended selection for new designs and ongoing procurement.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1840466-1 and 1840440-1 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes.
