Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6605857-1 are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

Primary Substitution Criteria:

• Connector Type: RJ45
• Number of Ports: 1
• Applications: 10/100 Base-T, AutoMDIX
• Mounting Type: Through Hole
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Number of Cores per Jack: 4
• Contact Finish: Gold
• Contact Finish Thickness: 50.0µin (1.27µm)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in secondary parameters such as LED color, tab direction, height above board, and operating temperature range are noted but do not preclude substitution when the primary criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component integration. The 6605857-1 and its substitutes are functionally equivalent for 10/100 Base-T network applications with AutoMDIX support.

Availability Considerations:

• SI-60001-F offers the highest inventory level (21,818 units), providing supply chain flexibility
• SI-60118-F provides the second-highest availability (12,455 units) with extended operating temperature range (-40°C to 85°C)
• SI-60182-F matches the extended temperature specification of the original part while maintaining full electrical equivalence

Manufacturer Alternatives:

• TRP Connector B.V. 5-6605761-1 maintains original manufacturer continuity with 3,481 units available
• Bel Fuse Inc. MagJack® ST SI-60000 series parts provide cross-manufacturer substitution with consistent performance specifications

Frequently Asked Questions (FAQ)

Q: Can SI-60001-F directly replace 6605857-1 in existing PCB designs? A: Yes. Both parts share identical core specifications: RJ45 connector type, 1 port, 10/100 Base-T with AutoMDIX, through-hole solder termination, shielded construction with EMI finger, 4 cores per jack, and gold contact finish at 50.0µin thickness. PCB footprint compatibility is maintained.

Q: What is the difference between parts with different LED color configurations? A: LED color variations (Green-Yellow, Green-Green, Yellow-Green) are cosmetic indicators only and do not affect electrical performance or network functionality. Selection should be based on visual indication requirements in the end application.

Q: Are there operating temperature differences between substitute parts? A: Yes. The original 6605857-1 operates from -40°C to 85°C. SI-60110-F operates from 0°C to 70°C, while other Bel Fuse parts do not specify operating temperature limits. For applications requiring extended temperature range, SI-60118-F and SI-60182-F both support -40°C to 85°C operation.

Q: What does "Board Lock" versus "Board Guide" mean in the feature specifications? A: Both features provide mechanical retention on the PCB. Board Lock provides positive locking engagement, while Board Guide provides alignment without locking. Both are mechanically compatible with standard RJ45 jack designs and do not affect electrical substitution.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, meeting current environmental and regulatory standards for component procurement.

Q: What is the significance of tab direction (Up versus Down)? A: Tab direction refers to the orientation of the retention tab on the connector housing. This is a mechanical design feature that affects PCB layout and assembly orientation but does not impact electrical performance or functional substitution.
