Primary Compatibility Criteria:

• Connector Type: RJ45 (mandatory)
• Mounting Type: Through Hole (mandatory)
• Orientation: 90° Angle Right (mandatory)
• Termination: Solder (mandatory)
• Shielding: Shielded with EMI Finger (mandatory)

Application Compatibility Criteria:

• Support for 10/100 Base-T networking
• AutoMDIX capability (where specified in applications)
• Power over Ethernet (PoE) support (where applicable)

Electrical & Physical Criteria:

• Contact Material: Gold finish (50.0µin minimum thickness)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 1-2250024-1 (TRP Connector B.V.)

The 1-2250024-1 is the direct functional equivalent to the obsolete 6605834-1. Both parts share identical specifications across all critical parameters: RJ45 connector type, 1 port, through-hole mounting, 90° right-angle orientation, solder termination, 0.555" height above board, Green-Yellow LED indicators, 6 cores per jack, shielded construction with EMI finger, phosphor bronze contacts with gold finish, and 0°C to 70°C operating temperature range. Both are ROHS3 compliant and REACH unaffected. The 1-2250024-1 maintains active product status with 8,268 units in stock, providing immediate availability for production continuity.

Secondary Substitutes: Bel Fuse Inc. SI-60000 Series (SI-60001-F, SI-60005-F, SI-60015-F, SI-60024-F, SI-60062-F, SI-60076-F, SI-60110-F, SI-60116-F, SI-60118-F)

All Bel Fuse SI-60000 series connectors maintain the mandatory core compatibility parameters: RJ45 connector type, 1 port, through-hole mounting, 90° right-angle orientation, solder termination, shielded construction with EMI finger, and gold-plated contacts at 50.0µin thickness. All are ROHS3 compliant and REACH unaffected with active product status.

Variations exist in the following non-critical parameters:

• Core Count: SI-60001-F, SI-60005-F, SI-60024-F, SI-60062-F, SI-60110-F, SI-60116-F, and SI-60118-F feature 4 cores; SI-60015-F and SI-60076-F feature 5 cores. The original 6605834-1 specifies 6 cores, but 4-core and 5-core variants remain electrically compatible for standard 10/100 Base-T applications.

• LED Color: Variants include Green-Green (SI-60001-F, SI-60015-F, SI-60076-F, SI-60118-F), Green-Yellow (SI-60005-F, SI-60110-F, SI-60116-F), Yellow-Green (SI-60062-F), and dual-color (SI-60024-F). LED color selection does not affect electrical performance.

• Mechanical Features: Tab direction varies (Up on 6605834-1 and 1-2250024-1; Down on all SI-60000 series). Board lock feature present on 6605834-1, 1-2250024-1, SI-60076-F, and SI-60118-F; board guide feature on remaining SI-60000 variants. These mechanical differences do not compromise electrical compatibility.

• Height Above Board: SI-60062-F specifies 0.545" (13.84mm), a 0.010" variance from the original 0.555" specification. This minor dimensional difference is acceptable for most PCB layouts.

• Operating Temperature: SI-60110-F and SI-60116-F match the original 0°C to 70°C range. SI-60118-F extends to -40°C to 85°C for extended temperature applications. Remaining SI-60000 variants do not specify operating temperature.

• Contact Material: SI-60000 series uses copper alloy contacts versus phosphor bronze in the original part. Both materials with gold finish provide equivalent electrical performance for 10/100 Base-T applications.

Selection Criteria:

For direct replacement requiring identical specifications, select 1-2250024-1. For applications where mechanical features (tab direction, board lock/guide) or LED color are not critical design constraints, SI-60000 series parts provide functional equivalence with superior inventory availability. SI-60110-F and SI-60116-F are recommended for temperature-matched applications within the 0°C to 70°C range. SI-60118-F is suitable for extended temperature environments requiring -40°C to 85°C operation.

Frequently Asked Questions (FAQ)

Q: Can I use SI-60000 series connectors as direct replacements for the 6605834-1?

A: Yes, with design considerations. All SI-60000 series parts maintain electrical compatibility for 10/100 Base-T networking. The primary differences are mechanical (tab direction, board lock vs. board guide), core count (4 or 5 versus 6), and LED color. These variations do not affect electrical performance. Verify that your PCB layout accommodates the tab direction change (Down on SI-60000 series versus Up on the original) and that the board lock/guide feature aligns with your mechanical requirements.

Q: What is the difference between 4-core, 5-core, and 6-core RJ45 connectors?

A: Core count refers to the number of internal contact positions within the jack. Standard 10/100 Base-T Ethernet uses 4 pairs (8 conductors total), which can be accommodated by 4-core, 5-core, or 6-core designs. The 6605834-1 specifies 6 cores, while most SI-60000 variants provide 4 cores. Both configurations support full 10/100 Base-T functionality. Core count does not limit electrical performance for standard networking applications.

Q: Why does the 1-2250024-1 have the same specifications as the 6605834-1 but different part numbers?

A: The 1-2250024-1 is the active production equivalent of the obsolete 6605834-1. Both are manufactured by TRP Connector B.V. and share identical electrical and mechanical specifications. The part number change reflects a product line update or packaging change (the 1-2250024-1 is packaged in Tray format). The 1-2250024-1 is the recommended direct replacement for new designs and production continuity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 6605834-1 and all listed substitute parts (1-2250024-1 and SI-60000 series) are ROHS3 compliant and REACH unaffected. All parts meet current environmental and regulatory requirements for commercial and industrial applications.

Q: What is the significance of the LED color variations?

A: LED color indicates the link and activity status indicators on the connector. The original 6605834-1 features Green-Yellow LEDs. Substitute parts offer Green-Green, Green-Yellow, Yellow-Green, or dual-color options. LED color is a visual indicator only and does not affect electrical performance or network functionality. Selection should be based on your system's visual status indication requirements.

Q: Can I use SI-60118-F in applications requiring the original 0°C to 70°C operating temperature range?

A: Yes. The SI-60118-F extends the operating temperature range to -40°C to 85°C, which encompasses the original 0°C to 70°C specification. This part is suitable for both standard and extended temperature applications. If your design operates strictly within 0°C to 70°C, SI-60110-F or SI-60116-F provide temperature-matched alternatives.

Q: What is the impact of the 0.010" height difference between the 6605834-1 (0.555") and SI-60062-F (0.545")?

A: The 0.010" (0.254mm) height variance is minimal and acceptable for most PCB layouts. This difference represents less than 2% variation from the original specification. Verify that your PCB clearance and component placement accommodate this minor dimensional change. For applications with strict height constraints, select parts with matching or greater height specifications.

Q: Are AutoMDIX and PoE support maintained across all substitute parts?

A: AutoMDIX support is specified for 1-2250024-1, SI-60001-F, SI-60005-F, SI-60024-F, SI-60062-F, SI-60110-F, SI-60116-F, and SI-60118-F. SI-60015-F and SI-60076-F do not specify AutoMDIX in their applications. PoE support is specified only for the 6605834-1 and 1-2250024-1. For applications requiring both AutoMDIX and PoE functionality, use 1-2250024-1. For AutoMDIX-only applications, SI-60000 series variants with AutoMDIX designation are suitable. For standard 10/100 Base-T without AutoMDIX or PoE, all parts are compatible.
