Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1-6605752-1 are qualified based on the following criteria:

Core Compatibility Parameters:

• Connector Type: RJ45 (mandatory match)
• Number of Ports: 1 (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Orientation: 90° Angle (Right) (mandatory match)
• Termination: Solder (mandatory match)
• Number of Cores per Jack: 4 (mandatory match)
• Shielding: Shielded, EMI Finger (mandatory match)
• Contact Finish: Gold (mandatory match)
• Contact Finish Thickness: 50.0µin (1.27µm) (mandatory match)

Variable Parameters Allowing Substitution:

• Applications: Original supports 10 Base-T; substitutes support 10/100 Base-T (backward compatible)
• LED Color: Original is Green-Green; substitutes vary (Green-Yellow, Yellow-Green, Green-Yellow, Green-Green)
• Tab Direction: Original is Up; substitutes are Down (mechanical variation)
• Features: Original has Board Lock; some substitutes have Board Guide or Board Lock
• Operating Temperature: Original is 0°C ~ 70°C; some substitutes extend to -40°C ~ 85°C
• Height Above Board: Original is 0.555" (14.10mm); some substitutes vary or are unspecified
• Housing Material: Original is PET/Polyester; substitutes are Thermoplastic
• Contact Material: Original is Phosphor Bronze; substitutes are Copper Alloy
• Shield Material: Original is Brass; substitutes are Copper Alloy

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN/HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original 1-6605752-1.

For direct mechanical and electrical replacement with identical operating temperature range (0°C ~ 70°C): SI-60110-F is the closest functional equivalent, maintaining the same operating temperature specification and offering 10/100 Base-T backward compatibility.

For applications requiring extended operating temperature range (-40°C ~ 85°C): SI-60118-F and SI-60182-F both extend the operating temperature specification while maintaining Board Lock features. SI-60118-F provides Green-Green LED configuration matching the original; SI-60182-F provides Yellow-Green configuration with 0.545" (13.84mm) height specification.

For applications with Board Guide feature preference: SI-60001-F, SI-60005-F, and SI-60024-F provide Board Guide alternatives with 10/100 Base-T support. SI-60001-F and SI-60118-F maintain Green-Green LED configuration.

For height-critical PCB layouts: SI-60062-F and SI-60182-F both specify 0.545" (13.84mm) height, compared to the original 0.555" (14.10mm), providing a 0.010" (0.26mm) reduction in board clearance requirement.

All substitute parts maintain identical contact finish thickness (50.0µin / 1.27µm), shielding configuration (Shielded, EMI Finger), and core count (4 cores), ensuring electrical performance compatibility within the RJ45 standard.

Frequently Asked Questions (FAQ)

Q: Can SI-60001-F, SI-60005-F, or SI-60024-F be used as direct replacements for 1-6605752-1?

A: These parts are mechanically and electrically compatible as substitutes. All maintain RJ45 connector type, 1-port configuration, through-hole mounting, 90° right-angle orientation, solder termination, 4-core jack, shielded EMI finger design, and gold contact finish at 50.0µin thickness. The primary differences are tab direction (Down vs. Up), features (Board Guide vs. Board Lock), and LED color variations. The 10/100 Base-T capability is backward compatible with 10 Base-T applications.

Q: What is the difference between Board Lock and Board Guide features?

A: Board Lock provides mechanical retention through a locking mechanism that secures the connector to the PCB. Board Guide provides alignment guidance without locking retention. The choice depends on application requirements for connector retention and serviceability.

Q: Why do some substitute parts have unspecified operating temperature ranges?

A: Operating temperature specifications are provided only when explicitly documented by the manufacturer. Parts with unspecified ranges should be evaluated against application thermal requirements before selection.

Q: Are there mechanical compatibility concerns with tab direction differences (Up vs. Down)?

A: Tab direction affects connector orientation and cable entry angle. Substitutes with Down tab direction require PCB layout verification to ensure cable routing compatibility with the original Up tab design.

Q: Which substitute part offers the best thermal performance for extended temperature applications?

A: SI-60118-F and SI-60182-F both support -40°C ~ 85°C operating range, compared to the original 0°C ~ 70°C specification. Both maintain Board Lock features and ROHS3 compliance. SI-60118-F provides Green-Green LED matching the original; SI-60182-F provides Yellow-Green LED with reduced height specification (0.545" vs. 0.555").

Q: Are all substitute parts ROHS3 compliant and REACH unaffected?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original 1-6605752-1. All share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the inventory availability for substitute parts?

A: Current inventory levels vary: SI-60001-F (21,818 pcs), SI-60005-F (12,380 pcs), SI-60024-F (3,069 pcs), SI-60062-F (8,833 pcs), SI-60110-F (1,002 pcs), SI-60118-F (12,455 pcs), SI-60182-F (3,842 pcs). Availability should be confirmed at time of procurement.
