SI-60173-F Equivalent & Substitute Parts

Part Overview

The SI-60173-F is a 1 Port RJ45 Through Hole modular connector manufactured by Stewart Connector, part of the MagJack® ST SI-60000 series. This shielded connector features a 90° right angle orientation with solder termination and board lock functionality. The product is Active status and ROHS3 compliant, making it suitable for PCB-mounted Ethernet applications requiring EMI shielding and mechanical stability.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative configurations that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-60173-F is determined by the following critical parameters:

• Connector Type & Port Configuration: RJ45 jack with single port through-hole mounting
• Mechanical Orientation: 90° right angle orientation with downward tab direction
• Termination Method: Solder termination for PCB integration
• Electrical Shielding: EMI shielding capability for noise rejection
• Contact Properties: Copper alloy with gold finish for reliable signal transmission
• Compliance & Environmental: ROHS3 compliance and MSL 1 rating for moisture sensitivity

The substitute part 68899-001LF shares the core mechanical and electrical interface characteristics (RJ45 jack, 1 port, through-hole, 90° right angle, solder termination, copper alloy contacts with gold finish). However, this substitute operates as an unshielded Cat3 connector, representing a functional alternative where EMI shielding requirements may be relaxed or where the application permits reduced electromagnetic interference protection.

Parameter Comparison

Engineering Selection Recommendations

SI-60173-F remains the primary selection for applications requiring shielded RJ45 connectivity with EMI protection. The ROHS3 compliance and MagJack® series designation provide established reliability for industrial and commercial Ethernet implementations.

68899-001LF serves as a functional substitute where shielding is not a design requirement or where unshielded Cat3 performance is acceptable. This part maintains mechanical and electrical interface compatibility through identical mounting, orientation, termination, and contact properties. The RoHS compliance (standard) and MSL 1 rating ensure equivalent environmental handling characteristics. The polyamide housing and GXT™ contact finish represent alternative material specifications that do not compromise core connector functionality for unshielded applications.

Selection between these parts should be based on electromagnetic interference requirements and application-specific shielding specifications rather than general performance considerations.

Frequently Asked Questions (FAQ)

Q: Can 68899-001LF replace SI-60173-F in all applications?

A: No. The 68899-001LF is unshielded, while the SI-60173-F includes EMI shielding. Substitution is valid only for applications where electromagnetic interference protection is not required or where the design permits unshielded operation.

Q: Are the physical dimensions and PCB footprints identical?

A: Both connectors share 90° right angle orientation, through-hole mounting, and downward tab direction. However, the SI-60173-F includes an EMI finger shield that may affect board layout. Physical verification against design specifications is necessary before substitution.

Q: What is the difference between ROHS3 and RoHS compliance?

A: SI-60173-F carries ROHS3 certification, while 68899-001LF carries standard RoHS compliance. Both meet hazardous substance restrictions; ROHS3 represents a more recent compliance designation. Both are acceptable for regulated markets.

Q: Do both connectors support the same data rates?

A: The 68899-001LF is rated for Cat3 performance. The SI-60173-F category rating is not specified in the provided data. Consult detailed electrical specifications and application requirements to confirm data rate compatibility.

Q: What is the difference in contact finish thickness?

A: SI-60173-F specifies 50.0µin (1.27µm) gold finish thickness, while 68899-001LF specifies 30.0µin (0.76µm). Both thicknesses provide adequate contact durability; the SI-60173-F offers increased wear resistance for high-cycle mating applications.

Q: Are both parts available in the same packaging?

A: SI-60173-F packaging is not specified. 68899-001LF is supplied in Tube packaging. Confirm packaging requirements and handling procedures with your procurement specifications.
