SI-50076-F Equivalent & Substitute Parts

Part Overview

The SI-50076-F is a 1 Port RJ45 Through Hole modular connector manufactured by Stewart Connector, designed for 10/100/1000 Base-T Ethernet applications with AutoMDIX capability. This connector features a 90° right-angle orientation, solder termination, and shielded design with EMI finger protection. The part is currently Active in product status with 881 pieces in stock inventory. Equivalent and substitute parts are identified to support procurement flexibility, supply chain continuity, and design alternatives when the primary part becomes unavailable or when specific application requirements necessitate alternative connector specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-50076-F is determined by strict alignment with the following critical parameters: RJ45 connector type, single port configuration, through-hole mounting, 90° right-angle orientation, solder termination, 10/100/1000 Base-T and AutoMDIX application support, shielded construction with EMI finger, 12 cores per jack, gold contact finish, and RoHS3 compliance. All identified substitute parts meet these core electrical and mechanical requirements, ensuring functional interchangeability within the specified application domain. Variations in secondary parameters such as height above board, contact finish thickness, shield material composition, and housing material do not preclude substitution when primary functional criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All four connectors—SI-50076-F, 0816-1X1T-23-F, 7499111000A, and JK0-0187NL—maintain Active product status and satisfy RoHS compliance requirements, confirming their suitability for current design implementations. The SI-50076-F and 0816-1X1T-23-F demonstrate identical height above board specifications (0.536" / 13.61mm) and contact finish thickness (50.0µin / 1.27µm), offering the closest mechanical and electrical alignment. The JK0-0187NL variant includes integrated LED indicators (Green - Green), which may provide functional advantages in applications requiring visual status feedback, though this feature represents a design differentiation rather than a substitution requirement. The 7499111000A exhibits a marginally increased height above board (0.570" / 14.50mm) and reduced contact finish thickness (30.0µin / 0.76µm), warranting PCB layout verification prior to implementation. All parts are manufactured by established connector suppliers with documented compliance certifications and active inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the JK0-0187NL be used as a direct substitute for the SI-50076-F?

A: Yes. The JK0-0187NL meets all core substitution criteria: RJ45 connector type, single port, through-hole mounting, 90° right-angle orientation, solder termination, 10/100/1000 Base-T and AutoMDIX support, shielded EMI finger design, 12 cores per jack, and gold contact finish. The integrated green LED indicators represent an additional feature rather than a compatibility barrier.

Q: What is the significance of the height above board variation between parts?

A: Height above board differences (ranging from 0.536" to 0.570") may impact PCB layout clearance and component spacing. The SI-50076-F and 0816-1X1T-23-F share identical height specifications. The 7499111000A's increased height (0.570") requires verification against PCB design constraints before selection.

Q: Does contact finish thickness affect electrical performance?

A: Contact finish thickness variations (30.0µin to 50.0µin) do not alter electrical performance within the specified 10/100/1000 Base-T application range. All parts maintain gold contact finish for corrosion resistance and signal integrity. Thickness differences reflect manufacturing process variations among suppliers.

Q: Are there packaging differences that affect procurement?

A: Yes. The SI-50076-F is supplied without specified packaging, 0816-1X1T-23-F in Tray, 7499111000A in Tube, and JK0-0187NL in Tray. Packaging selection may influence handling, storage, and bulk order considerations but does not affect connector functionality.

Q: Which substitute part offers the closest specification match to the SI-50076-F?

A: The 0816-1X1T-23-F (Bel Fuse Inc.) provides the closest specification alignment, matching height above board (0.536"), contact finish thickness (50.0µin), and contact material (Copper Alloy) specifications identically to the SI-50076-F.

Q: Are all substitute parts RoHS compliant?

A: Yes. The SI-50076-F, 0816-1X1T-23-F, and 7499111000A are ROHS3 Compliant. The JK0-0187NL is RoHS Compliant. All parts satisfy regulatory requirements for restricted substance elimination.
