Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-50195-F is determined by strict alignment of the following critical parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Height Above Board: 0.550" (13.97mm)
• LED Color: Green - Green
• Number of Cores per Jack: 4
• Shielding: Shielded, EMI Finger
• Features: Board Guide
• Tab Direction: Up
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Status: ROHS3 Compliant or equivalent
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The J1012F21KNL from Pulse Electronics meets these substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can J1012F21KNL be used as a direct replacement for SI-50195-F?

A: Yes. Both parts share identical critical parameters including connector type, port configuration, mounting method, orientation, termination style, board height, LED indicators, core count, shielding, and contact finish specifications.

Q: Are there differences in contact material between these parts?

A: Yes. The SI-50195-F uses Copper Alloy contacts, while the J1012F21KNL uses Phosphor Bronze contacts. Both materials are suitable for the specified 10/100 Base-T and Base-TX applications.

Q: What is the difference between the shield materials?

A: The SI-50195-F uses Copper Alloy shielding, while the J1012F21KNL uses Brass shielding. Both provide equivalent EMI protection for the specified applications.

Q: Do these parts have different contact finish thicknesses?

A: Yes. The SI-50195-F specifies 50.0µin (1.27µm) contact finish thickness, while the J1012F21KNL specifies 15.0µin (0.38µm). Both thicknesses are within acceptable ranges for gold-plated contacts in this connector category.

Q: What is the operating temperature range for each part?

A: The SI-50195-F does not specify an operating temperature range in the provided data. The J1012F21KNL specifies 0°C ~ 70°C operating temperature.

Q: Are both parts available in the same packaging?

A: The SI-50195-F packaging is not specified in the provided data. The J1012F21KNL is available in Tube packaging with 1073 pieces in new original inventory.
