Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-50141-F is determined by the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port only
• Mounting & Orientation: Through hole, 90° right angle orientation
• Termination Method: Solder termination required
• Physical Dimensions: Height above board 0.550" (13.97mm) to ensure PCB clearance compatibility
• Electrical Characteristics: Shielded construction with gold-plated contacts for signal integrity
• Environmental Compliance: RoHS compliance and MSL 1 rating for moisture sensitivity

The substitute part J1026F01PNL from Pulse Electronics meets these core substitution criteria across all mandatory parameters, enabling direct functional replacement in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SI-50141-F and J1026F01PNL are Active status products with full regulatory compliance. The SI-50141-F carries ROHS3 compliance, while the J1026F01PNL meets RoHS requirements. Both components are REACH Unaffected and classified under ECCN EAR99. Selection between these parts should be based on availability, lead time, packaging format (Tube for J1026F01PNL), and inventory levels. The J1026F01PNL offers higher inventory availability (4300 pieces) compared to SI-50141-F (971 pieces), making it suitable for high-volume production requirements. Both connectors maintain identical mechanical and electrical interface specifications for direct PCB integration.

Frequently Asked Questions (FAQ)

Q: Can J1026F01PNL replace SI-50141-F in existing designs? A: Yes. Both connectors share identical mounting type (Through Hole), orientation (90° Right), height above board (0.550"), termination method (Solder), and shielding configuration. The RJ45 connector type and single-port configuration are equivalent across both parts.

Q: Are there differences in contact material between these parts? A: Yes. SI-50141-F uses Copper Alloy contacts, while J1026F01PNL uses Phosphor Bronze contacts. Both are gold-plated for signal integrity. The contact finish thickness differs: SI-50141-F at 50.0µin (1.27µm) versus J1026F01PNL at 15.0µin (0.38µm).

Q: What is the difference in shield material? A: SI-50141-F uses Copper Alloy shielding, while J1026F01PNL uses Brass shielding. Both provide equivalent electromagnetic shielding performance for 10/100 Base-T applications.

Q: Do both parts support the same applications? A: SI-50141-F supports 10/100 Base-T with AutoMDIX. J1026F01PNL supports 10/100 Base-TX. Both are suitable for equivalent Ethernet networking applications at these speed ratings.

Q: What is the operating temperature range for each part? A: SI-50141-F does not specify an operating temperature range in the provided data. J1026F01PNL operates from 0°C to 70°C.

Q: Are there packaging differences? A: SI-50141-F packaging is not specified. J1026F01PNL is supplied in Tube packaging, suitable for automated assembly processes.
