Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0826-1B1T-43-F is determined by the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port, 8-core jack
• Mounting & Orientation: Through-hole PCB mount, 90° right-angle orientation
• Electrical Performance: 10/100/1000 Base-T with AutoMDIX support
• Shielding & EMI Protection: Shielded construction with EMI finger
• Termination Method: Solder termination for PCB integration
• Contact Material & Finish: Gold-plated contacts for reliable signal transmission
• Operating Temperature Range: 0°C to 70°C
• Compliance Status: RoHS and REACH compliance

The substitute part JK0-0136NL from Pulse Electronics meets all critical functional and mechanical parameters, enabling direct substitution in applications requiring equivalent electrical performance and physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 0826-1B1T-43-F and JK0-0136NL are active production parts with full regulatory compliance. The 0826-1B1T-43-F carries ROHS3 certification, while the JK0-0136NL is RoHS compliant. Both parts maintain REACH unaffected status and share identical ECCN and HTSUS classifications.

The primary differentiation lies in packaging format and minor physical dimensions. The 0826-1B1T-43-F is supplied in standard packaging, while the JK0-0136NL is available in tray packaging. The height above board differs by 0.010" (0.26mm), which is negligible for most PCB layout applications. Contact material composition differs (Copper Alloy vs. Phosphor Bronze) and contact finish thickness varies (50.0µin vs. 30.0µin), but both configurations deliver equivalent electrical performance within the specified operating parameters.

Selection should be based on supply availability, packaging requirements, and inventory status. Both parts are suitable for direct substitution in 10/100/1000 Base-T Ethernet applications requiring shielded RJ45 connectivity with AutoMDIX support.

Frequently Asked Questions (FAQ)

Q: Can JK0-0136NL be used as a direct replacement for 0826-1B1T-43-F?

A: Yes. Both connectors share identical functional specifications for RJ45 through-hole PCB mounting, 10/100/1000 Base-T operation with AutoMDIX, solder termination, and shielded EMI protection. The 0.010" height difference is within typical PCB design tolerances.

Q: What is the difference in packaging between these two parts?

A: The 0826-1B1T-43-F uses standard packaging, while the JK0-0136NL is supplied in tray packaging. Tray packaging is suitable for automated assembly processes and bulk handling.

Q: Are both parts RoHS compliant?

A: Yes. The 0826-1B1T-43-F is ROHS3 compliant, and the JK0-0136NL is RoHS compliant. Both meet regulatory requirements for lead-free manufacturing.

Q: Do the different contact materials affect electrical performance?

A: No. Both Copper Alloy and Phosphor Bronze contacts with gold plating deliver equivalent electrical conductivity and signal integrity for Ethernet applications. The contact finish thickness difference (50.0µin vs. 30.0µin) does not impact functional performance within the specified operating temperature range.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on supply chain availability, packaging preference, and inventory status. Both parts are active production items with equivalent electrical and mechanical compatibility.
