Substitute Part Grouping Explanation

Equivalent substitution for the 1840784-1 is determined by strict alignment of core electrical and mechanical parameters. The substitute part JK0-0136NL qualifies as an equivalent based on the following criteria:

Critical Matching Parameters:

• Connector Type: RJ45 (identical)
• Number of Ports: 1 (identical)
• Applications: 10/100/1000 Base-T, AutoMDIX (identical)
• Mounting Type: Through Hole (identical)
• Orientation: 90° Angle (Right) (identical)
• Termination: Solder (identical)
• Number of Cores per Jack: 8 (identical)
• Shielding: Shielded, EMI Finger (identical)
• Contact Material: Phosphor Bronze (identical)
• Contact Finish: Gold (identical)
• Operating Temperature: 0°C ~ 70°C (identical)
• Shield Material: Brass (identical)
• Housing Material: Thermoplastic (identical)
• RoHS Compliance: Both compliant (RoHS3 and RoHS Compliant)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

All parameters that define functional and mechanical compatibility are identical between the main part and substitute, establishing direct equivalence for component selection purposes.

Parameter Comparison

Engineering Selection Recommendations

Both the 1840784-1 and JK0-0136NL are Active status products with full regulatory compliance. The 1840784-1 carries RoHS3 certification, while the JK0-0136NL carries RoHS compliance. Both maintain REACH Unaffected status and identical ECCN/HTSUS classifications, confirming regulatory equivalence for procurement and deployment.

The primary differences between these parts are non-functional in nature: LED color indication (Green/Orange versus Yellow/Green), height variance of 0.010" (0.26mm), contact finish thickness differential (50.0µin versus 30.0µin), and feature set (1840784-1 includes decoupling capacitance while JK0-0136NL does not). These variations do not affect electrical performance, mechanical compatibility, or thermal operating range.

Selection between these equivalent parts should be based on inventory availability, lead time requirements, and specific application needs regarding LED color indication or decoupling capacitance integration.

Frequently Asked Questions (FAQ)

Q: Are the 1840784-1 and JK0-0136NL electrically interchangeable?

A: Yes. Both connectors support identical 10/100/1000 Base-T Ethernet applications with AutoMDIX functionality, operate across the same temperature range (0°C ~ 70°C), and feature identical core electrical specifications including 8-core RJ45 configuration, phosphor bronze contacts with gold finish, and shielded EMI finger design.

Q: What is the significance of the height difference between these parts?

A: The 1840784-1 has a height above board of 0.536" (13.61mm) while the JK0-0136NL measures 0.546" (13.87mm), a difference of 0.010" (0.26mm). This minor variance may be relevant only in applications with strict vertical clearance constraints. For standard PCB layouts, this difference is not functionally significant.

Q: Does the contact finish thickness difference affect performance?

A: The 1840784-1 features 50.0µin (1.27µm) gold plating while the JK0-0136NL has 30.0µin (0.76µm). Both thicknesses meet industry standards for RJ45 connectors and provide equivalent contact durability and electrical performance for the specified operating conditions.

Q: Why does the 1840784-1 include decoupling capacitance while the JK0-0136NL does not?

A: The 1840784-1 MagJack® series integrates decoupling capacitance as an integrated feature, while the PULSEJACK™ JK0 series does not. This difference does not affect interchangeability for standard Ethernet applications. Applications requiring integrated decoupling should specify the 1840784-1.

Q: Are both parts RoHS compliant?

A: Yes. The 1840784-1 is RoHS3 Compliant and the JK0-0136NL is RoHS Compliant. Both meet regulatory requirements for hazardous substance restrictions. Both maintain REACH Unaffected status.

Q: Can these connectors be used in the same PCB design without layout modifications?

A: Yes. Both connectors share identical mounting type (Through Hole), orientation (90° Angle Right), termination method (Solder), and core mechanical specifications. The 0.010" height difference is negligible for standard PCB designs. No layout modifications are required for substitution.

Q: What is the packaging format for both parts?

A: Both the 1840784-1 and JK0-0136NL are supplied in Tray packaging, suitable for automated assembly and standard component handling procedures.
