Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3-406549-3 with the Amphenol ICC RJHSE5388 is based on alignment of the following critical parameters:

Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold, 50.0µin (1.27µm)
• Housing Material: Thermoplastic
• Tab Direction: Up
• LED Color: Green-Red
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8536.69.4040

These parameters define the functional and mechanical compatibility required for direct substitution in through-hole solder applications requiring shielded 8p8c modular jack connectors.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC RJHSE5388 serves as a direct functional substitute for the obsolete TE Connectivity 3-406549-3. Both connectors meet identical electrical and mechanical specifications for 8p8c shielded modular jack applications with through-hole solder termination.

Product Status Consideration: The RJHSE5388 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 3-406549-3.

Compliance Alignment: Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, supporting regulatory and export requirements.

Operating Temperature: The RJHSE5388 extends the minimum operating temperature to -55°C compared to the 3-406549-3 at -40°C, providing broader thermal performance capability while maintaining the upper limit of 85°C.

Mechanical Features Distinction: The 3-406549-3 incorporates a board guide feature, while the RJHSE5388 includes board lock functionality. Both features provide mechanical retention; the selection between them depends on specific board design requirements and assembly process compatibility.

Contact and Finish Specifications: Identical phosphor bronze contact material with 50.0µin (1.27µm) gold finish ensures equivalent electrical performance and signal integrity for Cat5 Ethernet applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC RJHSE5388 directly replace the TE Connectivity 3-406549-3 in existing designs?

A: Yes. Both connectors share identical specifications for connector type, contact configuration (8p8c), orientation (90° right-angle), mounting method (through-hole solder), shielding design (EMI finger), contact materials, and finish specifications. The primary design consideration is the difference between board guide (3-406549-3) and board lock (RJHSE5388) features, which must be evaluated against specific PCB layout and assembly requirements.

Q: What is the significance of the operating temperature range difference?

A: The RJHSE5388 operates from -55°C to 85°C, while the 3-406549-3 operates from -40°C to 85°C. The RJHSE5388 provides extended low-temperature capability. For applications operating within the -40°C to 85°C range, both connectors are functionally equivalent. Applications requiring operation below -40°C must use the RJHSE5388.

Q: Are there packaging differences between these connectors?

A: The 3-406549-3 packaging specification is not provided in the technical data. The RJHSE5388 is supplied in tray packaging. Packaging format should be confirmed with the supplier based on procurement and assembly requirements.

Q: Do both connectors support Cat5 Ethernet applications?

A: The 3-406549-3 is explicitly rated for Cat5. The RJHSE5388 does not specify a category rating in the provided data. Both connectors feature identical 8p8c shielded jack configuration with EMI finger design and equivalent contact specifications suitable for Ethernet applications. Category rating confirmation for the RJHSE5388 should be obtained from the manufacturer if specific category certification is required.

Q: What is the difference between board guide and board lock features?

A: Board guide (3-406549-3) provides alignment assistance during assembly. Board lock (RJHSE5388) provides mechanical retention after installation. The selection depends on PCB design, assembly process, and whether post-installation connector retention is required.

Q: Are both connectors RoHS compliant?

A: Yes. The 3-406549-3 is ROHS3 compliant. The RJHSE5388 is RoHS compliant. Both meet RoHS requirements for lead-free and restricted substance compliance.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
