Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 90598-101 is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Number of Ports: 1
• Number of Rows: 1
• Mounting Type: Through Hole
• Orientation: Vertical
• Termination: Solder

Performance and Environmental Parameters:

• Operating Temperature Range: Minimum -40°C capability required
• Moisture Sensitivity Level: 1 (Unlimited)
• Contact Finish: Gold plating

The Molex 0855075002 satisfies all core compatibility parameters. While this substitute introduces shielding (Shielded vs. Unshielded) and upgrades the performance rating to Cat5e, these represent functional enhancements rather than incompatibilities. The shielded design provides superior electromagnetic interference rejection suitable for modern Ethernet installations, and Cat5e rating encompasses Cat3 performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0855075002 is the qualified substitute for the obsolete Amphenol ICC 90598-101. Selection rationale is based on the following factors:

Product Status: The 90598-101 is obsolete, making the active-status 0855075002 the appropriate long-term solution for new designs and ongoing production support.

Compliance and Certifications: The 0855075002 achieves ROHS3 compliance, addressing regulatory requirements that the non-compliant 90598-101 does not meet. Both connectors maintain EAR99 export classification and identical HTSUS coding (8536.69.4040).

Functional Compatibility: All core mechanical and electrical parameters align. The upgrade from Cat3 to Cat5e performance rating and the addition of shielding represent functional improvements that maintain backward compatibility with Cat3 applications while providing enhanced performance for modern Ethernet infrastructure.

Environmental Performance: The 0855075002 extends the operating temperature range to 85°C, providing additional thermal margin compared to the 70°C maximum of the 90598-101.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0855075002 directly replace the Amphenol ICC 90598-101 in existing designs?

A: Yes. Both connectors share identical core specifications: 8p8c jack configuration, vertical through-hole solder termination, single port, and single row layout. The mechanical footprint and pin assignment are compatible.

Q: What is the significance of the shielding difference between these connectors?

A: The 90598-101 is unshielded; the 0855075002 is shielded. Shielding provides electromagnetic interference rejection. For applications in electromagnetically clean environments, both perform equivalently. For environments with EMI sources, the shielded 0855075002 offers superior performance. Shielding does not degrade performance in unshielded applications.

Q: Why does the performance rating differ (Cat3 vs. Cat5e)?

A: Cat3 and Cat5e are Ethernet performance categories defined by transmission frequency and signal integrity specifications. Cat5e encompasses and exceeds Cat3 performance. The 0855075002 Cat5e rating indicates capability for higher-frequency applications. Cat3 applications operate within Cat5e specifications without modification.

Q: Are there packaging differences between these parts?

A: The 90598-101 packaging is not specified in available data. The 0855075002 is supplied in Tray packaging. Confirm packaging requirements with your procurement process.

Q: What is the difference in contact finish thickness?

A: The 90598-101 specifies 5.00µin (0.127µm) gold plating. The 0855075002 specifies Flash gold plating, which is a thin electrodeposited layer. Both provide adequate contact resistance and wear characteristics for modular connector applications. Flash plating is standard for modern connector designs.

Q: Does the extended operating temperature range of the 0855075002 affect compatibility?

A: No. The 0855075002 operates from -40°C to 85°C, while the 90598-101 operates from -40°C to 70°C. The substitute's wider range provides additional thermal margin and does not create incompatibility with applications designed for the narrower range.

Q: Are both connectors RoHS compliant?

A: The 90598-101 is RoHS non-compliant. The 0855075002 is ROHS3 compliant. For applications subject to RoHS regulations, the 0855075002 is required. For legacy systems without RoHS requirements, both are functionally equivalent.
