Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-6388-FLS-50 is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (8P8C/RJ45 jack)
• Physical orientation (90° right-angle)
• Mounting method (through-hole solder termination)
• Shielding classification (unshielded)
• Port and row configuration (1 port, 1 row)
• Housing and contact materials (thermoplastic, copper alloy with gold finish)
• Operating temperature range (-40°C to 85°C)
• Mechanical features (board lock, panel stops)

The SS-6488-FLS qualifies as a direct substitute based on full alignment with these parameters. Both connectors are manufactured by Stewart Connector and maintain identical electrical and mechanical specifications for the core functional requirements.

Engineering Selection Recommendations

The SS-6488-FLS is the manufacturer-recommended substitute for the obsolete SS-6388-FLS-50. Selection of the substitute part is supported by the following factors:

• The SS-6488-FLS maintains active product status with Stewart Connector, ensuring ongoing availability and supply chain continuity.
• Both parts are REACH Unaffected and classified under identical ECCN and HTSUS codes, confirming regulatory equivalence.
• The SS-6488-FLS carries RoHS3 compliance certification, meeting current environmental and hazardous substance restrictions.
• Electrical and mechanical specifications are fully aligned across all critical parameters, including contact configuration, orientation, termination method, and operating temperature range.
• The substitute part is available in higher inventory quantities (2457 pcs vs. 1102 pcs), supporting procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the SS-6488-FLS be used as a direct replacement for the SS-6388-FLS-50 in existing designs?

A: Yes. The SS-6488-FLS is electrically and mechanically equivalent to the SS-6388-FLS-50 across all functional parameters. Both connectors share identical 8P8C contact configuration, 90° right-angle orientation, through-hole solder termination, and operating specifications. No design modifications are required for substitution.

Q: What is the difference in contact finish thickness between these parts?

A: The SS-6388-FLS-50 specifies a contact finish thickness of 50.0µin (1.27µm), while the SS-6488-FLS specifies 30.0µin (0.76µm). Both thicknesses meet the functional requirements for 8P8C modular connectors and maintain gold contact finish properties. The difference reflects manufacturing process variations between series generations and does not affect electrical performance or compatibility.

Q: Are there packaging differences between the main part and substitute?

A: The SS-6388-FLS-50 packaging is not specified in the available data. The SS-6488-FLS is supplied in tube packaging. Confirm packaging requirements with your procurement or assembly process specifications.

Q: Why is the SS-6388-FLS-50 classified as obsolete?

A: The SS-6388-FLS-50 belongs to Stewart Connector's Series 63 product line, which has been superseded by the Series 64 line (SS-6488-FLS). The manufacturer recommends transitioning to the newer series for new designs and ongoing production support.

Q: Does the SS-6488-FLS meet current compliance standards?

A: Yes. The SS-6488-FLS is RoHS3 compliant and maintains REACH Unaffected status, meeting current environmental and regulatory requirements. The SS-6388-FLS-50 compliance status is not specified in the available data.
