SS-6388-NF Equivalent & Substitute Parts

Part Overview

The SS-6388-NF is a modular jack connector manufactured by Stewart Connector, designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and through-hole solder termination. This connector features an unshielded design with board lock functionality and operates across the -40°C to 85°C temperature range.

The SS-6388-NF is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS-6388-NF are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Connector type (Jack)
• Contact configuration (8p8c / RJ45, Ethernet)
• Mounting method (Through Hole)
• Orientation (90° Angle, Right)
• Termination method (Solder)
• Shielding classification (Unshielded)
• Contact material and finish specifications (Copper Alloy, Gold plated)
• Operating temperature range (-40°C ~ 85°C)
• Board lock feature presence

All identified substitutes maintain these core parameters, ensuring functional and mechanical compatibility with applications designed for the SS-6388-NF.

Parameter Comparison

Engineering Selection Recommendations

Both SS-6488-NF and SS63800-004G are active product alternatives to the obsolete SS-6388-NF, with identical electrical and mechanical specifications.

SS-6488-NF represents the direct series progression from the SS-6388-NF, transitioning from Series 63 to Series 64 while maintaining all functional parameters. This part carries ROHS3 compliance certification and is available in tube packaging with higher inventory levels (2260 units).

SS63800-004G remains within Series 63 and includes the EPP918A feature designation. This part also carries ROHS3 compliance certification and maintains Series 63 compatibility for applications requiring series-level consistency.

Both substitutes satisfy REACH and ECCN (EAR99) requirements equivalent to the original part. Selection between these alternatives depends on series preference and packaging requirements for your application.

Frequently Asked Questions (FAQ)

Q: Are SS-6488-NF and SS63800-004G fully interchangeable with SS-6388-NF?

A: Both parts maintain identical electrical and mechanical parameters including connector type, contact configuration, mounting method, orientation, termination, shielding, contact material and finish, housing material, and operating temperature range. They are functionally equivalent for applications designed for the SS-6388-NF.

Q: What is the difference between Series 63 and Series 64?

A: SS-6488-NF (Series 64) and SS63800-004G (Series 63) represent different product series within Stewart Connector's modular connector lineup. Both meet the same electrical and mechanical specifications for 8p8c RJ45 Ethernet jack connectors with 90° right-angle orientation. Series selection depends on design requirements and supply chain preferences.

Q: Does packaging affect substitution compatibility?

A: Packaging format (tube for SS-6488-NF versus unspecified for SS63800-004G) does not affect electrical or mechanical compatibility. Packaging selection is determined by procurement, handling, and storage requirements rather than functional performance.

Q: Are both substitutes RoHS compliant?

A: Yes. Both SS-6488-NF and SS63800-004G carry ROHS3 compliance certification. The original SS-6388-NF does not specify RoHS status.

Q: What does the EPP918A feature on SS63800-004G indicate?

A: EPP918A is a feature designation specific to SS63800-004G. Both parts maintain identical core specifications for 8p8c RJ45 jack connector applications.
