SS-6488-NF-SB00 Equivalent & Substitute Parts

Part Overview

The SS-6488-NF-SB00 is a modular jack connector manufactured by Stewart Connector, designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and shielded construction. This connector features through-hole solder termination and is rated for operating temperatures between -40°C and 85°C. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-6488-NF-SB00 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Must be a jack connector with 8p8c (RJ45, Ethernet) contact arrangement
• Physical Orientation: Must maintain 90° right-angle mounting orientation
• Mounting & Termination: Must support through-hole solder termination
• Electrical Characteristics: Contact material, finish type, and finish thickness must be compatible with the original specification
• Environmental Ratings: Operating temperature range and moisture sensitivity must meet or exceed the original ratings
• Shielding Consideration: Shielded construction is a defining characteristic of the SS-6488-NF-SB00

The identified substitute part (5557788-1) shares the core mechanical and electrical interface characteristics but differs in shielding configuration, which represents a functional trade-off requiring application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The 5557788-1 from TE Connectivity AMP Connectors is mechanically and electrically compatible with the SS-6488-NF-SB00 for through-hole solder applications requiring 8p8c (RJ45, Ethernet) jack connectors with 90° right-angle orientation. Both connectors share identical operating temperature ranges (-40°C ~ 85°C), moisture sensitivity ratings (MSL 1), and contact finish specifications (gold, 50.0µin thickness).

The primary distinction is shielding configuration: the SS-6488-NF-SB00 provides shielded construction, while the 5557788-1 is unshielded with Cat3 rating. The 5557788-1 is currently in active production status with RoHS compliance certification, whereas the original part is obsolete. Selection between these parts depends on whether electromagnetic shielding is required for the application. If shielding is mandatory, alternative shielded 8p8c jack connectors from active manufacturers should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the 5557788-1 directly replace the SS-6488-NF-SB00 in all applications?

A: The 5557788-1 is mechanically and electrically compatible for through-hole solder termination and shares identical contact finish specifications and operating temperature ratings. However, the unshielded design of the 5557788-1 differs from the shielded construction of the SS-6488-NF-SB00. Applications requiring electromagnetic shielding must evaluate whether unshielded operation is acceptable.

Q: What are the key compatibility criteria for substitution?

A: Substitution requires matching connector type (jack), contact configuration (8p8c RJ45), orientation (90° right-angle), mounting method (through-hole), and termination type (solder). Contact finish specifications and operating temperature ranges must be equivalent or superior.

Q: Does the difference in contact material (Copper Alloy vs. Phosphor Bronze) affect compatibility?

A: Both materials are standard for modular connector applications and are compatible with gold plating at the specified thickness (50.0µin / 1.27µm). The contact finish thickness is identical, ensuring equivalent electrical performance.

Q: What is the significance of the Cat3 rating on the 5557788-1?

A: Cat3 (Category 3) is a telecommunications standard for unshielded twisted pair cabling, indicating the connector's performance classification for data transmission. This rating applies to the unshielded configuration of the 5557788-1.

Q: Are there compliance differences between these parts?

A: The 5557788-1 carries RoHS compliance certification and is in active production. The SS-6488-NF-SB00 is obsolete. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications and are REACH unaffected.

Q: What packaging considerations apply to the 5557788-1?

A: The 5557788-1 is supplied in tray packaging, whereas the SS-6488-NF-SB00 packaging specification is not provided. Verify packaging requirements for your procurement and assembly processes.
