Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4RJ11-6L-B is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 6p6c (RJ11, RJ12, RJ14, RJ25)
• Orientation: 90° Angle (Right)
• Shielding: Unshielded
• Mounting Type: Through Hole
• Termination: Solder

The substitute part SS-666604-NF meets all mandatory matching parameters and is therefore classified as a direct functional equivalent. Both connectors share identical electrical and mechanical interface specifications, enabling interchangeability in applications requiring 6-position modular jack connectors with right-angle through-hole solder termination.

Engineering Selection Recommendations

Primary Part: 4RJ11-6L-B

The 4RJ11-6L-B remains the preferred selection when available. This part is manufactured by TE Connectivity Corcom Filters and maintains active inventory status with 720 units in stock.

Substitute Part: SS-666604-NF

The SS-666604-NF manufactured by Stewart Connector is a qualified substitute when the primary part is unavailable. This substitute meets all mandatory electrical and mechanical interface requirements for direct replacement. The SS-666604-NF carries ROHS3 compliance certification and REACH unaffected status, confirming regulatory alignment with current environmental standards. The part is currently classified as obsolete; however, 903 units remain available in inventory. Selection of this substitute should account for its obsolete status and confirm long-term availability requirements for production planning.

Frequently Asked Questions (FAQ)

Q: Can SS-666604-NF be used as a direct replacement for 4RJ11-6L-B?

A: Yes. Both connectors share identical specifications for connector type (jack), contact configuration (6p6c), orientation (90° right angle), shielding (unshielded), mounting method (through hole), and termination (solder). They are functionally equivalent for applications requiring these specifications.

Q: What is the significance of the obsolete status for SS-666604-NF?

A: The obsolete designation indicates that Stewart Connector has discontinued active production of this part. However, existing inventory of 903 units is available for current procurement. For applications requiring long-term supply assurance, verification of extended availability should be conducted before committing to this substitute for high-volume or long-lifecycle applications.

Q: Are there differences in contact materials or finishes between these parts?

A: The SS-666604-NF specifies copper alloy contacts with gold finish at 30.0µin (0.76µm) thickness. The 4RJ11-6L-B contact material and finish specifications are not provided in the available documentation. Both parts are suitable for standard modular connector applications; however, contact material and finish specifications should be verified against application requirements if corrosion resistance or specific electrical properties are critical.

Q: What compliance certifications apply to these parts?

A: The SS-666604-NF carries ROHS3 compliance and REACH unaffected status. Compliance information for the 4RJ11-6L-B is not provided in the available documentation. Applications subject to regulatory compliance requirements should verify certification status for the selected part.

Q: Are there packaging differences between these parts?

A: The 4RJ11-6L-B packaging specification is not provided. The SS-666604-NF is supplied in bulk packaging. Packaging format should be confirmed during procurement to ensure compatibility with assembly and inventory management processes.
