SS-7046-NF-50 Equivalent & Substitute Parts

Part Overview

The SS-7046-NF-50 is a modular jack connector manufactured by Stewart Connector, designed for 6p4c (RJ11, RJ14) applications with 90° right-angle orientation and through-hole solder termination. This connector features board lock functionality and unshielded construction with gold-plated copper alloy contacts.

The SS-7046-NF-50 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS-7046-NF-50 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Connector type: Jack
• Contact configuration: 6p4c (RJ11, RJ14)
• Mounting method: Through hole
• Orientation: 90° angle (right)
• Termination method: Solder
• Shielding: Unshielded
• Port and row configuration: 1 port, 1 row
• Board lock feature: Present

Secondary Compatibility Criteria:

• Contact finish: Gold plating
• Tab direction: Down
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all primary criteria and secondary criteria are classified as direct substitutes. Variations in contact material, contact finish thickness, housing material composition, and operating temperature range do not preclude substitution when all primary and secondary parameters align.

Parameter Comparison

Engineering Selection Recommendations

SS-7046-NF (Stewart Connector): This part is the direct successor within the Stewart Connector 70 series. It maintains identical mechanical and electrical specifications to the obsolete SS-7046-NF-50 while offering active product status and RoHS3 compliance. This part is recommended as the primary replacement option for new designs and ongoing production.

215876-2 (TE Connectivity AMP Connectors): This part provides cross-manufacturer compatibility with identical connector configuration and mechanical interface. It is manufactured by TE Connectivity, a major connector supplier, and carries active product status with RoHS compliance. The housing material differs (PBT versus thermoplastic) and operating temperature range is specified (-40°C ~ 70°C). This part serves as an alternative substitute when Stewart Connector parts are unavailable.

Both substitute parts satisfy all primary and secondary compatibility criteria. Selection between them should be based on supply chain availability, lead time requirements, and any design-specific preferences regarding manufacturer or material composition.

Frequently Asked Questions (FAQ)

Q: Can SS-7046-NF be used as a direct replacement for SS-7046-NF-50?

A: Yes. Both parts share identical connector type, contact configuration (6p4c RJ11/RJ14), mounting method (through hole), orientation (90° right angle), termination (solder), shielding (unshielded), and board lock feature. The primary difference is product status: SS-7046-NF is active while SS-7046-NF-50 is obsolete. SS-7046-NF is the recommended replacement.

Q: What are the key differences between the Stewart Connector and TE Connectivity substitutes?

A: Both parts meet all primary compatibility criteria. Differences include: manufacturer (Stewart Connector versus TE Connectivity), housing material (thermoplastic versus PBT), contact material (copper alloy versus phosphor bronze), and specified operating temperature range (TE Connectivity specifies -40°C ~ 70°C). These differences do not affect functional compatibility for standard 6p4c modular jack applications.

Q: Are there packaging differences between these parts?

A: Yes. SS-7046-NF-50 packaging is not specified. SS-7046-NF is supplied in bulk packaging. 215876-2 is supplied in cut tape (CT) packaging. Packaging selection should align with procurement and assembly requirements.

Q: Do all substitute parts meet RoHS compliance?

A: SS-7046-NF is RoHS3 compliant. 215876-2 is RoHS compliant. RoHS status for the original SS-7046-NF-50 is not specified in available documentation.

Q: Is the difference in contact finish thickness significant?

A: SS-7046-NF-50 specifies 50.0µin (1.27µm) gold plating. SS-7046-NF specifies 30.0µin (0.76µm). Both thicknesses provide adequate contact durability for modular jack applications. The 215876-2 contact finish thickness is not specified. These variations do not preclude substitution.

Q: Can these parts be used in Cat3 rated applications?

A: 215876-2 is rated for Cat3 applications. SS-7046-NF and SS-7046-NF-50 ratings are not specified. For applications requiring Cat3 certification, 215876-2 is the appropriate selection.
