RJ11-2LC2-S Equivalent & Substitute Parts

Part Overview

The RJ11-2LC2-S is a modular jack connector manufactured by TE Connectivity Corcom Filters, designed for 6-position 2-contact (6p2c) RJ11 applications. This connector features a 90° right-angle orientation with shielding, through-hole mounting, and solder termination. The product is classified as obsolete, necessitating identification of active equivalent components for ongoing procurement and design requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJ11-2LC2-S is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Connector type: Jack
• Contact configuration: 6p2c (RJ11)
• Contact finish: Gold plating
• Shielding: Shielded construction

Mechanical Compatibility Parameters:

• Orientation: 90° angle (right)
• Mounting type: Through hole
• Termination method: Solder
• Tab direction: Down
• Number of ports: 1
• Number of rows: 1

Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level (MSL): 1 (Unlimited)
• ECCN classification: EAR99

The substitute part SS-7026-NF meets all critical electrical and mechanical parameters required for direct substitution. Both parts share identical connector configuration, orientation, mounting methodology, and termination approach, ensuring functional equivalence in circuit board applications.

Parameter Comparison

Engineering Selection Recommendations

The SS-7026-NF manufactured by Stewart Connector is the direct functional equivalent for the obsolete RJ11-2LC2-S. Selection of this substitute is based on the following engineering criteria:

Compliance and Regulatory Status: The SS-7026-NF holds ROHS3 compliance, representing current regulatory standards, whereas the RJ11-2LC2-S is classified as RoHS Compliant (earlier standard). Both components maintain EAR99 export classification and identical HTSUS tariff codes, confirming regulatory equivalence.

Product Availability: The RJ11-2LC2-S is obsolete with limited remaining inventory (918 pieces). The SS-7026-NF is active in production with substantially higher inventory availability (3453 pieces), ensuring long-term procurement viability.

Electrical and Mechanical Equivalence: Both connectors maintain identical specifications for connector type, contact configuration (6p2c RJ11), orientation (90° right angle), mounting methodology (through hole), and termination approach (solder). Shielding, port count, row configuration, and tab direction are identical across both parts.

Material and Performance Considerations: Contact finish thickness differs between parts (50.0µin versus 30.0µin), with the RJ11-2LC2-S providing greater gold plating depth. Housing materials differ (polyester glass-filled versus thermoplastic) and contact base materials differ (phosphor bronze versus copper alloy). These material variations do not affect functional compatibility in standard RJ11 jack applications.

Moisture Sensitivity: Both components maintain MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the SS-7026-NF directly replace the RJ11-2LC2-S in existing circuit board designs?

A: Yes. Both connectors share identical electrical and mechanical specifications for connector type, contact configuration, orientation, mounting type, and termination method. Direct substitution is supported without design modification.

Q: What are the differences in contact plating between these two parts?

A: The RJ11-2LC2-S features 50.0µin (1.27µm) gold contact finish thickness, while the SS-7026-NF features 30.0µin (0.76µm) thickness. Both maintain gold finish composition. The thickness difference reflects manufacturing process variations between manufacturers and does not affect electrical performance in standard RJ11 applications.

Q: Are there differences in housing material between these connectors?

A: Yes. The RJ11-2LC2-S uses polyester glass-filled housing material, while the SS-7026-NF uses thermoplastic housing. Both materials provide adequate mechanical support and environmental protection for through-hole mounted modular connectors. Material selection does not affect functional compatibility.

Q: What is the significance of the product status difference?

A: The RJ11-2LC2-S is classified as obsolete, indicating discontinued production and limited remaining inventory. The SS-7026-NF is active in production, ensuring ongoing availability for new designs and replacement requirements. For applications requiring long-term component availability, the SS-7026-NF is the appropriate selection.

Q: Do both connectors meet current regulatory compliance standards?

A: Both connectors maintain RoHS compliance. The SS-7026-NF holds ROHS3 certification, representing the current regulatory standard. The RJ11-2LC2-S holds RoHS Compliant status (earlier standard). Both meet export classification requirements under EAR99 and share identical HTSUS tariff codes.

Q: What is the packaging difference between these parts?

A: The RJ11-2LC2-S packaging information is not specified in available documentation. The SS-7026-NF is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Are there operating temperature specifications for these connectors?

A: Operating temperature specification is not provided for the RJ11-2LC2-S. The SS-7026-NF operates across the temperature range of -40°C to 85°C. This specification does not affect substitution compatibility for standard indoor applications.

Q: What contact base materials are used in each connector?

A: The RJ11-2LC2-S uses phosphor bronze contact material, while the SS-7026-NF uses copper alloy contact material. Both materials provide adequate electrical conductivity and mechanical durability for RJ11 jack applications. Material composition does not affect functional compatibility.
