RJ11-2L-S Equivalent & Substitute Parts

Part Overview

The RJ11-2L-S is a modular jack connector manufactured by TE Connectivity Corcom Filters, designed for 6-position 2-contact (6p2c) RJ11 applications. This through-hole mounted connector features a 90° right-angle orientation with unshielded construction and solder termination. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJ11-2L-S is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 6p2c (RJ11)
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Unshielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Contact Finish Thickness: 50.0µin (1.27µm)
• Tab Direction: Down

The substitute part 0432026107 (Molex) satisfies all mandatory matching parameters, establishing functional equivalence for direct replacement in applications requiring RJ11-2L-S specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RJ11-2L-S and 0432026107 are classified as obsolete products. The Molex 0432026107 provides functional equivalence with enhanced compliance status (ROHS3 Compliant versus RoHS Compliant) and defined operating temperature range (-40°C ~ 85°C). The Molex substitute maintains identical electrical and mechanical specifications across all critical parameters, including contact material, finish thickness, and connector geometry.

Selection between these parts should be based on availability, packaging requirements (Tray for Molex versus unspecified for TE Connectivity), and compliance certifications applicable to the end application. Both parts carry EAR99 ECCN classification and identical HTSUS codes.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0432026107 directly replace the TE Connectivity RJ11-2L-S?

A: Yes. The 0432026107 matches all critical electrical and mechanical parameters of the RJ11-2L-S, including connector type, contact configuration, mounting method, orientation, termination style, and contact specifications. Direct substitution is supported for applications requiring 6p2c RJ11 jack connectors with 90° right-angle solder termination.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer identity, housing material composition (Polyester Glass Filled versus Polyamide Nylon Glass Filled), packaging format (unspecified versus Tray), and compliance certifications (RoHS Compliant versus ROHS3 Compliant). The Molex part includes a defined operating temperature range of -40°C ~ 85°C and specifies Cat4 ratings.

Q: Are there any compatibility concerns with PCB layout or footprint?

A: Both parts feature identical through-hole mounting type, 90° right-angle orientation, and down-facing tab direction. PCB footprint compatibility is established through matching mechanical specifications. Verification of specific pad dimensions and hole sizing against manufacturer datasheets is standard engineering practice.

Q: What is the significance of the contact finish thickness specification?

A: Both parts specify 50.0µin (1.27µm) gold contact finish thickness. This specification ensures consistent electrical contact resistance, durability, and corrosion resistance across equivalent parts. Matching finish thickness confirms electrical performance equivalence.

Q: Why is the RJ11-2L-S classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Molex 0432026107 is also obsolete, reflecting industry-wide transition away from these connector designs. Current inventory availability should be confirmed with component distributors prior to procurement decisions.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tray versus unspecified) affects logistics and handling but does not alter electrical or mechanical performance. Component selection should prioritize functional equivalence and availability over packaging considerations unless specific assembly requirements mandate particular packaging formats.
