RJ11-6L-S Equivalent & Substitute Parts

Part Overview

The RJ11-6L-S is a modular jack connector manufactured by TE Connectivity Corcom Filters, configured as a 6-position 6-contact (6p6c) unshielded right-angle through-hole connector. This component supports RJ11, RJ12, RJ14, and RJ25 applications with solder termination and features board lock and panel stops functionality.

The RJ11-6L-S is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this connector type.

Engineering Selection Recommendations

Primary Recommendation for Direct Replacement:

For applications requiring full electrical and mechanical compatibility with the RJ11-6L-S, select from the active-status 6p6c modular jack connectors:

68898-001LF, 68898-005LF, or 68898-008 (Amphenol ICC): These parts are in active production status with substantial inventory availability. All three maintain 6p6c contact configuration, 90° right-angle orientation, through-hole solder termination, and unshielded design. The 68898-001LF and 68898-005LF are RoHS Compliant; 68898-008 is RoHS non-compliant.
A-2004-1-1 or A-2004-1-2 (Assmann WSW Components): Both parts are active-status alternatives with 6p6c configuration and ROHS3 Compliance. These connectors feature polyester glass-filled housing and phosphor bronze contacts with gold finish, matching the material composition of the RJ11-6L-S.

Secondary Recommendation for Last-Time-Buy Inventory:

88400-066LF or 88400-066TLF (Amphenol ICC): These parts are designated Last Time Buy status and provide full 6p6c compatibility. Both are RoHS Compliant with board lock and panel stops features. Inventory is available but finite; these parts are suitable for applications where existing stock must be consumed.

Alternative for Reduced Contact Density Applications:

A-2004-0-1, A-2004-0-2, or A-2004-0-3 (Assmann WSW Components): These 6p4c variants are suitable only for applications supporting RJ11 and RJ14 standards. All three are active-status, ROHS3 Compliant, and feature identical mechanical mounting and termination characteristics to the RJ11-6L-S. Selection among these three variants depends on packaging requirements (bulk, tray) and contact finish thickness specifications.

Frequently Asked Questions (FAQ)

Q: Can the 6p4c variants (A-2004-0-1, A-2004-0-2, A-2004-0-3) be used as direct replacements for the RJ11-6L-S?

A: No. The RJ11-6L-S is configured as 6p6c (6 positions, 6 contacts), supporting RJ11, RJ12, RJ14, and RJ25 standards. The 6p4c variants support only RJ11 and RJ14 standards. Direct substitution is not possible if the application requires RJ12 or RJ25 compatibility. The 6p4c parts are suitable only for designs that operate exclusively within RJ11 or RJ14 specifications.

Q: What is the difference between 68898-001LF, 68898-005LF, and 68898-008?

A: All three parts are 6p6c modular jack connectors from Amphenol ICC with identical electrical and mechanical specifications. The primary differences are: 68898-001LF and 68898-005LF are RoHS Compliant; 68898-008 is RoHS non-compliant. Inventory levels differ: 68898-001LF has 5171 units, 68898-005LF has 4841 units, and 68898-008 has 775 units. Selection should be based on RoHS compliance requirements and inventory availability.

Q: What is the significance of the "Last Time Buy" status for 88400-066LF and 88400-066TLF?

A: Last Time Buy status indicates that these parts are no longer in active production and available inventory is finite. Once existing stock is depleted, these parts will not be replenished. For new designs or long-term production requirements, active-status alternatives (68898 series or A-2004 series) are recommended. Last Time Buy parts are suitable for short-term production runs or inventory replenishment of existing designs.

Q: How do packaging options differ among the substitute parts?

A: The RJ11-6L-S packaging is not specified. Substitute parts are available in multiple packaging formats: Tube (68898-001LF, 68898-005LF, 68898-008, 88400-066LF), Tray (88400-066TLF, A-2004-0-2, A-2004-0-3, A-2004-1-1, A-2004-1-2), and unspecified (A-2004-0-1). Packaging selection depends on assembly process requirements, handling procedures, and inventory management systems.

Q: Are there compliance differences between the substitute parts?

A: Yes. The Amphenol ICC 68898-001LF and 68898-005LF are RoHS Compliant; 68898-008 is RoHS non-compliant. The Amphenol ICC 88400 series (88400-066LF, 88400-066TLF) are RoHS Compliant. All Assmann WSW Components A-2004 series parts are ROHS3 Compliant. The RJ11-6L-S REACH status is REACH Unaffected. Substitute parts have varying REACH status designations. Compliance requirements should be verified against application and regulatory specifications.

Q: What contact material differences exist among the substitute parts?

A: The RJ11-6L-S uses phosphor bronze contacts. The Amphenol ICC 68898 series uses copper alloy contacts. The Amphenol ICC 88400 series uses phosphor bronze contacts. All Assmann WSW Components A-2004 series parts use phosphor bronze contacts. Contact material selection affects electrical conductivity, corrosion resistance, and mechanical durability. For applications with specific contact material requirements, the 88400 series and A-2004 series are preferred.

Q: How do operating temperature ranges compare?

A: The RJ11-6L-S operating temperature range is not specified. The Amphenol ICC 68898-001LF and 68898-005LF operate at -40°C to 70°C. The Amphenol ICC 88400 series operates at -40°C to 70°C. The Assmann WSW Components A-2004 series operates at -40°C to 85°C. For applications requiring extended high-temperature operation, the A-2004 series provides a wider operating range.

Q: What is the difference between contact finish thickness specifications?

A: Contact finish thickness varies among substitute parts: RJ11-6L-S specifies 50.0µin (1.27µm); Amphenol ICC 68898 series specifies 5.00µin (0.127µm); Amphenol ICC 88400-066LF specifies 5.00µin (0.127µm); Amphenol ICC 88400-066TLF specifies 30.0µin (0.76µm); Assmann WSW Components A-2004-0-1 specifies 15.0µin (0.38µm); A-2004-0-2 specifies 30.0µin (0.76µm); A-2004-0-3 specifies 50.0µin (1.27µm); A-2004-1-1 specifies 15.0µin (0.38µm); A-2004-1-2 specifies 30.0µin (0.76µm). Thicker finishes provide enhanced corrosion resistance and contact durability. For applications requiring maximum contact finish thickness matching the RJ11-6L-S, select A-2004-0-3.
