RJ11-6L-B Equivalent & Substitute Parts

Part Overview

The RJ11-6L-B is a modular jack connector manufactured by TE Connectivity Corcom Filters, configured as a 6-position 6-contact (6p6c) right-angle unshielded connector with through-hole solder termination. This connector supports RJ11, RJ12, RJ14, and RJ25 applications and includes board lock and filter features. The product is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design and procurement requirements.

Substitute Part Grouping Explanation

Substitution of the RJ11-6L-B is determined by strict equivalence across the following critical parameters: connector type (jack), number of positions and contacts (6p6c), orientation (90° right angle), mounting type (through hole), termination method (solder), shielding configuration (unshielded), tab direction (down), number of ports (1), and number of rows (1).

Substitute parts are grouped into two categories based on contact position configuration:

Category 1: Full 6p6c Equivalents – Parts maintaining identical 6-position 6-contact configuration compatible with RJ11, RJ12, RJ14, and RJ25 standards.

Category 2: Reduced 6p4c Variants – Parts with 6-position 4-contact configuration compatible with RJ11 and RJ14 standards only. These parts are functionally compatible for applications not requiring RJ12 or RJ25 support.

All substitute parts maintain through-hole solder termination, right-angle orientation, unshielded configuration, and downward tab direction. Variations in contact material (phosphor bronze versus copper alloy), contact finish thickness, housing material composition, and product status are secondary parameters that do not prevent functional substitution within the specified connector category.

Engineering Selection Recommendations

Primary Substitutes (Full 6p6c Equivalents with Active Status):

The Assmann WSW Components A-2004-1-1 and A-2004-1-2 are the recommended primary substitutes for the RJ11-6L-B. Both parts maintain identical 6p6c contact configuration, through-hole solder termination, right-angle orientation, and unshielded design. Both are classified as active products with ROHS3 compliance and REACH unaffected status. A-2004-1-1 features 15.0µin contact finish thickness, while A-2004-1-2 provides 30.0µin thickness. Both support operating temperatures from -40°C to 85°C, exceeding the original part's environmental range.

Secondary Substitutes (Full 6p6c Equivalents with Last Time Buy Status):

The Amphenol ICC (FCI) 88400-066LF and 88400-066TLF maintain full 6p6c equivalence with phosphor bronze contacts matching the original part's contact material. Both are classified as Last Time Buy status with RoHS compliance and REACH affected designation. The 88400-066LF is packaged in tube format with 5.00µin contact finish thickness. The 88400-066TLF is packaged in tray format with 30.0µin contact finish thickness and GXT™ gold finish. Both support -40°C to 70°C operating temperature range.

Tertiary Substitutes (Full 6p6c Equivalents with Active Status):

The Amphenol ICC (FCI) 68898-001LF and 68898-005LF provide full 6p6c equivalence with active product status. Both feature copper alloy contacts with 5.00µin gold finish thickness and support -40°C to 70°C operating temperature. The 68898-001LF is RoHS compliant with REACH affected status. The 68898-005LF is RoHS compliant with REACH unaffected status. The 68898-008 maintains 6p6c configuration with active status but is RoHS non-compliant.

Reduced-Contact Alternatives (6p4c Configuration):

The Assmann WSW Components A-2004-0-1, A-2004-0-2, and A-2004-0-3 provide 6p4c configuration compatible with RJ11 and RJ14 applications only. These parts are suitable for applications not requiring RJ12 or RJ25 support. All three are active products with ROHS3 compliance and REACH unaffected status, supporting -40°C to 85°C operating temperature. Contact finish thickness varies: A-2004-0-1 provides 15.0µin, A-2004-0-2 provides 30.0µin, and A-2004-0-3 provides 50.0µin thickness.

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-B?

A: The 6p4c variants are functionally compatible only for applications using RJ11 or RJ14 standards. They are not suitable for designs requiring RJ12 or RJ25 support due to reduced contact count. Verify application requirements before substitution.

Q: What is the difference between the Amphenol ICC (FCI) 88400-066LF and 88400-066TLF?

A: Both parts are electrically and mechanically equivalent 6p6c connectors with identical contact material (phosphor bronze) and finish (gold). The primary differences are packaging format (88400-066LF in tube, 88400-066TLF in tray) and contact finish thickness (5.00µin versus 30.0µin). The 88400-066TLF includes GXT™ gold finish designation.

Q: Are the Amphenol ICC (FCI) 68898 series parts suitable replacements despite copper alloy contacts versus phosphor bronze?

A: The 68898-001LF and 68898-005LF maintain full 6p6c equivalence with identical connector geometry, orientation, and termination. Contact material variation (copper alloy versus phosphor bronze) does not prevent functional substitution within the modular connector category. Both parts are active with established supply availability.

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

A: Last Time Buy status indicates these parts remain available for procurement but will be discontinued. Amphenol ICC (FCI) has established a final purchase window. For new designs or long-term production requirements, the active status Assmann WSW Components A-2004-1-1 or A-2004-1-2 are preferred to ensure sustained supply.

Q: How do operating temperature ranges compare across substitute options?

A: The RJ11-6L-B does not specify an operating temperature range. The Assmann WSW Components A-2004 series supports -40°C to 85°C. The Amphenol ICC (FCI) 88400 and 68898 series support -40°C to 70°C. For applications requiring extended temperature performance, the A-2004 series provides superior thermal range.

Q: What packaging options are available for the recommended substitutes?

A: The Assmann WSW Components A-2004-1-1 and A-2004-1-2 are supplied in tray packaging. The Amphenol ICC (FCI) 88400-066LF is supplied in tube packaging, while 88400-066TLF is supplied in tray packaging. The 68898 series is supplied in tube packaging. Packaging selection should align with production assembly requirements and inventory management protocols.

Q: Are all substitute parts RoHS compliant?

A: The Assmann WSW Components A-2004 series is ROHS3 compliant. The Amphenol ICC (FCI) 88400 series is RoHS compliant. The 68898-001LF and 68898-005LF are RoHS compliant, while 68898-008 is RoHS non-compliant. For applications requiring RoHS compliance, exclude 68898-008 from consideration.

Q: What is the difference between REACH affected and REACH unaffected status?

A: REACH affected status indicates the part contains substances of very high concern (SVHC) listed under EU REACH regulations. REACH unaffected status indicates the part does not contain listed SVHC substances. For applications subject to REACH compliance requirements, select parts with REACH unaffected designation.
