TE Connectivity 1-111446-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-111446-3 is a 64-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for ribbon cable applications with 26-28 AWG wire gauge. This connector features gold-plated contacts, a 0.100" pitch configuration with 2-row layout, and free-hanging in-line mounting. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-111446-3 is determined by strict equivalence across the following critical parameters: 64-position count, 0.100" pitch, 2-row configuration with 0.100" row spacing, IDC cable termination method, 26-28 AWG wire gauge compatibility, gold contact finish at 30.0µin thickness, and feed-through feature capability. Substitute parts must maintain identical electrical performance through matching contact specifications and mechanical compatibility through matching connector geometry and mounting characteristics.

The identified substitutes are grouped as follows:

Direct Manufacturer Equivalent: TE Connectivity 2-111446-6 maintains complete parameter alignment with the original part while offering active product status and improved compliance certifications.

Cross-Manufacturer Alternative: 3M 4664-6001 provides functional equivalence across all critical electrical and mechanical parameters while accommodating both discrete and ribbon cable wire types.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 2-111446-6 is the primary substitute for the obsolete 1-111446-3. This part is manufactured by the original equipment supplier and maintains complete electrical and mechanical parameter equivalence. The 2-111446-6 carries active product status, ROHS3 compliance certification, and REACH unaffected status, providing superior regulatory alignment compared to the original part. The transition from the 1-111446-3 to 2-111446-6 requires no design modifications and presents no compatibility concerns.

3M 4664-6001 serves as a secondary cross-manufacturer alternative when TE Connectivity supply is constrained. This part meets all critical electrical and mechanical specifications and carries active product status with ROHS3 compliance. The 4664-6001 accommodates both discrete and ribbon cable configurations, providing additional application flexibility. The gray connector color differs from the black original specification but does not affect electrical performance or mechanical fit. Cross-manufacturer substitution requires verification of connector mating interface compatibility with existing socket receptacles.

Frequently Asked Questions (FAQ)

Q: Can the 2-111446-6 be used as a direct replacement for the 1-111446-3 without design changes?

A: Yes. The 2-111446-6 maintains identical specifications across all critical parameters: 64-position count, 0.100" pitch, 2-row configuration, IDC termination, 26-28 AWG wire gauge, gold contact finish at 30.0µin thickness, and free-hanging in-line mounting. No design modifications are required.

Q: What is the primary difference between the 1-111446-3 and 2-111446-6?

A: The 2-111446-6 is the active production equivalent with improved regulatory compliance. The original 1-111446-3 is obsolete and RoHS non-compliant, while the 2-111446-6 carries ROHS3 compliance and REACH unaffected status. Electrical and mechanical specifications are identical.

Q: Can the 3M 4664-6001 be substituted for the TE Connectivity parts?

A: The 4664-6001 meets all critical electrical and mechanical specifications and is functionally equivalent. However, cross-manufacturer substitution requires verification of mating interface compatibility with existing socket receptacles. The connector color is gray rather than black.

Q: What wire types are compatible with each substitute?

A: The 1-111446-3 and 2-111446-6 are specified for ribbon cable with 26-28 AWG wire gauge. The 3M 4664-6001 accommodates both discrete and ribbon cable configurations with 26-28 AWG wire gauge in stranded or solid conductor types.

Q: Are there packaging differences between the substitutes?

A: Yes. The 1-111446-3 packaging is not specified. The 2-111446-6 is supplied in tray packaging. The 4664-6001 is supplied in bulk packaging. Packaging differences do not affect connector performance or compatibility.

Q: Do all substitutes maintain the same contact finish specifications?

A: Yes. All three parts feature gold contact finish at 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and corrosion resistance.

Q: What is the MSL rating for these connectors?

A: All three parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations for storage or handling.
