TE Connectivity 746611-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 746611-3 is a 16-position ribbon cable DIP header connector with IDC termination for through-hole mounting applications. This connector features a vertical orientation with dual-row configuration and gold-plated contacts suitable for 28 AWG stranded or 26-30 AWG solid wire gauges.

The 746611-3 carries an obsolete product status, necessitating identification of active equivalent components to maintain design continuity and ensure long-term supply chain reliability. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing circuit board designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 746611-3 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 746611-6 maintains identical specifications in the following key areas:

Position count, connector type, cable pitch, board-side pitch, row configuration, row spacing, mounting methodology, IDC termination type, wire gauge compatibility, contact finish material, contact finish thickness, color, and series designation all remain unchanged between the main part and substitute.

The primary distinction between these components is product status and packaging configuration. The 746611-3 is classified as obsolete, while the 746611-6 maintains active product status with tray packaging. Both components share the same base product number (746611) and are manufactured by TE Connectivity AMP Connectors.

Parameter Comparison

Engineering Selection Recommendations

The 746611-6 serves as the direct functional equivalent to the obsolete 746611-3. Both components are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch dimensions, termination method, and contact characteristics.

The 746611-6 is the recommended selection for new designs and component replacement applications. This part maintains active product status, ensuring continued availability and supply chain stability. The 746611-6 achieves ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the 746611-3 does not comply with RoHS standards.

Both components share identical moisture sensitivity levels and export classification codes. The packaging difference (tray for 746611-6 versus unspecified for 746611-3) does not affect functional performance or board-level compatibility.

Frequently Asked Questions (FAQ)
