TE Connectivity 103945-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103945-9 is a 10-position rectangular plug connector from the AMPMODU MTE series, designed for discrete wire termination using insulation displacement contact (IDC) technology. The connector accommodates 22-26 AWG wire gauges and features gold-plated male pins with a 0.100" (2.54mm) pitch in a single-row configuration. This part is classified as Active product status and is currently in stock with 927 pieces available. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across alternative part numbers, particularly when compliance certifications or packaging variations differ from the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 103945-9 is determined by strict equivalence across the following critical parameters:

• Connector Type and Position Count: Plug configuration with 10 positions
• Pitch and Row Configuration: 0.100" (2.54mm) pitch in single-row layout
• Contact Specifications: Male pin contacts with gold finish at 15.0µin (0.38µm) thickness
• Cable Termination Method: IDC technology for 22-26 AWG discrete wire
• Mounting and Fastening: Free hanging in-line mounting with latch holder fastening
• Physical Characteristics: Black color, tube packaging, AMPMODU MTE series

The substitute part 5-103945-9 maintains complete electrical and mechanical equivalence to the main part number across all specified parameters. The primary distinction between these part numbers relates to regulatory compliance status and inventory availability rather than functional or dimensional characteristics.

Parameter Comparison

Engineering Selection Recommendations

Part 103945-9 is suitable for applications where RoHS non-compliant components are acceptable or required by design specification. This part number maintains Active product status with established supply availability.

Part 5-103945-9 is the preferred selection for applications requiring RoHS compliance certification. This variant is functionally and mechanically identical to 103945-9 while meeting RoHS regulatory requirements. The substitute part offers higher inventory availability (2032 pieces versus 927 pieces) and maintains all electrical and mechanical specifications. REACH status differs between the two part numbers, with 5-103945-9 listed as Vendor Undefined.

Selection between these part numbers should be based on regulatory compliance requirements applicable to the end application and system design constraints.
