TE Connectivity 103944-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103944-5 is a 6-position rectangular plug connector designed for IDC (Insulation Displacement Contact) termination on ribbon cable. This connector operates as a male pin plug with a 0.100" pitch configuration and supports wire gauges from 22 to 26 AWG. The connector features a closed-end design with tin-lead contact finish and is part of the AMPMODU MTE series.

The 103944-5 maintains active product status and is currently in stock. Identifying equivalent and substitute parts is necessary to support procurement flexibility, manage supply chain continuity, and accommodate varying compliance requirements across different manufacturing environments and end-use applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 103944-5 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Plug)
• Number of positions (6)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)
• Contact type (Male Pin)
• Cable termination method (IDC)
• Wire gauge range (22-26 AWG)
• Wire type (Ribbon Cable)
• Mounting type (Free Hanging In-Line)
• Closed-end feature
• Contact finish thickness (100.0µin / 2.54µm)
• Color (Black)
• Series designation (AMPMODU MTE)
• Moisture sensitivity level (1)

The substitute part 5-103944-5 maintains complete equivalence across all mandatory parameters. The primary distinction between the main part and its substitute relates to contact finish composition and RoHS compliance status, which do not affect mechanical or electrical interchangeability within the specified parameter set.

Engineering Selection Recommendations

103944-5 (Tin-Lead Contact Finish)

The 103944-5 is suitable for applications where RoHS compliance is not a requirement. This part maintains active product status and is available in inventory. The tin-lead contact finish provides established performance characteristics in legacy systems and applications predating RoHS3 mandates.

5-103944-5 (Tin Contact Finish)

The 5-103944-5 is the appropriate selection for applications requiring ROHS3 compliance. This substitute maintains identical mechanical and electrical specifications while incorporating a tin contact finish that satisfies current regulatory requirements. The part is active and maintains higher inventory availability.

Both parts are functionally interchangeable within the specified parameter set. Selection between them depends solely on compliance requirements and regulatory environment of the end application.

Frequently Asked Questions (FAQ)

Q: Are the 103944-5 and 5-103944-5 mechanically interchangeable?

A: Yes. Both connectors maintain identical pitch (0.100"), position count (6), row configuration (1), mounting type (free hanging in-line), and closed-end design. They accept the same ribbon cable gauge range (22-26 AWG) and use identical IDC termination methodology.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 103944-5 uses tin-lead contact finish, while the 5-103944-5 uses tin contact finish. Both maintain the same 100.0µin (2.54µm) thickness specification. The contact finish material does not affect mechanical fit or electrical performance within the specified parameter set.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory compliance requirements. For applications requiring ROHS3 compliance, the 5-103944-5 is the appropriate choice. For legacy systems or applications without RoHS requirements, either part is acceptable based on availability and procurement considerations.

Q: Are there packaging differences between these parts?

A: The 103944-5 packaging is not specified in the provided data. The 5-103944-5 is supplied in tube packaging. Confirm packaging requirements with procurement specifications before final selection.

Q: Can these connectors be used with non-ribbon cable?

A: No. Both connectors are specified for ribbon cable termination using IDC methodology. Wire type is restricted to ribbon cable with gauge range 22-26 AWG.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
