TE Connectivity 103948-4 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103948-4 is a 5-position rectangular plug connector designed for IDC (Insulation Displacement Contact) termination on ribbon cable. This connector operates within the AMPMODU MTE series and features gold-plated male pins rated for 26-30 AWG wire gauges. The part is currently active in production with 1108 units in stock.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory depletion occurs, or when alternative sourcing is required to maintain supply chain continuity. The substitute identified for this connector maintains identical electrical and mechanical specifications, ensuring direct functional equivalence.

• Number of positions (5)
• Contact type (Male Pin)
• Contact finish (Gold) and finish thickness (15.0µin)
• Wire gauge compatibility (26-30 AWG)

Mechanical Parameters:

• Pitch spacing (0.100" / 2.54mm)
• Number of rows (1)
• Mounting configuration (Free Hanging, In-Line)
• Cable termination method (IDC)
• Wire type (Ribbon Cable)
• Physical features (Closed End)
• Color (Black)

Series Compatibility:

• AMPMODU MTE series designation

The substitute part 5-103948-4 meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent. This part shares the identical base product number (103948) with a variant designation prefix, indicating manufacturer-level equivalence within the same product family.

Engineering Selection Recommendations

Primary Selection: 103948-4

The TE Connectivity 103948-4 is the recommended primary choice for new designs and current production applications. This part maintains active product status with confirmed inventory availability (1108 units in stock). The connector meets all specified electrical and mechanical requirements for 5-position IDC ribbon cable termination at 26-30 AWG wire gauges.

Alternative Selection: 5-103948-4

The substitute part 5-103948-4 provides functional equivalence across all electrical and mechanical parameters. This part is suitable for applications requiring RoHS compliance certification, as it carries explicit RoHS Compliant status and REACH Unaffected designation. However, this part is discontinued at DiGi Electronics, limiting long-term availability. Current inventory stands at 724 units.

Compliance Considerations:

Applications subject to RoHS or REACH regulatory requirements should specify 5-103948-4 to ensure documented compliance. The primary part (103948-4) carries "Not applicable" RoHS status and "Vendor Undefined" REACH status, which may present compliance documentation challenges in regulated environments.

Inventory and Supply Chain:

The primary part 103948-4 offers superior supply chain continuity with higher current inventory levels and active production status. The substitute should be reserved for applications where compliance certifications are mandatory or when primary part availability becomes constrained.

Frequently Asked Questions (FAQ)

Q: Can 5-103948-4 be used as a direct replacement for 103948-4 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The 5-103948-4 functions as a direct substitute without requiring design modifications, PCB changes, or assembly procedure adjustments.

Q: What is the difference between 103948-4 and 5-103948-4?

A: The parts share identical electrical and mechanical specifications. The primary differences are product status (103948-4 is active; 5-103948-4 is discontinued at DiGi Electronics) and compliance certifications (5-103948-4 carries explicit RoHS Compliant and REACH Unaffected designations, while 103948-4 status is undefined or not applicable).

Q: Which part should be specified for new product designs?

A: Specify 103948-4 for new designs unless RoHS or REACH compliance documentation is required. If compliance certifications are mandatory, specify 5-103948-4 and verify long-term availability with your supplier.

Q: Are there packaging differences between these parts?

A: The primary part 103948-4 is packaged in tubes. Packaging information for 5-103948-4 is not specified in available documentation.

Q: Can these connectors be used with wire gauges outside the 26-30 AWG range?

A: No. Both parts are rated exclusively for 26-30 AWG ribbon cable. IDC termination requires wire gauges within this specified range for proper contact engagement and electrical performance.

Q: What is the pitch spacing for these connectors?

A: Both parts operate at 0.100" (2.54mm) pitch spacing. This standard spacing is compatible with AMPMODU MTE series receptacles and mating connectors designed for this pitch.

Q: Are these connectors suitable for ribbon cable applications?

A: Yes. Both parts are specifically designed for IDC termination on ribbon cable. The closed-end design and male pin configuration are optimized for ribbon cable connector systems.

Q: What contact finish is used on these connectors?

A: Both parts feature gold-plated contacts with 15.0µin (0.38µm) finish thickness, providing corrosion resistance and reliable electrical contact performance.
