TE Connectivity 747548-2 D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity 747548-2 is a 25-position D-Sub receptacle connector with female sockets, designed for IDC (Insulation Displacement Contact) and discrete wire termination. This connector is part of the AMPLIMITE HDE-20 series and features a shielded, free-hanging in-line mounting configuration with tin-plated steel shell and gold-plated contacts.

The 747548-2 carries an obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or field replacement requirements for legacy systems utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 747548-2 are identified based on strict electrical and mechanical parameter equivalence within the D-Sub receptacle connector category. The substitution logic is based on the following critical parameters:

Connector Configuration Parameters:

• Connector style (D-Sub)
• Connector type (Receptacle, Female Sockets)
• Number of positions (25)
• Number of rows (2)
• Shell size and layout (3 / DB, B)

Electrical and Environmental Parameters:

• Termination method (IDC, Discrete Wire)
• Voltage rating (250V)
• Operating temperature range (-55°C ~ 105°C)
• Wire gauge compatibility (22-26 AWG)
• Contact material (Phosphor Bronze)

Physical and Material Parameters:

• Mounting type (Free Hanging / In-Line)
• Shell material and finish (Steel, Tin Plated)
• Contact finish (Gold)
• Contact finish thickness (30.0µin / 0.76µm)
• Flange feature (Housing/Shell, Unthreaded)
• Dielectric material (Thermoplastic)
• Flammability rating (UL94 V-0)

Parts meeting all these parameters are classified as direct substitutes and maintain full functional and mechanical compatibility with the original 747548-2 specification.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 747548-8 is the direct substitute for the obsolete 747548-2. Both connectors share identical electrical, mechanical, and environmental specifications within the AMPLIMITE HDE-20 series.

Product Status Consideration: The 747548-2 is classified as obsolete, while the 747548-8 maintains active product status. Selection of the 747548-8 ensures continued availability and supply chain support for new production builds and field replacements.
