TE Connectivity 745492-3 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745492-3 is a 9-position D-Sub plug connector with male pins, designed for free-hanging in-line applications. This connector features IDC (Insulation Displacement Contact) and discrete wire termination capabilities, making it suitable for signal transmission in industrial and commercial environments.

The 745492-3 carries an obsolete product status. Locating equivalent and substitute parts is necessary to support legacy system maintenance, repair, and component replacement where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 745492-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector style (D-Sub)
• Connector type (Plug, Male Pins)
• Number of positions (9)
• Number of rows (2)
• Shell size and layout (1, DE, E)
• Voltage rating (250V)
• Contact material (Phosphor Bronze)
• Contact finish (Gold, Flash)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging, In-Line)
• Termination method (IDC, Discrete Wire)
• Shell material and finish (Steel, Tin Plated)
• Dielectric material (Thermoplastic, Glass Filled)

Environmental & Regulatory Parameters:

• Operating temperature range (-55°C to 105°C)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (1, Unlimited)

The substitute part 1-745492-9 maintains full equivalence across all these parameters, with the primary distinction being product status (Active versus Obsolete) and regulatory compliance (RoHS3 Compliant versus RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The 1-745492-9 serves as the direct substitute for the obsolete 745492-3. Both connectors share identical electrical and mechanical specifications within the AMPLIMITE HDE-20 series, ensuring functional interchangeability in applications requiring 9-position D-Sub plug connectors with male pins, IDC termination, and free-hanging in-line mounting.

The primary distinction between these parts is regulatory status. The 1-745492-9 carries Active product status and RoHS3 compliance, whereas the 745492-3 is Obsolete and RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the 1-745492-9 is the appropriate selection. For legacy system maintenance where original specifications must be preserved, the 745492-3 remains functionally equivalent where available inventory exists.

Both connectors maintain identical performance across the full operating temperature range (-55°C to 105°C), voltage rating (250V), and material flammability certification (UL94 V-0).

Frequently Asked Questions (FAQ)

Q: Are the 745492-3 and 1-745492-9 electrically interchangeable?
