TE Connectivity 745497-1 D-Sub 37-Position Receptacle Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745497-1 is a 37-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 free-hanging, in-line mounting configuration with a shell size 4 (DC, C) layout.

The 745497-1 carries an obsolete product status. Locating equivalent and substitute components is necessary to support legacy system maintenance, repair, and continued field deployment where this connector type remains in active use.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 745497-1 is determined by strict equivalence across the following critical parameters:

Connector Architecture: Connector style (D-Sub), connector type (receptacle with female sockets), number of positions (37), number of rows (2), and shell size/layout (4, DC, C) must be identical.

Termination Compatibility: Termination method (IDC, Discrete Wire) must match to ensure compatibility with existing cable assemblies and installation tooling.

Mounting Configuration: Mounting type (free hanging, in-line) must be identical to fit within the mechanical envelope of the application.

Electrical and Environmental Ratings: Voltage rating (250V), operating temperature range (-55°C ~ 105°C), wire gauge support (26-30 AWG), and contact material (phosphor bronze) must be equivalent.

Material and Finish Specifications: Shell material and finish (steel, tin plated), contact finish (gold), contact finish thickness (30.0µin), and dielectric material (thermoplastic, glass filled) must match.

Compliance and Safety: Material flammability rating (UL94 V-0) and moisture sensitivity level (MSL 1) must be maintained.

The substitute part 1-745497-6 meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 1-745497-6 is a direct functional equivalent to the 745497-1 across all electrical, mechanical, and environmental parameters. Both connectors share identical specifications for connector architecture, termination method, mounting configuration, electrical ratings, material composition, and safety certifications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 745497-1 is obsolete and carries RoHS non-compliant status with vendor-undefined REACH status. The 1-745497-6 is an active product with RoHS compliance and REACH unaffected status, making it suitable for new designs and applications subject to environmental regulations.

For applications requiring the 745497-1, the 1-745497-6 provides a direct replacement with improved regulatory standing and ongoing manufacturer support. Both parts are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE HDE-20 series and maintain identical form, fit, and function.
