TE Connectivity 745497-2 D-Sub 37-Position Receptacle Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 745497-2 is a 37-position D-Sub receptacle connector with female sockets, designed for IDC (Insulation Displacement Contact) and discrete wire termination. This connector belongs to the AMPLIMITE HDE-20 series and features a free-hanging, in-line mounting configuration with shell size 4 (DC, C) layout.

The 745497-2 is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, repair, and field replacement requirements where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 745497-2 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Connector Architecture: D-Sub receptacle configuration with 37 positions arranged in 2 rows, shell size 4 (DC, C) layout, and free-hanging in-line mounting.

Electrical Characteristics: 250V voltage rating, gold-plated contacts with 30.0µin thickness, phosphor bronze contact material, and support for 22-26 AWG wire gauges.

Termination Compatibility: IDC and discrete wire termination capability.

Environmental & Material Specifications: Steel tin-plated shell, thermoplastic glass-filled dielectric, UL94 V-0 flammability rating, and -55°C to 105°C operating temperature range.

Series Designation: AMPLIMITE HDE-20 series membership.

The substitute part 1-745497-5 meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 1-745497-5 is the direct equivalent substitute for the obsolete 745497-2. Both components are manufactured by TE Connectivity AMP Connectors and share identical electrical, mechanical, and environmental specifications across all critical parameters.

Product Status Advantage: The 1-745497-5 maintains active product status, ensuring continued availability and supply chain support. The 745497-2 is obsolete and subject to inventory depletion.

Compliance Improvement: The 1-745497-5 is ROHS3 compliant, whereas the 745497-2 is RoHS non-compliant. This represents an advancement in environmental and regulatory compliance for new installations or system upgrades.

Functional Interchangeability: All electrical ratings, termination methods, contact specifications, and environmental operating parameters are identical. The 1-745497-5 is a direct pin-for-pin and functionally equivalent replacement.

Packaging Consideration: The 1-745497-5 is supplied in bulk packaging, whereas the 745497-2 packaging specification is not defined. Bulk packaging is standard for active production components and supports efficient inventory management.

Frequently Asked Questions (FAQ)

Q: Can the 1-745497-5 be used as a direct replacement for the 745497-2 in existing applications?

A: Yes. The 1-745497-5 is a direct functional equivalent. All electrical ratings (250V), contact specifications (gold-plated phosphor bronze, 30.0µin thickness), termination methods (IDC and discrete wire), and environmental operating parameters (-55°C to 105°C) are identical. The connector maintains the same D-Sub 37-position receptacle configuration, shell size 4 layout, and free-hanging in-line mounting.

Q: What is the difference between the 745497-2 and 1-745497-5?

A: The primary differences are product status and regulatory compliance. The 745497-2 is obsolete and RoHS non-compliant. The 1-745497-5 is an active product with ROHS3 compliance. All functional and electrical specifications are identical.

Q: Are there any compatibility issues when substituting the 1-745497-5 for the 745497-2?
