TE Connectivity 745207-2 D-Sub Plug 15-Position IDC Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745207-2 is a 15-position D-Sub plug connector with male pins, designed for IDC (Insulation Displacement Contact) and discrete wire termination. This connector belongs to the AMPLIMITE HDE-20 series and features a D-shaped shell layout (Size 2, DA/A configuration) with free-hanging, in-line mounting capability.

The 745207-2 is classified as obsolete. Locating active production alternatives is necessary to ensure continued component availability, supply chain reliability, and compliance with current regulatory standards for new designs and production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 745207-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Voltage rating (250V), contact finish composition and thickness (gold, 30.0µin), and wire gauge compatibility (22-26 AWG) must be preserved to ensure electrical performance and signal integrity.

Mechanical Parameters: Connector style (D-Sub), connector type (plug with male pins), position count (15), row configuration (2 rows), shell size and layout (Size 2, DA/A), and mounting type (free hanging, in-line) must remain unchanged to ensure physical compatibility with mating receptacles and installation requirements.

Material and Environmental Parameters: Dielectric material (thermoplastic), flammability rating (UL94 V-0), operating temperature range (-55°C ~ 105°C), and moisture sensitivity level (MSL 1) must be maintained to ensure reliability under specified environmental conditions.

Termination Compatibility: Both IDC and discrete wire termination capability must be retained to support existing assembly processes and field installation methods.

The substitute part 745207-7 satisfies all these criteria while offering the advantage of active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 745207-7 is the direct substitute for the obsolete 745207-2. Both connectors are electrically and mechanically equivalent across all functional parameters, ensuring drop-in compatibility in existing applications.

Product Status Advantage: The 745207-7 maintains active production status, providing assured long-term availability and supply chain continuity. The 745207-2, classified as obsolete, presents supply risk and may become unavailable for future procurement.

Regulatory Compliance: The 745207-7 achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The 745207-2 is RoHS non-compliant, which may restrict its use in new designs or applications subject to RoHS regulations.

Packaging Consideration: The 745207-7 is supplied in tray packaging, which is standard for production environments and supports automated assembly processes. Packaging format does not affect electrical or mechanical performance.

For new designs, production runs, and long-term applications, the 745207-7 is the appropriate selection. For legacy system maintenance where the 745207-2 is already installed, both parts are functionally interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the 745207-2 and 745207-7 physically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, shell size (Size 2, DA/A), pin configuration (15 positions, 2 rows), and mounting type (free hanging, in-line). They are direct physical substitutes.

Q: Can the 745207-7 replace the 745207-2 in existing assemblies?

A: Yes. The 745207-7 maintains all electrical specifications (250V rating, gold contact finish at 30.0µin thickness, 22-26 AWG wire gauge compatibility) and environmental ratings (UL94 V-0, -55°C ~ 105°C operating range) required for functional equivalence. No circuit or assembly modifications are necessary.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and regulatory compliance. The 745207-2 is obsolete and RoHS non-compliant. The 745207-7 is an active product with ROHS3 compliance. Both are functionally identical.

Q: Does packaging affect connector performance?

A: No. Packaging format (tray for 745207-7 versus unspecified for 745207-2) does not affect electrical performance, mechanical fit, or environmental ratings. Packaging is a logistics consideration only.

Q: Can both connectors be used with IDC and discrete wire termination?

A: Yes. Both the 745207-2 and 745207-7 support IDC (Insulation Displacement Contact) and discrete wire termination methods. Termination capability is identical between the two parts.

Q: What wire gauges are compatible with these connectors?

A: Both connectors accept wire gauges from 22 AWG to 26 AWG. This range applies to both IDC and discrete wire termination.

Q: Are there any compliance restrictions on using the 745207-2?

A: The 745207-2 is RoHS non-compliant. Applications subject to RoHS regulations or environmental compliance requirements should use the 745207-7 instead.

Q: What is the operating temperature range for these connectors?

A: Both connectors operate reliably across the temperature range of -55°C to 105°C. This specification applies to both the 745207-2 and 745207-7.
