TE Connectivity 747043-2 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 747043-2 is a 25-position D-Sub plug connector with male pins, designed for IDC ribbon cable termination in free-hanging inline applications. This connector is part of the AMPLIMITE HDF-20 series and features a steel tin-plated shell with gold-plated contacts. The part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing system support and new design implementations. Substitute parts must maintain compatibility across connector style, position count, termination method, and electrical ratings while accommodating modern product availability and compliance requirements.

Substitute Part Grouping Explanation

Substitution logic for the TE Connectivity 747043-2 is based on the following critical parameters that must align across all candidate parts:

Primary Compatibility Criteria:

Connector style (D-Sub)
Connector type (Plug, Male Pins)
Number of positions (25)
Number of rows (2)
Shell size and layout (3, DB, B)
Termination method (IDC, Ribbon Cable)
Contact type (Signal)
Flange feature (Housing/Shell with 4-40 threading or equivalent)
Material flammability rating (UL94 V-0)
Operating temperature range (-55°C ~ 105°C)
Moisture sensitivity level (1, Unlimited)

Secondary Compatibility Considerations:

Current rating (1.25A minimum for direct substitution; 1A acceptable for lower-demand applications)
Shell material and finish (Steel, Tin Plated)
Contact finish (Gold)
Features (Feed Through, Grounding Indents)

Substitute parts are grouped into two categories: direct equivalents that maintain all primary parameters, and functional alternatives that accommodate mounting type variations (panel mount versus free-hanging) while preserving electrical and mechanical compatibility.

Engineering Selection Recommendations

Direct Equivalent (Preferred for In-Line Applications):

The TE Connectivity 1658608-2 is the primary direct substitute for the 747043-2. Both connectors share identical specifications across all critical parameters: 25-position D-Sub plug configuration, free-hanging inline mounting, IDC ribbon cable termination, 1.25A current rating, and -55°C to 105°C operating temperature range. The 1658608-2 maintains the same shell material (steel, tin-plated), contact finish (gold), and flammability rating (UL94 V-0). The key distinction is product status: the 1658608-2 is active with 1885 units in stock, whereas the 747043-2 is obsolete. The 1658608-2 is RoHS compliant, addressing regulatory requirements for new designs and long-term supply chain sustainability.

Functional Alternatives (For Panel Mount Applications):

The 3M 8225-6003, 8225-6009, and 8225-8000 connectors provide functional substitution for applications where panel mounting is acceptable. These parts maintain the same 25-position D-Sub configuration, IDC ribbon cable termination, steel tin-plated shell, gold contact finish, and UL94 V-0 flammability rating. The primary difference is mounting type (panel mount versus free-hanging inline) and current rating (1A versus 1.25A). The 8225-6003 and 8225-8000 are active products with ROHS3 compliance. Selection between these alternatives depends on mechanical integration requirements and current demand specifications.

Alternative Inline Options (Amphenol ICC):

The Amphenol ICC G17K25101001EU and G17K25103101EU connectors provide inline mounting configurations equivalent to the 747043-2. Both maintain 25-position D-Sub plug configuration, free-hanging inline mounting, IDC ribbon cable termination, and UL94 V-0 flammability rating. These parts feature steel shells with gold contact finish and include feed-through and grounding indent features. Both are active products with RoHS compliance. Operating temperature and current rating specifications are not provided for these parts; confirmation of these parameters is necessary for applications with specific thermal or current requirements.

Compliance and Availability Considerations:

All substitute parts listed are active products with current manufacturing status, addressing the obsolescence of the 747043-2. RoHS compliance is achieved across all active substitutes, supporting regulatory requirements in EU and equivalent markets. Moisture sensitivity level (MSL 1, Unlimited) is consistent across all parts, eliminating storage and handling constraints. ECCN classification (EAR99) and HTSUS codes are uniform, simplifying export and procurement documentation.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1658608-2 be used as a direct replacement for the 747043-2 in existing designs?

A: Yes. The 1658608-2 is electrically and mechanically equivalent to the 747043-2 across all specified parameters. Both are 25-position D-Sub plugs with male pins, free-hanging inline mounting, IDC ribbon cable termination, 1.25A current rating, and -55°C to 105°C operating temperature. The 1658608-2 is an active product with RoHS compliance, making it suitable for both legacy system support and new designs.

Q: What is the primary difference between the 747043-2 and the 3M 8225 series connectors?

A: The main difference is mounting type. The 747043-2 is free-hanging inline, while the 8225-6003, 8225-6009, and 8225-8000 are panel mount connectors. Additionally, the 8225 series has a 1A current rating compared to the 747043-2's 1.25A rating. The 8225 series is suitable for applications where panel mounting is required and current demand does not exceed 1A.

Q: Are the Amphenol ICC G17K25101001EU and G17K25103101EU suitable replacements for inline applications?

A: The Amphenol ICC G17K25101001EU and G17K25103101EU maintain the same inline mounting configuration as the 747043-2 and share the same 25-position D-Sub plug design with IDC ribbon cable termination. However, operating temperature and current rating specifications are not provided for these parts. Confirmation of these parameters against application requirements is necessary before selection.

Q: Does the 1658608-2 have the same flange feature as the 747043-2?

A: The 747043-2 specifies a Housing/Shell flange feature with 4-40 threading. The 1658608-2 does not specify flange feature details in the provided data. Mechanical compatibility should be confirmed through detailed dimensional drawings or manufacturer documentation before implementation in applications requiring specific flange configurations.

Q: What packaging options are available for substitute parts?

A: The TE Connectivity 1658608-2 is supplied in bulk packaging. The 3M 8225-6003 is supplied in tray packaging, while 8225-6009 and 8225-8000 are supplied in bulk. The Amphenol ICC G17K25101001EU is supplied in box packaging, and G17K25103101EU packaging is not specified. Packaging selection should align with procurement volume and inventory management requirements.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are RoHS compliant. The 1658608-2 is RoHS compliant. The 3M 8225-6003, 8225-6009, and 8225-8000 are ROHS3 compliant. The Amphenol ICC G17K25101001EU and G17K25103101EU are RoHS compliant. The original 747043-2 is RoHS non-compliant, making substitution necessary for new designs subject to RoHS regulations.

Q: What is the contact material difference between the 747043-2 and the 3M 8225 series?

A: The 747043-2 uses phosphor bronze contacts, while the 3M 8225 series uses copper alloy contacts. Both materials are suitable for signal-level applications with gold plating. Contact material selection does not affect electrical compatibility for standard D-Sub signal applications.

Q: Can the 747043-2 be used interchangeably with panel mount alternatives in new designs?

A: No. The 747043-2 is designed for free-hanging inline mounting. Panel mount alternatives such as the 3M 8225 series require different mechanical integration and cannot be used interchangeably without redesign of the mounting structure. Mounting type selection must align with the mechanical design of the application.

Q: What is the inventory status for substitute parts?

A: The TE Connectivity 1658608-2 has 1885 units in stock. The 3M 8225-6003 has 879 units, 8225-6009 has 1337 units, and 8225-8000 has 2274 units. The Amphenol ICC G17K25101001EU has 753 units and G17K25103101EU has 1035 units. Inventory levels support immediate procurement for most applications.
