TE Connectivity 747958-1 D-Sub Connector Housing: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 747958-1 is a D-Sub connector housing plug designed for 37-position male contact applications. This component functions as the outer shell assembly for D-Sub connectors in the AMPLIMITE HDP-20 series, featuring a shielded design with grounding indents and backshell integration. The part is classified as obsolete, making identification of active equivalent components essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without design modification.

Substitute Part Grouping Explanation

Substitution eligibility for the 747958-1 connector housing is determined by strict equivalence across all mechanical and electrical parameters. The substitute part 5747958-1 qualifies as a direct equivalent based on the following criteria:

Critical Matching Parameters:

• Connector style, type, and position count (D-Sub, plug for male contacts, 37 positions)
• Shell size and connector layout (Size 4, DC/C configuration)
• Mounting configuration and flange specifications (Free hanging, cable-side 4-40 flange)
• Shell material and finish composition (Steel, tin plated)
• Dielectric material properties (Polyamide, nylon, glass filled)
• Integrated features (Backshell, grounding indents, shielded design)
• Physical color specification (Black)
• Series designation (AMPLIMITE HDP-20)

The substitute part maintains complete functional and dimensional compatibility with the original component. Differences in product status and compliance certifications do not affect mechanical or electrical interchangeability.

Engineering Selection Recommendations

The 5747958-1 serves as the direct active equivalent for the obsolete 747958-1 connector housing. Selection of the substitute part is based on the following engineering factors:

Product Status Consideration: The original 747958-1 is classified as obsolete, while the 5747958-1 maintains active product status. This distinction ensures continued availability and manufacturer support for the substitute component.

Compliance Advantage: The substitute part 5747958-1 carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. For applications subject to regulatory requirements or customer specifications mandating RoHS compliance, the substitute part satisfies these requirements without functional compromise.

Specification Documentation: The substitute part includes documented shell finish thickness specification (200µin / 5.08µm), providing enhanced traceability and quality assurance compared to the original part specification.

Mechanical and Electrical Equivalence: All critical parameters determining connector functionality, mating compatibility, and electrical performance remain identical between the original and substitute parts. Direct substitution is supported without design modification or system re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the 5747958-1 be used as a direct replacement for the 747958-1 in existing assemblies?

A: Yes. The 5747958-1 maintains complete mechanical and electrical equivalence with the 747958-1 across all specified parameters. The connector style, position count, shell size, mounting configuration, material composition, and integrated features are identical. Direct substitution is supported without modification to mating components or system design.

Q: What is the significance of the product status difference between the two parts?

A: The 747958-1 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 5747958-1 is active, ensuring ongoing production, consistent supply, and manufacturer technical support. For new designs or ongoing procurement, the active substitute part is the appropriate selection.

Q: Does the RoHS3 compliance of the 5747958-1 affect compatibility with the original 747958-1 design?

A: No. RoHS compliance status reflects material composition and manufacturing process standards, not connector functionality or mating characteristics. The substitute part maintains identical electrical and mechanical performance. For applications requiring RoHS compliance, the 5747958-1 satisfies regulatory requirements while preserving full compatibility with existing connector systems.

Q: Are there packaging differences between the 747958-1 and 5747958-1?

A: The 747958-1 packaging is not specified in the available documentation. The 5747958-1 is supplied in bulk packaging. Packaging format does not affect connector performance or interchangeability. Component selection should be based on mechanical and electrical specifications rather than packaging configuration.

Q: What does the shell finish thickness specification of 200µin (5.08µm) on the 5747958-1 indicate?

A: This specification documents the thickness of the tin plating applied to the steel shell. The original 747958-1 does not include this specification in available documentation. The documented thickness on the substitute part provides enhanced quality traceability and ensures consistent corrosion resistance and electrical conductivity across production batches.

Q: Are contacts included with either the 747958-1 or 5747958-1?

A: No. Both parts are connector housings only. The specification note "Contacts Not Included" applies to both the original and substitute parts. Contacts must be sourced separately and inserted into the housing assembly during connector assembly operations.

Q: Can the 5747958-1 be used in applications originally designed for the 747958-1?

A: Yes. The substitute part is fully compatible with all applications designed for the 747958-1. All mechanical interfaces, electrical characteristics, and functional specifications are maintained. The substitute part can be integrated into existing designs without modification.
