TE Connectivity AMP Connectors 745174-4 D-Sub Backshell Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 745174-4 is a 37-position two-piece backshell connector with 180° cable exit and shielding, designed for D-Sub applications. This component functions as an accessory assembly for D-Sub connectors in the AMPLIMITE series, providing mechanical strain relief and electromagnetic shielding for circular cable configurations.

The 745174-4 carries an obsolete product status, necessitating identification of functionally equivalent alternatives for ongoing procurement and system maintenance. Active substitute components are available that maintain full electrical and mechanical compatibility while offering current manufacturing support and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 745174-4 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must maintain identical specifications for connector position count, shell size compatibility, cable exit geometry, shielding configuration, material composition, and hardware specifications.

The following parameters establish substitution validity:

• Number of Positions: 37 (exact match required)
• Compatible Shell Size: C (exact match required)
• Compatible D-Sub Size: 37pos and HD62pos (exact match required)
• Cable Exit: 180° (exact match required)
• Shielding: Shielded (exact match required)
• Cable Type: Round (exact match required)
• Material: Metal, Zinc Alloy (exact match required)
• Plating: Nickel over Copper (exact match required)
• Hardware: Mating Screws 4-40 (exact match required)

The substitute part 5745174-4 satisfies all substitution criteria through complete parameter alignment with the main part specification.

Engineering Selection Recommendations

The substitute part 5745174-4 provides direct functional replacement for the obsolete 745174-4 across all electrical and mechanical parameters. Selection of the substitute component is supported by the following engineering considerations:

Product Status: The 745174-4 is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The 5745174-4 maintains active product status with current manufacturing support and established supply chain availability.

Compliance Certifications: The 5745174-4 achieves RoHS compliance, whereas the 745174-4 is non-compliant. For applications subject to RoHS regulatory requirements, the substitute part satisfies mandatory compliance obligations. The 5745174-4 is designated as REACH Affected, providing defined regulatory status compared to the vendor-undefined status of the main part.

Packaging Configuration: The 5745174-4 is supplied in bulk packaging, whereas the 745174-4 packaging specification is not defined. Bulk packaging supports efficient inventory management and procurement workflows for production environments.

Hardware Assembly: Both components include identical mating screw specifications (4-40) and strain relief hardware, ensuring mechanical compatibility with existing D-Sub connector assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 5745174-4 substitute directly for the 745174-4 in existing D-Sub connector assemblies?

A: Yes. The 5745174-4 maintains complete electrical and mechanical equivalence with the 745174-4 across all critical parameters, including position count, shell size, cable exit angle, shielding configuration, material composition, and hardware specifications. Direct substitution is supported without modification to connector assembly or cable routing.

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

A: The 745174-4 is obsolete, indicating TE Connectivity has discontinued manufacturing and support. The 5745174-4 is active, meaning current production, established supply chain availability, and ongoing technical support are available. For new designs or long-term procurement planning, the active substitute part is the appropriate selection.

Q: How does RoHS compliance affect component selection?

A: RoHS compliance is a regulatory requirement in many jurisdictions for electrical and electronic equipment. The 5745174-4 is RoHS compliant, whereas the 745174-4 is non-compliant. Applications subject to RoHS regulations must use the 5745174-4 to satisfy mandatory compliance obligations.

Q: Are there any differences in mechanical fit or installation procedures between the two parts?

A: No. Both components are two-piece backshells with identical shell size (C), cable exit angle (180°), and hardware specifications (4-40 mating screws). Installation procedures and mechanical fit with D-Sub connectors remain unchanged.

Q: What is the difference between bulk and standard packaging for these backshell components?

A: The 5745174-4 is supplied in bulk packaging, which typically provides cost efficiency and streamlined inventory management for production environments. The 745174-4 packaging specification is not defined in available documentation. Bulk packaging does not affect electrical or mechanical performance.

Q: Are both parts compatible with 37-position and HD62-position D-Sub connectors?

A: Yes. Both the 745174-4 and 5745174-4 are compatible with 37pos and HD62pos D-Sub connector sizes. Shell size C designation confirms compatibility across both connector configurations.

Q: What material and plating specifications apply to both components?

A: Both components use identical material composition: metal with zinc alloy construction and nickel over copper plating. This specification ensures corrosion resistance and electrical conductivity for shielded connector applications.
