Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-745174-7 is determined by strict equivalence across the following critical parameters:

• Accessory Type: Two Piece Backshell (mechanical form factor)
• Number of Positions: 37 (connector pin count compatibility)
• Compatible Shell Size: C (physical envelope)
• Compatible D-Sub Size: 37pos and HD62pos (interface compatibility)
• Cable Type: Round (cable geometry)
• Cable Exit Angle: 180° (strain relief orientation)
• Shielding: Shielded (electromagnetic protection requirement)
• Material Composition: Metal, Zinc Alloy (structural and corrosion resistance)
• Plating: Nickel over Copper (contact and environmental protection)
• Color: Silver (finish specification)
• Series: AMPLIMITE (product line consistency)

The substitute part 2-5745174-7 maintains full equivalence across all specified parameters while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 2-5745174-7 is the direct active equivalent for the obsolete 2-745174-7. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 2-5745174-7 maintains Active product status, ensuring continued availability and manufacturer support. The 2-745174-7 is classified as Obsolete, creating supply chain risk and limiting access to technical documentation.

Regulatory Compliance: The 2-5745174-7 is ROHS3 Compliant and REACH Affected, meeting current environmental and hazardous substance regulations. The 2-745174-7 is RoHS non-compliant with undefined REACH status, presenting compliance barriers for applications subject to regulatory requirements.

Functional Equivalence: Both parts maintain identical specifications across all critical mechanical and electrical parameters, including connector position count, shell size, cable exit angle, shielding configuration, and material composition. Direct mechanical and electrical interchangeability is established.

Hardware Enhancement: The 2-5745174-7 includes specified Mating Screws 4-40 as part of the assembly hardware specification, providing additional clarity on fastening requirements compared to the generic assembly hardware designation of the main part.

Frequently Asked Questions (FAQ)

Q: Are the 2-745174-7 and 2-5745174-7 mechanically interchangeable?

A: Yes. Both parts are Two Piece Backshells with identical specifications for shell size (C), position count (37), cable type (Round), cable exit angle (180°), and shielding configuration. Mechanical interchangeability is confirmed across all specified parameters.

Q: What is the primary difference between these two parts?

A: The 2-5745174-7 is the active production equivalent of the obsolete 2-745174-7. The substitute part offers ROHS3 compliance and defined REACH status, whereas the original part is RoHS non-compliant with undefined REACH status. Both parts are functionally and mechanically equivalent.

Q: Can the 2-5745174-7 be used as a direct replacement in existing designs?

A: Yes. The 2-5745174-7 maintains full compatibility with 37-position D-Sub connectors in Shell Size C and HD62pos configurations. No design modifications are required for substitution.

Q: What connector types are compatible with these backshells?

A: Both backshells are compatible with 37-position D-Sub connectors and HD62-position connectors using Shell Size C. The 180° cable exit angle accommodates round cable assemblies with straight-back strain relief orientation.

Q: Does packaging differ between the two parts?

A: The 2-745174-7 packaging is not specified in available documentation. The 2-5745174-7 is supplied in Bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Are there any restrictions on using the 2-5745174-7 in regulated applications?

A: The 2-5745174-7 is ROHS3 Compliant and REACH Affected, meeting current environmental regulations. Applications subject to RoHS or REACH requirements should use the 2-5745174-7. The original 2-745174-7 does not meet these compliance standards.
