Key Parameters

Substitute Part Grouping Explanation

Substitution of the 745175-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5745175-2 maintains identical specifications for connector positioning, shielding characteristics, cable interface geometry, and hardware compatibility.

The following parameters establish substitution validity:

• Number of Positions: 50 (exact match required)
• Compatible Shell Size: D (exact match required)
• Compatible D-Sub Size: 50pos and HD78pos (exact match required)
• Cable Exit: 180° (exact match required)
• Shielding: Shielded (exact match required)
• Cable Type: Round (exact match required)
• Accessory Type: Two Piece Backshell (exact match required)
• Material Composition: Metal, Zinc Alloy (exact match required)
• Plating: Nickel over Copper (exact match required)
• Hardware: Assembly Hardware, Strain Relief with 4-40 Mating Screws (exact match required)

Parameter Comparison

Engineering Selection Recommendations

The 5745175-2 serves as the direct functional equivalent to the obsolete 745175-2. Selection of the substitute part is based on the following engineering criteria:

Functional Equivalence: All electrical and mechanical parameters are identical. The 5745175-2 maintains the same 50-position configuration, D-shell size compatibility, 180° shielded cable exit, and hardware specifications as the original part.

Product Status: The 5745175-2 carries Active product status, ensuring continued availability and manufacturer support. The 745175-2 is classified as Obsolete, limiting future procurement options.

Compliance Improvement: The 5745175-2 is RoHS Compliant, whereas the 745175-2 is RoHS non-compliant. The substitute part also provides defined REACH status (REACH Unaffected) compared to the undefined status of the original part.

Regulatory Classification: Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, indicating no change in export control or tariff treatment.

Packaging: The 5745175-2 is supplied in Bulk packaging, compared to the unspecified packaging of the 745175-2. This difference does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 5745175-2 be used as a direct replacement for the 745175-2 in existing assemblies?

A: Yes. The 5745175-2 is functionally identical to the 745175-2 across all electrical and mechanical parameters. Both parts are 50-position D-shell backshells with 180° shielded cable exit, identical material composition, plating, and hardware specifications. Direct substitution is supported without design modification.

Q: What is the difference between the 745175-2 and 5745175-2?

A: The primary differences are product status and compliance certifications. The 745175-2 is Obsolete with RoHS non-compliant status and undefined REACH status. The 5745175-2 is Active, RoHS Compliant, and has defined REACH status (REACH Unaffected). All functional specifications are identical.

Q: Are there any compatibility concerns when substituting the 5745175-2 for the 745175-2?

A: No compatibility concerns exist. Both parts are designed for the same D-Sub connector configurations (50pos and HD78pos), support identical cable types (round), and feature the same 4-40 mating screw hardware. Mechanical and electrical interfaces are fully compatible.

Q: Does the packaging difference between the two parts affect compatibility?

A: No. The packaging difference (Bulk for 5745175-2 versus unspecified for 745175-2) is a supply chain consideration only and does not affect the functional performance or compatibility of the component.

Q: Why is the 745175-2 classified as Obsolete?

A: The 745175-2 carries Obsolete status, indicating that TE Connectivity AMP Connectors has discontinued active production and support. The 5745175-2 is the Active equivalent and is the recommended part for new procurement.

Q: Is the 5745175-2 suitable for applications requiring RoHS compliance?

A: Yes. The 5745175-2 is RoHS Compliant, making it suitable for applications with RoHS requirements. The original 745175-2 is RoHS non-compliant and would not satisfy such requirements.

Q: What is the inventory status of these parts?

A: The 745175-2 has 645 pieces in stock (New Original). The 5745175-2 has 754 pieces in stock (New Original). Both parts are currently available.

Q: Are the export control classifications the same for both parts?

A: Yes. Both the 745175-2 and 5745175-2 share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. No change in export control or tariff treatment occurs when substituting between these parts.
