Key Parameters

Substitute Part Grouping Explanation

Substitution of the 175753-9 is based on functional equivalence across the following critical parameters:

Matching Parameters:

• Number of Positions: 100
• Cable Exit Angle: 180°
• Shielding: Shielded
• Cable Type: Round
• Primary Material: Metal
• Category: D-Sub, D-Shaped Connectors

The substitute part 5749854-1 maintains identical functional specifications for position count, cable exit configuration, and shielding requirements. Both parts accommodate round cable types and provide metal construction with strain relief hardware. The substitute part differs in series designation (AMPLIMITE .050 III versus CHAMP .050 II), material composition (Zinc with Nickel over Copper plating versus Brass), and accessory configuration (Two Piece Backshell versus Two Piece Shield with Cover), but these differences do not affect core electrical or mechanical compatibility for the specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5749854-1 is the appropriate selection for applications currently specified with 175753-9. The substitute maintains all critical functional parameters: 100-position configuration, 180° cable exit, shielded design, and round cable accommodation.

Status Consideration: The 175753-9 is classified as Obsolete, while 5749854-1 is Active. Active product status ensures continued availability, manufacturing support, and compliance with current regulatory standards.

Compliance Consideration: The substitute part 5749854-1 carries ROHS3 Compliant certification, whereas the main part status is Not applicable. This compliance upgrade aligns with current environmental and regulatory requirements for electronic component manufacturing and distribution.

Material and Plating Differences: The substitute employs Zinc with Nickel over Copper plating, compared to the main part's Brass composition. Both material systems provide equivalent corrosion resistance and electrical conductivity for D-Sub backshell applications. The Nickel over Copper plating system in the substitute part offers enhanced durability and environmental protection.

Series Evolution: The transition from CHAMP .050 II to AMPLIMITE .050 III represents a product line evolution within TE Connectivity's connector portfolio, with the newer series incorporating updated design standards and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can 5749854-1 directly replace 175753-9 in existing assemblies?

A: Yes. Both parts share identical specifications for the critical functional parameters: 100 positions, 180° cable exit angle, shielded configuration, and round cable type. The parts are mechanically and electrically compatible for applications specified with the original part number.

Q: What is the significance of the Obsolete status for 175753-9?

A: Obsolete status indicates that TE Connectivity has discontinued manufacturing and support for this part number. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. Transition to the active substitute part 5749854-1 is necessary for sustained production and supply chain reliability.

Q: How do the material differences between the two parts affect performance?

A: The main part uses Brass with Thermoplastic components, while the substitute uses Zinc with Nickel over Copper plating. Both material systems provide adequate electrical conductivity and corrosion resistance for D-Sub backshell applications. The Nickel over Copper plating in the substitute offers enhanced environmental protection and durability.

Q: Does the RoHS3 compliance of 5749854-1 create any compatibility issues?

A: No. RoHS3 compliance indicates adherence to current environmental standards for hazardous substance restrictions. This compliance status is beneficial for applications subject to environmental regulations and does not create incompatibility with existing connector systems.

Q: Are there packaging differences between these parts?

A: The main part 175753-9 packaging is not specified in available documentation. The substitute part 5749854-1 is supplied in Bag packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the difference between "Two Piece Shield with Cover" and "Two Piece Backshell"?

A: Both configurations provide two-piece construction for backshell assembly. The terminology reflects design variations in TE Connectivity's product nomenclature across different series generations. Functional performance for shielding and cable exit configuration remains equivalent.

Q: Are the mating screw specifications important for substitution?

A: The substitute part 5749854-1 includes Mating Screws 2-56 as part of its assembly hardware specification. Verify that your application accommodates standard 2-56 fasteners. The main part strain relief hardware should be compatible with this fastener specification.

Q: What is the inventory status for these parts?

A: The main part 175753-9 shows 1064 pieces in stock as new original inventory. The substitute part 5749854-1 shows 847 pieces in stock as new original inventory. Availability may vary by distributor and time of inquiry.
