Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 747053-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector style (D-Sub)
• Connector type (Plug, Male Pins)
• Number of positions (9)
• Number of rows (2)
• Shell size and layout (1, DE/E)
• Mounting type (Free Hanging, In-Line)
• Termination method (IDC, Ribbon Cable)
• Contact material (Phosphor Bronze)
• Contact finish (Gold)
• Current rating (1.25A)
• Operating temperature range (-55°C to 105°C)
• Flange feature (Housing/Shell 4-40)
• Dielectric material (Thermoplastic)
• Series designation (AMPLIMITE HDF-20)

The substitute part 1658611-4 meets all mandatory matching parameters and is therefore classified as a direct equivalent for the obsolete 747053-4.

Frequently Asked Questions (FAQ)

Q: Can the 1658611-4 be used as a direct replacement for the 747053-4 in existing designs?

A: Yes. The 1658611-4 is a direct functional equivalent. All electrical and mechanical parameters match the 747053-4 specifications, including connector type, pin configuration, contact materials, current ratings, and operating temperature range. No design modifications are required.

Q: What is the difference between the 747053-4 and 1658611-4?

A: The primary differences are product status and regulatory compliance. The 747053-4 is obsolete and RoHS non-compliant, while the 1658611-4 is an active product with ROHS3 compliance. Both connectors are electrically and mechanically identical.

Q: Are there any compatibility concerns when substituting the 1658611-4 for the 747053-4?

A: No compatibility concerns exist. Both connectors feature identical shell sizes (DE/E), pin counts (9 positions), mounting configurations (free-hanging inline), and termination methods (IDC ribbon cable). They are fully interchangeable.

Q: Does the 1658611-4 support the same wire gauge specifications?

A: The 1658611-4 is specified for 26-28 AWG stranded or solid wire. The 747053-4 does not have wire gauge specifications provided in the technical data. Both connectors use IDC termination for ribbon cable applications.

Q: What is the significance of the RoHS compliance difference?

A: The 1658611-4 is ROHS3 compliant, meeting current European Union Restriction of Hazardous Substances regulations. The 747053-4 is RoHS non-compliant. For applications subject to RoHS requirements or environmental compliance mandates, the 1658611-4 is the appropriate selection.

Q: Is the 1658611-4 available in the same packaging as the 747053-4?

A: The 1658611-4 is supplied in bulk packaging. The 747053-4 packaging specification is not provided in the technical data. Both are available as new original stock from TE Connectivity.

Q: What is the current rating for both connectors?

A: Both the 747053-4 and 1658611-4 are rated for 1.25A continuous current operation.

Q: Are both connectors suitable for the same temperature range applications?

A: Yes. Both connectors operate across the identical temperature range of -55°C to 105°C, supporting applications in extreme thermal environments.

Q: What contact material is used in both connectors?

A: Both connectors use phosphor bronze contacts with gold plating. The 747053-4 specifies a contact finish thickness of 30.0µin (0.76µm). The 1658611-4 contact finish thickness is not specified in the technical data.
