Engineering Selection Recommendations

The TE Connectivity 1658611-3 is the direct substitute for the obsolete 747053-3 connector. Selection of the 1658611-3 is based on the following engineering criteria:

Product Status Alignment: The 1658611-3 maintains active production status, ensuring long-term availability and supply chain continuity. The obsolete 747053-3 presents supply risk and should be replaced in new designs and system updates.

Electrical and Mechanical Equivalence: All critical electrical parameters (15-position configuration, 1.25A current rating, gold contact finish, phosphor bronze contacts, -55°C to 105°C operating range) and mechanical parameters (D-Sub plug style, free-hanging inline mounting, IDC ribbon cable termination, 4-40 flange mounting) are identical between the two parts.

Compliance and Certification: The 1658611-3 is RoHS compliant, meeting current environmental and regulatory requirements. Both parts carry identical UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels, confirming equivalent reliability characteristics.

Series Continuity: Both connectors belong to the AMPLIMITE HDF-20 series, ensuring design compatibility and interchangeability within existing circuit board layouts and connector mating interfaces.

Frequently Asked Questions (FAQ)

Q: Can the 1658611-3 directly replace the 747053-3 in existing applications?

A: Yes. The 1658611-3 is electrically and mechanically equivalent to the 747053-3. Both connectors share identical pin configurations, current ratings, operating temperature ranges, contact materials, and mounting specifications. Direct substitution is supported without circuit design modifications.

Q: What is the primary advantage of switching to the 1658611-3?

A: The 1658611-3 is in active production status, whereas the 747053-3 is obsolete. This ensures reliable supply availability, reduces procurement lead times, and eliminates the risk of component discontinuation. Additionally, the 1658611-3 is RoHS compliant, meeting modern environmental standards.

Q: Are there any differences in contact finish specifications between these connectors?

A: Both connectors feature gold-plated contacts. The 747053-3 specifies a contact finish thickness of 30.0µin (0.76µm). The 1658611-3 does not specify contact finish thickness in the provided data; however, both parts maintain identical gold contact finish material and phosphor bronze base material.

Q: What is the wire gauge compatibility for the 1658611-3?

A: The 1658611-3 supports 26-28 AWG wire gauge in both stranded and solid configurations for IDC ribbon cable termination. This specification is provided for the substitute part and ensures proper contact engagement and electrical performance.

Q: Are the packaging formats different between these parts?

A: The 747053-3 packaging format is not specified in the provided data. The 1658611-3 is supplied in tube packaging. Packaging differences do not affect electrical or mechanical compatibility; they only impact storage, handling, and inventory management procedures.

Q: Do both connectors meet the same flammability and moisture sensitivity standards?

A: Yes. Both the 747053-3 and 1658611-3 carry identical UL94 V-0 material flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels. These certifications confirm equivalent reliability and environmental performance characteristics.

Q: What is the current inventory status for the 1658611-3?

A: The 1658611-3 has 1909 pieces in new original stock, providing immediate availability for procurement and deployment. The 747053-3 has 1055 pieces in stock but carries obsolete status, making it unsuitable for new system designs.
