Engineering Selection Recommendations

The TE Connectivity 1658611-2 is the direct functional equivalent of the 747053-2 across all electrical and mechanical parameters. Selection of 1658611-2 is supported by the following engineering considerations:

Product Status: The 747053-2 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 1658611-2 maintains active product status with confirmed inventory of 1298 pieces, ensuring supply chain reliability.

Regulatory Compliance: The 1658611-2 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The 747053-2 is RoHS non-compliant, which may present regulatory constraints in applications subject to RoHS directives.

Electrical and Mechanical Equivalence: Both connectors maintain identical specifications across connector style, pin configuration, shell size, termination method, current rating, temperature range, contact materials, and flammability rating. These parameters define functional interchangeability for IDC ribbon cable applications.

Series Continuity: Both parts belong to the AMPLIMITE HDF-20 series, confirming design lineage and manufacturing consistency.

Frequently Asked Questions (FAQ)

Q: Can the 1658611-2 directly replace the 747053-2 in existing applications?

A: Yes. The 1658611-2 is electrically and mechanically equivalent to the 747053-2. Both connectors share identical specifications for connector type, pin count, shell size, termination method, current rating, and operating temperature range. Direct substitution is supported for applications currently using the 747053-2.

Q: What is the primary reason for substitution?

A: The 747053-2 is obsolete and subject to limited availability. The 1658611-2 is an active product with confirmed inventory, ensuring long-term supply continuity and design support.

Q: Are there differences in RoHS compliance between these parts?

A: Yes. The 747053-2 is RoHS non-compliant, while the 1658611-2 is ROHS3 compliant. Applications subject to RoHS directives or customer requirements for RoHS compliance should use the 1658611-2.

Q: Do both connectors support the same ribbon cable specifications?

A: Both connectors use IDC termination for ribbon cable. The 1658611-2 specifies wire gauge compatibility of 26-28 AWG, stranded or solid. This specification should be verified for compatibility with existing ribbon cable assemblies.

Q: Is packaging a consideration for substitution?

A: The 1658611-2 is supplied in bulk packaging. If specific packaging requirements exist for the application or supply chain, packaging specifications should be confirmed with the supplier.

Q: Are the contact finish specifications identical?

A: Both connectors feature gold contact finish. The 747053-2 specifies a contact finish thickness of 30.0µin (0.76µm). The 1658611-2 does not specify contact finish thickness in the provided data. Contact finish thickness should be confirmed if this parameter is critical for the application.

Q: What is the operating temperature range for both connectors?

A: Both the 747053-2 and 1658611-2 operate across the identical temperature range of -55°C to 105°C, supporting applications across industrial and extended temperature environments.

Q: Are both connectors rated for the same current?

A: Yes. Both connectors are rated for 1.25A, supporting equivalent power delivery specifications for signal and low-power applications.
