Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 747043-1 is based on electrical and mechanical parameter equivalence within the AMPLIMITE HDF-20 series. The substitute part 1658608-1 maintains identical specifications across all critical functional parameters: 37-position configuration, 2-row layout, shell size 4 (DC, C), male pin plug type, IDC ribbon cable termination, steel tin-plated shell construction, gold contact finish, 1.25A current rating, and -55°C to 105°C operating temperature range.

The primary distinction between the main part and substitute is product status and compliance certification. The 747043-1 is obsolete and RoHS non-compliant, while the 1658608-1 is active and ROHS3 compliant. Both parts are manufactured by TE Connectivity AMP Connectors and share identical connector geometry, contact configuration, and electrical performance characteristics. The substitute part is packaged in bulk format and includes specified wire gauge compatibility (26-28 AWG, Stranded or Solid), which is not documented for the main part.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658608-1 is the direct functional equivalent of the obsolete 747043-1 for all applications requiring a 37-position D-Sub plug connector with IDC ribbon cable termination. Selection of the 1658608-1 is supported by the following engineering considerations:

Product Status: The 1658608-1 maintains active product status with TE Connectivity, ensuring ongoing availability, technical support, and supply chain continuity. The 747043-1 is obsolete and subject to discontinuation of manufacturing and support.

Regulatory Compliance: The 1658608-1 is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components in regulated markets. The 747043-1 is RoHS non-compliant and does not satisfy modern procurement standards for many applications and jurisdictions.

Electrical and Mechanical Equivalence: Both parts are identical in connector configuration, pin count, shell size, termination method, current rating, operating temperature range, and contact materials. Direct mechanical and electrical interchangeability is established.

Certification and Standards: Both parts carry identical UL94 V-0 flammability ratings, ECCN classifications, and HTSUS codes, confirming equivalent regulatory standing for the connector category.

Frequently Asked Questions (FAQ)

Q: Can the 1658608-1 directly replace the 747043-1 in existing designs?

A: Yes. The 1658608-1 is mechanically and electrically identical to the 747043-1 across all functional parameters.
