TE Connectivity 747952-1 D-Sub Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 747952-1 is a D-Sub connector housing plug designed for 9-position male contact applications. This component functions as the outer shell assembly for D-Sub connectors in the AMPLIMITE HDP-20 series, featuring a shielded design with grounding indents and cable-side flange mounting. The part is classified as obsolete, necessitating identification of active equivalent components to maintain supply chain continuity and ensure long-term product availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 747952-1 is based on electrical and mechanical parameter equivalence within the D-Sub connector housing category. The substitute part 1658655-1 maintains identical specifications across all critical functional parameters: connector style, type, position count, row configuration, shell size layout, mounting method, flange design, shell material composition, dielectric material, and feature set. Both components are manufactured by TE Connectivity AMP Connectors within the same AMPLIMITE HDP-20 series.

The primary distinction between the main part and its substitute is product status and regulatory compliance. The 747952-1 is obsolete and RoHS non-compliant, while 1658655-1 is an active product with ROHS3 compliance. The substitute also includes specified shell finish thickness (200µin / 5.08µm), whereas the main part does not document this parameter.

Substitution is valid when the following parameters are matched:

• Connector style and type
• Position and row configuration
• Shell size and connector layout
• Mounting type and flange feature
• Shell material and finish type
• Dielectric material composition
• Feature set (backshell, grounding indents, shielding)

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658655-1 is the direct functional equivalent for the obsolete 747952-1 D-Sub connector housing plug. Selection of 1658655-1 is supported by:

Product Status: The 1658655-1 is an active product with confirmed current manufacturing and availability, whereas 747952-1 is obsolete and subject to supply discontinuation.

Regulatory Compliance: The 1658655-1 carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions. The 747952-1 is RoHS non-compliant and does not satisfy modern regulatory requirements for new equipment designs or many regional markets.

Mechanical and Electrical Equivalence: All functional parameters are identical between the two parts, including connector configuration, shell construction, mounting method, and feature set. The 1658655-1 includes documented shell finish thickness specification (200µin / 5.08µm), providing additional process control documentation.

Series Continuity: Both components belong to the AMPLIMITE HDP-20 series, ensuring design compatibility and interchangeability within existing connector systems.

For applications currently using 747952-1, transition to 1658655-1 is recommended to ensure long-term supply security, regulatory compliance, and access to active product support.

Frequently Asked Questions (FAQ)

Q: Can 1658655-1 directly replace 747952-1 in existing designs?

A: Yes. The 1658655-1 is mechanically and electrically equivalent to 747952-1. Both components share identical connector style, position count, shell size, mounting type, flange design, shell material, and feature set. Direct substitution is valid for all applications currently using 747952-1.

Q: What is the primary reason to transition from 747952-1 to 1658655-1?

A: The 747952-1 is classified as obsolete, indicating discontinued manufacturing and declining availability. The 1658655-1 is an active product with current production and supply continuity. Additionally, 1658655-1 is ROHS3 compliant, whereas 747952-1 is RoHS non-compliant, making 1658655-1 necessary for regulatory compliance in new designs and many markets.

Q: Are there any performance differences between these parts?

A: No performance differences exist. Both components are manufactured by TE Connectivity AMP Connectors within the same AMPLIMITE HDP-20 series and maintain identical electrical and mechanical specifications. The 1658655-1 includes documented shell finish thickness (200µin / 5.08µm), which is a manufacturing specification detail not provided for 747952-1.

Q: What is the packaging difference between 747952-1 and 1658655-1?

A: The 747952-1 packaging is not specified in available documentation. The 1658655-1 is supplied in bulk packaging. Confirm packaging requirements with your procurement or supply chain department for specific application needs.

Q: Are both parts compatible with the same male contacts?

A: Both 747952-1 and 1658655-1 are plug housings designed for male contacts in 9-position D-Sub configurations. Contact compatibility is determined by the contact part number and series specification, not the housing. Verify contact part numbers separately to ensure complete connector assembly compatibility.

Q: What is the moisture sensitivity level for these components?

A: Both 747952-1 and 1658655-1 carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements. Standard storage conditions are acceptable for both parts.

Q: Are there any export or trade restrictions on these parts?

A: Both components are classified under ECCN EAR99 and HTSUS 8538.90.8180. Verify current export regulations with your compliance department, as classification and restrictions may vary by destination and application.
