TE Connectivity 747538-1 D-Sub Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 747538-1 is a D-Sub connector housing plug designed for 15-position male contact applications. This component functions as the shell assembly for D-Sub connectors in the AMPLIMITE HDP-20 series, featuring a 2-row configuration with grounding indents and shielding. The part is classified as obsolete, making identification of active equivalent components necessary for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without design modification.

Critical Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug for Male Contacts
• Position count: 15 positions
• Row configuration: 2 rows
• Shell size and layout: 2 (DA, A)
• Mounting configuration: Free Hanging (In-Line)
• Flange type: Housing/Shell (Unthreaded)
• Features: Grounding Indents and Shielded construction
• Shell material and finish: Steel with Tin Plating
• Dielectric composition: Polyamide (PA), Nylon, Glass Filled
• Housing color: Black
• Series designation: AMPLIMITE HDP-20

The substitute part 1658647-1 meets all specified parameters and is classified as an active product, providing continuity for applications currently using the obsolete 747538-1.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658647-1 is the direct substitute for the obsolete 747538-1. Both components are manufactured by TE Connectivity within the AMPLIMITE HDP-20 series and share identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The 747538-1 is classified as obsolete, while the 1658647-1 is active. For new designs and ongoing procurement, the 1658647-1 should be specified to ensure supply chain continuity and manufacturer support.

Compliance Advantage: The substitute part 1658647-1 carries ROHS3 compliance certification, whereas the main part is RoHS non-compliant. The substitute also carries REACH Unaffected status, providing improved regulatory alignment for applications subject to environmental compliance requirements.

Packaging Difference: The substitute part is supplied in bulk packaging, whereas the main part packaging specification is not provided. This difference does not affect functional or mechanical interchangeability.

Shell Finish Specification: The substitute part specifies a shell finish thickness of 200µin (5.08µm), providing documented tin plating thickness. This specification is not provided for the main part but does not indicate a difference in performance or compatibility.

Both parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 1658647-1 directly replace the 747538-1 in existing applications?

A: Yes. The 1658647-1 is a direct substitute with identical connector style, position count, row configuration, shell size, mounting type, and all electrical and mechanical specifications. No design modification is required for direct substitution.

Q: What is the primary reason for substitution?

A: The 747538-1 is classified as obsolete. The 1658647-1 is an active product from the same manufacturer and series, ensuring continued availability and manufacturer support.

Q: Are there compliance differences between these parts?

A: Yes. The 1658647-1 is ROHS3 compliant and carries REACH Unaffected status, while the 747538-1 is RoHS non-compliant with vendor-undefined REACH status. For applications subject to environmental regulations, the 1658647-1 provides improved compliance alignment.

Q: Do these parts require different contact types or pin configurations?

A: No. Both parts are designed for 15-position male contact applications with identical row configuration and shell layout. Contact compatibility remains unchanged.

Q: What is the difference in packaging between these parts?

A: The 1658647-1 is supplied in bulk packaging. The main part packaging specification is not documented. This difference affects procurement and handling but does not impact functional or mechanical compatibility.

Q: Are the shell materials and finishes identical?

A: Both parts feature steel shells with tin plating. The substitute part specifies a finish thickness of 200µin (5.08µm). This documented specification does not indicate a difference in performance or durability.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling or storage requirements during assembly or deployment.

Q: Can the 747538-1 and 1658647-1 be used interchangeably in the same connector assembly?

A: Yes. Both parts are mechanically and electrically identical across all specified parameters and are designed for the same AMPLIMITE HDP-20 series applications.
