TE Connectivity 747522-1 D-Sub Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 747522-1 is a D-Sub connector housing plug designed for 9-position male contact applications. This component functions as the shell assembly for AMPLIMITE HDP-20 series D-Sub connectors, providing the mechanical structure and shielding for signal-level connections in free-hanging inline configurations.

The 747522-1 carries an obsolete product status, indicating it is no longer in active production. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where this connector housing is specified or functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub connector housings is determined by strict equivalence across mechanical and electrical parameters. The following criteria establish whether a part qualifies as a direct substitute for the 747522-1:

Required Matching Parameters:

• Connector style (D-Sub)
• Connector type (Plug for Male Contacts)
• Number of positions (9)
• Number of rows (2)
• Shell size and connector layout (1 / DE, E)
• Contact type (Signal)
• Mounting type (Free Hanging / In-Line)
• Flange feature (Housing/Shell, Unthreaded)
• Shell material and finish (Steel, Tin Plated)
• Dielectric material (Polyamide / Nylon, Glass Filled)
• Color (Black)
• Series compatibility (AMPLIMITE HDP-20)

The substitute part 1658645-1 meets all required matching parameters and is therefore classified as a direct functional equivalent to the obsolete 747522-1.

Parameter Comparison

Engineering Selection Recommendations

The 1658645-1 is the direct substitute for the obsolete 747522-1 based on complete mechanical and electrical parameter equivalence within the AMPLIMITE HDP-20 series.

Primary Selection Basis:

The 1658645-1 maintains identical form, fit, and function across all critical connector parameters: 9-position D-Sub plug housing, male contact configuration, shell size DE/E layout, free-hanging mounting, steel tin-plated construction, and polyamide dielectric material.

Compliance Advantages:

The substitute part 1658645-1 offers improved regulatory compliance compared to the main part. It carries RoHS Compliant status, whereas the 747522-1 is RoHS non-compliant. Additionally, the 1658645-1 is REACH Unaffected, compared to the REACH Affected status of the 747522-1. These compliance improvements support modern procurement requirements and regulatory alignment.

Production Status:

The 1658645-1 is in active production with 2375 units in stock, ensuring availability for current and future applications. The 747522-1 is obsolete and no longer manufactured.

Packaging Consideration:

The 1658645-1 is supplied in bulk packaging, which is standard for connector housing components in production environments.

Frequently Asked Questions (FAQ)

Q: Can the 1658645-1 directly replace the 747522-1 in existing designs?

A: Yes. The 1658645-1 is a direct functional equivalent. All mechanical dimensions, electrical characteristics, contact positions, mounting configuration, and material specifications are identical. No design modification is required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The 747522-1 is obsolete and RoHS non-compliant, while the 1658645-1 is in active production and RoHS Compliant. The 1658645-1 also specifies shell finish thickness at 200µin (5.08µm) and is REACH Unaffected. Functionally and mechanically, both parts are equivalent.

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

A: Yes. Both housings are designed for the same 9-position male contact set within the AMPLIMITE HDP-20 series. Contact compatibility is determined by the 9-position, 2-row DE/E shell size specification, which is identical for both parts.

Q: What does "Plug for Male Contacts" mean?

A: This designation indicates the housing is a plug connector (the mating half that inserts into a receptacle) configured to accept male contacts. The male contacts insert into the housing cavity and establish electrical connection with corresponding female contacts in a mating receptacle.

Q: Why is the shell finish thickness specified for the substitute but not the main part?

A: The 747522-1 specification does not include shell finish thickness data, likely due to its obsolete status and older documentation standards. The 1658645-1 provides complete specification data, including the 200µin (5.08µm) tin plating thickness, which is standard for this connector series.

Q: Does the bulk packaging of the 1658645-1 affect compatibility?

A: No. Packaging format does not affect the connector's mechanical or electrical function. Bulk packaging is standard for connector housings and does not impact performance or interchangeability.

Q: Are there any operating temperature or mating cycle limitations?

A: Operating temperature and mating cycle specifications are not provided in the available data for either part. These parameters should be referenced in the complete AMPLIMITE HDP-20 series documentation if required for specific application requirements.

Q: What is the significance of the RoHS and REACH compliance differences?

A: RoHS Compliance indicates the 1658645-1 meets restrictions on hazardous substances in electrical and electronic equipment. REACH Unaffected status indicates the part does not contain substances of very high concern requiring registration. These compliance improvements make the 1658645-1 suitable for applications with modern regulatory requirements, whereas the 747522-1 may face procurement restrictions in regulated markets.
