Key Parameters

Substitute Part Grouping Explanation

Substitution of the 747523-1 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector style (D-Sub)
• Connector type (Receptacle for Female Contacts)
• Number of positions (9)
• Number of rows (2)
• Shell size and connector layout (1 / DE, E)
• Mounting type (Free Hanging / In-Line)
• Flange feature (Housing/Shell, Unthreaded)

Electrical and Physical Parameters:

• Contact type (Signal)
• Shielding feature (Shielded)
• Shell material and finish (Steel, Tin Plated)
• Color (Black)
• Series designation (AMPLIMITE HDP-20)

Regulatory and Compliance Parameters:

• ECCN classification (EAR99)
• HTSUS code (8538.90.8180)
• Moisture Sensitivity Level (MSL 1 / Unlimited)

The substitute part 1658646-1 maintains full equivalence across all mechanical, electrical, and physical parameters. Differences in dielectric material composition, product status, and regulatory compliance do not affect functional interchangeability within the specified connector system.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 1658646-1

The 1658646-1 is the direct functional equivalent for the obsolete 747523-1. This substitute maintains complete mechanical and electrical compatibility across all critical parameters including connector style, position count, shell size, mounting configuration, and shielding characteristics.

Compliance Advantages:

The 1658646-1 offers significant regulatory improvements over the 747523-1:

• RoHS3 Compliance: The substitute meets current Restriction of Hazardous Substances requirements, whereas the main part is non-compliant. This is critical for new designs and systems subject to environmental regulations.

• REACH Status: The substitute is classified as REACH Unaffected, eliminating concerns related to substances of very high concern (SVHC) that apply to the main part.

• Active Production Status: The 1658646-1 is in active production with confirmed inventory availability (1545 pieces), ensuring reliable supply for current and future requirements.

Material Specification:

The dielectric material differs between parts (Thermoplastic versus Polyamide with glass filling). The substitute's polyamide composition provides enhanced mechanical strength and thermal stability while maintaining functional equivalence within the D-Sub connector system. The specified shell finish thickness of 200µin (5.08µm) on the substitute ensures consistent corrosion protection.

Selection Criteria:

Use the 1658646-1 for all new designs, production runs, and field replacements. The obsolete status of the 747523-1 combined with the superior compliance profile and active availability of the 1658646-1 makes this substitution the standard engineering choice.

Frequently Asked Questions (FAQ)

Q: Can the 1658646-1 directly replace the 747523-1 in existing assemblies?

A: Yes. The 1658646-1 is mechanically and electrically equivalent to the 747523-1 across all critical parameters. Both are 9-position D-Sub receptacle housings in the AMPLIMITE HDP-20 series with identical shell size (DE/E), mounting type (free hanging), and shielding configuration. Direct substitution is supported without design modification.

Q: What is the significance of the dielectric material difference?

A: The main part uses Thermoplastic dielectric material, while the substitute uses Polyamide (PA) with glass filling. Both materials function equivalently as insulators within the connector housing. The polyamide composition in the substitute provides improved mechanical rigidity and thermal performance, representing a material enhancement rather than a functional change.

Q: Why is the 747523-1 listed as obsolete?

A: TE Connectivity has discontinued manufacturing of the 747523-1. The 1658646-1 represents the current production equivalent within the AMPLIMITE HDP-20 series. Obsolescence does not indicate a design flaw; rather, it reflects the manufacturer's transition to updated part numbers and improved compliance standards.

Q: Are there compliance differences between these parts?

A: Yes. The 1658646-1 is RoHS3 compliant and REACH Unaffected, while the 747523-1 is RoHS non-compliant and REACH Affected. For applications subject to environmental regulations or customer compliance requirements, the 1658646-1 is the required choice. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Q: What is the packaging difference?

A: The main part packaging is not specified in available documentation. The 1658646-1 is supplied in bulk packaging, which is standard for connector housing components. Bulk packaging does not affect functional performance or interchangeability.

Q: Is the shell finish thickness specification important?

A: The 1658646-1 specifies a shell finish thickness of 200µin (5.08µm) tin plating. This specification ensures consistent corrosion protection and electrical conductivity. The main part does not include finish thickness documentation. The specified thickness on the substitute represents a defined quality standard for the tin-plated steel shell.

Q: Can I use the 747523-1 if I have existing inventory?

A: Existing inventory of the 747523-1 can be used in applications where RoHS and REACH compliance are not required. However, for new designs, production transitions, or systems subject to environmental regulations, transition to the 1658646-1 is recommended to ensure long-term supply continuity and regulatory compliance.

Q: Are contacts included with either part?

A: No. Both the 747523-1 and 1658646-1 are housing assemblies only. Contacts are not included and must be sourced separately. Ensure that selected contacts are compatible with the 9-position, 2-row DE/E shell size configuration.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture sensitivity concerns. This classification simplifies storage, handling, and logistics without requiring special moisture control measures during warehousing or transportation.
