Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part (747951-1) and the equivalent part (1658654-1) is based on matching the following critical parameters:

• Connector Style & Type: Both are D-Sub receptacle housings for female contacts
• Position Configuration: Identical 9-position, 2-row layout
• Shell Size & Layout: Both use Shell Size 1 (DE, E) configuration
• Mounting Architecture: Both feature free hanging, in-line mounting with cable-side 4-40 flange
• Shielding & Features: Both include backshell and shielded design
• Material Composition: Both use steel with tin plating and polyamide dielectric
• Contact Type: Both designated for signal contacts
• Series Compatibility: Both belong to the AMPLIMITE HDP-20 series

These parameters establish direct functional and mechanical interchangeability. The substitute part maintains all critical electrical and mechanical characteristics required for connector mating and system integration.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: TE Connectivity 1658654-1

The substitute part 1658654-1 is the recommended selection for new designs and ongoing procurement. This recommendation is based on the following factors:

• Product Status: The substitute part maintains active product status, ensuring long-term availability and manufacturer support, whereas the main part 747951-1 is classified as obsolete.

• Regulatory Compliance: The substitute part is ROHS3 compliant and REACH unaffected, providing superior compliance posture for applications subject to environmental and hazardous substance regulations. The main part carries RoHS non-compliant status and vendor-undefined REACH status.

• Functional Equivalence: Both parts maintain identical electrical and mechanical specifications across all critical parameters, including connector configuration, mounting architecture, shielding design, and material composition.

• Inventory Availability: The substitute part demonstrates higher inventory levels (2100 units) compared to the main part (866 units), supporting supply chain continuity.

• Mechanical Compatibility: The substitute part includes specified shell finish thickness (200µin / 5.08µm), providing documented coating specification for quality assurance.

Secondary Consideration: TE Connectivity 747951-1

The main part may be retained for legacy system maintenance where existing inventory is available and regulatory compliance requirements are not applicable. However, new procurement should transition to the substitute part.

Frequently Asked Questions (FAQ)

Q: Are the 747951-1 and 1658654-1 mechanically interchangeable?

A: Yes. Both parts are D-Sub receptacle housings with identical 9-position, 2-row configuration, Shell Size 1 (DE, E) layout, cable-side 4-40 flange mounting, and shielded backshell design. They are mechanically interchangeable in all applications.

Q: Can the 1658654-1 substitute for the 747951-1 in existing assemblies?

A: Yes. The substitute part maintains all critical mechanical and electrical parameters required for connector mating and system integration. No design modifications are required.

Q: What is the difference in shell finish thickness between these parts?

A: The main part (747951-1) does not specify shell finish thickness. The substitute part (1658654-1) specifies 200µin (5.08µm) tin plating thickness, providing documented coating specification for quality control purposes.

Q: Why is the 747951-1 classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation and market transition. The substitute part 1658654-1 represents the active equivalent within the AMPLIMITE HDP-20 series.

Q: Are there compliance differences between these parts?

A: Yes. The substitute part (1658654-1) is ROHS3 compliant and REACH unaffected, while the main part (747951-1) is RoHS non-compliant with vendor-undefined REACH status. For applications subject to environmental regulations, the substitute part is required.

Q: What is the packaging difference?

A: The main part packaging is not specified. The substitute part is supplied in bulk packaging, which is standard for connector housing components.

Q: Do these parts require specific contact types?

A: Both parts are housings designed for female contacts. Contacts are not included with either part and must be selected separately based on application requirements. The housing itself is contact-agnostic and accepts standard D-Sub female contacts compatible with Shell Size 1 (DE, E) configuration.

Q: Are both parts suitable for shielded applications?

A: Yes. Both parts feature shielded design with backshell, making them suitable for applications requiring electromagnetic interference (EMI) protection.

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

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
