Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 748475-1 is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility Parameters:

• Connector Style: D-Sub, High Density
• Connector Type: Plug for Male Contacts
• Number of Positions: 44
• Number of Rows: 3
• Shell Size, Connector Layout: 3 (DB, B) High Density
• Contact Type: Signal
• Mounting Type: Free Hanging (In-Line)
• Flange Feature: Cable Side (4-40)
• Features: Backshell, Grounding Indents, Shielded
• Shell Material, Finish: Steel, Tin Plated
• Dielectric Material: Polyamide (PA), Nylon, Glass Filled
• Color: Black

The substitute part TE Connectivity 1658680-1 maintains identical specifications across all these parameters, ensuring direct mechanical and electrical interchangeability. The primary distinction is product status: the substitute is active and RoHS compliant, whereas the original part is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

For New Production Applications: The TE Connectivity 1658680-1 is the appropriate selection for new designs and production builds. This part is active in the manufacturer's product line and carries RoHS compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution in regulated markets.

For Obsolete Equipment Service and Repair: The TE Connectivity 1658680-1 provides direct functional equivalence to the 748475-1 across all mechanical and electrical parameters. The substitute maintains identical connector geometry, contact configuration, mounting interface, and shielding characteristics. The RoHS compliance status of the substitute does not affect interchangeability with legacy systems designed around the original non-compliant part.

Compliance Considerations: Organizations subject to RoHS regulations should transition to the 1658680-1 for all new procurement. The substitute part satisfies both functional requirements and regulatory compliance mandates. Both parts share identical moisture sensitivity classification and environmental handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1658680-1 directly replace the 748475-1 in existing assemblies?

A: Yes. The 1658680-1 maintains identical specifications for connector style, position count, row configuration, shell size, mounting type, flange geometry, and shielding features. Direct mechanical and electrical interchangeability is confirmed across all functional parameters.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 748475-1 is RoHS non-compliant; the 1658680-1 is RoHS compliant. For applications subject to RoHS regulations, the 1658680-1 is the required selection. For legacy equipment not subject to RoHS mandates, both parts function identically. The compliance difference does not affect electrical or mechanical performance.

Q: Are there packaging differences between these parts?

A: The 748475-1 packaging specification is not provided in the technical data. The 1658680-1 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Does the shell finish thickness specification on the 1658680-1 affect compatibility?

A: No. The 1658680-1 specifies a shell finish thickness of 200µin (5.08µm). The 748475-1 finish thickness is not specified. Both parts use identical steel with tin plating as the shell material and finish. The specified thickness on the substitute represents the manufacturing standard for this connector series and does not alter mechanical or electrical interchangeability.

Q: Why is the 748475-1 classified as obsolete?

A: The 748475-1 is no longer in active production. The TE Connectivity 1658680-1 represents the current active equivalent within the AMPLIMITE HDP-22 series. For ongoing procurement and new designs, the 1658680-1 is the supported component.

Q: Are contacts included with either part?

A: No. Both the 748475-1 and 1658680-1 are housing assemblies supplied without contacts. Contacts must be procured separately and installed according to TE Connectivity assembly specifications.

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

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard handling and storage practices for electronic components apply.
