Engineering Selection Recommendations

The TE Connectivity 5748472-1 is the direct substitute for the obsolete 748472-1 connector. Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring direct compatibility in existing applications.

Primary Selection Basis:

The 5748472-1 is recommended for new procurement and replacement applications based on the following factors:

1. Product Status: The 5748472-1 maintains active product status, ensuring continued availability and manufacturer support. The 748472-1 is classified as obsolete and subject to discontinuation.

2. Regulatory Compliance: The 5748472-1 is RoHS Compliant and carries defined REACH status (REACH Unaffected), whereas the 748472-1 is RoHS non-compliant with undefined REACH status. This distinction is critical for applications subject to environmental and regulatory requirements.

3. Functional Equivalence: All electrical and mechanical parameters are identical, including connector style, position count, row configuration, contact type, mounting method, shell material, and shielding features.

4. Packaging: The 5748472-1 is supplied in bulk packaging, supporting efficient inventory management and procurement workflows.

5. Inventory Availability: The 5748472-1 has 1143 pieces in stock compared to 959 pieces for the obsolete variant, providing improved supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the 5748472-1 directly replace the 748472-1 in existing applications?

A: Yes. The 5748472-1 is electrically and mechanically equivalent to the 748472-1 across all specified parameters. Both connectors feature identical 78-position, 4-row D-Sub high-density configurations with matching shell materials, dielectric properties, and mounting characteristics. Direct substitution is supported without design modifications.

Q: What is the difference between the 748472-1 and 5748472-1?

A: The primary differences are product status and regulatory compliance. The 748472-1 is obsolete and RoHS non-compliant, while the 5748472-1 is an active product with RoHS compliance and defined REACH status. The 5748472-1 also includes specified shell finish thickness (200µin / 5.08µm) and bulk packaging. All electrical and mechanical specifications remain identical.

Q: Why is the 748472-1 listed as obsolete?

A: The 748472-1 has been superseded by the 5748472-1 in the manufacturer's product line. The newer variant offers improved regulatory compliance and active product support. Existing inventory of the 748472-1 remains available, but new designs should specify the 5748472-1.

Q: Are there any compatibility concerns when switching from 748472-1 to 5748472-1?

A: No compatibility concerns exist. Both parts are from the same AMPLIMITE HDP-22 series and maintain identical specifications for connector style, position count, contact type, mounting method, shell material, and shielding. The parts are mechanically and electrically interchangeable.

Q: Does the packaging difference affect compatibility?

A: No. The 748472-1 is supplied in unspecified packaging, while the 5748472-1 is supplied in bulk packaging. Packaging affects only procurement and inventory handling, not connector functionality or compatibility.

Q: What is the significance of RoHS compliance for this connector?

A: RoHS compliance indicates the connector meets Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. The 5748472-1's RoHS compliance is required for applications subject to environmental regulations or customer specifications. The 748472-1's non-compliance may restrict its use in regulated industries.

Q: Can I use the 748472-1 if RoHS compliance is not required?

A: Yes, the 748472-1 can be used in applications where RoHS compliance is not mandated. However, the 5748472-1 is recommended for all new designs due to its active product status and improved regulatory positioning.

Q: What does "Contacts Not Included" mean?

A: Both the 748472-1 and 5748472-1 are housing shells only. Individual male contacts must be procured separately and inserted into the housing. The connector housing itself does not include pre-installed contacts.

Q: Are the shell finish specifications identical?

A: Both parts feature steel shells with tin plating. The 5748472-1 specifies a finish thickness of 200µin (5.08µm), while the 748472-1 does not provide this specification. The finish material and type are equivalent.
