Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 748676-1 is determined by strict equivalence across all critical mechanical and electrical parameters. The substitute part must maintain identical specifications for:

• Accessory type and form factor (Two Piece Backshell)
• Position count (9 positions)
• Compatible shell size (E)
• Compatible D-Sub connector sizes (9pos and HD15pos)
• Cable exit orientation (180°)
• Shielding configuration (Shielded)
• Cable type compatibility (Round)
• Material composition and plating (Metal, Zinc Alloy with Nickel over Copper)
• Hardware specifications (Assembly Hardware, Grommets, Mating Screws 4-40)

The substitute part 5748676-1 meets all these criteria and provides an active, currently manufactured alternative with improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 5748676-1 is the direct substitute for the obsolete 748676-1. Both components are manufactured by TE Connectivity and belong to the AMPLIMITE HD-20 series. They are mechanically and electrically identical across all functional parameters.

The 5748676-1 offers the following advantages:

• Active product status with current manufacturing availability
• ROHS3 compliance, meeting current environmental regulations
• REACH Affected status, indicating compliance with chemical substance restrictions
• Bulk packaging option for production environments

The 748676-1 carries RoHS non-compliant status and Vendor Undefined REACH status, making it unsuitable for new designs or applications subject to regulatory compliance requirements.

For applications requiring the 9 Position Two Piece Backshell with 180° cable exit and shielding in the AMPLIMITE HD-20 series, the 5748676-1 provides full functional equivalence with superior compliance and availability characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 748676-1 and 5748676-1 mechanically interchangeable?

A: Yes. Both components are Two Piece Backshells with identical dimensions, shell size (E), position count (9), cable exit angle (180°), and hardware specifications (Mating Screws 4-40). They mount identically to 9pos and HD15pos D-Sub connectors.

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

A: The primary differences are product status and regulatory compliance. The 748676-1 is obsolete and RoHS non-compliant. The 5748676-1 is an active product with ROHS3 compliance and defined REACH status. All mechanical and electrical specifications are identical.

Q: Can I use the 5748676-1 as a direct replacement in existing designs?

A: Yes. The 5748676-1 is a direct substitute with identical form factor, function, and connector compatibility. No design modifications are required.

Q: What does the "E" shell size designation mean?

A: Shell size E is a standard D-Sub backshell size classification. Both the 748676-1 and 5748676-1 are compatible with 9pos and HD15pos D-Sub connectors using this shell size.

Q: Why is the 748676-1 listed as obsolete?

A: The 748676-1 has been discontinued by TE Connectivity. The 5748676-1 represents the current active product line replacement with equivalent specifications.

Q: Are there packaging differences between these parts?

A: The 748676-1 packaging is listed as unspecified. The 5748676-1 is supplied in Bulk packaging, suitable for production assembly environments.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the 748676-1 and 5748676-1 carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the significance of ROHS3 compliance on the 5748676-1?

A: ROHS3 compliance indicates the 5748676-1 meets current Restriction of Hazardous Substances regulations, making it suitable for applications in regulated markets and new product designs. The obsolete 748676-1 does not carry this certification.
