Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 749197-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Accessory Type: Two Piece Backshell
• Number of Positions: 100
• Cable Exit Angle: 180°
• Shielding Configuration: Shielded
• Primary Material: Metal
• Material Composition: Metal, Zinc
• Plating Specification: Nickel over Copper
• Hardware Configuration: Assembly Hardware, Strain Relief
• Features: Spring Lock
• Color: Silver
• Series Compatibility: AMPLIMITE .050 III

The substitute part 5749197-1 meets all mandatory matching parameters. The primary distinction between the main part and its substitute is the product status transition from Obsolete to Active, along with corresponding RoHS compliance upgrade and packaging specification change.

Engineering Selection Recommendations

For New Production Applications: The 5749197-1 is the appropriate selection for new designs and production builds. This part carries Active product status, ensuring long-term availability and supply chain stability. The ROHS3 compliance certification aligns with current environmental and regulatory requirements for electronic component manufacturing and distribution.

For Maintenance and Repair of Existing Systems: The 5749197-1 provides functional and mechanical equivalence to the 749197-1 for field replacement and repair applications. All electrical and mechanical parameters remain identical, ensuring drop-in compatibility within existing assemblies designed for the 749197-1 specification.

Compliance Considerations: Applications subject to RoHS3 compliance mandates must utilize the 5749197-1. The 749197-1, classified as RoHS non-compliant, is restricted in regulated markets and supply chains enforcing environmental compliance standards.

Frequently Asked Questions (FAQ)

Q: Can the 5749197-1 directly replace the 749197-1 in existing assemblies?

A: Yes. The 5749197-1 provides complete functional and mechanical equivalence. All critical parameters including position count, cable exit angle, shielding configuration, material composition, plating specification, and hardware features are identical. The connector integrates without modification into assemblies originally specified for the 749197-1.

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

A: The 5749197-1 represents an active production variant with ROHS3 compliance certification, while the 749197-1 is classified as Obsolete with RoHS non-compliance status. The functional specifications and mechanical interfaces remain unchanged between the two parts.

Q: Are there packaging differences between 749197-1 and 5749197-1?

A: Yes. The 749197-1 packaging specification is not defined in the available data. The 5749197-1 is supplied in Bag packaging. Verify packaging requirements for your specific application and procurement process.

Q: Which part should be specified for new designs?

A: The 5749197-1 is the appropriate specification for new designs. Active product status ensures availability throughout the design lifecycle and into production. ROHS3 compliance supports regulatory requirements in current manufacturing environments.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 749197-1 and 5749197-1 are manufactured by TE Connectivity AMP Connectors and belong to the AMPLIMITE .050 III series.

Q: What does the "Two Piece Backshell" designation indicate?

A: The Two Piece Backshell design consists of separable components that assemble around the cable and connector interface. This configuration provides strain relief, shielding, and mechanical protection while allowing field assembly and disassembly for maintenance and repair operations.

Q: Is the 180° cable exit angle critical for substitution?

A: Yes. The 180° cable exit angle is a mandatory matching parameter. This specification defines the cable routing direction relative to the connector body. Substitution is valid only when the cable exit angle matches exactly.
