Key Parameters

Substitute Part Grouping Explanation

Substitution of the 749765-3 is determined by strict equivalence across the following critical parameters:

• Connector Series Compatibility: Both parts must be designed for AMPLIMITE Series HDF and HDP connectors
• Accessory Type: Both must function as jackscrew socket components
• Thread Specifications: Identical M2.6 socket and 4-40 screw thread sizing
• Physical Dimensions: Matching length below head of 0.312" (7.92mm)
• Functional Classification: Both classified as D-Sub female screw lock components

The substitute part 5749765-3 meets all these criteria, providing direct functional equivalence while offering improved compliance status and active product availability.

Parameter Comparison

Engineering Selection Recommendations

The 5749765-3 serves as the direct active equivalent to the obsolete 749765-3. Selection of the substitute part is based on the following engineering considerations:

Product Status: The 749765-3 is classified as obsolete, creating supply chain risk. The 5749765-3 maintains active product status, ensuring continued availability and manufacturer support.

Regulatory Compliance: The 5749765-3 achieves RoHS compliance, whereas the 749765-3 is RoHS non-compliant. For applications subject to RoHS directives, the 5749765-3 is the required selection. Additionally, the 5749765-3 is REACH unaffected, eliminating regulatory exposure associated with the REACH-affected 749765-3.

Functional Equivalence: Both parts maintain identical specifications across all critical parameters including thread sizing, physical dimensions, series compatibility, and moisture sensitivity classification. No functional degradation or performance variation occurs with substitution.

Supply Availability: The 5749765-3 maintains higher inventory levels (1021 pieces) compared to the 749765-3 (679 pieces), supporting sustained procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5749765-3 be used as a direct replacement for the 749765-3 in existing AMPLIMITE connector assemblies?

A: Yes. The 5749765-3 is functionally equivalent across all critical parameters including thread specifications (M2.6 socket, 4-40 screw), physical dimensions (0.312" below head), and series compatibility (AMPLIMITE HDF, HDP). No mechanical or electrical modifications are required.

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

A: The 749765-3 is RoHS non-compliant, while the 5749765-3 is RoHS compliant. Applications subject to RoHS directives (including EU markets and regulated industries) require the 5749765-3. The 749765-3 cannot be used in these applications.

Q: Does the REACH status difference affect component selection?

A: Yes. The 749765-3 is REACH affected, indicating the presence of substances of very high concern (SVHC). The 5749765-3 is REACH unaffected, eliminating regulatory documentation and compliance requirements. For applications in REACH-regulated regions, the 5749765-3 is the appropriate selection.

Q: Are there any dimensional or thread compatibility concerns when substituting these parts?

A: No. Both parts share identical specifications for length below head (0.312" / 7.92mm) and thread sizing (M2.6 socket, 4-40 screw). Mechanical fit and fastening performance are identical.

Q: Why is the 749765-3 classified as obsolete?

A: The 749765-3 has been superseded by the 5749765-3, which offers improved regulatory compliance (RoHS compliant, REACH unaffected) and maintains active manufacturing status. The 5749765-3 is the current production equivalent.

Q: What is the Moisture Sensitivity Level (MSL) classification for these parts?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures.

Q: Are there packaging differences between the 749765-3 and 5749765-3?

A: Packaging information is not specified in the technical data for either part. Contact the manufacturer for specific packaging configuration details if required for procurement or assembly processes.
