Substitute Part Grouping Explanation
Substitution of the 746881-2 is determined by strict equivalence across the following critical parameters:
Thread Specification: Both the main part and substitute maintain identical 4-40 UNC thread sizing, ensuring mechanical compatibility with connector receptacles.
Physical Dimensions: The length below head measurement of 0.300" (7.62mm) is preserved across all equivalent parts, maintaining proper engagement depth with AMPLIMITE connector housings.
Connector Compatibility: Both parts are designated for use with AMPLIMITE Series HDE and HDP connectors, confirming functional interchangeability within these specific connector families.
Accessory Classification: Both components are classified as slotted jackscrews with clip features, maintaining identical form factor and operational characteristics.
Moisture Sensitivity: MSL rating of 1 (Unlimited) is consistent across substitutes, indicating no moisture-related handling restrictions.
The substitute part 5746881-2 meets all substitution criteria based on these parameters.

Engineering Selection Recommendations
Primary Selection: Part 5746881-2 is the direct active equivalent for obsolete part 746881-2. This substitute maintains full mechanical and functional compatibility across all critical parameters including thread specification, physical dimensions, and connector series compatibility.
Compliance Advantage: The substitute part 5746881-2 carries RoHS Compliant status and REACH Affected designation, providing enhanced regulatory compliance compared to the non-compliant main part. Organizations subject to RoHS or REACH requirements must transition to the 5746881-2 variant.
Product Status: The transition from obsolete (746881-2) to active (5746881-2) status ensures continued availability and supply chain reliability for future procurement cycles.
Packaging Consideration: The substitute is supplied in bag packaging, which is standard for this component category and does not impact functional performance.
Frequently Asked Questions (FAQ)
Q: Can 5746881-2 directly replace 746881-2 in existing AMPLIMITE connector assemblies?
A: Yes. Both parts share identical thread size (4-40 UNC), length below head (0.300"/7.62mm), and are designated for AMPLIMITE Series HDE and HDP connectors. No mechanical or functional modifications are required.
Q: What is the primary reason for substitution?
A: The 746881-2 is classified as obsolete. The 5746881-2 is the active equivalent part, ensuring continued availability and supply chain continuity.
Q: Are there compliance differences between the two parts?
A: Yes. The 5746881-2 is RoHS Compliant and REACH Affected, while the 746881-2 is RoHS non-compliant with undefined REACH status. Organizations operating under RoHS or REACH regulations must use the 5746881-2 variant.
Q: Does packaging differ between these parts?
A: The 746881-2 packaging is not specified in available documentation. The 5746881-2 is supplied in bag packaging, which is standard for D-Sub jackscrew accessories and does not affect functional performance.
Q: Are the moisture sensitivity levels identical?
A: Yes. Both parts carry MSL rating 1 (Unlimited), indicating no moisture-related handling or storage restrictions.
Q: What connector series are these parts compatible with?
A: Both parts are designated for use with AMPLIMITE Series HDE and HDP D-Sub connectors only.
