TE Connectivity 745563-4 AMPLIMITE HDE-20 Jackscrew Socket Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745563-4 is a female screwlock jackscrew socket accessory designed for the AMPLIMITE Series HDE-20 D-Sub connector family. This component provides mechanical fastening capability through a 4-40 threaded socket configuration. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and system maintenance. Substitute parts must maintain identical mechanical and electrical compatibility with the AMPLIMITE HDE-20 series while meeting current regulatory compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 745563-4 is determined by strict equivalence across the following critical parameters:

• Accessory Type: Must be Jackscrew Socket
• Compatible Series: Must be AMPLIMITE Series HDE-20
• Thread Size: Must be 4-40 Socket, 4-40 Screw
• Length - Threaded Portion Below Head: Must be 0.250" (6.35mm)
• Length - Below Head: Must be 0.250" (6.35mm)
• Hardware Inclusion: Must include hardware

The substitute part 5745563-4 meets all mechanical and functional requirements for direct substitution. The primary distinction between the main part and its substitute is product status (obsolete versus active) and regulatory compliance posture (RoHS non-compliant versus RoHS compliant). Packaging configuration differs (bulk versus 10-piece bag), reflecting the transition from obsolete to active product lines.

Parameter Comparison

Engineering Selection Recommendations

The part 5745563-4 is the direct functional equivalent to 745563-4 and is suitable for all applications requiring AMPLIMITE Series HDE-20 jackscrew socket accessories. Selection of 5745563-4 is supported by the following factors:

• Product Status: 5745563-4 maintains active product status, ensuring continued availability and manufacturer support
• RoHS Compliance: 5745563-4 is RoHS compliant, meeting regulatory requirements for restricted substances in electrical and electronic equipment
• REACH Compliance: 5745563-4 has defined REACH status, providing regulatory clarity for supply chain documentation
• Mechanical Equivalence: All critical dimensions, thread specifications, and hardware configurations are identical to the obsolete part
• Series Compatibility: Both parts are designated for AMPLIMITE Series HDE-20, ensuring mechanical and electrical fit

For new designs or system refreshes, 5745563-4 is the appropriate selection. For legacy system maintenance requiring the exact obsolete part number, 5745563-4 provides functional substitution with improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can 5745563-4 be used as a direct replacement for 745563-4 in existing AMPLIMITE HDE-20 assemblies?

A: Yes. Both parts are jackscrew sockets with identical thread size (4-40), identical threaded portion length (0.250"), and identical below-head length (0.250"). They are mechanically and functionally interchangeable for AMPLIMITE Series HDE-20 connectors.

Q: What is the difference between the bulk packaging of 745563-4 and the 10-piece bag packaging of 5745563-4?

A: The main part (745563-4) was supplied in bulk packaging format typical of obsolete product lines. The substitute (5745563-4) is supplied in 10-piece bag packaging, reflecting current active product distribution standards. The individual component specifications remain identical.

Q: Does the RoHS compliance difference between 745563-4 and 5745563-4 affect mechanical compatibility?

A: No. RoHS compliance is a regulatory material composition requirement and does not alter mechanical dimensions, thread specifications, or physical fit. Both parts maintain identical mechanical compatibility with AMPLIMITE Series HDE-20 connectors.

Q: Are there any electrical performance differences between 745563-4 and 5745563-4?

A: No. Both parts are mechanical fastening accessories (jackscrew sockets) with no active electrical function. Electrical performance of the connector assembly is determined by the D-Sub connector body and contact elements, not by the jackscrew socket accessory.

Q: What does "Hardware Included" mean for these jackscrew socket parts?

A: Both parts include the necessary fastening hardware (screws and associated components) required for installation and operation of the jackscrew socket on AMPLIMITE Series HDE-20 connectors. No additional hardware procurement is required.

Q: Is 5745563-4 available in the same bulk quantities as the obsolete 745563-4?

A: 5745563-4 is supplied in 10-piece bag packaging. For applications requiring larger quantities, multiple bags can be ordered to achieve the required total unit count.
