RAF Electronic Hardware 4750-1 Jackscrew Socket for D-Sub Connectors

Part Overview

The RAF Electronic Hardware 4750-1 is a jackscrew socket assembly designed for D-Sub connectors. This component functions as a mechanical fastening accessory that secures D-Sub connector shells through threaded engagement. The part is classified as Active status and is RoHS3 compliant. Equivalent and substitute parts become necessary when managing inventory across multiple suppliers, accommodating regional availability constraints, or standardizing component procurement across manufacturing facilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4750-1 is determined by the following critical parameters:

• Thread Size: 4-40 Socket, 4-40 Screw (must match exactly for mechanical compatibility)
• Accessory Type: Jackscrew Socket (functional classification)
• For Use With/Related Products: D-Sub Connectors (application category)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

The substitute parts listed below meet these core criteria. Dimensional variations within 0.001" tolerance on threaded length are acceptable for D-Sub jackscrew socket applications. Both substitute parts maintain identical thread specifications and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The 4750-1 and 7227 are functionally equivalent, both including hardware as part of the assembly. The 7226 provides an alternative without included hardware.

Dimensional differences between the 4750-1 (0.188") and both Keystone alternatives (0.187") represent a 0.001" variance, which falls within standard manufacturing tolerances for D-Sub jackscrew socket applications and does not affect mechanical fit or functional performance in D-Sub connector assemblies.

Selection between these parts should be based on inventory availability, procurement lead times, and whether hardware inclusion is required for your assembly process.

Frequently Asked Questions (FAQ)

Q: Can 7226 and 7227 be used interchangeably with 4750-1?

A: Yes, both Keystone parts are functionally equivalent substitutes. The primary difference is that 7226 does not include hardware, while 7227 and 4750-1 both include hardware. Thread specifications and dimensional tolerances are compatible across all three parts.

Q: What is the significance of the 0.001" length difference?

A: The threaded length variance (0.188" vs. 0.187") is within standard manufacturing tolerances for D-Sub jackscrew sockets and does not impact compatibility or performance in D-Sub connector applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. The 4750-1, 7226, and 7227 are all RoHS3 compliant, meeting current regulatory requirements for electronic component manufacturing.

Q: Does hardware inclusion affect substitution eligibility?

A: Hardware inclusion is a feature difference, not a substitution barrier. If your assembly process requires pre-assembled hardware, select 4750-1 or 7227. If hardware is sourced separately, 7226 is suitable.

Q: What thread size do these parts use?

A: All three parts use 4-40 Socket and 4-40 Screw threading, ensuring mechanical compatibility across D-Sub connector assemblies.
