Key Parameters

Substitute Part Grouping Explanation

Substitution of the Keystone Electronics 7227 with the RAF Electronic Hardware 4750-1 is based on functional equivalence across the following critical parameters:

Thread Specification: Both parts utilize 4-40 socket and 4-40 screw threading, ensuring mechanical compatibility with D-Sub connector fastening systems.

Accessory Classification: Both components are classified as jackscrew socket assemblies for D-Sub connectors, confirming identical functional purpose.

Dimensional Compatibility: The threaded portion length and overall length below head are nominally equivalent (0.187" versus 0.188", representing a tolerance variation of 0.001"), maintaining mechanical fit within D-Sub connector assemblies.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent component selection.

Hardware Inclusion: Both parts include hardware as standard features, confirming functional parity in assembly completeness.

Parameter Comparison

Engineering Selection Recommendations

Both the Keystone Electronics 7227 and RAF Electronic Hardware 4750-1 are active products with equivalent functional specifications for D-Sub connector jackscrew socket applications. Selection between these components should be based on:

Regulatory Compliance: Both parts satisfy ROHS3 and REACH requirements, making either suitable for applications with environmental compliance mandates.

Dimensional Tolerance: The 0.001" dimensional variance between parts falls within standard mechanical tolerances for D-Sub connector hardware and does not affect functional compatibility.

Inventory Availability: The RAF Electronic Hardware 4750-1 maintains higher inventory levels (1019 units) compared to the Keystone Electronics 7227 (861 units), which may influence procurement decisions based on lead time requirements.

Product Status: Both components maintain active product status, confirming ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Are the Keystone Electronics 7227 and RAF Electronic Hardware 4750-1 mechanically interchangeable?

A: Yes. Both parts share identical thread specifications (4-40 socket and 4-40 screw), equivalent dimensional characteristics within standard tolerances, and identical functional classification as jackscrew sockets for D-Sub connectors.

Q: What is the significance of the 0.001" dimensional difference between the two parts?

A: The dimensional variance (0.187" versus 0.188") represents a tolerance variation well within standard mechanical engineering practices for fastener hardware and does not affect functional performance or compatibility with D-Sub connector assemblies.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the Keystone Electronics 7227 and RAF Electronic Hardware 4750-1 are ROHS3 compliant and REACH unaffected, satisfying equivalent environmental and regulatory standards.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts?

A: The Keystone Electronics 7227 specifies MSL 1 (Unlimited), while the RAF Electronic Hardware 4750-1 lists MSL as Not Applicable. This difference does not affect substitution compatibility, as MSL classifications apply to component storage and handling rather than functional performance.

Q: Are both parts available in bulk packaging?

A: Yes. Both the Keystone Electronics 7227 and RAF Electronic Hardware 4750-1 are supplied in bulk packaging, consistent with standard D-Sub connector hardware distribution formats.

Q: Can these parts be used interchangeably in existing D-Sub connector assemblies?

A: Yes. The functional equivalence across thread specification, dimensional characteristics, and hardware inclusion confirms interchangeability in D-Sub connector applications.
