Substitute Part Grouping Explanation

Substitution of the Keystone Electronics 4059 is determined by the following critical parameters:

  • Tab Width: The 0.205" (5.21mm) dimension is the primary mechanical interface specification
  • Terminal Type: Angled 90° configuration for specific mounting orientation requirements
  • Gender: Male connector designation for mating compatibility
  • Termination Method: Screw, Rivet, Stud connection type
  • Insulation Type: Non-insulated design for direct electrical contact applications
  • Mounting Configuration: Board and chassis mounting capability
  • Tab Count: 8 tabs for multi-point connection requirements
  • Contact Material: Brass composition for electrical conductivity and corrosion resistance
  • Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The identified substitute part (Keystone Electronics 4119) shares identical specifications across all critical parameters except for tab width dimension, which represents a controlled variation within the same product family.

Engineering Selection Recommendations

The Keystone Electronics 4119 is designated as the manufacturer-recommended substitute for the obsolete Keystone Electronics 4059. Both components maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications requiring these certifications.

The primary distinction between these components is the tab width specification: 0.205" (5.21mm) for the 4059 versus 0.250" (6.35mm) for the 4119. This dimensional difference requires mechanical compatibility assessment within the specific application context, including connector receptacle dimensions and mounting hole spacing.

The 4119 substitute offers the advantage of active product status with confirmed inventory availability (1078 pcs), whereas the 4059 is obsolete. Selection of the 4119 should be contingent upon mechanical fit verification within the target application assembly.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the Keystone 4059?

A: The Keystone 4059 is classified as obsolete. The Keystone 4119 is the manufacturer-recommended active equivalent, ensuring continued supply chain access and production support.

Q: Are the 4059 and 4119 electrically interchangeable?

A: Both components share identical electrical specifications: male gender, 90° angled terminal type, screw/rivet/stud termination, non-insulated design, brass contact material, and 8-tab configuration. Electrical compatibility is confirmed.

Q: What is the key mechanical difference between these parts?

A: The tab width differs: the 4059 features 0.205" (5.21mm) width, while the 4119 features 0.250" (6.35mm) width. This dimension must be verified against the receiving connector receptacle and mounting hole specifications in the target application.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 4059 and 4119 are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for applications requiring these certifications.

Q: Is the 4119 currently available?

A: Yes. The Keystone 4119 is classified as active product status with 1078 pcs in new original inventory, providing reliable supply chain access compared to the obsolete 4059.

Q: Can the 4119 be used as a direct drop-in replacement?

A: Mechanical compatibility must be verified. While electrical and functional specifications are identical, the increased tab width (0.250" versus 0.205") requires confirmation that the receiving connector receptacle and mounting configuration accommodate this dimensional change.
