Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Master Appliance Co 11581 is determined by strict equivalence across the following critical parameters:

• Wire Gauge Compatibility: 14-16 AWG
• Stud/Tab Size: 3/8 Stud
• Terminal Type: Circular configuration
• Termination Method: Crimp connection
• Insulation Specification: Heat shrink insulation with polyolefin material
• Color Designation: Blue
• Mounting Configuration: Free Hanging (In-Line)
• Brazed Seam Construction: Required feature

The substitute part 11854 maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being packaging configuration and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The Master Appliance Co 11854 serves as the direct functional equivalent to the obsolete 11581 model. Both components share identical electrical and mechanical specifications, ensuring direct interchangeability in applications requiring 14-16 AWG ring terminal connectors with 3/8" stud configuration.

The 11854 offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The part achieves ROHS3 compliance, meeting current regulatory requirements for new system designs and procurement cycles. Both components maintain REACH unaffected status and identical ECCN/HTSUS classifications, confirming regulatory equivalence.

Selection of the 11854 is appropriate for applications where the original 11581 is no longer procurable due to obsolescence. The packaging difference (bulk 50-pack configuration for 11854 versus individual unit packaging for 11581) does not affect functional performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 11854 directly replace the 11581 in existing applications?

A: Yes. The 11854 maintains identical wire gauge (14-16 AWG), stud size (3/8"), terminal type (circular), termination method (crimp), insulation specification (heat shrink polyolefin), color (blue), and mounting configuration (free hanging in-line). All electrical and mechanical parameters are equivalent.

Q: What is the primary difference between these two part numbers?

A: The 11581 is obsolete with individual unit packaging, while the 11854 is an active product supplied in bulk 50-pack configuration. The 11854 also carries ROHS3 compliance certification.

Q: Are there any compatibility concerns when substituting the 11854 for the 11581?

A: No compatibility concerns exist. Both components are manufactured by Master Appliance Co within the Multiseal™ series and share identical specifications across all critical parameters that determine terminal performance and installation compatibility.

Q: Does the packaging difference affect the terminal specifications?

A: No. Packaging configuration does not alter the electrical or mechanical properties of the individual terminal connector. The 11854 bulk packaging provides the same terminal specifications as the 11581.

Q: Are both parts compliant with current regulatory standards?

A: The 11854 is ROHS3 compliant and REACH unaffected. The 11581, listed as obsolete, carries "not applicable" RoHS status. For new designs and current procurement, the 11854 meets active regulatory requirements.
