Key Parameters

Substitute Part Grouping Explanation

Substitution of the Master Appliance Co 11576 is determined by strict equivalence across the following critical parameters:

Wire Gauge Compatibility: Both the main part and substitute must accommodate 18-20 AWG wire to ensure proper crimp contact and electrical performance.

Terminal Geometry: The circular terminal type with #10 stud configuration defines the mechanical interface. Substitutes must maintain identical stud size to ensure compatibility with existing mounting points and assemblies.

Termination Method: Crimp termination is the specified connection method. Substitutes must employ identical crimp technology to maintain assembly process compatibility.

Insulation Specification: Heat shrink polyolefin insulation with brazed seam construction defines the environmental protection and mechanical integrity. Substitutes must replicate this insulation system.

Mounting Configuration: Free hanging in-line mounting type must be preserved to maintain form factor compatibility in existing designs.

Color Coding: Red color designation must be maintained for circuit identification and traceability standards.

The Master Appliance Co 11851 meets all these criteria and qualifies as a direct substitute for the obsolete 11576 model.

Parameter Comparison

Engineering Selection Recommendations

The Master Appliance Co 11851 is the direct substitute for the obsolete 11576 model. Both components are manufactured by Master Appliance Co within the Multiseal™ series and share identical electrical and mechanical specifications across all critical parameters.

The 11851 offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 11851 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and manufacturing processes. The 11576, listed as not applicable for RoHS status, reflects its obsolete classification.

Both parts maintain REACH unaffected status, confirming compliance with chemical substance regulations. The ECCN classification (EAR99) and HTSUS code (8536.90.4000) are identical, indicating equivalent trade and export compliance profiles.

For applications requiring the 11576 specification, the 11851 provides complete functional and mechanical equivalence with enhanced regulatory compliance and assured supply availability.

Frequently Asked Questions (FAQ)

Q: Can the Master Appliance Co 11851 be used as a direct replacement for the 11576 in existing assemblies?

A: Yes. The 11851 is a direct substitute with identical wire gauge (18-20 AWG), terminal type (circular), stud size (#10), termination method (crimp), insulation system (polyolefin heat shrink with brazed seam), mounting configuration (free hanging in-line), and color (red). All critical parameters match the original specification.

Q: What is the primary difference between the 11576 and 11851?

A: The 11576 is obsolete with not applicable RoHS status, while the 11851 is an active product with ROHS3 compliance. The 11851 is supplied in bulk packaging (50-pack configuration), whereas the 11576 packaging specification is not defined. Functionally and mechanically, both components are equivalent.

Q: Are there any compatibility concerns when substituting the 11851 for the 11576?

A: No compatibility concerns exist. The 11851 maintains identical specifications for all parameters that determine mechanical fit and electrical performance: wire gauge, terminal geometry, stud size, crimp termination, insulation material and construction, and mounting type.

Q: Does the 11851 meet current regulatory requirements?

A: Yes. The 11851 carries ROHS3 compliance certification and maintains REACH unaffected status, meeting current environmental and chemical substance regulations. The 11576, as an obsolete component, does not carry current compliance certifications.

Q: What packaging considerations apply to the 11851?

A: The 11851 is supplied in bulk packaging (50-pack configuration). The original 11576 packaging specification is not defined in available documentation. Bulk packaging of the 11851 may require inventory management adjustments for applications previously sourced in alternative package quantities.
