Key Parameters

Substitute Part Grouping Explanation

Substitution of the Master Appliance Co 11570 is determined by strict equivalence across the following critical parameters:

Wire Gauge Compatibility: Both the main part and substitute must accommodate 10-12 AWG wire to ensure proper crimp contact and electrical performance.

Stud Configuration: The 3/8" stud size is a fixed mechanical interface requirement. Substitute parts must maintain identical stud diameter and length specifications for direct mounting compatibility.

Terminal Geometry: Circular terminal type ensures consistent contact surface and mechanical fit with standard stud-mounted applications.

Termination Method: Crimp termination is the specified connection method. Substitute parts must use identical crimp barrel design and dimensions.

Insulation Specification: Heat shrink insulation with polyolefin material provides environmental protection and electrical isolation. Substitute parts must maintain this insulation type and material composition.

Color Coding: Yellow insulation serves as a standard industry identifier for 10-12 AWG applications. Substitute parts must retain this color designation.

Mounting Configuration: Free-hanging, in-line mounting type defines the physical orientation and installation method. Substitute parts must support identical mounting characteristics.

Brazed Seam Construction: This feature ensures structural integrity and electrical continuity. Substitute parts must incorporate brazed seam construction.

The Master Appliance Co 11857 meets all specified parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The Master Appliance Co 11857 is the qualified substitute for the obsolete Master Appliance Co 11570. Both components are manufactured by the same supplier and belong to the Multiseal™ series, ensuring design continuity and performance equivalence.

Product Status Consideration: The 11570 is classified as obsolete, while the 11857 maintains active product status. Selection of the 11857 ensures access to current manufacturing inventory and ongoing supplier support.

Compliance Status: The 11857 is ROHS3 compliant, meeting current regulatory requirements for restricted substances. The 11570 is not applicable for RoHS classification due to its obsolete status. Both parts maintain REACH Unaffected status, indicating no conflict with chemical substance regulations.

Electrical and Mechanical Equivalence: All critical parameters—wire gauge, stud size, terminal geometry, termination method, insulation specification, and mounting configuration—are identical between the two parts. This equivalence ensures direct functional substitution without circuit redesign or mechanical modification.

Packaging Consideration: The 11857 is supplied in bulk packaging (50-pack configuration), whereas the 11570 packaging specification is not defined. Bulk packaging of the 11857 may require inventory management adjustment for applications requiring smaller quantities.

Frequently Asked Questions (FAQ)

Q: Can the Master Appliance Co 11857 be used as a direct replacement for the 11570 in existing applications?

A: Yes. The 11857 is electrically and mechanically equivalent to the 11570 across all specified parameters, including wire gauge (10-12 AWG), stud size (3/8"), terminal type (circular), termination method (crimp), insulation specification (heat shrink polyolefin), and mounting configuration (free-hanging, in-line). Direct substitution is supported without modification.

Q: Why is the 11570 classified as obsolete?

A: The 11570 has been discontinued by the manufacturer. The 11857 represents the current active product offering with identical electrical and mechanical specifications. Transition to the 11857 ensures continued access to supply and compliance with current manufacturing standards.

Q: What is the difference in packaging between the 11570 and 11857?

A: The 11857 is supplied in bulk packaging containing 50 pieces per pack. The 11570 packaging specification is not documented. For applications requiring smaller quantities, the bulk packaging of the 11857 may necessitate inventory management planning.

Q: Are there any compliance differences between the two parts?

A: The 11857 is ROHS3 compliant, meeting current regulatory requirements for restricted substances in electrical and electronic equipment. The 11570 is not applicable for RoHS classification due to its obsolete status. Both parts maintain REACH Unaffected status. Selection of the 11857 ensures compliance with current environmental regulations.

Q: What parameters determine substitution eligibility for this terminal connector?

A: Substitution is determined by equivalence across wire gauge (10-12 AWG), stud size (3/8"), terminal type (circular), termination method (crimp), insulation type (heat shrink polyolefin), color (yellow), mounting configuration (free-hanging, in-line), and brazed seam construction. All parameters must match for direct substitution.

Q: Is the 11857 available in current inventory?

A: Yes. The 11857 is classified as active product status with 874 pieces in current stock, ensuring immediate availability for procurement and deployment.
