Master Appliance Co 11571 Yellow 10 Stud Spade Terminal Connector

Part Overview

The Master Appliance Co 11571 is an insulated spade terminal connector designed for crimp termination of 10-12 AWG wire gauges. This component features a yellow polyolefin insulation with heat shrink protection and a brazed seam construction. The terminal is configured with a #10 stud for free-hanging in-line mounting applications.

The 11571 carries an obsolete product status, making it necessary to identify active equivalent components for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or system reconfiguration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 11571 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Mandatory Matching Parameters:

• Wire gauge range: 10-12 AWG
• Stud size: #10 Stud
• Termination method: Crimp
• Insulation material: Polyolefin
• Insulation configuration: Heat shrink
• Terminal type: Standard
• Mounting type: Free Hanging (In-Line)
• Color: Yellow
• Construction: Brazed seam
• Manufacturer: Master Appliance Co
• Series: Multiseal™

The 11571 is classified as obsolete. Substitute parts must be active products to ensure continued availability and supply chain reliability. All substitute components must originate from the same manufacturer and product series to maintain design consistency and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Master Appliance Co 11861

The 11861 is the direct active equivalent to the obsolete 11571. All electrical and mechanical parameters are identical across wire gauge, stud size, termination method, insulation material, color, and mounting configuration. Both components are manufactured by Master Appliance Co within the Multiseal™ series, ensuring design and performance consistency.

The 11861 carries an active product status, providing assured long-term availability and supply chain continuity. The substitute part exceeds the original specification by achieving ROHS3 compliance, indicating enhanced environmental and regulatory alignment. Both parts maintain identical REACH unaffected status and EAR99 export classification.

The 11861 is available in bulk packaging (50-piece packs), which may require inventory management adjustment compared to the original packaging configuration. This packaging difference does not affect electrical or mechanical compatibility.

Direct substitution of 11861 for 11571 requires no circuit modifications, connector redesign, or system reconfiguration. The components are mechanically and electrically interchangeable for all applications originally specified for the 11571.

Frequently Asked Questions (FAQ)

Q: Can the 11861 be used as a direct replacement for the 11571 in existing assemblies?

A: Yes. The 11861 is electrically and mechanically identical to the 11571 across all specified parameters. Direct substitution is possible without modification to circuits, connectors, or assembly procedures.

Q: What is the primary reason for substitution?

A: The 11571 is classified as obsolete. The 11861 is the active equivalent part, ensuring continued procurement availability and supply chain reliability.

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

A: The 11861 achieves ROHS3 compliance, while the 11571 lists RoHS status as not applicable. Both parts maintain identical REACH unaffected status. The 11861 meets or exceeds all regulatory requirements of the original part.

Q: Does the packaging difference affect compatibility?

A: No. The 11861 is supplied in bulk 50-piece packaging, while the 11571 packaging is not specified. Packaging configuration does not affect electrical or mechanical performance. Inventory management and ordering quantities may require adjustment based on application requirements.

Q: What wire gauges are supported by the 11861?

A: The 11861 supports 10-12 AWG wire gauges, identical to the 11571. The #10 stud configuration accommodates this wire gauge range for crimp termination applications.

Q: Is the insulation material the same in both parts?

A: Yes. Both the 11571 and 11861 use polyolefin insulation with heat shrink protection. The insulation color is yellow in both components.

Q: Can the 11861 be used in the same mounting configuration as the 11571?

A: Yes. Both parts are configured for free-hanging in-line mounting. The mechanical mounting interface is identical.
