Key Parameters

Substitute Part Grouping Explanation

Substitute components for the Master Appliance Co 10666 are identified based on strict equivalence of the following critical parameters:

• Terminal Type: Butt Splice, Inline, Individual Openings
• Wire Gauge: 18-20 AWG
• Number of Wire Entries: 2
• Termination Method: Crimp
• Insulation Type: Fully Insulated Heat Shrink
• Color: Red
• Series: Proseal™

The substitute part Master Appliance Co 11540 meets all these criteria and is therefore classified as a direct equivalent. The primary distinction between the main part and substitute is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Master Appliance Co 11540 is the direct substitute for the obsolete Master Appliance Co 10666. Both components share identical electrical and mechanical specifications, including terminal type, wire gauge, wire entry configuration, termination method, insulation construction, and color coding.

The primary advantage of selecting part number 11540 is its active product status, ensuring continued availability and supply chain reliability. Additionally, part number 11540 carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and applications requiring modern compliance standards.

Both parts maintain equivalent REACH and ECCN classifications, confirming regulatory parity for export and distribution purposes.

Frequently Asked Questions (FAQ)

Q: Can Master Appliance Co 11540 be used as a direct replacement for Master Appliance Co 10666?

A: Yes. Both components are identical in terminal type, wire gauge (18-20 AWG), wire entry configuration (2 entries), termination method (crimp), insulation type (fully insulated heat shrink), color (red), and series designation (Proseal™). Electrical and mechanical compatibility is complete.

Q: What is the primary difference between these two parts?

A: The main differences are product status and packaging. Part number 10666 is obsolete and supplied individually, while part number 11540 is active and supplied in bulk packaging (100 pieces per pack). Part number 11540 also carries ROHS3 compliance certification.

Q: Does the bulk packaging of part number 11540 affect its suitability as a substitute?

A: No. Packaging configuration does not affect the electrical or mechanical performance of the terminal connector itself. The bulk packaging of part number 11540 is a supply and inventory consideration, not a functional limitation.

Q: Are there any compliance differences between these parts?

A: Part number 11540 carries ROHS3 compliance certification, while part number 10666 is marked as not applicable for RoHS status. Both parts maintain identical REACH and ECCN classifications. For applications requiring modern environmental compliance, part number 11540 is the preferred selection.

Q: What wire gauges are supported by these terminal connectors?

A: Both components support 18-20 AWG wire gauge only. These connectors are not suitable for wire gauges outside this specification range.

Q: How many wires can be terminated with these connectors?

A: Both components feature two wire entries, allowing termination of two individual wires in a butt splice configuration.
