Key Parameters

Substitute Part Grouping Explanation

Substitution of Master Appliance Co 10838 is determined by strict equivalence across the following critical parameters:

• Tab Width: 0.250" (6.35mm) — determines mechanical compatibility with mating connectors
• Wire Gauge: 18-20 AWG — establishes current-carrying capacity and crimp die requirements
• Gender: Female — defines connector orientation and mating interface
• Termination Method: Crimp — specifies assembly process compatibility
• Insulation Type: Fully Insulated Heat Shrink — ensures electrical safety and environmental protection
• Contact Material and Finish: Brass with Tin finish — maintains electrical conductivity and corrosion resistance
• Series: Solderseal™ — confirms product family compatibility

The substitute part Master Appliance Co 11844 meets all these critical parameters identically, establishing direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Master Appliance Co 11844 is the direct functional equivalent for applications currently specified with part number 10838. The substitute part maintains identical electrical and mechanical specifications across all critical parameters: tab width, wire gauge, gender, termination method, insulation type, contact material, and contact finish.

The primary distinction between the two parts is product status and regulatory compliance. Part 10838 is obsolete and carries no RoHS designation, while part 11844 is active and ROHS3 compliant. For new designs or ongoing production requiring this connector specification, part 11844 is the appropriate selection. The active status of 11844 ensures continued availability and supply chain support.

Both parts share identical REACH and ECCN classifications, confirming equivalent regulatory standing for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can Master Appliance Co 11844 be used as a direct replacement for 10838 in existing applications?

A: Yes. The 11844 is functionally equivalent across all critical electrical and mechanical parameters: 0.250" tab width, 18-20 AWG wire gauge, female gender, crimp termination, fully insulated heat shrink construction, brass tin-plated contacts, and red color designation. No circuit redesign or connector interface modification is required.

Q: What is the primary reason for substituting 10838 with 11844?

A: Part 10838 is classified as obsolete, creating supply chain risk. Part 11844 is active and maintains identical specifications, ensuring continued availability and production support.

Q: Are there packaging differences between 10838 and 11844?

A: Yes. Part 10838 is supplied in standard packaging, while part 11844 is supplied in bulk packaging (50-piece packs). This difference affects order quantities and storage considerations but does not impact electrical or mechanical compatibility.

Q: Does the ROHS3 compliance of 11844 affect compatibility with 10838 applications?

A: No. ROHS3 compliance indicates that part 11844 meets current environmental standards for hazardous substance restrictions. This is a regulatory advantage and does not alter the electrical or mechanical function of the connector. Applications specified for 10838 are fully compatible with the ROHS3-compliant 11844.

Q: Are the contact materials and finishes identical between the two parts?

A: Yes. Both parts feature brass contacts with tin finish, ensuring identical electrical conductivity, corrosion resistance, and current-carrying capacity.

Q: What is the Moisture Sensitivity Level (MSL) difference, and does it matter?

A: Part 10838 lists MSL as not applicable, while part 11844 is rated MSL 1 (unlimited). MSL 1 indicates the component has no moisture sensitivity restrictions and can be stored indefinitely without special humidity controls. This is a compliance advantage for 11844 and does not affect functional compatibility.
