Key Parameters

Substitute Part Grouping Explanation

The substitute part 11850 qualifies as a direct equivalent based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

Critical Matching Parameters:

• Wire gauge specification: 18-20 AWG
• Terminal type: Circular ring configuration
• Stud size: #6 stud
• Termination method: Crimp connection
• Insulation material: Polyolefin with heat shrink
• Color designation: Red
• Mounting configuration: Free Hanging (In-Line)
• Brazed seam construction

Part 11850 maintains all specified electrical and mechanical characteristics of the original 11573, with the distinction that 11850 is currently active in production status and available in bulk packaging (50-piece packs).

Parameter Comparison

Engineering Selection Recommendations

Part 11850 is the direct functional equivalent for applications currently using 11573. Selection of 11850 is supported by:

Product Status: Part 11850 maintains active production status, ensuring continued availability and supply chain reliability compared to the obsolete 11573.

Compliance Certification: Part 11850 carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

Regulatory Alignment: Both parts maintain identical REACH unaffected status and EAR99 ECCN classification, confirming equivalent regulatory positioning.

Electrical and Mechanical Equivalence: All specified parameters for wire gauge, terminal configuration, stud size, termination method, insulation material, and construction features are identical between the two parts.

Packaging Consideration: Part 11850 is supplied in bulk 50-piece packaging, which may require adjustment to procurement and inventory management procedures compared to the original part's packaging specification.

Frequently Asked Questions (FAQ)

Q: Can part 11850 be used as a direct replacement for 11573 in existing applications?

A: Yes. Part 11850 is electrically and mechanically equivalent to 11573 across all specified parameters including wire gauge (18-20 AWG), terminal type (circular), stud size (#6), termination method (crimp), insulation material (polyolefin with heat shrink), and construction features (brazed seam).

Q: What is the primary difference between 11573 and 11850?

A: The primary difference is product status. Part 11573 is obsolete, while 11850 is active in production. Additionally, 11850 carries ROHS3 compliance certification and is supplied in bulk 50-piece packaging.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are specified identically for all electrical parameters including wire gauge range, insulation material, and contact configuration.

Q: Does the bulk packaging of 11850 affect its suitability as a substitute?

A: The bulk 50-piece packaging of 11850 does not affect electrical or mechanical suitability. Packaging format is a procurement and inventory consideration only and does not impact component performance or compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Part 11850 carries ROHS3 compliance certification. Part 11573, being obsolete, has not applicable RoHS status. Both maintain identical REACH unaffected status and EAR99 ECCN classification.

Q: What wire gauges are compatible with these terminals?

A: Both parts are specified for 18-20 AWG wire applications. Termination is accomplished through crimp connection with the #6 stud configuration.
