Substitute Part Grouping Explanation

Substitution eligibility for the 8-520184-1 is determined by strict equivalence across the following critical parameters: tab width (0.250"), tab thickness (0.032"), wire gauge range (18-22 AWG), gender (female), termination method (crimp), insulation classification (fully insulated), overall length (0.855"), insulation diameter (0.135"), contact finish (tin), color (red), and mounting type (free hanging in-line).

The substitute parts 2-520184-2 and 2-520184-4 maintain full electrical and mechanical compatibility with the original 8-520184-1 across all specified parameters. Both substitutes are manufactured by TE Connectivity AMP Connectors within the Ultra-Fast series and share identical dimensional and functional characteristics. The primary distinction between substitutes relates to contact material composition and product status classification.

Engineering Selection Recommendations

For Active Product Status Requirement: Both 2-520184-2 and 2-520184-4 carry active product status, providing ongoing manufacturer support and supply chain continuity compared to the obsolete 8-520184-1.

For RoHS Compliance: All three parts maintain RoHS compliance. The main part carries ROHS3 designation, while both substitutes carry RoHS Compliant status. Both compliance levels satisfy regulatory requirements for electronic component applications.

For Moisture Sensitivity: All parts share MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

For Export Classification: All parts carry ECCN EAR99 classification and identical HTSUS code 8536.90.4000, ensuring consistent regulatory treatment across procurement and logistics.

Contact Material Consideration: Part 2-520184-2 maintains brass contact material identical to the original 8-520184-1. Part 2-520184-4 substitutes phosphor bronze contact material while maintaining all other electrical and mechanical specifications. Both contact materials are tin-finished and functionally equivalent within the specified wire gauge and application parameters.

Frequently Asked Questions (FAQ)

Q: Can 2-520184-2 and 2-520184-4 be used interchangeably with 8-520184-1?

A: Both substitute parts maintain full electrical and mechanical compatibility with 8-520184-1 across all critical parameters including tab dimensions, wire gauge range, insulation specifications, and mounting configuration. Direct substitution is supported.

Q: What is the difference between 2-520184-2 and 2-520184-4?

A: The primary difference is contact material composition. Part 2-520184-2 uses brass contact material, matching the original 8-520184-1. Part 2-520184-4 uses phosphor bronze contact material. Both materials are tin-finished and functionally equivalent for the specified 18-22 AWG wire gauge and crimp termination application.

Q: Why is 8-520184-1 listed as obsolete?

A: The 8-520184-1 carries obsolete product status. The active substitute parts 2-520184-2 and 2-520184-4 provide equivalent functionality with ongoing manufacturer support and supply availability.

Q: Are there packaging differences between these parts?

A: The main part 8-520184-1 does not specify packaging type. Both substitute parts 2-520184-2 and 2-520184-4 are supplied in bulk packaging. Inventory availability differs: 2-520184-2 has 1900 pieces in stock, while 2-520184-4 has 5400 pieces in stock.

Q: Do all three parts meet the same regulatory requirements?
