Key Parameters

Substitute Part Grouping Explanation

The substitute part 66593-4 is classified as a direct manufacturer equivalent based on the following matching parameters:

• Contact Configuration: Both parts are stamped pin contacts within the Multimate VI series
• Electrical Specifications: Identical wire gauge rating (20-24 AWG), contact material (brass), and contact finish (gold plating at 30.0µin thickness)
• Termination Method: Both utilize crimp termination technology
• Environmental Rating: Identical Moisture Sensitivity Level (MSL 1 - Unlimited)
• Packaging Format: Both supplied in bulk packaging
• Base Product Number: Both derive from base product 66593

The primary distinction between 66593-2 and 66593-4 lies in regulatory compliance status and inventory availability, not in functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

66593-2 is suitable for applications where RoHS non-compliant components are acceptable and REACH-affected materials are permitted by design specifications or regulatory framework.

66593-4 is the appropriate selection for designs requiring RoHS compliance and REACH-unaffected material composition. This substitute part offers significantly higher inventory availability (20835 pieces versus 703 pieces), supporting production scalability and supply chain continuity.

Both parts maintain identical electrical and mechanical performance characteristics within the Multimate VI connector ecosystem. Selection between these parts should be determined by compliance requirements of the end application and supply chain availability needs.

Frequently Asked Questions (FAQ)

Q: Are 66593-2 and 66593-4 electrically interchangeable?

A: Yes. Both parts are stamped pin contacts with identical wire gauge ratings (20-24 AWG), contact material (brass), contact finish (gold at 30.0µin thickness), and termination method (crimp). Electrical performance and mating characteristics are equivalent.

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

A: The primary differences are regulatory compliance status and inventory availability. The 66593-4 is RoHS compliant and REACH unaffected, while the 66593-2 is RoHS non-compliant and REACH affected. The 66593-4 has substantially higher stock levels (20835 pieces versus 703 pieces).

Q: Can I substitute 66593-4 for 66593-2 in an existing design?

A: Substitution is permissible from an electrical and mechanical standpoint. However, design documentation and compliance requirements must be reviewed to confirm that RoHS compliance and REACH-unaffected material status are compatible with the application's regulatory framework.

Q: Are both parts supplied in the same packaging format?

A: Yes. Both 66593-2 and 66593-4 are supplied in bulk packaging, maintaining consistency in handling and integration processes.

Q: What does MSL 1 (Unlimited) mean for these contacts?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These contacts have unlimited shelf life under normal storage conditions and do not require special moisture-controlled storage or baking procedures prior to assembly.

Q: Do these parts have any export restrictions?

A: Both parts are classified under ECCN EAR99, which is the standard classification for most commercial electronic components. Specific export requirements depend on destination country and end-use application.
