Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66591-2 is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts must belong to the Multimate VI connector series
• Contact Configuration: Pin contact type with identical termination method (crimp)
• Electrical Rating: Wire gauge range of 18-22 AWG
• Material Specification: Brass base material with gold contact finish at 30.0µin thickness
• Construction Method: Stamped contact design
• Environmental Classification: Moisture Sensitivity Level 1 rating

The substitute part 66591-4 satisfies all these criteria, establishing it as a direct functional equivalent to the 66591-2 within the Multimate VI product family.

Parameter Comparison

Engineering Selection Recommendations

Both the 66591-2 and 66591-4 are functionally equivalent contacts within the Multimate VI series, sharing identical electrical and mechanical specifications for wire gauge, contact material, finish thickness, and termination method.

The primary distinction between these parts lies in regulatory compliance status. The 66591-4 carries ROHS3 compliance certification and REACH Unaffected status, whereas the 66591-2 is designated as RoHS non-compliant. Selection between these parts should be based on the specific regulatory requirements of the end application and target market. Applications requiring RoHS3 compliance or REACH compliance documentation necessitate use of the 66591-4. Applications without such regulatory constraints may utilize either part interchangeably from a functional standpoint.

Both parts maintain active production status and identical Moisture Sensitivity Level 1 classification, confirming their suitability for equivalent circuit assembly applications.

Frequently Asked Questions (FAQ)

Q: Can the 66591-4 be used as a direct replacement for the 66591-2 in existing assemblies?

A: Yes. The 66591-4 is functionally equivalent to the 66591-2 across all electrical and mechanical parameters, including wire gauge rating, contact material, finish specification, and termination method. Both are stamped pin contacts within the Multimate VI series rated for 18-22 AWG wire.

Q: What is the primary difference between these two part numbers?

A: The primary difference is regulatory compliance status. The 66591-4 is ROHS3 compliant with REACH Unaffected designation, while the 66591-2 is RoHS non-compliant. All other specifications are identical.

Q: Are there any packaging differences between the 66591-2 and 66591-4?

A: Both parts are supplied in bulk packaging. No packaging format differences exist between these parts.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 or REACH compliance, specify the 66591-4. For applications without such requirements, either part is functionally suitable.

Q: Do these contacts work with different wire gauges?

A: No. Both the 66591-2 and 66591-4 are rated exclusively for 18-22 AWG wire. They are not suitable for wire gauges outside this range.

Q: Is the gold plating thickness the same on both parts?

A: Yes. Both parts feature 30.0µin (0.76µm) gold contact finish thickness, ensuring identical electrical and corrosion resistance characteristics.

Q: Can these pin contacts be used in other TE Connectivity connector series?

A: These contacts are designed specifically for the Multimate VI series. Compatibility with other connector series is not established by the provided specifications.
