Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 66601-8 are identified based on strict compatibility criteria within the Multimate III+ connector series. The following parameters must remain constant for substitution eligibility:

• Series designation (Multimate III+)
• Contact type (Stamped socket)
• Wire gauge range (14-18 AWG)
• Contact termination method (Crimp)
• Base contact material (Brass)
• Connector category (Contacts)
• Packaging format (Bulk)

The 66601-1 qualifies as a direct substitute because it maintains all critical interface parameters. The primary difference is the contact finish specification: 66601-8 features gold plating at 30.0µin thickness, while 66601-1 features tin-lead plating at 50.0µin thickness. Both finishes provide equivalent electrical conductivity and mechanical retention within the Multimate III+ socket interface.

Parameter Comparison

Engineering Selection Recommendations

Both 66601-8 and 66601-1 are Active product status components suitable for new designs and ongoing production applications. The selection between these parts depends on specific compliance and material requirements:

66601-8 (Gold Finish): This part is RoHS Compliant and recommended for applications requiring adherence to RoHS Directive 2011/65/EU. The gold plating provides superior corrosion resistance and is preferred in high-reliability applications and environments with potential exposure to corrosive elements.

66601-1 (Tin-Lead Finish): This part is marked as REACH Affected and Not applicable for RoHS status. It is suitable for applications where RoHS compliance is not a requirement and where tin-lead plating specifications are acceptable. The thicker plating layer (50.0µin versus 30.0µin) provides additional material reserve.

Both contacts maintain identical electrical and mechanical interface specifications within the Multimate III+ series, ensuring direct interchangeability at the connector interface level. Selection should be based on regulatory compliance requirements and environmental exposure conditions specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can 66601-1 be used as a direct replacement for 66601-8 in existing assemblies?

A: Yes. Both parts are socket contacts for the Multimate III+ series with identical wire gauge (14-18 AWG), termination method (crimp), and mechanical interface specifications. The primary difference is the contact finish material and thickness. Substitution is mechanically and electrically valid.

Q: What is the significance of the contact finish difference between these parts?

A: The 66601-8 features gold plating (30.0µin), which provides superior corrosion resistance and is required for RoHS-compliant applications. The 66601-1 features tin-lead plating (50.0µin), which is thicker but does not meet RoHS requirements. Both finishes provide adequate electrical conductivity for the specified wire gauge range.

Q: Are there any environmental or regulatory constraints that would prevent substitution?

A: Yes. The 66601-8 is RoHS Compliant, while 66601-1 is Not applicable for RoHS status and is REACH Affected. Applications subject to RoHS Directive 2011/65/EU must use 66601-8. Applications without RoHS requirements may use either part.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both 66601-8 and 66601-1 are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling or storage requirements during manufacturing and assembly.

Q: What is the base product number relationship between these parts?

A: Both 66601-8 and 66601-1 share the base product number 66601. The suffix designates the specific contact finish variant. This nomenclature indicates they are part of the same contact family within the Multimate III+ series.

Q: Are there inventory considerations when selecting between these substitute parts?

A: Inventory levels differ between the two parts. The 66601-8 has 737 pieces in stock, while 66601-1 has 21,388 pieces in stock. Availability may influence selection for time-sensitive procurement scenarios.
