Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for socket contacts within the Multimate III+ series is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Contact type (Socket)
• Wire gauge range (26-30 AWG)
• Termination method (Crimp)
• Contact material (Brass)
• Contact finish (Gold)
• Contact finish thickness (30.0µin / 0.76µm)
• Manufacturing type (Stamped)
• Series designation (Multimate III+)

The substitute part 66394-8 and 66405-4 share identical electrical and mechanical characteristics across all critical parameters. The primary distinction between these parts is packaging format: 66394-8 is supplied in Cut Tape packaging, while 66405-4 is supplied in Bulk packaging. Both parts maintain active product status and full RoHS3 compliance. Packaging differences do not affect contact performance, electrical properties, or mechanical compatibility within the Multimate III+ connector system.

Parameter Comparison

Engineering Selection Recommendations

Both 66394-8 and 66405-4 are active products from TE Connectivity AMP Connectors with full electrical and mechanical equivalence for Multimate III+ socket contact applications. Selection between these parts is based on packaging requirements and supply chain considerations rather than functional performance.

66394-8 (Cut Tape Packaging): Suitable for applications requiring organized, tape-and-reel format delivery. Cut Tape packaging supports automated assembly processes and provides controlled component dispensing. This format is standard for high-volume production environments with pick-and-place equipment.

66405-4 (Bulk Packaging): Suitable for applications where packaging format flexibility is acceptable or where bulk quantities support manual assembly or kit preparation. Bulk packaging reduces per-unit packaging material and may support alternative inventory management strategies.

Both parts maintain RoHS3 compliance status and MSL 1 rating, confirming suitability for standard industrial and commercial applications without moisture sensitivity constraints. Selection should be based on production methodology, assembly equipment compatibility, and inventory management protocols rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Are 66394-8 and 66405-4 electrically identical?

A: Yes. Both parts are socket contacts with identical wire gauge (26-30 AWG), termination method (Crimp), contact material (Brass), contact finish (Gold), and finish thickness (30.0µin / 0.76µm). Electrical performance and contact resistance characteristics are equivalent.

Q: What is the only functional difference between these parts?

A: The primary difference is packaging format. 66394-8 is supplied in Cut Tape packaging, while 66405-4 is supplied in Bulk packaging. This distinction affects handling, dispensing, and inventory management but does not impact electrical or mechanical performance.

Q: Can 66394-8 and 66405-4 be used interchangeably in Multimate III+ assemblies?

A: Yes. Both parts are mechanically and electrically compatible within the Multimate III+ connector series. Interchangeability is determined by contact specifications, which are identical between the two parts.

Q: Which part should be selected for automated assembly?

A: 66394-8 in Cut Tape packaging is optimized for automated pick-and-place assembly processes. Cut Tape format provides organized component delivery compatible with standard assembly equipment.

Q: Which part should be selected for manual assembly or kit preparation?

A: 66405-4 in Bulk packaging supports flexible handling for manual assembly workflows and kit preparation applications where tape-and-reel format is not required.

Q: Are both parts RoHS compliant?

A: 66394-8 is explicitly RoHS3 compliant. 66405-4 has RoHS status listed as "Not applicable," which does not indicate non-compliance but rather that RoHS classification is not applicable to the bulk packaging format. Both parts meet equivalent environmental and regulatory standards.

Q: What is the MSL rating for both parts?

A: Both 66394-8 and 66405-4 have MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. These parts are suitable for standard storage and handling without specialized moisture control measures.

Q: Can packaging format be changed during procurement?

A: Packaging format is a fixed characteristic of each part number. 66394-8 is supplied exclusively in Cut Tape format, while 66405-4 is supplied exclusively in Bulk format. Selection of the appropriate part number ensures receipt of the required packaging format.
