TE Connectivity 640606-8 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640606-8 is an 8-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a free-hanging, in-line mounting component with feed-through capability. The part is currently active in production with 899 units in stock.

Substitute parts are identified to address specific compliance requirements, packaging preferences, or inventory availability while maintaining functional equivalence within the MTA-156 connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640606-8 is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Both main and substitute parts must be 8-position receptacles
• Pitch & Spacing: 0.156" (3.96mm) pitch is mandatory for mechanical compatibility
• Contact Configuration: Female socket contacts required for mating compatibility
• Termination Method: IDC termination is the functional requirement
• Wire Gauge & Type: 22 AWG discrete or ribbon cable compatibility
• Mounting Style: Free-hanging, in-line configuration
• Contact Finish Thickness: 80.0µin (2.03µm) specification maintained
• Series Family: MTA-156 series designation

The substitute part 3-640606-8 meets all these criteria. The primary difference is the contact finish composition (tin versus tin-lead) and RoHS compliance status, which do not affect electrical or mechanical interchangeability within the specified parameter set.

Engineering Selection Recommendations

640606-8 (Tin-Lead Contact Finish)

Select this part number when:

• Legacy system designs require tin-lead contact finish specifications
• RoHS non-compliant applications are acceptable
• Existing inventory or supply chain commitments specify this exact part number

3-640606-8 (Tin Contact Finish)

Select this part number when:

• RoHS compliance is required for the end application or market
• Bulk packaging quantities align with procurement requirements
• Higher inventory availability is advantageous for supply chain planning

Both parts are active products from TE Connectivity and maintain full electrical and mechanical compatibility within the MTA-156 series specification. The selection between these two parts is determined by regulatory compliance requirements and contact finish specifications, not by functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are 640606-8 and 3-640606-8 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 8-position receptacle configuration, 0.156" (3.96mm) pitch, free-hanging in-line mounting, and feed-through design. They mate with the same plug connectors and accept the same 22 AWG cable types.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 640606-8 features tin-lead contact finish while the 3-640606-8 features tin contact finish. Both maintain the same 80.0µin (2.03µm) thickness specification. The primary distinction is RoHS compliance status: tin-lead is RoHS non-compliant, while tin is RoHS compliant.

Q: Can I use 3-640606-8 as a direct replacement for 640606-8?

A: Electrical and mechanical compatibility is confirmed. The decision to substitute depends on whether RoHS compliance is required for your application. If RoHS compliance is not a requirement, either part functions identically. If RoHS compliance is mandated, 3-640606-8 is the appropriate selection.

Q: Does packaging type affect connector performance?

A: No. The 640606-8 is supplied in standard packaging while 3-640606-8 is supplied in bulk packaging. Packaging type does not affect electrical performance, mechanical fit, or contact reliability. Packaging selection is based on procurement quantity requirements and inventory management preferences.

Q: Are both parts currently in production?

A: Yes. Both 640606-8 and 3-640606-8 are classified as active products. Current inventory levels are 899 units for 640606-8 and 1431 units for 3-640606-8.

Q: What wire gauges are compatible with these connectors?

A: Both connectors are specified for 22 AWG wire gauge and accept discrete or ribbon cable types. IDC termination is the required connection method.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
