Substitute Part Grouping Explanation

Substitution of the TE Connectivity 641220-6 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 3-641220-6 qualifies as a direct equivalent based on the following criteria:

Critical Matching Parameters:

• Connector type, contact type, and position count (6-position receptacle with female sockets)
• Pitch specification of 0.156" (3.96mm) and single-row configuration
• IDC cable termination method with 24 AWG wire gauge compatibility
• Gold contact finish with identical 30.0µin (0.76µm) thickness
• Closed-end design and locking ramp fastening mechanism
• MTA-156 series classification

The substitute part maintains complete functional and physical compatibility with the original component while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-641220-6 is the appropriate selection for applications currently specified with TE Connectivity 641220-6 connectors. The original part carries obsolete product status, limiting long-term procurement viability and technical support availability.

Compliance Advantages: The substitute part 3-641220-6 achieves RoHS compliance, whereas the original 641220-6 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements or customer specifications mandating compliant components.

Functional Equivalence: All electrical and mechanical parameters remain identical between the original and substitute parts. The connector maintains the same 6-position configuration, 0.156" pitch spacing, IDC termination method, 24 AWG wire gauge compatibility, and gold contact finish specifications. Physical dimensions, mounting characteristics, and fastening mechanisms are unchanged.

Inventory and Availability: The substitute part 3-641220-6 maintains active product status with 1119 pieces in stock, ensuring reliable procurement for new designs and replacement applications. The original obsolete part, while currently available with 1058 pieces in inventory, presents long-term supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can 3-641220-6 be used as a direct replacement for 641220-6 in existing designs?

A: Yes. The substitute part 3-641220-6 is electrically and mechanically equivalent to 641220-6. All connector specifications, including position count, pitch, contact type, termination method, and wire gauge compatibility, are identical. Direct substitution is appropriate for both new designs and retrofit applications.

Q: What is the significance of the product status difference between the two parts?

A: The original 641220-6 carries obsolete status, indicating discontinued production and limited future availability. The substitute 3-641220-6 maintains active product status, ensuring ongoing manufacturing support, consistent availability, and access to technical documentation. For long-term system reliability, the active substitute part is preferred.

Q: Does the RoHS compliance difference affect compatibility?

A: The RoHS compliance difference does not affect electrical or mechanical compatibility. However, applications subject to RoHS regulations or customer specifications requiring RoHS-compliant components must use 3-641220-6. The original 641220-6 is RoHS non-compliant and unsuitable for such applications.

Q: Are the packaging specifications different between these parts?

A: The original 641220-6 packaging specification is not provided in the technical data. The substitute 3-641220-6 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications before ordering.

Q: What wire gauges and cable types are compatible with these connectors?

A: Both connectors support 24 AWG wire gauge and accommodate discrete or ribbon cable types. IDC termination is the specified cable connection method for both parts.

Q: Is the contact finish specification identical between the two parts?

A: Yes. Both connectors feature gold contact finish with 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and corrosion resistance.

Q: Can these connectors be used with both discrete and ribbon cables?

A: Yes. Both the original 641220-6 and substitute 3-641220-6 support discrete or ribbon cable configurations with IDC termination.
