Substitute Part Grouping Explanation

Substitution of the TE Connectivity 641237-8 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters:

• Contact type (Female Socket)
• Number of positions (8)
• Wire gauge compatibility (22 AWG)
• Contact finish and thickness (Gold, 30.0µin)

Mechanical Parameters:

• Connector pitch (0.100" / 2.54mm)
• Number of rows (1)
• Mounting configuration (Free Hanging, Right Angle)
• Fastening type (Locking Ramp)
• Cable termination method (IDC)
• Closed-end design

Series Compatibility:

• MTA-100 series designation

The substitute part 3-641237-8 meets all these criteria and represents the direct equivalent with active product status.

Engineering Selection Recommendations

The TE Connectivity 3-641237-8 is the direct functional equivalent of the obsolete 641237-8 model. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with TE Connectivity, ensuring continued availability, manufacturing support, and supply chain reliability. The obsolete status of the original part necessitates transition to the active equivalent.

Regulatory Compliance: The substitute part 3-641237-8 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for electronic components. This compliance status supports integration into modern manufacturing processes and end-market applications subject to RoHS directives.

Electrical and Mechanical Equivalence: All electrical parameters, mechanical dimensions, contact specifications, and termination methods are identical between the main part and substitute. This equivalence ensures direct interchangeability without circuit redesign or mechanical modification.

Packaging Consideration: The substitute part is supplied in bulk packaging, which may differ from the original part's packaging specification. Bulk packaging does not affect component functionality or electrical performance but may influence procurement and inventory management workflows.

Frequently Asked Questions (FAQ)

Q: Can the 3-641237-8 be used as a direct replacement for the 641237-8 in existing designs?

A: Yes. The 3-641237-8 is electrically and mechanically identical to the 641237-8 across all specified parameters. Direct substitution is supported without design modification.

Q: What is the difference between the 641237-8 and 3-641237-8 part numbers?

A: The primary difference is product status. The 641237-8 is obsolete, while the 3-641237-8 is active. The "3-" prefix in the substitute part number indicates a variant designation within the TE Connectivity MTA-100 series. All functional specifications remain identical.

Q: Does the bulk packaging of the 3-641237-8 affect its performance or compatibility?

A: No. Packaging type does not affect electrical performance, mechanical fit, or functional compatibility. Bulk packaging is a supply and handling specification only.

Q: Are there any compliance differences between the two parts?

A: The substitute part 3-641237-8 carries ROHS3 compliance certification. The original part lists RoHS status as not applicable. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications.

Q: What wire gauges and cable types are compatible with this connector?

A: The connector is rated for 22 AWG wire and supports both discrete and ribbon cable termination via IDC (Insulation Displacement Contact) method.

Q: Is the gold contact finish specification identical between both parts?

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

Q: What is the pitch specification for this connector?

A: The connector pitch is 0.100 inches (2.54 millimeters), which is the standard spacing for MTA-100 series rectangular connectors.

Q: Can this connector be used in both in-line and right-angle mounting configurations?

A: Yes. The connector supports both free-hanging in-line and right-angle mounting types, providing flexibility for various PCB and cable assembly orientations.
