Substitute Part Grouping Explanation

Substitution of the TE Connectivity 641238-8 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Electrical Specifications: 8-position, 0.100" (2.54mm) pitch, single-row configuration
• Termination Method: IDC termination compatible with 24 AWG wire
• Physical Characteristics: Closed-end design, white color, gold contact finish at 30.0µin thickness
• Series Designation: MTA-100 series compatibility
• Mounting Configuration: Free hanging (in-line) and right-angle mounting support

The substitute part 3-641238-8 maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 3-641238-8 serves as the direct functional equivalent to the obsolete 641238-8 model. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and interchangeability in existing circuit designs.

Product Status Consideration: The 641238-8 is classified as obsolete, while the 3-641238-8 maintains active product status. This distinction is significant for long-term supply chain planning and future design iterations.

Compliance Advantage: The 3-641238-8 provides ROHS3 compliance certification and REACH unaffected status, whereas the original part lists compliance as not applicable and vendor undefined. For applications subject to environmental regulations or procurement standards requiring documented compliance, the substitute part offers superior documentation and regulatory alignment.

Packaging & Availability: Both parts are available in new original condition with comparable inventory levels. The substitute is supplied in bulk packaging, which may influence procurement logistics and cost structure depending on application volume requirements.

Electrical & Mechanical Equivalence: No deviations exist in connector type, contact configuration, pitch, termination method, wire gauge compatibility, contact finish specifications, or mounting characteristics. Direct substitution is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Are the 641238-8 and 3-641238-8 pin-for-pin compatible?

A: Yes. Both components are 8-position receptacles with identical pitch (0.100"), contact type (female socket), and mounting configurations. They are electrically and mechanically interchangeable.

Q: What is the significance of the product status difference?

A: The 641238-8 is obsolete, indicating TE Connectivity no longer manufactures or supports this part number. The 3-641238-8 is active, ensuring continued availability, technical support, and compliance with current manufacturing standards.

Q: Can I use the 3-641238-8 as a direct replacement in existing designs?

A: Yes. The substitute part maintains all critical specifications: 8-position configuration, 0.100" pitch, IDC termination for 24 AWG wire, gold contact finish, and closed-end design. No design modifications are required.

Q: What is the difference in compliance certifications?

A: The original 641238-8 lists compliance as not applicable and vendor undefined. The 3-641238-8 provides explicit ROHS3 compliance and REACH unaffected status, offering documented regulatory alignment for applications requiring environmental compliance verification.

Q: Are there packaging differences between these parts?

A: The 641238-8 packaging is not specified in available documentation. The 3-641238-8 is supplied in bulk packaging. Packaging format may influence procurement quantities and storage requirements but does not affect electrical or mechanical performance.

Q: What wire gauges are supported by both connectors?

A: Both the 641238-8 and 3-641238-8 support 24 AWG wire with IDC termination. They accommodate both discrete and ribbon cable configurations.

Q: Is the contact finish specification identical?

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

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
