Selection of the 3-641238-5 is supported by:

• Complete parameter equivalence across all electrical specifications
• Identical mechanical configuration and mounting characteristics
• Matching contact finish and material specifications
• Equivalent RoHS3 compliance and moisture sensitivity rating
• Active product status ensuring ongoing availability and supply chain continuity

The substitute part is suitable for direct replacement in applications currently utilizing the 641238-5 without modification to circuit design, PCB layout, or mechanical assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can the 3-641238-5 be used as a direct replacement for the 641238-5?

A: Yes. The 3-641238-5 is electrically and mechanically equivalent to the 641238-5. All critical parameters including connector type, contact configuration, pitch, termination method, and compliance specifications are identical. Direct substitution is supported without design modification.

Q: What is the difference between 641238-5 and 3-641238-5?

A: The primary difference is product status. The 641238-5 is classified as obsolete, while the 3-641238-5 is an active product. The part numbers differ by a prefix designation (3-), but all functional and electrical specifications remain identical. The packaging differs: 641238-5 is listed with unspecified packaging, while 3-641238-5 is supplied in bulk packaging.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts conform to the MTA-100 series standard with identical pitch (0.100"), contact type (female socket), and IDC termination for 24 AWG wire. Mating connectors and cable assemblies designed for the 641238-5 are fully compatible with the 3-641238-5.

Q: Does the 3-641238-5 meet the same compliance requirements?

A: Yes. The 3-641238-5 maintains ROHS3 compliance and carries the same moisture sensitivity level (MSL 1 - Unlimited) as the original 641238-5. Both parts meet equivalent environmental and regulatory standards.

Q: Why should I select the 3-641238-5 over the obsolete 641238-5?

A: The 3-641238-5 is the recommended selection because it maintains active production status, ensuring reliable long-term availability and supply chain continuity. The obsolete 641238-5 may face procurement challenges and limited stock availability. Functionally, both parts are equivalent.

Q: What wire gauge does this connector support?

A: Both the 641238-5 and 3-641238-5 are rated for 24 AWG wire. The IDC termination method accommodates both discrete and ribbon cable configurations at this gauge.

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

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