Parameter Comparison

Engineering Selection Recommendations

The 2-640456-4 is a direct functional equivalent to the obsolete 2-641215-4. Both components are manufactured by TE Connectivity within the MTA-100 series and maintain identical electrical and mechanical specifications across all critical parameters.

Compliance Status: Both parts are ROHS3 compliant and carry UL94 V-0 material flammability ratings, meeting current regulatory requirements. The substitute part 2-640456-4 maintains active product status, ensuring ongoing availability and supply chain continuity.

Contact Finish Consideration: The primary specification difference is the contact finish on the mating surface. The main part features gold plating, while the substitute features tin plating. Both finishes are suitable for general-purpose applications and do not affect electrical performance or mechanical compatibility in standard operating conditions.

Packaging: The substitute part is supplied in bulk packaging, which may differ from the original part's packaging configuration. This does not affect component functionality or interchangeability.

Frequently Asked Questions (FAQ)

Q: Can 2-640456-4 be used as a direct replacement for 2-641215-4?

A: Yes. The 2-640456-4 maintains identical electrical and mechanical specifications across all critical parameters including pitch, position count, voltage rating, operating temperature range, mounting type, and termination method. Both components are part of the MTA-100 series and are fully compatible.

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

A: The main part 2-641215-4 features gold-plated mating contacts, while the substitute 2-640456-4 features tin-plated mating contacts. Both finishes provide adequate corrosion resistance and electrical conductivity for general-purpose applications. The choice between finishes depends on specific application requirements and environmental conditions.

Q: Why is the main part listed as obsolete?

A: The 2-641215-4 is classified as obsolete, indicating it is no longer in active production. The 2-640456-4 serves as the current active equivalent within the MTA-100 series, ensuring continued availability for new designs and replacement applications.

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

A: No. Both parts are ROHS3 compliant, carry UL94 V-0 material flammability ratings, and maintain identical moisture sensitivity levels. Regulatory compliance is equivalent across both components.

Q: Does packaging affect interchangeability?

A: No. The substitute part is supplied in bulk packaging, which is a logistical consideration only. The physical connector specifications and electrical performance remain identical regardless of packaging configuration.

Q: What applications are these connectors suitable for?

A: Both parts are designated for general-purpose applications. The 24-position, 0.100" pitch configuration with through-hole solder termination makes these connectors suitable for board-to-cable/wire interconnections in standard electronic assemblies.
