Engineering Selection Recommendations

The TE Connectivity 6-87579-0 serves as the direct functional equivalent to the obsolete 1-87579-0 part number. Both components maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, pitch spacing, mounting orientation, and thermal operating range.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 1-87579-0 is designated obsolete and carries RoHS non-compliant status, reflecting its Tin-Lead contact finish composition. The 6-87579-0 maintains active product status with RoHS compliance certification, incorporating a Tin contact finish that aligns with current environmental and regulatory requirements.

For applications requiring new component procurement, design updates, or long-term supply chain continuity, the 6-87579-0 is the appropriate selection. The contact finish modification from Tin-Lead to Tin does not alter mating performance, electrical conductivity, or mechanical compatibility with existing connector receptacles designed for the AMPMODU Mod II series.

Packaging format differs between the two parts (bulk versus tray), which affects handling and inventory management but does not impact functional performance or component specifications.

Frequently Asked Questions (FAQ)

Q: Are the 1-87579-0 and 6-87579-0 connectors mechanically interchangeable?

A: Yes. Both parts maintain identical mechanical specifications including connector type, position count, pitch spacing, mounting configuration, shrouding design, and contact geometry. They are fully interchangeable in applications designed for the AMPMODU Mod II 26-position header series.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: The 1-87579-0 features Tin-Lead contact plating, while the 6-87579-0 uses Tin plating. Both finishes provide equivalent electrical conductivity and mating performance.
