Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity 8-87589-5 qualifies as a direct substitute for the 3-87589-5 based on matching electrical and mechanical parameters. Substitution compatibility is determined by the following criteria:

Electrical Parameters:

• Identical connector type (Header), contact type (Male Pin), and current rating (3A)
• Matching pitch specifications: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Identical operating temperature range: -65°C ~ 105°C
• Same contact material (Phosphor Bronze) and insulation material (Polyamide, Nylon, Glass Filled)

Mechanical Parameters:

• Identical position count (8 positions in 2 rows)
• Matching shrouding configuration (Shrouded - 4 Wall)
• Identical mounting type (Through Hole) and termination method (Solder)
• Matching contact dimensions: 0.318" (8.08mm) mating length, 0.125" (3.18mm) post length, 0.533" (13.55mm) overall contact length
• Identical insulation height: 0.440" (11.18mm)

Series Compatibility:

• Both components belong to the AMPMODU Mod II series

The primary distinction between these parts is product status and contact finish specification, with the substitute part offering active availability and updated compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 8-87589-5 is the direct equivalent for the obsolete 3-87589-5 rectangular connector header. Both components maintain identical electrical and mechanical specifications, ensuring functional interchangeability in board-to-board and cable connector applications.

Product Status Consideration: The 8-87589-5 holds active product status with significantly higher inventory availability (12,850 pieces versus 849 pieces), providing supply chain continuity for new designs and ongoing production requirements.

Compliance Status: The substitute part 8-87589-5 is RoHS Compliant and carries REACH Unaffected status, compared to the main part's RoHS non-compliant designation. This compliance improvement aligns with current regulatory requirements for electronic components in regulated markets.

Contact Finish Specification: The primary technical distinction is the contact finish composition. The 8-87589-5 features pure Tin finish on both mating and post contacts, whereas the 3-87589-5 specifies Tin-Lead finish. Both finishes maintain identical thickness specifications (100.0µin / 2.54µm) and are compatible with standard solder reflow processes. The Tin finish of the substitute part reflects current industry standards and environmental compliance initiatives.

Series Continuity: Both components belong to the AMPMODU Mod II series, ensuring mechanical and electrical compatibility with existing connector systems and mating components designed for this series.

Frequently Asked Questions (FAQ)

Q: Are the 3-87589-5 and 8-87589-5 mechanically interchangeable?

A: Yes. Both components feature identical mechanical specifications including 8 positions in 2 rows, 0.100" (2.54mm) pitch spacing, shrouded 4-wall configuration, through-hole mounting, and matching contact dimensions. They are directly interchangeable in board-to-board and cable connector applications.

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

A: The 3-87589-5 uses Tin-Lead finish while the 8-87589-5 uses pure Tin finish. Both finishes are applied at identical thickness (100.0µin / 2.54µm) and are compatible with standard solder reflow processes. Tin finish represents current industry practice and environmental compliance standards.

Q: Can I use the 8-87589-5 as a replacement in existing designs using the 3-87589-5?
