Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 87577-2 with active alternatives is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (10 positions, 2 rows)
• Pitch spacing (0.100" / 2.54mm mating pitch and row spacing)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Detent Lock)

Electrical Performance Parameters:

• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A)
• Contact material (Phosphor Bronze)
• Insulation material (Thermoplastic)
• Material flammability rating (UL94 V-0)

Contact Interface Parameters:

• Contact length specifications (Mating: 0.318" / 8.08mm; Post: 0.135" / 3.43mm)
• Insulation height (0.400" / 10.16mm)
• Contact shape (Square)

The substitute part 5-103166-3 maintains full mechanical and electrical compatibility with the original 87577-2 across all critical parameters. Differences in contact finish specifications and product status do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-103166-3 is a direct functional equivalent to the obsolete 87577-2 rectangular connector header. Both components share identical mechanical dimensions, electrical ratings, and performance specifications across all critical parameters including pitch spacing, mounting configuration, contact geometry, and operating temperature range.

Product Status Advantage: The 5-103166-3 maintains active product status with significantly higher inventory availability (3200 units versus 722 units), ensuring long-term supply chain reliability for new production and field service applications.

Regulatory Compliance: The 5-103166-3 provides enhanced regulatory compliance with ROHS3 certification and REACH Unaffected status, compared to the 87577-2 which carries undefined compliance status. Both components maintain UL94 V-0 flammability rating and identical operating temperature specifications.

Contact Finish Considerations: The substitute part features gold-plated mating contacts (30.0µin thickness) compared to the original tin-lead finish (100.0µin thickness). Gold plating provides superior corrosion resistance and contact reliability in standard environmental conditions. The post termination on the substitute uses tin finish with identical thickness (100.0µin) to the original part, ensuring equivalent solder joint performance.

Packaging: The 5-103166-3 is supplied in tray packaging, which is standard for production environments and facilitates automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 5-103166-3 be used as a direct replacement for the 87577-2 in existing designs?
