Parameter Comparison

Engineering Selection Recommendations

The Sullins Connector Solutions GWE82DHHN-T911 is the qualified substitute for the obsolete Molex 0877159303. Selection is based on:

• Functional Equivalence: All critical electrical and mechanical parameters match the original specification.
• Product Status: The substitute is an active product with current manufacturing support, eliminating supply chain risk associated with the obsolete Molex part.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with existing quality and environmental standards.
• Insulation Material Variation: The substitute uses Polyamide (PA9T) Nylon 9T insulation versus the original Polyamide (PA46) Nylon 4/6 Glass Filled. Both materials are polyamide-based with equivalent thermal and electrical performance for PCI Express applications.
• Packaging: The substitute is supplied in tray packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Sullins GWE82DHHN-T911 be used as a direct replacement for the Molex 0877159303?

A: Yes. The GWE82DHHN-T911 meets all critical substitution parameters including connector type, position count, pitch, card thickness, contact material, finish, and mounting configuration. The parts are electrically and mechanically equivalent for PCI Express applications.

Q: What is the difference in insulation material between the two parts?

A: The Molex part uses Polyamide (PA46) Nylon 4/6 with glass filler, while the Sullins part uses Polyamide (PA9T) Nylon 9T. Both are polyamide-based materials with equivalent thermal stability and electrical properties suitable for PCI Express card edge connector applications.

Q: Why is the Molex 0877159303 listed as obsolete?
