Substitute Part Grouping Explanation

Substitution of the Molex 0791090014 is determined by strict equivalence across the following critical parameters:

  • Connector type (Receptacle)
  • Number of positions (30)
  • Pitch specification (0.079" / 2.00mm)
  • Row configuration (2 rows with 0.079" spacing)
  • Mounting method (Surface Mount)
  • Contact type (Female Socket)
  • Electrical ratings (1A, 125V)
  • Operating temperature range (-55°C ~ 125°C)
  • Insulation material (LCP, Glass Filled)
  • Flammability rating (UL94 V-0)

The Molex 0791091014 meets all these criteria and is therefore a direct functional equivalent. Both parts belong to the Milli-Grid 79109 series and maintain identical mechanical and electrical specifications.

Engineering Selection Recommendations

The Molex 0791091014 is the direct substitute for the obsolete 0791090014. Both connectors are mechanically and electrically identical across all critical parameters, ensuring pin-for-pin compatibility and functional equivalence in board-to-board or cable applications.

The primary distinction between the two parts is product status and regulatory compliance. The 0791091014 is currently in active production and carries ROHS3 compliance, whereas the 0791090014 is obsolete and RoHS non-compliant. The 0791091014 also features tin-plated posts compared to the tin-lead plating of the original part, aligning with modern lead-free manufacturing standards.

For new designs or ongoing production requiring this connector specification, the 0791091014 is the appropriate selection. The active product status ensures continued availability and supply chain support.

Frequently Asked Questions (FAQ)

Q: Are the 0791090014 and 0791091014 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 30 positions, 0.079" (2.00mm) pitch, 2-row configuration, surface mount mounting type, and insulation dimensions. They are pin-for-pin compatible.

Q: What is the difference between the contact finishes on the post?

A: The 0791090014 uses tin-lead plating on the posts, while the 0791091014 uses tin plating. Both maintain the same thickness (74.8µin / 1.90µm) and provide equivalent solder joint reliability. The tin plating on the 0791091014 reflects compliance with lead-free manufacturing standards.

Q: Can I use the 0791091014 in place of the 0791090014 in existing designs?

A: Yes. The 0791091014 is a direct functional equivalent. The mating contact finish (gold) and all electrical and mechanical parameters are identical, ensuring compatibility with existing PCB layouts and mating connectors.

Q: Why is the 0791090014 listed as obsolete?

A: The 0791090014 has been superseded by the 0791091014 in Molex's product line. The newer part offers improved regulatory compliance (ROHS3) and lead-free post plating while maintaining full functional equivalence.

Q: What is the packaging difference between these parts?

A: The 0791090014 packaging is not specified in the available data. The 0791091014 is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

Q: Are both parts suitable for automotive applications?
