Frequently Asked Questions (FAQ)
Q: What makes the TE Connectivity 1-1775470-0 a valid substitute for the Molex 0554601072?
A: Both connectors share identical core specifications: 10 positions, 2.00mm mating pitch, surface mount technology, shrouded 4-wall design, solder termination, brass contacts with tin finish, and polyamide insulation. Both maintain UL94 V-0 and ROHS3 compliance. These aligned parameters establish functional equivalence for interconnection applications.
Q: Are there mechanical compatibility concerns when substituting these parts?
A: The connectors share identical pitch (2.00mm), position count (10), and shrouding configuration. Insulation height differs slightly (0.276" vs. 0.242"), which may affect mating stack height in constrained applications. PCB footprint compatibility should be verified against original design documentation.
Q: What is the significance of the product status difference?
A: The Molex part is classified as obsolete, indicating discontinued manufacturing and limited availability. The TE Connectivity substitute maintains active status with ongoing production and documented supply. This transition is necessary for long-term design support and component procurement.
Q: Do both parts meet the same regulatory requirements?
A: Yes. Both components are ROHS3 compliant and carry UL94 V-0 flammability certification, satisfying equivalent regulatory standards for industrial and consumer applications.
Q: What packaging format is available for the TE Connectivity substitute?
A: The TE Connectivity 1-1775470-0 is supplied in Tape & Reel (TR) packaging, standard for surface mount production environments.
