- Regulatory Compliance: Both parts are ROHS3 compliant and classified as EAR99, meeting current environmental and export requirements
- Production Status: The substitute is in active production with confirmed inventory availability (19,591 pcs), ensuring long-term supply chain reliability compared to the obsolete original part
- Termination Compatibility: Solder termination method is identical, requiring no assembly process modification
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 284512-2 be used as a direct replacement for the Molex 0393550002 on existing PCBs?
A: Yes. Both parts share identical pitch (4.60mm), position count (2), orientation (90° right-angle), and shrouded male pin configuration. PCB footprints and mounting holes are compatible. No layout modifications are required.
Q: Are there electrical rating differences between these parts?
A: The TE Connectivity 284512-2 has a slightly higher current rating (11A vs. 10A at UL). Voltage rating remains 300V for both. The substitute meets or exceeds the original part's electrical specifications.
Q: What is the difference in operating temperature range?
A: The Molex 0393550002 operates to 140°C maximum. The TE Connectivity 284512-2 operates from -40°C to 110°C. For applications requiring sustained operation above 110°C, the original Molex specification must be verified against actual system requirements.
Q: Are both parts RoHS compliant?
A: Yes. Both the Molex 0393550002 and TE Connectivity 284512-2 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
Q: What is the packaging difference?
A: The Molex part is supplied in standard packaging (not specified). The TE Connectivity 284512-2 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
Q: Can I use the TE Connectivity part in new designs?
A: Yes. The TE Connectivity 284512-2 is in active production status with confirmed inventory. It is suitable for both replacement applications and new design implementations requiring 2-position, 4.6mm pitch terminal block headers with 90° right-angle through-hole mounting.
