Engineering Selection Recommendations
The Molex 2128254001 is the qualified substitute for the 0787301002. Both parts are manufactured by Molex and share identical electrical and mechanical specifications for all critical parameters: 288-position DIMM configuration, DDR4 SDRAM compatibility, surface mount technology, and gold contact finish at 30.0µin thickness.
The primary distinction is product status: the 0787301002 is Last Time Buy, while the 2128254001 is Active. This transition from discontinued to active production status makes the 2128254001 the appropriate selection for new designs and ongoing production requirements.
Both parts comply with ROHS3 standards and carry MSL rating of 1, ensuring compatibility with standard manufacturing and storage conditions.
Frequently Asked Questions (FAQ)
Q: Can the Molex 2128254001 be used as a direct replacement for the 0787301002?
A: Yes. Both parts meet identical specifications for connector style, position count, memory type, mounting configuration, and contact characteristics. The 2128254001 is the active production equivalent.
Q: What is the significance of the Last Time Buy status on the 0787301002?
A: Last Time Buy indicates the manufacturer has discontinued production. The 0787301002 remains available from existing inventory but will not be replenished. The 2128254001 provides continuity for future procurement.
Q: Are there any mechanical compatibility concerns when substituting these parts?
A: No. Both parts feature identical mounting types, mounting features, and board lock/latch configurations. PCB layout and assembly processes remain unchanged.
Q: What is the importance of the 30.0µin gold contact finish thickness specification?
A: Contact finish thickness directly affects electrical performance, corrosion resistance, and long-term reliability. Both parts maintain this specification, ensuring equivalent signal integrity and service life.
Q: Does the MSL rating of 1 affect handling or storage procedures?
A: MSL 1 indicates unlimited moisture sensitivity. Both parts require standard handling practices with no special moisture control measures during storage or assembly.
Q: Are there differences in packaging between these parts?
A: The 0787301002 is specified as Tray packaging. The 2128254001 packaging is not specified in available data. Verify packaging requirements with the supplier for your specific procurement needs.
