Engineering Selection Recommendations

The MPC9993AC from Renesas Electronics Corporation is the qualified substitute for the obsolete MPC9993FA. Selection of the MPC9993AC is based on the following engineering factors:

Product Status: The MPC9993FA is obsolete, while the MPC9993AC maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The MPC9993AC is ROHS3 compliant, meeting current environmental and regulatory requirements. The original MPC9993FA is RoHS non-compliant, making the substitute preferable for new designs and applications subject to RoHS directives.

Electrical Equivalence: All critical electrical parameters are identical between the two devices, including frequency rating, signal types, supply voltage, and operating temperature range. The devices are functionally interchangeable at the circuit level.

Mechanical Compatibility: Both devices utilize the 32-LQFP package format with identical pinout and footprint, enabling direct board-level substitution without PCB redesign.

Moisture Sensitivity Consideration: The MPC9993AC has an MSL rating of 3 (168 hours) compared to the MPC9993FA's MSL rating of 2 (1 year). This difference requires attention to storage and handling procedures during manufacturing and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the MPC9993AC be used as a direct replacement for the MPC9993FA in existing designs?

A: Yes. The MPC9993AC provides electrical and mechanical equivalence to the MPC9993FA. All critical parameters including frequency, signal types, supply voltage, operating temperature, and package format are identical. Direct substitution is possible without circuit modification.

Q: What is the significance of the different MSL ratings between the two parts?

A: The MPC9993FA has an MSL rating of 2 (1 year floor life), while the MPC9993AC has an MSL rating of 3 (168 hours floor life). This means the MPC9993AC has a shorter allowable exposure time to moisture after reflow soldering. Manufacturing and assembly processes must account for this shorter floor life window to prevent moisture-related failures.

Q: Are there any differences in pinout or package footprint between these devices?

A: No. Both the MPC9993FA and MPC9993AC use the 32-LQFP package with identical pinout and footprint dimensions. PCB layout and component placement require no modification for substitution.

Q: Why is the MPC9993AC preferred over the MPC9993FA for new designs?

A: The MPC9993AC is preferred because it maintains active production status, ensuring availability for current and future production runs. Additionally, ROHS3 compliance of the MPC9993AC aligns with current environmental regulations and customer requirements, whereas the MPC9993FA's RoHS non-compliant status limits its use in regulated applications.

Q: Are the electrical performance characteristics identical between these two clock driver ICs?

A: Yes. Both devices operate at 200MHz maximum frequency with LVPECL differential input and output signaling. The 2:5 input-to-output ratio, PLL with bypass configuration, supply voltage range, and operating temperature specifications are identical.

Q: What should be considered when transitioning from MPC9993FA to MPC9993AC in production?

A: The primary consideration is the MSL rating difference. The MPC9993AC requires stricter moisture control during storage and assembly. Verify that manufacturing processes comply with the 168-hour floor life requirement. All other electrical and mechanical parameters are equivalent, requiring no design or circuit changes.
