Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC99J93FA is determined by strict equivalence across the following critical parameters:

• Frequency Performance: Maximum operating frequency of 180MHz
• Signal Interface: LVPECL differential input and output
• Functional Architecture: Single circuit with 2:5 input-to-output ratio, integrated PLL with bypass, and divider/multiplier capability
• Electrical Specifications: Supply voltage range 3.135V ~ 3.465V and operating temperature range -40°C ~ 85°C
• Physical Form Factor: 32-LQFP surface mount package (7x7mm)

The MPC99J93AC from Renesas Electronics Corporation satisfies all these parameters while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MPC99J93AC is the direct substitute for the obsolete MPC99J93FA. Both devices are electrically and mechanically equivalent across all functional parameters. The MPC99J93AC offers the following advantages:

• Active Product Status: Available for current and future production, eliminating supply chain risk associated with obsolete components
• Enhanced Compliance: ROHS3 compliant versus non-compliant status of the original part, meeting modern environmental and regulatory requirements
• Improved Availability: 2000 units in stock versus 1299 units for the obsolete part

The MPC99J93AC maintains identical electrical performance, signal interface specifications, and physical form factor, enabling direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the MPC99J93AC be used as a direct replacement for the MPC99J93FA?

A: Yes. Both devices share identical electrical specifications including 180MHz maximum frequency, LVPECL differential input/output, 2:5 input-to-output ratio, integrated PLL with bypass, and supply voltage range of 3.135V ~ 3.465V. The 32-LQFP surface mount package dimensions are equivalent (7x7mm).

Q: Are there package differences between these parts?

A: Both parts use 32-LQFP surface mount packages with 7x7mm dimensions. The supplier device package designation differs (32-LQFP versus 32-TQFP), but the physical form factor and pin configuration are compatible.

Q: What is the difference in Moisture Sensitivity Level (MSL)?

A: The MPC99J93FA has MSL 2 (1 Year storage), while the MPC99J93AC has MSL 3 (168 Hours storage). This affects component shelf life and handling requirements. MSL 3 requires more stringent moisture control during storage and prior to soldering.

Q: Does the RoHS compliance difference affect substitution?

A: The MPC99J93AC is ROHS3 compliant while the MPC99J93FA is non-compliant. For applications requiring RoHS compliance, the MPC99J93AC is the appropriate selection. For legacy systems without RoHS requirements, both parts are functionally equivalent.

Q: Are there any functional differences between the two devices?

A: No. Both devices provide identical clock driver functionality with PLL, bypass capability, divider/multiplier, and LVPECL signal interface. The MPC99J93AC includes dynamic clock switch capability as an additional feature.
