MPC9992FA Clock Generator Equivalent & Substitute Parts

Part Overview

The MPC9992FA is a Clock Generator, Fanout Distribution, and Multiplexer IC manufactured by NXP Semiconductors. This 32-LQFP surface mount device operates at a maximum frequency of 400MHz with integrated Phase-Locked Loop (PLL) and bypass capability. The device accepts PECL and Crystal inputs and provides PECL outputs with a 2:7 input-to-output ratio and differential signaling on both input and output paths.

The MPC9992FA is classified as obsolete. Locating equivalent or substitute parts is necessary to support legacy system maintenance, board-level repairs, and production continuity for applications still utilizing this clock distribution architecture.

Substitute Part Grouping Explanation

Substitution eligibility for the MPC9992FA is determined by strict equivalence across the following critical parameters:

• Package / Case: 32-LQFP (7x7) form factor
• Frequency - Max: 400MHz operational capability
• Input Type: PECL and Crystal input support
• Output Type: PECL output configuration
• Ratio - Input:Output: 2:7 multiplexing ratio
• Differential - Input:Output: Yes/Yes differential signaling
• PLL with Bypass: Integrated PLL with bypass mode
• Number of Circuits: Single circuit configuration
• Voltage - Supply: 3.135V ~ 3.465V supply range
• Operating Temperature: 0°C ~ 70°C temperature range

The MPC9992AC qualifies as a direct substitute based on identical electrical specifications, functional architecture, and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The MPC9992AC is a direct functional and mechanical equivalent to the MPC9992FA. Both devices share identical electrical specifications, package geometry, and operational characteristics across all critical parameters.

The MPC9992AC offers improved regulatory compliance: it is ROHS3 compliant, whereas the MPC9992FA is RoHS non-compliant. This distinction is significant for applications subject to environmental or procurement regulations requiring RoHS compliance.

Both parts are classified as obsolete. The MPC9992AC has a Moisture Sensitivity Level (MSL) rating of 3 (168 Hours), compared to the MPC9992FA's MSL rating of 2 (1 Year). This indicates different moisture handling and storage requirements; the MPC9992AC requires more stringent moisture control during storage and handling.

Selection between these parts should be based on regulatory requirements, inventory availability, and moisture management capabilities within the production environment.

Frequently Asked Questions (FAQ)

Q: Can the MPC9992AC be used as a direct replacement for the MPC9992FA in existing designs?

A: Yes. The MPC9992AC is electrically and mechanically equivalent to the MPC9992FA. All critical parameters—frequency, input/output types, differential signaling, supply voltage, operating temperature range, and package geometry—are identical. No circuit modifications are required.

Q: What is the difference in RoHS compliance between these parts?

A: The MPC9992FA is RoHS non-compliant. The MPC9992AC is ROHS3 compliant. If your application or procurement requirements mandate RoHS compliance, the MPC9992AC is the appropriate selection.

Q: Why do these parts have different Moisture Sensitivity Level (MSL) ratings?

A: The MPC9992FA has an MSL rating of 2 (1 Year), while the MPC9992AC has an MSL rating of 3 (168 Hours). MSL ratings define the maximum time a component can be exposed to moisture at specified temperature and humidity conditions before soldering. The MPC9992AC requires more careful moisture control during storage and handling. Ensure your production environment and storage protocols support the MSL 3 requirement.

Q: Are both parts still in production?

A: No. Both the MPC9992FA and MPC9992AC are classified as obsolete. Availability is limited to existing inventory from authorized distributors.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence in package type (32-LQFP), maximum frequency (400MHz), input/output signal types (PECL/Crystal input, PECL output), input-to-output ratio (2:7), differential signaling capability (Yes/Yes), PLL with bypass functionality, supply voltage range (3.135V ~ 3.465V), and operating temperature range (0°C ~ 70°C).

Q: Can I use a different package variant of the MPC99 series as a substitute?

A: No. Substitution is limited to parts with identical package geometry (32-LQFP, 7x7 form factor). Different package types are not interchangeable without circuit board redesign.
