Z84C2010FEC Equivalent & Substitute Parts

Part Overview

The Z84C2010FEC is a specialized I/O controller interface component manufactured by Zilog, part of the Z80 series. This 44-QFP surface mount device functions as an I/O controller interface for legacy computing and embedded systems applications. The main part is classified as obsolete, making identification of functionally equivalent substitute parts essential for system maintenance, repair, and component sourcing in production environments where Z80-based systems remain in operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Z84C2010FEC is determined by the following criteria:

• Manufacturer & Series: Must be Zilog Z80 series to ensure functional compatibility with Z80-based system architectures
• Base Product Number: Z84C20 designation ensures core I/O controller functionality remains consistent
• Application: I/O Controller interface function must be preserved
• Mounting Type: Surface mount technology must be maintained for PCB compatibility
• Package Type: Acceptable package variants include QFP and LQFP configurations, both standard for this component class

The Z84C2010AEG qualifies as a direct substitute based on these parameters. While package designation differs (44-LQFP versus 44-QFP), both are surface mount packages with identical pin counts and compatible footprints for this component category.

Parameter Comparison

Engineering Selection Recommendations

Z84C2010AEG is the qualified substitute for Z84C2010FEC based on the following factors:

• Functional Equivalence: Both components share the Z80 series architecture and I/O controller interface designation, ensuring compatibility with existing Z80-based system designs
• Package Compatibility: The 44-LQFP package maintains the same pin count and surface mount footprint as the 44-QFP, allowing direct PCB substitution
• Product Status Advantage: Z84C2010AEG holds Last Time Buy status, providing extended availability compared to the obsolete Z84C2010FEC
• Compliance Improvement: Z84C2010AEG achieves ROHS3 compliance, offering environmental and regulatory advantages for new production runs or system updates
• Moisture Sensitivity Parity: Identical MSL rating (3, 168 Hours) ensures equivalent handling and storage requirements

Selection between these parts should be based on inventory availability, compliance requirements for the target application, and production timeline constraints.

Frequently Asked Questions (FAQ)

Q: Can Z84C2010AEG be used as a direct replacement for Z84C2010FEC on existing PCBs?

A: Yes. Both components are 44-pin surface mount packages with compatible footprints. The QFP and LQFP package variants maintain identical pin assignments and spacing for this component class, allowing direct substitution on existing circuit boards.

Q: What is the difference between 44-QFP and 44-LQFP packages?

A: QFP (Quad Flat Package) and LQFP (Low-profile Quad Flat Package) are both surface mount package types with 44 pins. LQFP features a lower profile than standard QFP. For the Z84C20 series, both package types are functionally equivalent and maintain compatible PCB footprints.

Q: Why is Z84C2010FEC classified as obsolete?

A: Z84C2010FEC has reached end-of-life status with Zilog. The Z84C2010AEG, designated as Last Time Buy, represents the final production variant available from the manufacturer before complete discontinuation of this product line.

Q: Are there any compliance differences between the two parts?

A: Yes. Z84C2010FEC is RoHS non-compliant, while Z84C2010AEG achieves ROHS3 compliance. Both maintain REACH Unaffected status. For applications requiring RoHS compliance, Z84C2010AEG is the appropriate selection.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both Z84C2010FEC and Z84C2010AEG carry MSL rating 3 (168 Hours), requiring identical handling, storage, and reflow procedures during assembly and repair operations.

Q: Which part should be selected for new production designs?

A: Z84C2010AEG is the recommended selection for new production due to Last Time Buy availability status, ROHS3 compliance, and extended component lifecycle compared to the obsolete Z84C2010FEC.
