Substitute Part Grouping Explanation

Substitution eligibility for the ATF750C-15JC is determined by the following critical parameters:

• Base Product Number: Must be ATF750 to ensure core architectural compatibility
• Series: Must be ATF750C(L) to maintain functional equivalence
• Programmable Type: Must be EE PLD to preserve programming methodology
• Number of Macrocells: Must be 10 to match logic capacity
• Number of I/O: Must be 10 to ensure pin-count compatibility
• Package / Case: Must be 28-LCC (J-Lead) for mechanical fit
• Supplier Device Package: Must be 28-PLCC (11.51x11.51) for PCB footprint compatibility
• Mounting Type: Must be Surface Mount for assembly process alignment

The ATF750C-10JU meets all substitution criteria while offering improved electrical performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The ATF750C-10JU is a direct functional substitute for the ATF750C-15JC based on matching core architectural parameters: identical macrocell count, I/O configuration, package geometry, and programmable logic type.

The ATF750C-10JU offers the following advantages:

• Active Product Status: Currently manufactured and supported by Microchip Technology, ensuring long-term availability and supply chain stability
• RoHS3 Compliance: Meets current environmental and regulatory requirements, whereas the main part is RoHS non-compliant
• Extended Operating Temperature Range: -40°C to 85°C versus 0°C to 70°C, providing broader thermal application scope
• Improved Timing Performance: 10 ns maximum propagation delay versus 15 ns, delivering faster logic operation
• Wider Voltage Supply Tolerance: 4.5V to 5.5V versus 4.75V to 5.25V, offering greater power supply margin

Selection of the ATF750C-10JU is appropriate for applications requiring compliance with modern regulatory standards and extended operational parameters.

Frequently Asked Questions (FAQ)

Q: Can the ATF750C-10JU directly replace the ATF750C-15JC in existing designs?

A: Yes. Both devices share identical macrocell count (10), I/O pin count (10), package type (28-LCC J-Lead), and physical footprint (28-PLCC 11.51x11.51mm). The ATF750C-10JU is electrically compatible and functionally equivalent for all applications where the ATF750C-15JC was originally specified.

Q: What is the significance of the timing difference between these parts?

A: The ATF750C-15JC has a maximum propagation delay of 15 ns, while the ATF750C-10JU has a maximum of 10 ns. The substitute part delivers faster logic operation. Applications with timing-critical requirements benefit from the improved performance of the ATF750C-10JU.

Q: Are there packaging or mounting differences?

A: No. Both parts use identical surface mount packaging: 28-LCC (J-Lead) with a 28-PLCC footprint measuring 11.51x11.51mm. PCB layout and assembly processes require no modification.

Q: Why is the main part listed as obsolete?

A: The ATF750C-15JC is classified as obsolete by Microchip Technology. The ATF750C-10JU remains in active production, making it the recommended choice for new designs and ongoing system support.

Q: What are the compliance differences?

A: The ATF750C-15JC is RoHS non-compliant, while the ATF750C-10JU is ROHS3 compliant. For applications subject to environmental regulations or customer requirements mandating RoHS compliance, the ATF750C-10JU is the appropriate selection.

Q: How do the operating temperature ranges differ?

A: The ATF750C-15JC operates from 0°C to 70°C, while the ATF750C-10JU operates from -40°C to 85°C. The substitute part supports a wider temperature range, suitable for industrial and extended-temperature applications.
