Substitute Part Grouping Explanation

Substitution of the ATF750C-7JC is determined by strict equivalence across the following critical parameters:

• Programmable Type: EE PLD (Electrically Erasable Programmable Logic Device)
• Macrocell Count: 10 macrocells
• I/O Pin Count: 10 pins
• Propagation Delay: 7.5 ns maximum
• Supply Voltage Range: 4.75V ~ 5.25V
• Package Configuration: 28-pin PLCC with J-Lead termination
• Physical Dimensions: 11.51x11.51 mm
• Mounting Technology: Surface Mount

The ATF750C-7JX qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The ATF750C-7JX is the direct functional equivalent of the ATF750C-7JC. Both devices share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The primary distinction is product lifecycle status: the ATF750C-7JC is Obsolete, while the ATF750C-7JX maintains Active status with current manufacturing support.

The ATF750C-7JX offers improved regulatory compliance, meeting ROHS3 requirements compared to the non-compliant status of the ATF750C-7JC. The moisture sensitivity level differs between the two variants, with the ATF750C-7JX rated at MSL 3 (168 hours) versus MSL 2 (1 year) for the ATF750C-7JC. This difference reflects standard handling and storage protocols and does not affect functional performance in equivalent operating environments.

For new designs and production continuity, the ATF750C-7JX is the appropriate selection due to its Active product status and regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the ATF750C-7JX directly replace the ATF750C-7JC in existing designs?

A: Yes. The ATF750C-7JX is electrically and mechanically equivalent to the ATF750C-7JC. Both devices feature identical macrocell count, I/O configuration, propagation delay, supply voltage range, and 28-pin PLCC package dimensions. No circuit modifications are required for substitution.

Q: What is the significance of the different product status designations?

A: The ATF750C-7JC is classified as Obsolete, indicating discontinued manufacturing and limited availability. The ATF750C-7JX maintains Active status with ongoing production and supply chain support. For production planning and long-term availability, the ATF750C-7JX is the recommended choice.

Q: How do the RoHS compliance differences affect component selection?

A: The ATF750C-7JX meets ROHS3 compliance standards, while the ATF750C-7JC does not. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the ATF750C-7JX is the appropriate selection.

Q: What is the practical impact of the Moisture Sensitivity Level (MSL) difference?

A: The ATF750C-7JX is rated MSL 3 (168 hours), while the ATF750C-7JC is rated MSL 2 (1 year). MSL ratings define maximum exposure time to moisture before soldering. The ATF750C-7JX requires more stringent moisture control during storage and handling. Both devices are suitable for standard manufacturing environments with appropriate moisture management protocols.

Q: Are the packaging specifications identical between these two parts?

A: Yes. Both the ATF750C-7JC and ATF750C-7JX use the 28-pin PLCC package with J-Lead termination and identical physical dimensions of 11.51x11.51 mm. PCB footprints and assembly processes are interchangeable.
