Substitute Part Grouping Explanation

The ATF750CL-15PU qualifies as a direct substitute for the ATF750CL-15PI based on strict equivalence across all critical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Identical programmable type (EE PLD)
• Matching macrocell count (10)
• Matching I/O pin count (10)
• Identical maximum propagation delay (15 ns)
• Identical voltage supply range (4.5V ~ 5.5V)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical package type and dimensions (24-DIP, 0.300", 7.62mm)
• Identical supplier device package designation (24-PDIP)

The primary distinction between these parts is product status and packaging format, not functional capability.

Engineering Selection Recommendations

The ATF750CL-15PU is the appropriate selection for new designs and production applications requiring ATF750 series CPLD functionality. This part maintains active product status with Microchip Technology, ensuring continued availability and supply chain reliability. The ATF750CL-15PU achieves ROHS3 compliance, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. Both parts share identical electrical performance characteristics and package specifications, enabling direct substitution at the board level without design modification.

For legacy systems currently utilizing the obsolete ATF750CL-15PI, migration to the ATF750CL-15PU is supported by functional equivalence across all specified parameters. The packaging format difference (tube versus original packaging) does not affect electrical performance or mechanical compatibility in through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the ATF750CL-15PU directly replace the ATF750CL-15PI in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including macrocell count, I/O configuration, propagation delay, voltage supply range, operating temperature range, and package dimensions. Direct substitution is supported without circuit modification.

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

A: The ATF750CL-15PI is classified as obsolete, indicating discontinued manufacturing and limited availability. The ATF750CL-15PU maintains active status, ensuring ongoing production, supply availability, and manufacturer support. For new designs and production applications, the active part is the appropriate selection.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: The RoHS compliance difference reflects manufacturing process updates. The ATF750CL-15PU achieves ROHS3 compliance, meeting current environmental standards. This does not affect electrical or mechanical compatibility. For applications subject to RoHS requirements, the ATF750CL-15PU is the required selection.

Q: Are the packaging formats interchangeable?

A: Both parts use identical 24-DIP (0.300", 7.62mm) package specifications and 24-PDIP supplier device packages. The packaging format designation (tube for the substitute) does not affect electrical performance or through-hole mounting compatibility. Board-level integration is identical.

Q: What parameters determine substitution eligibility for ATF750 series devices?

A: Substitution is determined by equivalence in programmable type, macrocell count, I/O pin count, maximum propagation delay, voltage supply range, operating temperature range, and package type. All specified parameters must match for direct substitution.
