Substitute Part Grouping Explanation

Substitution of the ATF1504ASVL-20AI100 is determined by strict equivalence across the following critical parameters:

• Macrocell count: 64 macrocells
• I/O pin count: 64 pins
• Package type: 100-TQFP (14x14)
• Propagation delay: 20 ns maximum
• Supply voltage range: 3V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• Programming capability: In-system programmable
• Mounting configuration: Surface mount

The ATF1504ASVL-20AU100 meets all electrical and mechanical requirements for direct substitution. The primary distinction between these parts is packaging format (tray vs. tube) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The ATF1504ASVL-20AU100 is the direct functional equivalent of the ATF1504ASVL-20AI100. Both devices share identical electrical specifications, pin configurations, and performance characteristics. The substitute part offers the advantage of active product status and ROHS3 compliance, whereas the original part is classified as obsolete and RoHS non-compliant. For new designs or system refreshes, the ATF1504ASVL-20AU100 is the appropriate selection. For legacy system maintenance requiring exact part matching, the ATF1504ASVL-20AI100 remains functionally interchangeable where available inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the ATF1504ASVL-20AU100 be used as a direct replacement for the ATF1504ASVL-20AI100?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters, including macrocell count, I/O configuration, propagation delay, supply voltage, operating temperature range, and package dimensions. The devices are pin-for-pin compatible.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance certification. The ATF1504ASVL-20AU100 is an active product with ROHS3 compliance, while the ATF1504ASVL-20AI100 is obsolete and RoHS non-compliant. The packaging format also differs: the substitute uses tray packaging versus tube packaging for the original.

Q: Are there any performance differences between these parts?

A: No. Both devices deliver identical performance specifications: 64 macrocells, 64 I/O pins, 20 ns maximum propagation delay, 3V to 3.6V supply voltage, and -40°C to 85°C operating temperature range.

Q: Does the packaging format (tray vs. tube) affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. The difference is administrative, relating to component handling and storage. Both formats accommodate the same 100-TQFP (14x14) package dimensions and surface mount configuration.

Q: Which part should be selected for new designs?

A: The ATF1504ASVL-20AU100 is the appropriate choice for new designs due to its active product status and regulatory compliance certifications.
