Substitute Part Grouping Explanation

Substitution for the EPF8282ALC84-2 is determined by the following critical parameters:

• Package Compatibility: 84-LCC (J-Lead) surface mount package with identical physical dimensions (29.31x29.31mm)
• I/O Pin Count: Minimum 68 I/O pins required; higher pin counts are acceptable
• Logic Capacity: Minimum 208 logic elements; higher gate counts provide design flexibility
• Supply Voltage: Compatibility with 4.75V ~ 5.25V operating range
• Operating Temperature Range: 0°C ~ 70°C (TA) or broader
• Mounting Type: Surface mount configuration

The A40MX04-PLG84 meets these substitution criteria while offering enhanced capabilities and active product status.

Engineering Selection Recommendations

The A40MX04-PLG84 is a direct substitute for the EPF8282ALC84-2 based on the following engineering criteria:

• Package Compatibility: Both devices use identical 84-LCC (J-Lead) surface mount packages with matching physical dimensions, ensuring PCB layout compatibility without redesign.
• I/O Pin Count: The A40MX04-PLG84 provides 69 I/O pins, exceeding the 68-pin requirement of the EPF8282ALC84-2, allowing full functional replacement.
• Logic Capacity: The A40MX04-PLG84 offers 6000 gates compared to 2500 gates in the original part, providing increased design headroom and future scalability.
• Supply Voltage Range: The A40MX04-PLG84 supports both 3V ~ 3.6V and 4.75V ~ 5.25V ranges, maintaining compatibility with existing 5V systems while enabling lower-voltage applications.
• Operating Temperature: Both devices operate across 0°C ~ 70°C, ensuring thermal compatibility.
• Product Status: The A40MX04-PLG84 is active and widely available, eliminating obsolescence concerns associated with the EPF8282ALC84-2.
• Compliance: The A40MX04-PLG84 is ROHS3 compliant, meeting modern environmental and regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the A40MX04-PLG84 directly replace the EPF8282ALC84-2 without PCB modifications?

A: Yes. Both devices use the 84-LCC (J-Lead) package with identical physical dimensions (29.31x29.31mm) and surface mount configuration. No PCB layout changes are required for package compatibility.

Q: Are there any voltage compatibility concerns when substituting?

A: No. The A40MX04-PLG84 supports the 4.75V ~ 5.25V range required by the EPF8282ALC84-2. The additional 3V ~ 3.6V capability provides design flexibility for lower-voltage applications but does not affect 5V system compatibility.

Q: Does the higher gate count of the A40MX04-PLG84 affect compatibility?

A: No. Higher gate count and logic capacity provide additional design resources without compromising backward compatibility. Designs targeting the EPF8282ALC84-2 will function on the A40MX04-PLG84 with available headroom for future enhancements.

Q: What is the significance of the extra I/O pin on the A40MX04-PLG84?

A: The A40MX04-PLG84 provides 69 I/O pins versus 68 on the EPF8282ALC84-2. This additional pin offers expanded I/O capability while maintaining full compatibility with designs using 68 pins.

Q: Are there any moisture sensitivity or handling differences?

A: Both devices have identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours), requiring the same storage and handling procedures.

Q: Why is the EPF8282ALC84-2 classified as obsolete?

A: The EPF8282ALC84-2 is part of the legacy FLEX 8000 series, which has been superseded by newer FPGA architectures. The A40MX04-PLG84 from the active MX series represents the current technology generation with enhanced capabilities and ongoing manufacturer support.
