Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT17F080-30JC is determined by strict equivalence across the following critical parameters:

• Memory capacity: 8Mb FLASH
• Package configuration: 20-LCC (J-Lead) / 20-PLCC (9x9)
• Supply voltage compatibility: 2.97V ~ 3.63V
• Mounting technology: Surface Mount
• Base product family: AT17F080 series

The AT17F080-30JU qualifies as a direct substitute based on identical memory size, programmable type, package geometry, and voltage specifications. Differences in operating temperature range and product status do not preclude substitution when system requirements align with the substitute's rated parameters.

Parameter Comparison

Engineering Selection Recommendations

The AT17F080-30JU is the direct equivalent for the obsolete AT17F080-30JC. Selection between these parts should be based on the following criteria:

For systems requiring industrial temperature range (0°C to 70°C): The AT17F080-30JC remains suitable if inventory is available. However, the AT17F080-30JU provides extended temperature coverage (-40°C to 85°C), enabling deployment across broader environmental conditions.

For new designs and long-term supply assurance: The AT17F080-30JU is the preferred choice due to active product status and ROHS3 compliance. The obsolete status of the AT17F080-30JC indicates limited future availability.

For regulatory compliance: The AT17F080-30JU meets ROHS3 requirements, whereas the AT17F080-30JC is non-compliant. Applications subject to RoHS directives must use the AT17F080-30JU.

For moisture-sensitive applications: The AT17F080-30JC carries MSL 2 (1 Year), while the AT17F080-30JU carries MSL 3 (168 Hours). Storage and handling protocols must reflect these classifications.

Frequently Asked Questions (FAQ)

Q: Can AT17F080-30JU replace AT17F080-30JC in existing designs?

A: Yes. Both parts share identical memory capacity (8Mb), supply voltage range (2.97V ~ 3.63V), and package configuration (20-PLCC). The AT17F080-30JU operates across a wider temperature range (-40°C to 85°C versus 0°C to 70°C), making it compatible with systems designed for the narrower range of the AT17F080-30JC.

Q: What is the significance of the product status difference?

A: The AT17F080-30JC is obsolete, indicating discontinued manufacturing and declining inventory availability. The AT17F080-30JU maintains active status, ensuring continued supply and manufacturing support. New designs should specify the active part.

Q: Are there packaging differences between these parts?

A: Both parts use identical 20-LCC (J-Lead) package configuration in 20-PLCC (9x9) supplier format. No PCB layout modifications are required for substitution.

Q: How do RoHS compliance differences affect selection?

A: The AT17F080-30JU is ROHS3 compliant, while the AT17F080-30JC is non-compliant. Applications subject to RoHS regulations or customer requirements mandating RoHS compliance must use the AT17F080-30JU.

Q: What moisture sensitivity level considerations apply?

A: The AT17F080-30JC (MSL 2, 1 Year) permits longer shelf life than the AT17F080-30JU (MSL 3, 168 Hours). Storage conditions and handling procedures must comply with the respective MSL ratings to prevent moisture-induced failures.
