Substitute Part Grouping Explanation

Substitution of the AT17F16-30JC is determined by strict equivalence across the following critical parameters:

• Memory capacity: 16Mb FLASH
• Programmable type: FLASH memory technology
• Supply voltage range: 2.97V ~ 3.63V
• Physical package: 20-LCC (J-Lead) / 20-PLCC (9x9)
• Mounting configuration: Surface mount
• Base product family: AT17F16 series

The AT17F16-30JU qualifies as a direct substitute based on identical memory specifications, voltage requirements, and physical packaging. Differences in operating temperature range and product status do not preclude substitution when system thermal requirements are compatible with the substitute's extended temperature rating.

Parameter Comparison

Engineering Selection Recommendations

The AT17F16-30JU is the qualified substitute for the obsolete AT17F16-30JC. Both devices share identical memory capacity, voltage specifications, and physical packaging, ensuring direct functional compatibility at the circuit level.

The AT17F16-30JU offers two significant advantages: active product status ensures continued availability and manufacturer support, and ROHS3 compliance satisfies modern regulatory requirements. The extended operating temperature range (-40°C to 85°C) of the AT17F16-30JU encompasses the original part's specification (0°C to 70°C), providing broader environmental tolerance without compromising performance within the original operating window.

Selection of the AT17F16-30JU is appropriate for new designs and legacy system support where component obsolescence necessitates substitution.

Frequently Asked Questions (FAQ)

Q: Can the AT17F16-30JU directly replace the AT17F16-30JC in existing applications?

A: Yes. Both devices are electrically and mechanically equivalent. They share identical memory capacity (16Mb), supply voltage range (2.97V to 3.63V), and physical packaging (20-LCC / 20-PLCC 9x9). The substitute's extended temperature rating does not affect compatibility within the original part's operating range.

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

A: The AT17F16-30JC is classified as obsolete, indicating discontinued manufacturing and limited availability. The AT17F16-30JU maintains active status, ensuring ongoing production, inventory availability, and manufacturer technical support.

Q: How do the RoHS compliance differences affect substitution?

A: The AT17F16-30JC is RoHS non-compliant, while the AT17F16-30JU is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the AT17F16-30JU is the mandated choice. For legacy systems without such constraints, both parts remain functionally interchangeable.

Q: Are the packaging and moisture sensitivity specifications identical?

A: Yes. Both parts use the 20-PLCC (9x9) package with 20-LCC (J-Lead) configuration and share identical Moisture Sensitivity Level (MSL) rating of 2 (1 Year). Handling and storage protocols are equivalent.

Q: What export control classifications apply to these parts?

A: Both the AT17F16-30JC and AT17F16-30JU carry identical ECCN (3A991B1A) and HTSUS (8542.32.0071) classifications, ensuring consistent regulatory treatment for procurement and logistics.
