Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CY29FCT520ATSOCT is determined by strict equivalence across the following critical parameters:

• Logic Type: Register, Pipeline (8-bit, 1 element configuration)
• Output Type: Tri-State
• Voltage Supply Range: 4.75V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 24-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

The CY29FCT520ATSOC meets all substitution criteria as a direct equivalent. The primary distinction is product status: the substitute part is active in production, whereas the main part is obsolete. Both parts share identical electrical specifications, mechanical packaging, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CY29FCT520ATSOC is the direct substitute for the obsolete CY29FCT520ATSOCT. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The substitute part carries active product status, ensuring continued availability for procurement and support. Both parts satisfy ROHS3 compliance requirements and carry equivalent regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001). Selection of the active substitute part eliminates obsolescence risk while maintaining full functional and physical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can CY29FCT520ATSOC be used as a direct replacement for CY29FCT520ATSOCT?

A: Yes. Both parts are electrically and mechanically identical. The substitute part is active in production, whereas the main part is obsolete. No design modifications are required for substitution.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 24-SOIC package with 0.295" width and 7.50mm width specification. PCB footprints and assembly processes remain unchanged.

Q: Do both parts operate within the same voltage and temperature ranges?

A: Yes. Both parts operate at 4.75V to 5.5V supply voltage and function across the -40°C to 85°C temperature range.

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

A: The main part (CY29FCT520ATSOCT) is obsolete and no longer manufactured. The substitute part (CY29FCT520ATSOC) is active and available for new orders. For ongoing production and support, the active substitute part is the appropriate selection.

Q: Are there any compliance or certification differences?
