Engineering Selection Recommendations
Primary Substitutes (Identical Electrical & Package Specifications):
For direct replacement in 48-BSSOP packaging with matching 24mA output current specifications, the 74FCT162245ATPVCT (Cypress Semiconductor) is the preferred substitute. This part maintains active product status, ensuring long-term availability and supply chain stability compared to the obsolete original part.
Secondary Substitutes (Identical Electrical, Alternative Package):
For applications where 48-TFSOP packaging is acceptable, the 74FCT162245ATPACT (Texas Instruments) provides electrical equivalence with identical 24mA output current ratings. This part is suitable for new PCB designs or rework scenarios where package footprint flexibility exists.
Alternative Substitutes (Higher Output Current Capability):
Parts such as CY74FCT16245ATPACT and CY74FCT16245ATPVC feature elevated output current specifications (32mA high, 64mA low) compared to the original 24mA ratings. These parts are electrically compatible but provide enhanced drive capability. Selection of these alternatives is appropriate only when the application circuit can accommodate the increased current output without adverse effects.
Compliance Considerations:
All listed substitutes maintain REACH Unaffected or ROHS3 Compliant status, ensuring regulatory alignment with the original part. Moisture Sensitivity Level 1 (Unlimited) is consistent across all qualified substitutes.
Frequently Asked Questions (FAQ)
Q: Can I use CY74FCT162245TPVCT as a direct replacement for 74FCT162H245CTPVG?
A: Yes. Both parts share identical electrical specifications (24mA output current, 4.5V–5.5V supply, -40°C to 85°C operating range) and are packaged in 48-BSSOP. The CY74FCT162245TPVCT maintains active product status, making it a suitable long-term substitute.
Q: What is the difference between 48-BSSOP and 48-TFSOP packages?
A: Both are 48-pin surface mount packages with compatible pinouts for this logic family. The 48-BSSOP has a 0.295" (7.50mm) width, while the 48-TFSOP has a 0.240" (6.10mm) width. Package selection depends on PCB layout constraints and available footprint space.
Q: Why do some substitutes list higher output current (32mA/64mA) instead of 24mA/24mA?
A: Parts such as 74FCT16245TPVCG4 and CY74FCT16245ATPACT are based on the 74FCT16245 base product number rather than 74FCT162245, resulting in higher output drive capability. These parts are electrically compatible but should only be selected if the application circuit design supports the increased current output.
Q: Are all substitutes ROHS compliant?
A: Most listed substitutes carry ROHS3 Compliant status. The original 74FCT162H245CTPVG is REACH Unaffected. Verify specific compliance requirements for your application before final part selection.
Q: What is the significance of product status (Active vs. Obsolete)?
A: Active status indicates ongoing manufacturer support and supply availability. Obsolete status indicates the part is no longer in production. For new designs or long-term production, prioritize active parts such as CY74FCT162245TPVCT to ensure sustained supply chain access.
Q: Can I substitute parts with different packaging in the same PCB?
A: No. PCB footprints are specific to package type. A 48-BSSOP footprint cannot accommodate a 48-TFSOP package. Package changes require PCB redesign and re-layout.
