Engineering Selection Recommendations
All listed 74FCT3807 variants from Renesas Electronics Corporation are active products with ROHS3 compliance and MSL 1 rating, making them suitable for direct substitution in applications currently using the obsolete PCK3807AD,112.
Selection among 74FCT3807 variants should be based on:
Operating Temperature Requirements:
- For applications requiring -40°C ~ 85°C operation: Select 74FCT3807ASOGI, 74FCT3807ASOGI8, 74FCT3807SOGI, or 74FCT3807SOGI8
- For applications with 0°C ~ 70°C operation: Any variant is acceptable
Packaging Format:
- Tube packaging: 74FCT3807ASOG, 74FCT3807ASOGI, 74FCT3807SOG, 74FCT3807SOGI
- Tape & Reel (TR) packaging: 74FCT3807ASOG8, 74FCT3807ASOGI8, 74FCT3807SOG8, 74FCT3807SOGI8
Frequency Consideration: The 74FCT3807 series operates at maximum 100 MHz, compared to the PCK3807AD,112 at 400 MHz. Applications requiring frequencies above 100 MHz require alternative solutions outside this substitute group.
Frequently Asked Questions (FAQ)
Q: Can the 74FCT3807 series directly replace the PCK3807AD,112 in all applications?
A: Direct replacement is possible for applications operating at or below 100 MHz. The PCK3807AD,112 supports 400 MHz operation, while 74FCT3807 variants are rated to 100 MHz maximum. Applications requiring higher frequency operation require alternative components.
Q: What is the difference between tube and tape & reel packaging variants?
A: Tube packaging (variants without "8" suffix) and Tape & Reel packaging (variants with "8" suffix) contain identical electrical and functional specifications. The difference is in packaging format for handling and automated assembly. Selection depends on manufacturing process requirements and inventory management practices.
Q: Which 74FCT3807 variant should I select for extended temperature applications?
A: For applications requiring -40°C ~ 85°C operation, select variants with "I" designation: 74FCT3807ASOGI, 74FCT3807ASOGI8, 74FCT3807SOGI, or 74FCT3807SOGI8. Variants without "I" designation are rated for 0°C ~ 70°C operation only.
Q: Are all substitute parts RoHS compliant?
A: Yes. All listed 74FCT3807 variants are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the compliance profile of the PCK3807AD,112.
Q: What is the supply voltage compatibility?
A: The PCK3807AD,112 operates at 2.3V ~ 3.6V, while 74FCT3807 variants operate at 3V ~ 3.6V. The 74FCT3807 series does not support operation below 3V. Verify that your application supply voltage meets the 3V minimum requirement before substitution.
