Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74F00SCX is determined by strict equivalence across the following parameters:

• Logic function: 4-channel 2-input NAND gate
• Electrical specifications: 4.5V ~ 5.5V supply, 1mA/20mA output current, 0.8V/2V input logic levels, 5ns propagation delay
• Operating temperature range: 0°C ~ 70°C
• Surface mount technology
• 14-pin SOIC package family

Substitute parts are classified into two categories:

Direct Equivalents maintain identical package dimensions (14-SOIC, 0.154" width, 3.90mm). These parts are pin-compatible and footprint-compatible with the 74F00SCX.

Similar Equivalents maintain identical electrical and functional specifications but use a variant package within the 14-SOIC family (0.209" width, 5.30mm). These parts are pin-compatible but require PCB footprint verification before substitution.

Parameter Comparison

Engineering Selection Recommendations

SN74F00DR is the primary substitute for the 74F00SCX. This part is manufactured by Texas Instruments with active product status, ensuring long-term availability. It maintains identical electrical specifications and package dimensions (14-SOIC, 0.154" width). The part is ROHS3 compliant and supplied in Tape & Reel packaging suitable for automated assembly. Inventory availability is 44,744 pieces.

SN74F00D is an alternative substitute with identical electrical and package specifications. This part carries Last Time Buy status from Texas Instruments, indicating limited future availability. It is supplied in Tube packaging and is ROHS3 compliant. Inventory availability is 8,600 pieces.

SN74F00NSR is a compatible substitute with identical electrical specifications but uses a wider 14-SOIC package variant (0.209" width, 5.30mm versus 0.154" width, 3.90mm). This part is manufactured by Texas Instruments with active product status and ROHS3 compliance. PCB footprint verification is required before substitution due to package width difference. Inventory availability is 2,100 pieces.

Frequently Asked Questions (FAQ)

Q: Can SN74F00DR be used as a direct replacement for 74F00SCX?

A: Yes. SN74F00DR maintains identical electrical specifications, pin configuration, and package dimensions (14-SOIC, 0.154" width). No circuit modifications are required. The part is pin-compatible and footprint-compatible.

Q: What is the difference between SN74F00D and SN74F00DR?

A: Both parts are electrically identical with matching specifications and package dimensions. The primary difference is packaging format: SN74F00D is supplied in Tube packaging, while SN74F00DR is supplied in Tape & Reel (TR) format. SN74F00DR is recommended for automated assembly processes. SN74F00D carries Last Time Buy status, indicating reduced future availability.

Q: Can SN74F00NSR replace 74F00SCX on existing PCBs?

A: SN74F00NSR is electrically equivalent but uses a wider 14-SOIC package (0.209" width versus 0.154" width). The pin configuration remains identical, but the package footprint differs. Substitution requires PCB footprint verification and may not be compatible with existing board layouts designed for the narrower package variant.

Q: Are all substitute parts ROHS3 compliant?

A: SN74F00D and SN74F00DR are ROHS3 compliant. The original 74F00SCX does not specify RoHS status. All substitute parts meet REACH requirements and carry EAR99 ECCN classification.

Q: What is the product status significance for these parts?

A: SN74F00DR carries Active status, ensuring continued manufacturing and availability. SN74F00D is Last Time Buy, indicating limited production windows and eventual discontinuation. The original 74F00SCX is Obsolete, making substitution necessary for new designs and ongoing production support.
