Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LS00DG4 is determined by strict equivalence across the following electrical and mechanical parameters:

• Logic function: NAND Gate with identical circuit count (4) and input configuration (2-input)
• Electrical specifications: Supply voltage range, output current ratings, input logic levels, and propagation delay must match exactly
• Package type: 14-SOIC surface mount configuration with identical physical dimensions
• Series classification: 74LS logic family standard

Parts meeting all these criteria are classified as direct substitutes. Variations in product status, manufacturer, or compliance certifications do not affect functional equivalence but may impact procurement availability and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

SN74LS00DR is the primary substitute for SN74LS00DG4. Both parts are manufactured by Texas Instruments with identical electrical and mechanical specifications. SN74LS00DR maintains active product status and ROHS3 compliance, providing continuity for new designs and ongoing production requirements.

SN74LS00D, manufactured by onsemi, provides functional equivalence with matching electrical and package specifications. However, this part carries obsolete product status and does not meet RoHS3 compliance requirements. Selection of SN74LS00D is appropriate only when legacy system maintenance or specific procurement constraints necessitate onsemi sourcing.

Frequently Asked Questions (FAQ)

Q: Can SN74LS00DR be used as a direct replacement for SN74LS00DG4?

A: Yes. Both parts share identical logic function, electrical specifications, and 14-SOIC package configuration. No circuit modifications are required.

Q: What is the difference between SN74LS00DG4 and SN74LS00DR?

A: The parts are electrically and functionally equivalent. The primary difference is packaging format: SN74LS00DG4 uses standard packaging while SN74LS00DR is supplied in Cut Tape and Digi-Reel formats. SN74LS00DR also maintains active product status.

Q: Is SN74LS00D a suitable alternative?

A: SN74LS00D meets all electrical and mechanical requirements for functional substitution. However, it carries obsolete product status and does not comply with RoHS3 standards. Use only when specific design or procurement requirements mandate onsemi sourcing.

Q: Are there any package compatibility concerns with these substitutes?

A: No. All three parts use the 14-SOIC package with identical physical dimensions (0.154" width, 3.90mm). PCB footprints and assembly processes remain unchanged.

Q: What compliance certifications apply to each substitute?

A: SN74LS00DG4 and SN74LS00DR both carry ROHS3 compliance certification. SN74LS00D does not meet RoHS3 requirements. All three parts are REACH Unaffected and classified as EAR99 for export control purposes.
