Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LVC1G99DCUTG4 is determined by strict equivalence across the following critical parameters:

• Base product number (74LVC1G99)
• Logic type (Configurable Multiple Function)
• Circuit and input configuration (1 circuit, 4 inputs)
• Output type (Tri-State)
• Electrical specifications (32mA output current, 1.65V–5.5V supply voltage, -40°C to 125°C operating range)
• Package type (8-VFSOP)
• Compliance certifications (ROHS3, REACH Unaffected)

The substitute part SN74LVC1G99DCUT differs only in packaging format (Tape & Reel versus individual unit packaging) and product status (Active versus Discontinued), with all functional and electrical parameters remaining identical.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC1G99DCUT is a direct functional equivalent to the SN74LVC1G99DCUTG4. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are housed in the same 8-VFSOP package. The primary distinction is product status: the original part is discontinued at DiGi Electronics, while the substitute maintains active status with confirmed inventory availability (2000 pcs). Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in equivalent applications.

For new designs or procurement requiring the 74LVC1G99 configurable logic function, the SN74LVC1G99DCUT is the recommended selection due to active product status and sustained supply chain availability. Existing designs using the SN74LVC1G99DCUTG4 can transition to the substitute without circuit modification, provided packaging format (Tape & Reel) is compatible with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC1G99DCUT replace SN74LVC1G99DCUTG4 in existing designs?

A: Yes. Both parts are electrically and functionally identical. The substitute maintains the same logic type, circuit configuration, output specifications, supply voltage range, operating temperature range, and package dimensions. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The SN74LVC1G99DCUTG4 is supplied in individual unit packaging, while the SN74LVC1G99DCUT is supplied in Tape & Reel format. The original part is discontinued at DiGi Electronics; the substitute is active. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory status is equivalent.

Q: Is the 8-VFSOP package compatible with standard surface mount assembly?

A: Yes. Both parts use the 8-VFSOP (0.091", 2.30mm Width) package, which is a standard surface mount package compatible with conventional pick-and-place and reflow assembly processes.

Q: What is the supply voltage range for this part?

A: Both the original and substitute parts operate across 1.65V to 5.5V supply voltage, supporting applications in low-voltage and standard logic environments.
