Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74CBT6800APWR is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 10 x 1:1 bus switch topology
• Package type: 24-TSSOP form factor with identical pin pitch and dimensions
• Voltage supply range: 4V ~ 5.5V single supply operation
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface mount technology
• Compliance certifications: ROHS3, REACH Unaffected status

The SN74CBT6800CPWR meets all these criteria and is therefore a direct parametric equivalent. The primary difference between these parts is packaging format: the APWR uses Cut Tape (CT) packaging, while the CPWR uses Tape & Reel (TR) packaging. This distinction affects procurement and handling but does not impact electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SN74CBT6800CPWR is a direct substitute for the SN74CBT6800APWR based on complete electrical and mechanical parameter equivalence. Both parts share identical circuit topology, voltage specifications, temperature ratings, and package dimensions. The CPWR variant maintains Active product status, ensuring continued availability and supply chain stability compared to the APWR's Last Time Buy designation.

Selection between these parts should be based on procurement requirements: Cut Tape packaging suits lower-volume or prototype applications, while Tape & Reel packaging is optimized for high-volume automated assembly. Both variants meet ROHS3 and REACH compliance requirements, making them suitable for equivalent applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can the SN74CBT6800CPWR be used as a direct replacement for the SN74CBT6800APWR?

A: Yes. Both parts are electrically and mechanically identical. They share the same circuit configuration, voltage supply range, operating temperature range, package type, and pin configuration. The only difference is packaging format (Cut Tape versus Tape & Reel).

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual component strips suitable for manual handling and lower-volume applications. Tape & Reel (TR) packaging supplies components on continuous reels optimized for automated pick-and-place assembly in high-volume production. Both formats contain identical components with no electrical differences.

Q: Why is the SN74CBT6800APWR listed as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific part variant. The SN74CBT6800CPWR remains in Active status, making it the recommended choice for new designs and ongoing production requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SN74CBT6800APWR and SN74CBT6800CPWR carry identical ROHS3 Compliant and REACH Unaffected certifications. They are equivalent for regulatory and environmental compliance purposes.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage practices apply.
