PI3C3306LE Equivalent & Substitute Parts

Part Overview

The PI3C3306LE is a Bus Switch logic IC manufactured by Diodes Incorporated, configured as a 1 x 1:1 circuit in an 8-TSSOP surface mount package. This component operates across a single supply voltage range of 2.3V to 3.6V and maintains functionality across the industrial temperature range of -40°C to 85°C. The part is currently in Last Time Buy status, making identification of equivalent alternatives essential for ongoing design support and procurement planning. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI3C3306LE are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters:

• Bus Switch type with 1 x 1:1 circuit configuration
• 2 independent circuits
• Single supply voltage operation at 2.3V ~ 3.6V
• Operating temperature range of -40°C ~ 85°C

Mechanical Parameters:

• 8-TSSOP package with 0.173" (4.40mm) width
• Surface mount mounting type

Compliance Parameters:

• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

All substitute parts listed maintain these specifications without deviation. Packaging format (Tube vs. Tape & Reel) represents a procurement variation and does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Recommendation: SN74CB3Q3306APWR

The SN74CB3Q3306APWR (Texas Instruments) is the preferred substitute for the PI3C3306LE. This part maintains Active product status, ensuring long-term availability and continued manufacturer support. All electrical and mechanical parameters are identical to the original part. The Tape & Reel packaging format is suitable for high-volume production environments.

Secondary Recommendations: SN74CB3Q3305PW and SN74CB3Q3306APW

Both SN74CB3Q3305PW and SN74CB3Q3306APW are parametric equivalents with identical electrical specifications and mechanical compatibility. Both are supplied in Tube packaging, matching the original PI3C3306LE format. Both parts carry Last Time Buy status, similar to the original component. These options are suitable for applications where packaging format consistency with the original design is required.

Compliance Assurance

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring regulatory and environmental compatibility with the original design specifications.

Frequently Asked Questions (FAQ)

Q: Can SN74CB3Q3306APWR be used as a direct replacement for PI3C3306LE?

A: Yes. The SN74CB3Q3306APWR is a direct electrical and mechanical equivalent. All critical parameters—circuit configuration, voltage supply range, operating temperature, package type, and compliance certifications—are identical. The only difference is the packaging format (Tape & Reel vs. Tube), which does not affect component functionality.

Q: What is the difference between SN74CB3Q3305PW and SN74CB3Q3306APW?

A: Both parts are parametric equivalents with identical electrical specifications and mechanical compatibility to the PI3C3306LE. The primary difference is the base product number designation (74CB3Q3305 vs. 74CB3Q3306), which reflects internal Texas Instruments product line organization. Both are functionally interchangeable for this application.

Q: Does packaging format (Tube vs. Tape & Reel) affect compatibility?

A: No. Packaging format is a procurement and handling specification only. It does not affect electrical performance, mechanical fit, or functional compatibility. Selection between Tube and Tape & Reel packaging should be based on production volume and assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original PI3C3306LE specifications.

Q: What should be considered when selecting between Active and Last Time Buy status parts?

A: The SN74CB3Q3306APWR carries Active status, indicating ongoing manufacturer support and long-term availability. The SN74CB3Q3305PW and SN74CB3Q3306APW carry Last Time Buy status, similar to the original PI3C3306LE. For new designs or long-term production, the Active status part is recommended. For legacy system support or existing inventory management, Last Time Buy parts may be appropriate.
