PI3C3861LE Bus Switch 10 x 1:1 Equivalent & Substitute Parts
Part Overview
The PI3C3861LE is a Bus Switch IC with 10 x 1:1 circuit configuration in 24-TSSOP packaging, manufactured by Diodes Incorporated. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates with single supply voltage ranging from 2.3V to 3.6V and supports operating temperatures from -40°C to 85°C. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Engineering Selection Recommendations
All three substitute parts are active products with full parametric equivalence to the obsolete PI3C3861LE. Selection among these alternatives should be based on the following factors:
SN74CB3Q6800PW (Texas Instruments): Active product status with ROHS3 compliance and REACH Unaffected certification. Supplied in Tube packaging with 1875 units in stock.
74CBTLV3861PGG (IDT, Integrated Device Technology Inc): Active product status with EAR99 classification. Supplied in Bulk packaging with 1454 units in stock. Compliance certifications not fully specified in available data.
SN74CBTLV3861PW (Texas Instruments): Active product status with ROHS3 compliance, MSL 1 rating, and REACH Unaffected certification. Supplied in Tube packaging with 2040 units in stock. Highest inventory availability among substitutes.
All parts meet the electrical and mechanical requirements for direct replacement. Selection may be influenced by packaging preference (Tube vs. Bulk), inventory availability, and supply chain considerations.
Frequently Asked Questions (FAQ)
Q: Can SN74CB3Q6800PW, 74CBTLV3861PGG, and SN74CBTLV3861PW be used interchangeably with PI3C3861LE?
A: Yes. All three parts are parametrically equivalent across circuit configuration (10 x 1:1 Bus Switch), voltage supply range (2.3V ~ 3.6V), operating temperature (-40°C ~ 85°C), and package type (24-TSSOP). They are suitable for direct replacement in applications requiring PI3C3861LE functionality.
Q: Are there differences in packaging between the substitute parts?
A: Yes. SN74CB3Q6800PW and SN74CBTLV3861PW are supplied in Tube packaging, while 74CBTLV3861PGG is supplied in Bulk packaging. The mechanical package (24-TSSOP) is identical across all parts.
Q: What is the significance of the obsolete status of PI3C3861LE?
A: Obsolete status indicates that Diodes Incorporated has discontinued this part. The listed substitutes are active products from alternative manufacturers, ensuring continued availability and supply chain reliability for new designs and production runs.
Q: Do all substitute parts meet compliance requirements?
A: SN74CB3Q6800PW and SN74CBTLV3861PW are confirmed ROHS3 compliant with REACH Unaffected status. Compliance certifications for 74CBTLV3861PGG are not fully specified in available documentation. All parts carry EAR99 export classification.
Q: Which substitute part has the highest inventory availability?
A: SN74CBTLV3861PW from Texas Instruments has 2040 units in stock, providing the highest inventory level among the three substitutes.
