PI3CH1000LE Equivalent & Substitute Parts

Part Overview

The PI3CH1000LE is a Bus Switch IC with 5 x 1:1 circuit configuration in a 24-TSSOP surface mount package, manufactured by Diodes Incorporated. This component is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part operates on single supply voltage between 2.25V and 3.6V with an operating temperature range of -40°C to 85°C. Due to its obsolete status, the SN74CBTLV3384PWR from Texas Instruments serves as the primary manufacturer-recommended substitute.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3CH1000LE is determined by strict equivalence across the following critical parameters:

• Circuit Type & Configuration: Both parts must function as Bus Switch with identical 5 x 1:1 circuit topology and 2 independent circuits
• Package Compatibility: Identical 24-TSSOP surface mount package ensures PCB layout compatibility without redesign
• Voltage Supply Range: The substitute must operate within the specified single supply voltage window (PI3CH1000LE: 2.25V ~ 3.6V; SN74CBTLV3384PWR: 2.3V ~ 3.6V)
• Temperature Operating Range: Both parts must support -40°C to 85°C operational envelope
• Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN/HTSUS classifications

The SN74CBTLV3384PWR meets all substitution criteria and carries Active product status, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

The SN74CBTLV3384PWR is the appropriate substitute for the obsolete PI3CH1000LE based on the following factors:

Product Status & Availability: The PI3CH1000LE is classified as Obsolete, whereas the SN74CBTLV3384PWR maintains Active status, ensuring continued manufacturing support and long-term supply chain stability.

Regulatory & Compliance Alignment: Both parts maintain identical ROHS3 compliance, REACH unaffected designation, and matching ECCN/HTSUS classifications, eliminating regulatory barriers to substitution.

Electrical & Mechanical Equivalence: The substitute provides identical bus switch functionality with matching 5 x 1:1 circuit topology, 2 independent circuits, and compatible voltage supply parameters across the specified operating temperature range.

Package Compatibility: The 24-TSSOP package is identical between both parts, enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SN74CBTLV3384PWR be used as a direct replacement for the PI3CH1000LE without PCB modifications?

A: Yes. Both parts share identical 24-TSSOP package dimensions and pin configurations, enabling direct footprint compatibility. No PCB layout changes are required.

Q: What is the voltage supply compatibility between these parts?

A: The PI3CH1000LE operates at 2.25V ~ 3.6V, while the SN74CBTLV3384PWR operates at 2.3V ~ 3.6V. The substitute covers the primary operating window with a 0.05V offset at the lower threshold. Both parts function across the standard 3.3V supply voltage used in most applications.

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

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and matching ECCN/HTSUS classifications. Substitution does not introduce regulatory compliance issues.

Q: Why is the PI3CH1000LE classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The SN74CBTLV3384PWR, with Active status, provides equivalent functionality with assured ongoing availability.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture handling and storage requirements.

Q: What are the independent circuits in this bus switch configuration?

A: Both parts feature 2 independent circuits within the 5 x 1:1 bus switch topology, allowing simultaneous switching control of multiple signal paths.
