PI3CH401LEX Equivalent & Substitute Parts

Part Overview

The PI3CH401LEX is a bus switch IC manufactured by Diodes Incorporated, designed for single supply operation in logic applications. This 1 x 1:1 bus switch integrates four independent circuits in a 14-TSSOP surface mount package. The device operates across a supply voltage range of 2.25V to 3.6V and maintains functionality across the industrial temperature range of -40°C to 85°C. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the PI3CH401LEX serves applications requiring reliable signal switching in compact form factors. Equivalent substitute parts are identified to provide procurement flexibility while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3CH401LEX is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: 1 x 1:1 topology with 4 independent circuits
• Voltage Supply Range: 2.25V ~ 3.6V single supply operation
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 14-TSSOP surface mount form factor
• Electrical Characteristics: Identical bus switch functionality
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The PI3CH400LEX qualifies as a parametric equivalent based on matching all electrical specifications, circuit topology, supply voltage requirements, temperature range, and package configuration. Packaging format differences (tape & reel versus standard packaging) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the PI3CH401LEX and PI3CH400LEX are active products from Diodes Incorporated with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on packaging format availability and procurement requirements rather than functional differences. The PI3CH401LEX is available in standard packaging with 1742 units in stock, while the PI3CH400LEX is supplied in tape & reel format with 2600 units in stock. For high-volume production environments requiring tape & reel packaging, the PI3CH400LEX provides equivalent functionality with greater inventory availability. For applications requiring standard packaging, the PI3CH401LEX remains the primary selection. Both parts maintain identical electrical performance, temperature ratings, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Are PI3CH401LEX and PI3CH400LEX electrically interchangeable?

A: Yes. Both parts feature identical circuit topology (1 x 1:1 with 4 independent circuits), supply voltage range (2.25V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and package configuration (14-TSSOP). Electrical performance is equivalent.

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

A: The primary difference is packaging format. The PI3CH401LEX uses standard packaging, while the PI3CH400LEX is supplied in tape & reel format. This distinction affects procurement and assembly processes but not functional performance.

Q: Can I use PI3CH400LEX as a direct replacement for PI3CH401LEX on a PCB?

A: Yes. Both parts use the identical 14-TSSOP surface mount package with matching pinout and electrical characteristics. PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PI3CH401LEX and PI3CH400LEX are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which part should I select for new designs?

A: Selection depends on procurement requirements. For standard packaging applications, use PI3CH401LEX. For high-volume production with tape & reel assembly processes, use PI3CH400LEX. Both are active products with equivalent long-term availability.
