PI3B3257LE-2017 Equivalent & Substitute Parts

Part Overview

The PI3B3257LE-2017 is a 4 x 2:1 Multiplexer/Demultiplexer logic IC manufactured by Diodes Incorporated in a 16-TSSOP surface mount package. This component is classified as Active product status with 960 units currently in stock. The PI3B3257LE-2017 operates on single supply voltage ranging from 3V to 3.6V and supports operating temperatures from -40°C to 125°C. Substitute parts become necessary when the original component reaches end-of-life status, experiences supply constraints, or when design requirements necessitate alternative circuit configurations or voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3B3257LE-2017 is determined by the following critical parameters:

Primary Substitution Criteria:

• Package type: 16-TSSOP (0.173", 4.40mm Width)
• Mounting type: Surface Mount
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)
• Voltage Supply Source: Single Supply

Functional Compatibility Considerations:

• Circuit configuration (4 x 2:1 vs. 4 x 1:2) affects pin assignment and signal routing
• Independent circuits count (1 vs. 4) determines functional topology
• Voltage supply range compatibility (3V ~ 3.6V vs. 2.3V ~ 3.6V)
• Operating temperature range (original: -40°C ~ 125°C vs. substitute options: -40°C ~ 85°C)

Substitute parts are grouped into two functional categories: direct 4 x 2:1 configuration matches and alternative 4 x 1:2 configuration options. Both categories maintain identical package specifications and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Functional Equivalents (4 x 2:1 Configuration):

SN74CB3Q3257PWR is the primary recommended substitute. This Texas Instruments part maintains identical 4 x 2:1 circuit configuration and 1 independent circuit topology. It carries Active product status with 1427 units in inventory. The voltage supply range expands to 2.3V ~ 3.6V, providing broader compatibility. Operating temperature range is -40°C ~ 85°C, which is narrower than the original but suitable for most industrial applications. All compliance certifications (ROHS3, MSL 1, REACH Unaffected) match the original specification.

SN74CB3Q3257PW offers identical functional configuration with significantly higher inventory (210100 units) but carries Last Time Buy status, indicating limited future availability.

Alternative Configuration Options (4 x 1:2 Configuration):

SN74CBTLV3257PWR provides the highest inventory availability (35100 units) with Active product status. This part implements a 4 x 1:2 configuration with 4 independent circuits, requiring circuit board redesign for pin-level compatibility. Voltage and temperature specifications match SN74CB3Q3257PWR. This option is suitable when design flexibility permits functional topology modification.

74CBTLV3257PGG (Renesas Electronics) offers an alternative 4 x 1:2 configuration with Active status and 1220 units available. Specifications align with other 74CBTLV series parts.

Discontinued Parts:

74CBTLV3257PWRG4 and SN74CB3Q3257PWRG4 carry Discontinued at DiGi Electronics status and should not be selected for new designs despite available inventory.

Frequently Asked Questions (FAQ)

Q: Can I use a 4 x 1:2 configuration part as a direct replacement for the 4 x 2:1 PI3B3257LE-2017?

A: No. The 4 x 1:2 configuration (such as SN74CBTLV3257PWR) has different pin assignments and functional topology with 4 independent circuits versus the original's 1 independent circuit. Circuit board redesign is required for electrical compatibility.

Q: What is the voltage supply compatibility between the original and substitute parts?

A: The PI3B3257LE-2017 operates at 3V ~ 3.6V. Most substitute parts (SN74CB3Q3257 series and 74CBTLV series) support 2.3V ~ 3.6V, providing broader voltage compatibility. Designs operating at 3V ~ 3.6V are compatible with all listed substitutes.

Q: Does the operating temperature range difference affect substitution?

A: The original PI3B3257LE-2017 supports -40°C ~ 125°C, while substitute parts support -40°C ~ 85°C. If your application requires operation above 85°C, the original part is necessary. For applications within -40°C ~ 85°C, substitutes are fully compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the original specification. All parts also maintain MSL Rating 1 (Unlimited) and REACH Unaffected status.

Q: Which substitute offers the best long-term availability?

A: SN74CB3Q3257PWR is recommended for new designs. It maintains Active product status with 1427 units in inventory and provides direct 4 x 2:1 functional equivalence. SN74CBTLV3257PWR offers higher inventory (35100 units) but requires circuit redesign due to different configuration.

Q: What packaging options are available for substitutes?

A: All substitute parts use identical 16-TSSOP (0.173", 4.40mm Width) surface mount packaging. Packaging variations exist only in supplier delivery format (Tube, Cut Tape & Digi-Reel), which does not affect electrical or mechanical compatibility.
