PI5C3253LE Equivalent & Substitute Parts

Part Overview

The PI5C3253LE is a 2 x 4:1 Multiplexer/Demultiplexer logic IC manufactured by Diodes Incorporated in a 16-TSSOP surface mount package. This component is classified as Last Time Buy, indicating limited availability from the original manufacturer. Equivalent substitute parts are necessary to ensure design continuity and maintain supply chain reliability for applications requiring this multiplexing functionality.

Substitute Part Grouping Explanation

Substitution of the PI5C3253LE is determined by strict equivalence in the following parameters:

Circuit type and configuration (2 x 4:1 Multiplexer/Demultiplexer)
Package form factor (16-TSSOP with identical 0.173" width and 4.40mm dimensions)
Operating temperature range (-40°C ~ 85°C)
Supply voltage compatibility (single supply operation)
Regulatory compliance (RoHS3, REACH Unaffected, EAR99)
Moisture sensitivity classification (MSL 1)

All substitute parts listed maintain functional and electrical equivalence within these defined parameters. Packaging format variations (Tube, Tape & Reel, Cut Tape) do not affect electrical compatibility but may influence procurement and handling requirements.

Engineering Selection Recommendations

For applications currently using the PI5C3253LE, the following selection criteria apply:

Active Product Status Priority: CBT3253APW,118 (Nexperia), SN74CBT3253CPW (Texas Instruments), and SN74CBT3253CPWR (Texas Instruments) are all classified as Active products, ensuring long-term availability and continued manufacturing support. These are preferred for new designs and ongoing production.

Last Time Buy Consideration: Both PI5C3253LE and SN74CBT3253PW carry Last Time Buy status, indicating limited future availability. These should not be selected for new applications requiring extended production lifecycles.

Voltage Supply Range: Substitute parts from Nexperia and Texas Instruments offer a wider supply voltage range (4.5V ~ 5.5V) compared to the original PI5C3253LE (4.75V ~ 5.25V). This expanded range provides additional design flexibility for applications operating at lower supply voltages.

Packaging and Procurement: Selection between Tube, Tape & Reel, and Cut Tape formats depends on procurement volume and assembly line requirements. All formats maintain identical electrical and mechanical compatibility.

Regulatory Compliance: All listed substitutes maintain equivalent RoHS3 compliance, REACH Unaffected status, and EAR99 classification, ensuring regulatory requirements are met across all substitute options.

Frequently Asked Questions (FAQ)

Q: Can I directly replace PI5C3253LE with any of the listed substitutes without circuit modification?

A: Yes. All listed substitutes maintain identical 2 x 4:1 multiplexer/demultiplexer functionality, 16-TSSOP package pinout, operating temperature range, and regulatory compliance. Direct pin-for-pin replacement is supported.

Q: What is the difference between the Nexperia CBT3253APW,118 and Texas Instruments SN74CBT3253 variants?

A: The functional circuit configuration and package form factor are identical. Differences exist only in manufacturer, product status (Nexperia is Active; some TI variants are Last Time Buy), and packaging format (Tape & Reel vs. Tube vs. Cut Tape). Electrical performance and pinout are equivalent.

Q: Why do substitute parts have a wider voltage supply range (4.5V ~ 5.5V) than the original PI5C3253LE (4.75V ~ 5.25V)?

A: The substitute parts from Nexperia and Texas Instruments are designed with broader supply voltage tolerance specifications. This does not affect compatibility with the original design operating within the PI5C3253LE voltage range; it provides additional flexibility for applications requiring lower supply voltages.

Q: Does packaging format (Tube, Tape & Reel, Cut Tape) affect electrical compatibility?

A: No. Packaging format affects only procurement, storage, and assembly line handling. All packaging formats contain electrically identical components with the same pinout and performance characteristics.

Q: Which substitute should I select for a new design?

A: Select from the Active status products: CBT3253APW,118 (Nexperia), SN74CBT3253CPW (Texas Instruments), or SN74CBT3253CPWR (Texas Instruments). These ensure long-term availability and manufacturing support. Avoid Last Time Buy products for new designs.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes, including the original PI5C3253LE, are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.
