Engineering Selection Recommendations

For new designs and production transitions from the obsolete PI5C3253CLE, the following selection criteria apply:

Active Status Priority: CBT3253APW,118 (Nexperia), SN74CBT3253CPW (Texas Instruments), and SN74CBT3253CPWR (Texas Instruments) are all Active products with full manufacturer support and long-term availability. These are preferred for new designs requiring extended product lifecycle.

Extended Supply Range: The Nexperia CBT3253APW,118 and all Texas Instruments variants (74CBT series) support a wider voltage supply range of 4.5V ~ 5.5V compared to the original 4.75V ~ 5.25V specification. This provides additional design margin in applications with variable supply conditions.

Packaging Considerations: SN74CBT3253CPWR offers Cut Tape and Digi-Reel packaging suitable for automated assembly lines. CBT3253APW,118 provides Tape & Reel format for high-volume production. Both SN74CBT3253CPW and PI5C3253LE are available in Tube packaging for lower-volume requirements.

Last Time Buy Options: PI5C3253LE (Diodes) and SN74CBT3253PW (Texas Instruments) are designated Last Time Buy, indicating limited remaining availability. These are suitable only for legacy system maintenance or short-term production runs.

Frequently Asked Questions (FAQ)

Q: Can I directly replace PI5C3253CLE with any of the listed substitutes?

A: Yes. All listed substitute parts maintain identical circuit configuration (2 x 4:1), package type (16-TSSOP), operating temperature range (-40°C ~ 85°C), and mounting type (Surface Mount). Pin-to-pin compatibility is assured for direct PCB replacement without design modification.

Q: What is the difference between the Diodes and Texas Instruments versions?

A: Both manufacturers provide functionally equivalent 2 x 4:1 Multiplexer/Demultiplexer ICs in 16-TSSOP packages. The primary differences are manufacturer-specific product status, packaging formats, and voltage supply range. Texas Instruments variants support 4.5V ~ 5.5V versus Diodes' 4.75V ~ 5.25V specification.

Q: Why is the voltage supply range different for some substitutes?

A: The Texas Instruments 74CBT series and Nexperia CBT3253 are designed with wider voltage tolerance specifications (4.5V ~ 5.5V) compared to the original Diodes PI5C3253 series (4.75V ~ 5.25V). This wider range is fully compatible with the original specification and provides additional design flexibility.

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

A: For new designs, select from the Active status parts: CBT3253APW,118 (Nexperia), SN74CBT3253CPW (Texas Instruments), or SN74CBT3253CPWR (Texas Instruments). These offer full manufacturer support and guaranteed long-term availability. Choose packaging format based on your assembly process requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant with MSL 1 (Unlimited) rating and REACH Unaffected status, matching the original PI5C3253CLE compliance profile.

Q: What is the difference between SN74CBT3253CPW and SN74CBT3253CPWR?

A: Both are Texas Instruments 74CBT3253 variants with identical electrical specifications. The primary difference is packaging format: SN74CBT3253CPW is supplied in Tube format, while SN74CBT3253CPWR is supplied in Cut Tape and Digi-Reel format suitable for automated pick-and-place assembly.
