PCA9306DCUTE4 Equivalent & Substitute Parts

Part Overview

The PCA9306DCUTE4 is a bidirectional voltage level translator IC manufactured by Texas Instruments, designed for logic-level conversion between 1.2 V to 3.3 V (VCCA) and 1.8 V to 5.5 V (VCCB) domains. This device features auto-direction sensing and operates across an industrial temperature range of -40°C to 105°C. The part is classified as Obsolete, making identification of active equivalent alternatives essential for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution for the PCA9306DCUTE4 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

All substitute parts must maintain identical specifications for:

Translator type (Voltage Level)
Channel configuration (Bidirectional, 1 circuit, 2 channels)
Voltage operating ranges (VCCA: 1.2 V ~ 3.3 V; VCCB: 1.8 V ~ 5.5 V)
Output type (Open Drain, Push-Pull)
Auto-direction sensing feature
Operating temperature range (-40°C ~ 105°C)
Package type (8-VFSOP)
Compliance certifications (ROHS3, REACH Unaffected)

The three identified substitutes—PCA9306DCUR, PCA9306DCURG4, and PCA9306DCUT—meet all these criteria and differ only in packaging format (Cut Tape & Digi-Reel) and product status.

Engineering Selection Recommendations

For new designs and production applications, PCA9306DCUR and PCA9306DCUT are the preferred selections due to their Active product status. Both parts maintain full electrical and mechanical equivalence to the obsolete PCA9306DCUTE4 while ensuring long-term availability and manufacturer support.

PCA9306DCUR is supplied in Cut Tape and Digi-Reel packaging formats with 65,100 units in stock, providing optimal availability for high-volume production requirements.

PCA9306DCUT is supplied in Cut Tape and Digi-Reel packaging with 1,460 units in stock, suitable for standard production volumes.

PCA9306DCURG4 remains available with 17,100 units in stock but carries Obsolete status; selection of this part should be limited to applications requiring existing inventory compatibility or legacy system maintenance.

All three substitute parts maintain ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can PCA9306DCUR directly replace PCA9306DCUTE4 in existing designs?

A: Yes. PCA9306DCUR is a parametric equivalent with identical electrical specifications, voltage ranges, channel configuration, and package type. The only difference is packaging format (Cut Tape & Digi-Reel versus the original format) and Active product status.

Q: What is the difference between PCA9306DCUR and PCA9306DCUT?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in packaging format and inventory availability. PCA9306DCUR has significantly higher stock levels (65,100 units) compared to PCA9306DCUT (1,460 units).

Q: Why is PCA9306DCUTE4 listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this specific part number variant. Active equivalent alternatives (PCA9306DCUR and PCA9306DCUT) are available to support ongoing applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PCA9306DCUR, PCA9306DCURG4, and PCA9306DCUT are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental regulations.

Q: Can these parts operate in the same temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -40°C to 105°C (TA), ensuring thermal compatibility in industrial and commercial applications.

Q: What packaging formats are available for substitutes?

A: All substitute parts are supplied in Cut Tape (CT) and Digi-Reel packaging formats, standard for high-volume production and automated assembly processes.
