PCA9306DCTRG4 Equivalent & Substitute Parts

Part Overview

The PCA9306DCTRG4 is a bidirectional voltage level translator IC from 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 substitutes essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PCA9306DCTRG4 is determined by strict equivalence across the following critical parameters:

• Translator type: Voltage level translation
• Channel configuration: Bidirectional, 1 circuit with 2 channels
• Voltage specifications: VCCA 1.2 V ~ 3.3 V and VCCB 1.8 V ~ 5.5 V
• Output type: Open Drain and Push-Pull capability
• Auto-direction sensing feature
• Operating temperature range: -40°C ~ 105°C
• Package type: 8-LSSOP or 8-MSOP form factor
• Compliance: ROHS3 and MSL Level 1

The identified substitutes PCA9306DCTR and PCA9306DCTT meet all these electrical and mechanical parameters. Both are active products from Texas Instruments, providing continuity for designs currently using the obsolete PCA9306DCTRG4.

Parameter Comparison

Engineering Selection Recommendations

Both PCA9306DCTR and PCA9306DCTT are direct functional equivalents to the obsolete PCA9306DCTRG4. Selection between these two active alternatives should be based on packaging availability and supply chain considerations:

PCA9306DCTR is supplied in Cut Tape (CT) and Digi-Reel® packaging with 65,400 units in stock.

PCA9306DCTT is supplied in Cut Tape (CT) and Digi-Reel® packaging with 406,489 units in stock.

Both parts maintain identical electrical specifications, temperature performance, and compliance certifications (ROHS3, MSL Level 1). The primary distinction is inventory availability and packaging format. For new designs or production transitions away from the obsolete PCA9306DCTRG4, either substitute provides equivalent performance and reliability.

Frequently Asked Questions (FAQ)

Q: Can PCA9306DCTR or PCA9306DCTT be used as direct replacements for PCA9306DCTRG4?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, voltage ranges, channel configuration, output types, and operating temperature range. All three parts share the same base product number (PCA9306) and package form factor (8-LSSOP, 8-MSOP).

Q: What is the difference between PCA9306DCTR and PCA9306DCTT?

A: Both parts are electrically and mechanically identical. The difference lies in packaging format and inventory levels. PCA9306DCTR is available in Cut Tape and Digi-Reel with 65,400 units in stock, while PCA9306DCTT is available in Cut Tape and Digi-Reel with 406,489 units in stock.

Q: Why is the PCA9306DCTRG4 listed as obsolete?

A: The PCA9306DCTRG4 has been discontinued by Texas Instruments. Active alternatives (PCA9306DCTR and PCA9306DCTT) are available to support existing designs and new production requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts (PCA9306DCTRG4, PCA9306DCTR, and PCA9306DCTT) are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (Unlimited moisture sensitivity).

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. All three parts use the same 8-LSSOP or 8-MSOP package footprint (0.110", 2.80mm width) and are pin-compatible. No PCB redesign is required when substituting between these parts.
