CD4068BPW Equivalent & Substitute Parts

Part Overview

The CD4068BPW is an 8-input NAND/AND gate logic integrated circuit manufactured by Texas Instruments in the 4000B series. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The CD4068BPW is packaged in 14-TSSOP surface mount configuration and operates across a wide supply voltage range of 3V to 18V, making it suitable for both legacy and modern digital logic applications. Finding equivalent substitute parts is necessary due to the Last Time Buy status and finite stock levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4068BPW is determined by strict equivalence across the following critical parameters:

• Logic function: NAND/AND gate with identical circuit configuration (1 circuit, 8 inputs)
• Electrical performance: Output current (6.8mA high/low), supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C)
• Physical compatibility: 14-TSSOP package with 0.173" width and surface mount capability
• Regulatory compliance: ROHS3 compliance, REACH unaffected status, and MSL rating

The CD4068BPWR qualifies as a direct substitute based on identical electrical specifications and package geometry. The primary difference is packaging format: the CD4068BPW is supplied in Tube packaging, while the CD4068BPWR is supplied in Tape & Reel (TR) format. Both parts share the same base product number (CD4068) and series designation (4000B).

Parameter Comparison

Engineering Selection Recommendations

The CD4068BPWR is a direct functional and electrical equivalent to the CD4068BPW. Selection between these parts should be based on the following factors:

Inventory and Availability: The CD4068BPW is designated Last Time Buy with 2470 units in stock, while the CD4068BPWR maintains Active product status with 1118 units available. For long-term production requirements, the CD4068BPWR is the preferred choice due to its active status and continued availability.

Packaging Considerations: The CD4068BPW is supplied in Tube packaging, suitable for manual assembly or small-batch operations. The CD4068BPWR is supplied in Tape & Reel format, optimized for automated pick-and-place assembly processes. Selection depends on manufacturing process requirements and assembly equipment capabilities.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring equivalent environmental and regulatory standing for applications subject to these standards.

Frequently Asked Questions (FAQ)

Q: Can the CD4068BPWR be used as a direct replacement for the CD4068BPW in existing designs?

A: Yes. The CD4068BPWR is electrically and functionally identical to the CD4068BPW. Both parts share identical logic function, output current specifications, supply voltage range, operating temperature range, and 14-TSSOP package geometry. The only difference is the packaging format (Tube versus Tape & Reel).

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes, typically used for manual assembly or small quantities. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated assembly equipment. Both formats contain the same component with identical electrical performance.

Q: Are there any compatibility issues when switching from CD4068BPW to CD4068BPWR?

A: No compatibility issues exist at the component level. Both parts are pin-compatible with identical pinout, electrical characteristics, and thermal performance. Assembly process compatibility depends on whether your manufacturing equipment supports Tape & Reel format.

Q: Why is the CD4068BPW designated as Last Time Buy?

A: Last Time Buy designation indicates that Texas Instruments has discontinued production of this part number. The CD4068BPWR, with Active status, represents the current production equivalent and should be used for new designs and long-term supply planning.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the CD4068BPW and CD4068BPWR are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory requirements.
