Substitute Part Grouping Explanation

Substitution of the CD4022BPW is determined by strict equivalence across the following critical parameters:

• Logic Type: Binary Counter
• Number of Bits per Element: 4 Bit
• Direction: Up
• Trigger Type: Positive Edge
• Reset: Asynchronous
• Count Rate: 6 MHz minimum
• Voltage - Supply: 3 V ~ 18 V
• Package / Case: 16-TSSOP
• Mounting Type: Surface Mount

The CD4022BPWR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between these parts is packaging format: the main part (CD4022BPW) is supplied in Tube packaging, while the substitute (CD4022BPWR) is supplied in Tape & Reel format.

Parameter Comparison

Engineering Selection Recommendations

The CD4022BPWR is a direct electrical and mechanical equivalent to the CD4022BPW. Both parts maintain identical functional specifications, electrical performance, and physical package dimensions. The CD4022BPWR is preferred for new designs and ongoing production due to its Active product status, ensuring long-term availability. Both parts satisfy ROHS3 compliance and REACH requirements, making them suitable for regulated applications. The packaging format difference (Tube versus Tape & Reel) does not affect electrical performance and should be selected based on assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can CD4022BPWR replace CD4022BPW in existing designs?

A: Yes. The CD4022BPWR is electrically and mechanically identical to the CD4022BPW. Both parts feature the same 16-TSSOP package, identical pin configuration, and equivalent electrical specifications. No circuit modifications are required.

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

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-quantity applications. Tape & Reel packaging supplies components on continuous tape wound on reels, optimized for automated assembly processes. Electrical performance is identical; packaging selection depends on assembly methodology and volume requirements.

Q: Why is CD4022BPW marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this specific part number. The CD4022BPWR remains in Active production status, providing continued availability for the same functional device.

Q: Are there any compliance differences between these parts?

A: No. Both CD4022BPW and CD4022BPWR maintain identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 ratings.

Q: What is the maximum count rate for these devices?

A: Both parts support a maximum count rate of 6 MHz, suitable for standard logic timing applications within the specified operating temperature range of -55°C to 125°C.
