CD4017BPW Equivalent & Substitute Parts

Part Overview

The CD4017BPW is a decade counter integrated circuit manufactured by Texas Instruments, belonging to the 4000B logic series. This device functions as a 10-bit counter with asynchronous reset and synchronous timing, capable of counting at rates up to 5.5 MHz. The CD4017BPW is packaged in a 16-TSSOP surface mount configuration and operates across a wide supply voltage range of 3 V to 18 V with an extended temperature range of -55°C to 125°C.

The CD4017BPW has been discontinued at DiGi Electronics, making it necessary to identify equivalent substitute parts for ongoing design requirements and component procurement. Alternative parts within the same product family maintain identical electrical and mechanical specifications while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4017BPW is determined by strict equivalence across the following critical parameters:

• Logic Type: Counter, Decade (1 Element, 10 Bit)
• Electrical Performance: Count Rate 5.5 MHz, Supply Voltage 3 V ~ 18 V
• Thermal Range: Operating Temperature -55°C ~ 125°C (TA)
• Package Specification: 16-TSSOP surface mount configuration
• Compliance: ROHS3 Compliant, REACH Unaffected

Parts meeting all these criteria are classified as direct substitutes. Packaging format variations (Tube versus Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility and represent alternative procurement options for the same base product.

Parameter Comparison

Engineering Selection Recommendations

The CD4017BPWR is a direct functional and mechanical equivalent to the CD4017BPW. Both parts are manufactured by Texas Instruments within the 4000B series and share identical electrical specifications, thermal operating range, and 16-TSSOP package configuration.

The primary distinction between these parts is product status and packaging format. The CD4017BPW is discontinued, while the CD4017BPWR maintains active product status with significantly higher inventory availability (35,100 pieces versus 1,304 pieces). The CD4017BPWR is supplied in Cut Tape and Digi-Reel format, whereas the CD4017BPW is supplied in Tube format. Both packaging formats are suitable for automated assembly processes and do not affect component performance or reliability.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. Selection between these parts should be based on procurement availability and packaging requirements for your assembly process.

Frequently Asked Questions (FAQ)

Q: Can CD4017BPWR be used as a direct replacement for CD4017BPW in existing designs?

A: Yes. The CD4017BPWR is electrically and mechanically equivalent to the CD4017BPW. Both parts feature identical logic functionality, count rate, supply voltage range, operating temperature range, and 16-TSSOP package dimensions. No circuit modifications are required.

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

A: Tube and Cut Tape & Digi-Reel are alternative packaging and delivery formats for the same component. Tube packaging supplies components in plastic tubes, while Cut Tape & Digi-Reel supplies components on continuous tape wound on reels. Both formats are compatible with standard surface mount assembly equipment. Selection depends on your production volume and assembly process requirements.

Q: Are there any compliance or certification differences between CD4017BPW and CD4017BPWR?

A: No. Both parts are ROHS3 compliant and REACH unaffected. They meet identical regulatory and environmental standards.

Q: Why is CD4017BPW discontinued while CD4017BPWR remains active?

A: Product discontinuation decisions are based on market demand and manufacturing strategy. The CD4017BPWR remains in active production with higher inventory levels, making it the recommended choice for new procurement.

Q: What are the key parameters that determine substitution eligibility for decade counter ICs?

A: Substitution eligibility is determined by matching logic type (Counter, Decade), bit configuration (10 Bit), count rate (5.5 MHz), supply voltage range (3 V ~ 18 V), operating temperature range (-55°C ~ 125°C), and package specification (16-TSSOP). All these parameters must match exactly for direct substitution.
