CD4017BCN Equivalent & Substitute Parts

Part Overview

The CD4017BCN is a decade counter integrated circuit manufactured by onsemi, classified as a Logic Counter component in the 4000B series. This IC functions as a 10-bit positive/negative edge-triggered counter with asynchronous reset and synchronous timing, housed in a 16-pin DIP package. The CD4017BCN is currently listed as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD4017BCN are identified based on strict functional and electrical compatibility criteria. The primary substitution parameters are:

• Logic Type: Counter, Decade (identical function)
• Number of Bits per Element: 10 (identical bit width)
• Number of Elements: 1 (identical element count)
• Direction: Up (identical counting direction)
• Reset: Asynchronous (identical reset behavior)
• Timing: Synchronous (identical timing architecture)
• Trigger Type: Positive, Negative (identical edge triggering)
• Package / Case: 16-DIP (0.300", 7.62mm) (identical physical form factor)
• Mounting Type: Through Hole (identical mounting method)
• Operating Temperature Range: -55°C ~ 125°C (TA) (identical thermal range)
• Series: 4000B (identical logic family)

All identified substitute parts meet these criteria. The CD40174BE is excluded from direct substitution due to functional incompatibility: it is a D-Type Flip Flop with 6-bit configuration, not a decade counter with 10-bit configuration.

Parameter Comparison

Engineering Selection Recommendations

Both CD4017BE (Harris Corporation) and CD4017BEE4 (Texas Instruments) are functionally equivalent substitutes for the CD4017BCN. Selection between these alternatives should be based on the following criteria:

CD4017BE is suitable for applications where RoHS non-compliance is acceptable and where supply chain availability from Harris Corporation sources is established. This part maintains full functional equivalence with identical electrical specifications and package form factor.

CD4017BEE4 is the preferred substitute for applications requiring RoHS3 compliance. This part is manufactured by Texas Instruments and carries ROHS3 Compliant status, making it appropriate for designs subject to environmental and regulatory compliance requirements. The CD4017BEE4 offers identical functional specifications and package compatibility while meeting modern compliance standards.

Both substitutes support the full supply voltage range of 3 V to 18 V, which encompasses the CD4017BCN operating range of 3 V to 15 V, ensuring compatibility in existing circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can CD4017BE or CD4017BEE4 be used as direct pin-for-pin replacements for CD4017BCN?

A: Yes. Both substitute parts are housed in identical 16-DIP (0.300", 7.62mm) through-hole packages with matching pinouts. Direct substitution is possible without PCB modification.

Q: What is the difference between CD4017BE and CD4017BEE4?

A: Both parts are decade counters with identical functional specifications. The primary difference is compliance status: CD4017BEE4 is RoHS3 compliant, while CD4017BE is RoHS non-compliant. CD4017BEE4 is manufactured by Texas Instruments; CD4017BE is manufactured by Harris Corporation.

Q: Are there any voltage supply differences between the main part and substitutes?

A: The CD4017BCN operates at 3 V to 15 V. Both substitutes operate at 3 V to 18 V. This extended upper voltage range in the substitutes is compatible with CD4017BCN designs, as the substitutes will function correctly at any voltage within the CD4017BCN specification range.

Q: Why is CD40174BE not listed as a substitute?

A: CD40174BE is a D-Type Flip Flop with 6-bit configuration, not a decade counter. It does not meet the functional requirements for substitution, as it performs a different logic function and has different bit width and element configuration.

Q: What is the significance of the 4000B series designation?

A: The 4000B series indicates the logic family classification. All identified substitutes belong to the same 4000B series, confirming functional and electrical compatibility within the CMOS logic family standard.

Q: Are there any thermal or operating condition limitations when substituting these parts?

A: No. All parts, including the main CD4017BCN and both substitutes, operate across the identical temperature range of -55°C to 125°C (TA), ensuring equivalent thermal performance in all operating environments.
