CD4017BF Equivalent & Substitute Parts

Part Overview

The CD4017BF is a decade counter integrated circuit manufactured by Texas Instruments, classified as a logic counter component. This IC functions as a 10-bit positive/negative edge-triggered counter with asynchronous reset capability and synchronous timing operation. The CD4017BF is currently in active product status with 1258 units available in new original inventory.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of the decade counter category. The CD4017BE represents an alternative source option with comparable core specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4017BF is determined by the following core parameters:

Functional Parameters (Must Match):

• Logic Type: Counter, Decade
• Number of Elements: 1
• Number of Bits per Element: 10
• Direction: Up
• Reset Type: Asynchronous
• Timing: Synchronous
• Trigger Type: Positive, Negative
• Voltage Supply Range: 3 V ~ 18 V
• Operating Temperature Range: -55°C ~ 125°C (TA)

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package Type: 16-pin DIP configuration (0.300", 7.62mm pitch)
• Series: 4000B

The CD4017BE qualifies as a substitute part because it maintains identical functional specifications and compatible package geometry within the 16-pin DIP family. Both parts operate within the same voltage and temperature ranges and provide equivalent decade counter functionality.

Engineering Selection Recommendations

CD4017BF (Primary Selection): The CD4017BF is the recommended selection for new designs and active production environments. This part maintains active product status from Texas Instruments, ensuring long-term availability and supply chain stability. The CD4017BF is ROHS3 compliant, meeting current environmental and regulatory requirements for commercial and industrial applications. The specified count rate of 11 MHz provides operational margin for timing-critical applications within the decade counter category.

CD4017BE (Alternative Selection): The CD4017BE is classified as obsolete and carries RoHS non-compliance status. This part is suitable only for legacy system maintenance, repair, or replacement scenarios where the original design specification explicitly requires the Harris Corporation variant. The reduced count rate of 5.5 MHz indicates lower maximum operational frequency compared to the CD4017BF. New design implementations should not incorporate the CD4017BE due to product discontinuation and regulatory non-compliance.

Frequently Asked Questions (FAQ)

Q: Can the CD4017BE be used as a direct replacement for the CD4017BF in new designs?

A: No. While both parts share identical functional parameters and package compatibility, the CD4017BE is obsolete and RoHS non-compliant. New designs must use the CD4017BF to ensure regulatory compliance and supply chain continuity.

Q: Are the 16-CDIP and 16-DIP packages mechanically interchangeable?

A: Yes. Both packages maintain 0.300" (7.62mm) pitch and 16-pin through-hole configuration, providing mechanical compatibility for PCB footprints designed for standard 16-pin DIP geometry.

Q: What is the significance of the count rate difference between CD4017BF (11 MHz) and CD4017BE (5.5 MHz)?

A: The count rate specifies the maximum frequency at which the counter can reliably process input clock signals. The CD4017BF supports twice the maximum frequency of the CD4017BE. Applications requiring clock frequencies above 5.5 MHz must use the CD4017BF.

Q: Is the CD4017BE available for procurement?

A: The CD4017BE is classified as obsolete. While legacy inventory may exist through secondary distributors, primary manufacturers no longer produce this part. The CD4017BF is the current production equivalent with active inventory support.

Q: Do both parts require identical PCB layout and circuit design considerations?

A: Yes. Both the CD4017BF and CD4017BE operate within the same voltage supply range (3 V ~ 18 V), temperature range (-55°C ~ 125°C), and provide identical functional logic. Circuit designs are directly transferable between parts, subject to the count rate limitations noted above.
