Substitute Part Grouping Explanation

Substitute parts for the CD4020BCN are classified based on strict parameter alignment within the 4000B CMOS logic series:

Direct Manufacturer Substitute (CD4020BE): Shares identical functional specifications including 14-bit binary counter architecture, negative-edge trigger, asynchronous reset, and 16-DIP package. Differs in maximum count rate (24 MHz vs. 12 MHz) and supply voltage range (3 V ~ 18 V vs. 3 V ~ 15 V), both representing enhanced performance specifications. Manufactured by Texas Instruments with active product status.

Parametric Equivalent (CD4060BE): Maintains core counter functionality with matching 14-bit resolution, negative-edge trigger, asynchronous reset, and 16-DIP package. Operates at identical 12 MHz count rate and shares 3 V ~ 18 V supply voltage range. Manufactured by Texas Instruments with active product status. Base product number differs (CD4060 vs. CD4020), indicating internal architectural variation while preserving functional equivalence for standard counting applications.

Parameter Comparison

Engineering Selection Recommendations

CD4020BE (Texas Instruments): Recommended as the primary direct substitute. Active product status ensures long-term availability and supply chain continuity. Enhanced specifications (24 MHz count rate, 3 V ~ 18 V supply range) provide operational margin beyond original CD4020BCN requirements. RoHS3 compliance supports modern manufacturing standards. Identical package and pinout enable direct board-level replacement without layout modification.

CD4060BE (Texas Instruments): Suitable for applications where 12 MHz count rate matches original design specifications. Active product status and RoHS3 compliance ensure availability and regulatory compliance. Identical package and pinout support direct substitution. Base product number variation (CD4060 vs. CD4020) reflects internal counter configuration differences; functional equivalence is maintained for standard binary counting operations within specified parameters.

Frequently Asked Questions (FAQ)

Q: Can CD4020BE replace CD4020BCN in existing designs? A: Yes. CD4020BE maintains identical pin configuration, package type (16-DIP), and core counter functionality. Enhanced count rate (24 MHz) and supply voltage range (3 V ~ 18 V) are backward compatible with CD4020BCN applications designed for 12 MHz operation and 3 V ~ 15 V supply.

Q: What is the functional difference between CD4020BE and CD4060BE? A: Both devices are 14-bit binary counters with negative-edge trigger and asynchronous reset in 16-DIP packages. CD4020BE supports 24 MHz count rate; CD4060BE operates at 12 MHz. Both support 3 V ~ 18 V supply voltage. Selection depends on circuit timing requirements.

Q: Are package dimensions identical across all three parts? A: Yes. All three parts use 16-DIP (0.300", 7.62mm) through-hole packages with identical pinout, enabling direct board-level substitution without PCB modification.

Q: Why is CD4020BCN listed as obsolete? A: Obsolete status indicates onsemi has discontinued production. Texas Instruments maintains active production of functionally equivalent CD4020BE and CD4060BE alternatives, ensuring design continuity and supply availability.

Q: Do substitute parts meet current compliance requirements? A: Yes. Both CD4020BE and CD4060BE are RoHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.
