CD4022BCN Equivalent & Substitute Parts

Part Overview

The CD4022BCN is a 4-bit binary counter IC manufactured by onsemi, housed in a 16-DIP package. This device functions as a positive edge-triggered counter with asynchronous reset capability, operating across a wide supply voltage range of 3V to 15V and temperature range of -55°C to 125°C. The CD4022BCN is classified as an obsolete product, making equivalent and substitute parts necessary for ongoing system maintenance, repair, and legacy design support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4022BCN is determined by strict equivalence across the following critical parameters:

• Logic Type: Binary Counter
• Bit Configuration: 4-bit, single element
• Counter Direction: Up
• Trigger Mechanism: Positive Edge
• Reset Type: Asynchronous
• Package Type: 16-DIP (0.300", 7.62mm)
• Mounting: Through Hole
• Series Compatibility: 4000B

The CD4022BE qualifies as a direct substitute based on matching all functional and physical parameters. Variations in supply voltage range (3V–18V for CD4022BE versus 3V–15V for CD4022BCN) and manufacturer origin do not affect functional substitution within standard operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The CD4022BE is a direct functional equivalent to the CD4022BCN. Both devices share identical logic architecture, pin configuration, and operational characteristics within the specified temperature and voltage ranges. The CD4022BE accommodates a slightly higher maximum supply voltage (18V versus 15V), which presents no limitation for applications designed for the CD4022BCN.

Selection between these parts should be based on availability and application requirements. The CD4022BCN is classified as obsolete; the CD4022BE, also obsolete, remains available in limited inventory. Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The CD4022BE is RoHS non-compliant, consistent with the legacy status of both devices.

Frequently Asked Questions (FAQ)

Q: Can the CD4022BE replace the CD4022BCN in existing designs?

A: Yes. The CD4022BE is a direct substitute. Both devices are 4-bit binary counters in 16-DIP packages with identical functional specifications, pin assignments, and operating characteristics.

Q: Are there differences in supply voltage requirements?

A: The CD4022BE supports 3V–18V, while the CD4022BCN supports 3V–15V. This difference does not restrict substitution; applications designed for the CD4022BCN operate within the CD4022BE's voltage range.

Q: Do these parts require different PCB layouts?

A: No. Both parts use the 16-DIP (0.300", 7.62mm) package with identical through-hole mounting. PCB layouts are directly compatible.

Q: What is the significance of the obsolete product status?

A: Both the CD4022BCN and CD4022BE are obsolete products. This status indicates that manufacturers have discontinued production. Substitution between these parts is necessary for maintenance and repair of legacy systems. Inventory availability is limited.

Q: Are there RoHS compliance considerations?

A: The CD4022BE is RoHS non-compliant. If RoHS compliance is required for new designs, alternative modern counter ICs should be evaluated. For legacy system repair, RoHS status does not affect functional compatibility.

Q: Can these parts be used interchangeably in production?

A: Yes, within the constraints of component availability. Both parts meet identical functional and physical specifications. Production decisions should account for inventory status and long-term supply chain considerations.
