Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4069UBCN is determined by strict equivalence across the following critical parameters:

• Logic Function: Both parts must be 6-channel inverters with single input configuration
• Package Type: Both must use 14-pin DIP form factor with 0.300" (7.62mm) pitch for mechanical compatibility
• Electrical Specifications: Supply voltage range, quiescent current, output current, propagation delay, and operating temperature must be equal or superior
• Series Classification: Both parts belong to the 4000B CMOS logic family

The CD4069UBE from Texas Instruments meets all substitution criteria as an active product within the same 4000B series, offering identical functional performance with enhanced supply voltage tolerance (3V ~ 18V versus 3V ~ 15V).

Parameter Comparison

Engineering Selection Recommendations

The CD4069UBE is a direct functional equivalent to the CD4069UBCN. Selection of the Texas Instruments variant is supported by the following factors:

• Product Status: The CD4069UBE maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance: The CD4069UBE is RoHS3 compliant, meeting current environmental and regulatory requirements
• Electrical Performance: The CD4069UBE provides superior supply voltage tolerance (18V maximum versus 15V), offering additional design margin in applications operating near the upper voltage boundary
• Mechanical Compatibility: Both parts share identical 14-DIP packaging, enabling direct socket substitution without PCB modification

Frequently Asked Questions (FAQ)

Q: Can the CD4069UBE replace the CD4069UBCN in existing designs?

A: Yes. Both parts are 6-channel inverters in the 4000B series with identical pin configuration, package dimensions, and core electrical specifications. Direct substitution is supported without circuit modification.

Q: What is the difference in supply voltage range between these parts?

A: The CD4069UBCN operates from 3V to 15V, while the CD4069UBE operates from 3V to 18V. The CD4069UBE provides extended upper voltage tolerance, making it suitable for applications requiring higher supply voltages.

Q: Are there packaging differences between these parts?

A: Both parts use 14-pin DIP packaging with 0.300" (7.62mm) pitch. The CD4069UBCN is supplied in standard packaging, while the CD4069UBE is supplied in tube packaging. Both are mechanically compatible for through-hole PCB assembly.

Q: Why is the CD4069UBCN listed as obsolete?

A: The CD4069UBCN has been discontinued by onsemi. The CD4069UBE from Texas Instruments remains in active production and serves as the recommended replacement for new designs and production continuity.

Q: Are there any compliance or certification differences?

A: The CD4069UBE is RoHS3 compliant. Both parts are REACH unaffected and carry EAR99 export classification. The CD4069UBE meets current environmental standards for new component procurement.
