Substitute Part Grouping Explanation

Substitute parts for the CD4027BEE4 are identified based on strict parametric equivalence across electrical and mechanical specifications. The substitution criteria are:

Critical Matching Parameters:

• Flip-flop type: JK Type with Set(Preset) and Reset function
• Output configuration: Complementary outputs
• Number of elements: 2 elements, 1 bit per element
• Clock frequency: 24 MHz maximum
• Propagation delay: 90ns @ 15V, 50pF
• Trigger mechanism: Positive Edge
• Supply voltage range: 3V ~ 18V
• Output current capability: 6.8mA (High and Low)
• Input capacitance: 5 pF
• Operating temperature range: -55°C ~ 125°C
• Package format: 16-DIP (0.300", 7.62mm) Through Hole
• Series designation: 4000B
• Compliance: ROHS3 Compliant, REACH Unaffected

Substitute parts must maintain identical functional behavior, electrical performance, and physical form factor. Variations in quiescent current (Iq) are permissible when all other parameters remain equivalent, as this parameter does not affect core switching functionality or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CD4027BE serves as a direct parametric equivalent to the CD4027BEE4. Both components are manufactured by Texas Instruments within the 4000B logic series and maintain identical electrical specifications across all critical parameters including clock frequency, propagation delay, supply voltage range, output current capability, and operating temperature range.

Both parts carry Active product status, confirming ongoing manufacturing support and availability. Compliance certifications are equivalent: both are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

The CD4027BE exhibits lower quiescent current (4 µA versus 20 µA), which represents an improvement in power efficiency without affecting switching performance or functional compatibility. This characteristic makes the CD4027BE suitable for applications where reduced standby power consumption is beneficial.

Physical form factor and mounting characteristics are identical: both utilize 16-DIP (0.300", 7.62mm) Through Hole packaging, enabling direct socket-level substitution without PCB redesign or mechanical modification.

Selection between these parts should be based on inventory availability and application-specific power consumption requirements. The CD4027BE is preferred when lower quiescent current is advantageous; the CD4027BEE4 remains appropriate for existing designs or when specific part number continuity is required.

Frequently Asked Questions (FAQ)

Q: Can CD4027BE replace CD4027BEE4 in existing circuit designs?

A: Yes. The CD4027BE is a parametric equivalent with identical electrical performance across all critical switching and timing parameters. Direct substitution is supported at the component level without circuit modification.

Q: What is the difference between CD4027BEE4 and CD4027BE?

A: The primary difference is quiescent current: CD4027BEE4 draws 20 µA while CD4027BE draws 4 µA. All other electrical and mechanical parameters are identical. The suffix variation (BEE4 versus BE) reflects different packaging or distribution designations from Texas Instruments, but the core die and functionality remain equivalent.

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both components use identical 16-DIP (0.300", 7.62mm) Through Hole packaging. PCB layouts, socket assignments, and pin configurations are fully compatible without modification.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both CD4027BEE4 and CD4027BE are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations for electronic component manufacturing and distribution.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For new designs where power efficiency is a consideration, CD4027BE is preferred due to its lower quiescent current (4 µA). Both parts are Active status with equivalent availability and support.

Q: What is the maximum clock frequency for both parts?

A: Both parts support 24 MHz maximum clock frequency with 90ns propagation delay at 15V supply with 50pF load.

Q: Are there any temperature or voltage operating differences?

A: No. Both parts operate identically across the full temperature range (-55°C ~ 125°C) and supply voltage range (3V ~ 18V).

Q: Can these parts be used interchangeably in production?

A: Yes. From an engineering and functional perspective, these parts are interchangeable. Procurement decisions may consider inventory levels, lead times, and cost factors, but no technical barriers to substitution exist.
