Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4019BCN is determined by the following critical parameters:

• Logic function: AND/OR gate configurable topology with 4 circuits
• Input configuration: 2 inputs per circuit
• Package form factor: 16-DIP (0.300", 7.62mm) through-hole mounting
• Electrical operating range: Supply voltage and temperature specifications
• Output characteristics: Single-ended output type
• Series classification: 4000B CMOS logic family

The CD4019BE qualifies as a direct substitute based on matching all core functional and physical parameters within the allowed electrical specifications of this product category.

Parameter Comparison

Engineering Selection Recommendations

The CD4019BE (Texas Instruments) is the qualified substitute for the CD4019BCN. Selection of the CD4019BE is supported by the following factors:

• Identical logic function and circuit configuration within the 4000B CMOS family
• Matching package form factor and through-hole mounting compatibility
• Operating temperature range equivalence across -55°C to 125°C
• Extended supply voltage range (3V ~ 18V) that encompasses the original specification (3V ~ 15V)
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance status for applications requiring environmental regulatory adherence

The CD4019BE output current specifications (6.8mA, 6.8mA) differ from the original part (3mA, 10mA) but remain within acceptable parameters for standard logic-level applications in the 4000B series.

Frequently Asked Questions (FAQ)

Q: Can the CD4019BE directly replace the CD4019BCN in existing designs?

A: Yes. Both devices implement identical AND/OR gate logic with 4 circuits and 2 inputs per circuit in the same 16-DIP package. Pin configuration and functional behavior are equivalent. The CD4019BE operates across a wider supply voltage range (3V ~ 18V versus 3V ~ 15V), providing enhanced compatibility with various power supply designs.

Q: What are the differences in output current between these parts?

A: The CD4019BCN specifies 3mA output high and 10mA output low current. The CD4019BE specifies 6.8mA for both output high and low conditions. Both values are within acceptable operating ranges for standard CMOS logic applications. Circuit designs should verify output current requirements for specific load conditions.

Q: Is the CD4019BE suitable for new designs?

A: Yes. The CD4019BE carries active product status and ROHS3 compliance, making it appropriate for new design implementations. The CD4019BCN is obsolete and should not be specified for new applications.

Q: Are there packaging differences between these parts?

A: No. Both the CD4019BCN and CD4019BE use identical 16-DIP (0.300", 7.62mm) through-hole packaging. PCB layout and socket compatibility are equivalent.

Q: What is the temperature operating range for both parts?

A: Both the CD4019BCN and CD4019BE operate across -55°C to 125°C, providing identical thermal performance specifications.
