Substitute Part Grouping Explanation

Substitution of the CD4015BCN is determined by strict equivalence across the following critical parameters:

• Logic Type: Shift Register (2 elements, 4 bits per element)
• Function: Serial to Parallel conversion
• Voltage Supply Range: 3V ~ 18V
• Operating Temperature Range: -55°C ~ 125°C
• Package Configuration: 16-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Base Product Number: CD4015

The CD4015BE from Texas Instruments meets all these criteria and is classified as an active product, providing functional and electrical equivalence to the obsolete CD4015BCN.

Parameter Comparison

Engineering Selection Recommendations
