Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4093BCN is determined by strict equivalence across the following parameters:

• Logic Type: NAND Gate with identical 4-channel, 2-input configuration
• Schmitt Trigger functionality: Required feature for signal conditioning
• Package compatibility: 14-DIP form factor with 0.300" (7.62mm) pitch
• Supply voltage range: Minimum 3V to 15V overlap required
• Operating temperature range: -55°C to 125°C minimum coverage
• Through-hole mounting: Mechanical compatibility with existing PCB layouts
• Series classification: 4000B logic family

The CD4093BE from Texas Instruments meets all substitution criteria within the 4000B series classification.

Parameter Comparison

Engineering Selection Recommendations

The CD4093BE from Texas Instruments is a direct functional substitute for the CD4093BCN. The Texas Instruments variant offers extended supply voltage range (3V ~ 18V versus 3V ~ 15V), improved propagation delay performance (130ns versus 160ns at 15V, 50pF), and active product status with ROHS3 compliance. Both components share identical logic configuration, package form factor, and operating temperature specifications. The CD4093BE is suitable for applications requiring the CD4093BCN where component availability or compliance requirements necessitate substitution.

Frequently Asked Questions (FAQ)

Q: Can CD4093BE replace CD4093BCN in existing designs? A: Yes. Both components are 4-channel NAND gates with Schmitt Trigger functionality in 14-DIP packages. Electrical parameters are compatible within the specified operating ranges. Direct PCB substitution is possible without circuit modification.

Q: What are the key differences between these parts? A: The CD4093BE offers extended supply voltage range (18V maximum versus 15V), faster propagation delay (130ns versus 160ns), and active product status with ROHS3 compliance. Quiescent current is higher in the CD4093BE (4 µA versus 1 µA). Input logic level thresholds differ slightly but remain compatible for standard logic applications.

Q: Are there packaging differences? A: Both components use 14-DIP (0.300", 7.62mm) through-hole packages. The CD4093BCN is supplied in standard packaging, while the CD4093BE is supplied in tube packaging. Physical dimensions and pin configurations are identical.

Q: Which part should be selected for new designs? A: The CD4093BE is recommended for new designs due to active product status, ROHS3 compliance, and extended supply voltage range. The CD4093BCN is obsolete and should be reserved for legacy system maintenance only.

Q: Are there supply voltage compatibility concerns? A: The CD4093BE operates across 3V to 18V, which encompasses the CD4093BCN operating range of 3V to 15V. Applications designed for the CD4093BCN will function correctly with the CD4093BE within the original voltage specifications.
