CD4072BE-NG Equivalent & Substitute Parts

Part Overview

The CD4072BE-NG is a 2-channel OR gate logic integrated circuit manufactured by Texas Instruments, housed in a 14-pin DIP package. This component is classified as obsolete, indicating that direct procurement of this exact part number may face availability constraints. The CD4072BE-NG belongs to the 4000B CMOS logic series and operates across a wide supply voltage range of 3V to 18V, making it suitable for diverse digital logic applications requiring OR gate functionality.

Identifying equivalent and substitute parts is necessary due to the obsolete status of the CD4072BE-NG. Alternative part numbers with active product status and improved electrical characteristics provide reliable sourcing options while maintaining functional compatibility within system designs.

Substitute Part Grouping Explanation

Substitute parts for the CD4072BE-NG are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Primary Matching Parameters:

• Logic Type: OR Gate (2 channels, 4 inputs per channel)
• Supply Voltage Range: 3V ~ 18V
• Operating Temperature Range: -55°C ~ 125°C
• Max Propagation Delay: 90ns @ 15V, 50pF
• Mounting Type: Through Hole
• Package Type: 14-DIP form factor

Substitution Categories:

1. MFR Recommended Substitute (CD4072BE): Active product status with identical logic configuration and electrical specifications. Differs in quiescent current (1 µA vs. 5 µA) and output current ratings (3.4mA vs. 6.8mA), representing improved power efficiency characteristics while maintaining functional compatibility.

2. Parametric Equivalent (CD4072BF/3): Manufactured by Harris Corporation. Matches all critical electrical parameters including quiescent current (5 µA) and output current (6.8mA). Package variant is 14-CERDIP instead of 14-PDIP, maintaining 14-DIP form factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

CD4072BE (Texas Instruments): This part is the primary recommended substitute for the obsolete CD4072BE-NG. It maintains active product status with full ROHS3 compliance and identical functional specifications. The improved quiescent current (1 µA vs. 5 µA) and reduced output current (3.4mA vs. 6.8mA) represent enhanced power efficiency characteristics. This part is suitable for new designs and replacement applications where power consumption optimization is beneficial.

CD4072BF/3 (Harris Corporation): This parametric equivalent provides an alternative sourcing option with active product status. Electrical characteristics match the original CD4072BE-NG exactly, including quiescent and output current ratings. The 14-CERDIP package variant maintains mechanical compatibility with 14-DIP footprints. RoHS compliance status is not applicable for this part. Selection of this substitute is appropriate when Harris Corporation sourcing is preferred or when specific quiescent current characteristics matching the original part are required.

Compliance Considerations: Both substitute parts maintain the 14-DIP form factor and through-hole mounting type, ensuring direct PCB compatibility. The CD4072BE offers superior compliance documentation with ROHS3 certification and REACH unaffected status, making it the preferred choice for applications with strict regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can CD4072BE be used as a direct replacement for CD4072BE-NG?

A: Yes. The CD4072BE is functionally and mechanically compatible with the CD4072BE-NG. Both parts share identical logic configuration (2-channel OR gate with 4 inputs), supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and 14-DIP package form factor. The CD4072BE is the active product variant with improved power characteristics.

Q: What is the difference between CD4072BE and CD4072BF/3?

A: Both parts are functionally equivalent OR gate ICs with identical logic specifications. The primary differences are manufacturer (Texas Instruments vs. Harris Corporation), quiescent current (1 µA vs. 5 µA), output current (3.4mA vs. 3.4mA vs. 6.8mA), and package variant (14-PDIP vs. 14-CERDIP). Both maintain 14-DIP form factor compatibility.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts (CD4072BE-NG, CD4072BE, and CD4072BF/3) use 14-DIP package form factors with 0.300" (7.62mm) spacing. The 14-PDIP and 14-CERDIP variants are mechanically interchangeable on standard through-hole PCB layouts.

Q: Which substitute part should be selected for new designs?

A: The CD4072BE is recommended for new designs. It offers active product status, full ROHS3 compliance, improved power efficiency (1 µA quiescent current), and comprehensive regulatory documentation including REACH unaffected status.

Q: Does the reduced output current of CD4072BE affect circuit performance?

A: The CD4072BE provides 3.4mA output current compared to 6.8mA in the CD4072BE-NG. This reduction does not affect logic functionality or propagation delay (both 90ns @ 15V, 50pF). Output current capacity should be evaluated based on specific load requirements in the application circuit.

Q: What is the significance of the obsolete status of CD4072BE-NG?

A: Obsolete status indicates that Texas Instruments has discontinued production and support for this specific part number. The CD4072BE represents the active replacement, ensuring continued availability and manufacturer support for future procurement needs.
