CD4072BPWG4 Equivalent & Substitute Parts

Part Overview

The CD4072BPWG4 is a 2-channel OR gate logic integrated circuit manufactured by Texas Instruments, housed in a 14-TSSOP surface mount package. This device operates across a wide supply voltage range of 3V to 18V and is part of the 4000B CMOS logic series. The CD4072BPWG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent substitute components for ongoing design support and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4072BPWG4 is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Logic type (OR Gate)
• Number of circuits (2)
• Number of inputs (4)
• Voltage supply range (3V ~ 18V)
• Quiescent current specification (1 µA maximum)
• Output current capability (3.4mA high and low)
• Input logic level thresholds (Low: 1.5V ~ 4V; High: 3.5V ~ 11V)
• Propagation delay (90ns @ 15V, 50pF)
• Operating temperature range (-55°C ~ 125°C)

Physical Parameters:

• Mounting type (Surface Mount)
• Package type (14-TSSOP)
• Package dimensions (0.173", 4.40mm Width)

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

Substitute parts must match all functional, physical, and compliance parameters without deviation. The CD4072BPW meets these criteria and is identified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The CD4072BPW is the direct substitute for the CD4072BPWG4. Both components are manufactured by Texas Instruments and share identical electrical specifications, operating parameters, and physical packaging. The primary distinction is product status: the CD4072BPWG4 is discontinued, while the CD4072BPW maintains active status with higher inventory availability (8012 pieces in stock versus 1023 pieces for the main part).

Both parts maintain ROHS3 compliance and carry identical moisture sensitivity ratings. The CD4072BPW is suitable for direct replacement in all applications where the CD4072BPWG4 was specified, with no circuit modifications or design changes required.

Frequently Asked Questions (FAQ)

Q: Can the CD4072BPW be used as a direct replacement for the CD4072BPWG4?

A: Yes. The CD4072BPW is electrically and mechanically identical to the CD4072BPWG4. All functional parameters, supply voltage range, output current specifications, propagation delay, operating temperature range, and package dimensions are equivalent. No circuit redesign is necessary.

Q: What is the difference between CD4072BPWG4 and CD4072BPW?

A: The parts are functionally identical. The difference lies in product status: CD4072BPWG4 is discontinued at DiGi Electronics, while CD4072BPW is active. The CD4072BPW also has higher inventory availability.

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

A: Yes. Both components use the 14-TSSOP surface mount package with identical pin configuration and dimensions (0.173", 4.40mm Width). PCB layouts designed for either part are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CD4072BPWG4 and CD4072BPW are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both are REACH unaffected and carry the same ECCN classification.

Q: What is the operating voltage range for these parts?

A: Both parts operate across a supply voltage range of 3V to 18V, providing flexibility for use in low-voltage and standard logic applications.

Q: What is the maximum propagation delay specification?

A: Both parts specify a maximum propagation delay of 90 nanoseconds at 15V supply voltage with a 50pF load capacitance.
