CD4020BNSRG4 Equivalent & Substitute Parts

Part Overview

The CD4020BNSRG4 is a 14-bit binary counter IC manufactured by Texas Instruments, part of the 4000B logic series. This surface-mount component operates across a wide supply voltage range (3V to 18V) and supports count rates up to 24 MHz with negative edge triggering. The device features asynchronous reset and is housed in a 16-SOIC package.

The CD4020BNSRG4 is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Identifying compatible alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4020BNSRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Binary Counter
• Number of Bits per Element: 14 Bit
• Trigger Type: Negative Edge
• Reset: Asynchronous
• Count Rate: 24 MHz
• Voltage - Supply: 3 V ~ 18 V
• Operating Temperature: -55°C ~ 125°C
• Package / Case: 16-SOIC (0.209", 5.30mm Width)

The CD4020BNSR meets all these criteria and is classified as a parametric equivalent. Both parts share the same base product number (CD4020) and are manufactured by Texas Instruments within the 4000B series. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The CD4020BNSR is a direct parametric equivalent to the CD4020BNSRG4 and is suitable for substitution in all applications requiring a 14-bit binary counter with the specified electrical and mechanical characteristics.

The CD4020BNSR maintains active product status with Texas Instruments, ensuring ongoing availability and supply chain stability. Both parts carry identical compliance certifications: ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1).

The primary advantage of selecting the CD4020BNSR is its active product status and availability in multiple packaging formats (Cut Tape and Digi-Reel), providing flexibility for different procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the CD4020BNSR be used as a direct replacement for the CD4020BNSRG4?

A: Yes. Both parts are parametrically equivalent across all critical specifications: 14-bit binary counter functionality, 24 MHz count rate, negative edge triggering, asynchronous reset, 3V to 18V supply voltage range, -55°C to 125°C operating temperature, and 16-SOIC package. Pin-for-pin compatibility is maintained.

Q: What is the difference between the CD4020BNSRG4 and CD4020BNSR?

A: The primary differences are product status and packaging format. The CD4020BNSRG4 is discontinued and supplied in Digi-Reel format. The CD4020BNSR is an active product available in both Cut Tape and Digi-Reel packaging options.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Regulatory and environmental compliance is equivalent.

Q: Does the packaging format affect electrical performance?

A: No. The packaging format (Cut Tape versus Digi-Reel) affects only procurement and assembly logistics. The electrical and mechanical specifications of the component itself remain identical.

Q: What supply voltage range does this counter support?

A: Both the CD4020BNSRG4 and CD4020BNSR operate across a supply voltage range of 3V to 18V, providing flexibility for various system voltage requirements.

Q: What is the maximum count rate for these devices?

A: Both parts support a maximum count rate of 24 MHz with negative edge triggering.
