CD4025BPWR NOR Gate IC Equivalent & Substitute Parts

Part Overview

The CD4025BPWR is a NOR Gate IC featuring 3 channels with 3 inputs per channel in a 14-TSSOP surface mount package, manufactured by Texas Instruments as part of the 4000B logic series. This device operates across a wide supply voltage range of 3V to 18V and is designed for general-purpose logic applications requiring NOR gate functionality.

The CD4025BPWR carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Substitute Part Grouping Explanation

Substitution of the CD4025BPWR is determined by strict equivalence across the following critical parameters:

Logic Type: NOR Gate with identical 3-channel, 3-input configuration
Electrical Specifications: Matching supply voltage range (3V ~ 18V), quiescent current (1 µA max), output current (3.4mA), input logic levels, and propagation delay characteristics
Package Compatibility: 14-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
Environmental Compliance: ROHS3 compliance and MSL rating of 1 (Unlimited)
Thermal Range: Operating temperature range of -55°C ~ 125°C

The CD4025BPW substitute part maintains full electrical and mechanical equivalence to the CD4025BPWR across all specified parameters. The primary distinction is packaging format: the substitute is supplied in Tube packaging rather than Tape & Reel (TR).

Engineering Selection Recommendations

The CD4025BPW is a direct functional equivalent to the CD4025BPWR. Both parts are manufactured by Texas Instruments and share identical electrical characteristics, logic functionality, and physical package specifications.

The CD4025BPWR is classified as Obsolete, while the CD4025BPW maintains Active product status. For new designs or ongoing production requiring NOR gate logic with the specified electrical and thermal parameters, the CD4025BPW is the appropriate selection.

Both parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards. The distinction between Tape & Reel and Tube packaging is a logistics consideration that does not affect electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can CD4025BPW be used as a direct replacement for CD4025BPWR in existing designs?

A: Yes. The CD4025BPW is electrically and mechanically equivalent to the CD4025BPWR. All electrical parameters, logic functionality, operating temperature range, and package dimensions are identical. The parts are pin-compatible and functionally interchangeable.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel (TR) and Tube are different packaging and delivery formats. Tape & Reel is used for automated assembly processes, while Tube packaging is used for manual handling or lower-volume applications. Both formats contain the same component with identical electrical specifications. The choice between them depends on manufacturing process requirements, not component performance.

Q: Why is the CD4025BPWR marked as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this specific part number. The CD4025BPW, which is functionally identical, remains in Active production status and is the recommended alternative for continued supply.

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

A: No. Both the CD4025BPWR and CD4025BPW maintain identical ROHS3 compliance and MSL rating of 1 (Unlimited). There are no differences in environmental or regulatory compliance.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in logic type (NOR Gate, 3-channel, 3-input), supply voltage range (3V ~ 18V), quiescent current (1 µA max), output current (3.4mA), input logic levels, propagation delay (90ns @ 15V, 50pF), operating temperature range (-55°C ~ 125°C), and 14-TSSOP package dimensions. All these parameters are identical between the main part and substitute.
