CD4047BPW Equivalent & Substitute Parts

Part Overview

The CD4047BPW is a monostable multivibrator logic integrated circuit manufactured by Texas Instruments, part of the 4000B CMOS logic series. This device operates across a wide supply voltage range of 3V to 18V with a propagation delay of 80 nanoseconds and is housed in a 14-TSSOP surface mount package.

The CD4047BPW has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4047BPW is determined by strict equivalence across the following critical parameters:

• Base product number (CD4047)
• Logic type (Astable, Monostable operation)
• Independent circuits (1 circuit)
• Propagation delay (80 ns)
• Output current specifications (6.8mA high and low)
• Supply voltage range (3V ~ 18V)
• Operating temperature range (-55°C ~ 125°C)
• Package type (14-TSSOP surface mount)
• Electrical and mechanical pin compatibility

The CD4047BPWR meets all these criteria and is therefore a direct substitute. The difference between these parts lies exclusively in packaging format: the CD4047BPW is supplied in tube packaging, while the CD4047BPWR is supplied in cut tape and Digi-Reel format.

Parameter Comparison

Engineering Selection Recommendations

The CD4047BPWR is the direct substitute for the CD4047BPW. Both parts are manufactured by Texas Instruments with identical electrical specifications, pin configurations, and package dimensions. The CD4047BPWR maintains active product status, ensuring continued availability and supply chain reliability.

Both parts comply with ROHS3 standards and carry REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

The primary distinction is packaging format. The CD4047BPWR is supplied in cut tape and Digi-Reel format, which is standard for high-volume production environments. Selection between these formats depends on procurement requirements and assembly processes rather than electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CD4047BPWR be used as a direct replacement for the CD4047BPW?

A: Yes. The CD4047BPWR is electrically and mechanically identical to the CD4047BPW. Both devices share the same base product number, logic type, propagation delay, output current specifications, supply voltage range, operating temperature range, and 14-TSSOP package configuration. Substitution is valid for all applications.

Q: What is the difference between tube and cut tape packaging?

A: Tube packaging supplies components in plastic tubes, typically used for lower-volume orders or manual assembly. Cut tape and Digi-Reel packaging supplies components on continuous tape, optimized for automated pick-and-place assembly in high-volume production. The components themselves are identical; packaging format affects handling and assembly processes only.

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

A: No. Both the CD4047BPW and CD4047BPWR carry identical ROHS3 compliance, REACH Unaffected status, and MSL rating of 1 (Unlimited). Regulatory and environmental certifications are equivalent.

Q: Why is the CD4047BPW discontinued while the CD4047BPWR remains active?

A: Product discontinuation typically reflects supplier inventory management and market demand patterns. The CD4047BPWR, supplied in cut tape format, aligns with standard production packaging preferences and maintains higher inventory levels. The underlying technology and specifications remain current.

Q: Are pin configurations identical between these parts?

A: Yes. Both parts use the 14-TSSOP package with identical pin assignments, electrical characteristics, and functional behavior. PCB layouts and circuit designs require no modification when substituting between these parts.
