CD4009UBPW Equivalent & Substitute Parts

Part Overview

The CD4009UBPW is a 6-channel inverter logic IC manufactured by Texas Instruments in the 4000B series. This component is classified as obsolete, which necessitates identification of active equivalent parts for continued system design and procurement. The CD4009UBPW operates across a wide supply voltage range of 3V to 18V and is housed in a 16-TSSOP surface mount package. Obsolete status requires engineers to transition to functionally equivalent active alternatives to ensure long-term component availability and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4009UBPW is determined by strict equivalence across the following critical parameters:

• Logic type and circuit configuration (6-channel inverter, single input per channel)
• Electrical specifications (supply voltage range 3V–18V, quiescent current 4 µA maximum, output current ratings 1.5mA/24mA, input logic levels, propagation delay)
• Physical package (16-TSSOP surface mount)
• Environmental and compliance certifications (ROHS3, MSL 1, REACH unaffected)

The CD4009UBPWR is identified as the manufacturer-recommended substitute. Both parts share identical electrical characteristics, logic configuration, and package specifications. The primary distinction is product status and packaging format: CD4009UBPW is obsolete with bulk packaging, while CD4009UBPWR is active with tape and reel (TR) packaging.

Parameter Comparison

Engineering Selection Recommendations

The CD4009UBPWR is the direct equivalent for the obsolete CD4009UBPW. Both components are manufactured by Texas Instruments and maintain identical electrical performance, logic configuration, and physical package specifications. The CD4009UBPWR carries active product status, ensuring ongoing availability and supply chain support. Both parts meet ROHS3 compliance and carry MSL 1 rating, confirming equivalent environmental and regulatory standing. Selection of the CD4009UBPWR eliminates obsolescence risk while preserving full functional and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can CD4009UBPWR be used as a direct replacement for CD4009UBPW in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The CD4009UBPWR is the active equivalent with identical supply voltage range (3V–18V), logic configuration (6-channel inverter), output current ratings (1.5mA/24mA), propagation delay (60ns @ 15V, 50pF), and 16-TSSOP package. No circuit modifications are required.

Q: What is the difference between CD4009UBPW and CD4009UBPWR?

A: The primary differences are product status and packaging format. CD4009UBPW is obsolete with bulk packaging, while CD4009UBPWR is active with tape and reel (TR) packaging. All electrical and mechanical specifications are identical.

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

A: No. Both parts are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity level), and are REACH unaffected. Regulatory and environmental certifications are equivalent.

Q: Is the 16-TSSOP package identical between both parts?

A: Yes. Both parts use the same 16-TSSOP surface mount package with 0.173" width and 4.40mm dimensions. PCB footprints and assembly processes are identical.

Q: Why should I transition from CD4009UBPW to CD4009UBPWR?

A: CD4009UBPW is obsolete, creating long-term procurement and supply chain risk. CD4009UBPWR is active and maintains full manufacturer support, ensuring continued availability and technical support for new designs and production runs.
