CD4007UBPW Equivalent & Substitute Parts

Part Overview

The CD4007UBPW is a Complementary Pair Plus Inverter logic IC manufactured by Texas Instruments in the 4000B series. This device integrates dual complementary transistor pairs with an inverter function in a 14-TSSOP surface mount package. The CD4007UBPW is designated as Last Time Buy, indicating end-of-life status. Identifying equivalent substitute parts is necessary to ensure continued design support, maintain supply chain continuity, and facilitate procurement for new production runs or design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4007UBPW is determined by strict equivalence across the following critical parameters:

• Logic Function: Complementary Pair Plus Inverter architecture must be identical
• Electrical Specifications: Supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and bit configuration (3 bits) must match exactly
• Package Compatibility: 14-TSSOP surface mount package with identical pinout and physical dimensions (0.173", 4.40mm Width)
• Compliance Standards: RoHS3 compliance, MSL Level 1, and REACH unaffected status must be maintained

The CD4007UBPWR qualifies as a direct substitute based on identical electrical and functional specifications. The only difference is packaging format: the substitute uses Tape & Reel (TR) packaging instead of Tube packaging, which does not affect electrical performance or pinout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CD4007UBPWR is the direct equivalent substitute for the CD4007UBPW. Both parts are manufactured by Texas Instruments with identical electrical specifications, functional architecture, and physical package dimensions. The CD4007UBPWR maintains Active product status, ensuring continued availability and supply chain support compared to the Last Time Buy status of the original part.

Selection between these parts should be based on procurement requirements: the CD4007UBPW in Tube packaging is suitable for lower-volume or prototype applications, while the CD4007UBPWR in Tape & Reel format is optimized for high-volume automated assembly processes. Both parts satisfy identical compliance requirements (ROHS3, MSL Level 1, REACH unaffected) and are suitable for applications requiring the 3V to 18V supply voltage range and -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the CD4007UBPWR be used as a direct replacement for the CD4007UBPW in existing designs?

A: Yes. The CD4007UBPWR is electrically and functionally identical to the CD4007UBPW. Both parts have the same pinout, package dimensions (14-TSSOP), and electrical specifications. The only difference is the packaging format (Tape & Reel versus Tube), which does not affect circuit performance or board-level compatibility.

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

A: Tube packaging is used for lower-volume orders and manual assembly processes, while Tape & Reel packaging is designed for high-volume automated pick-and-place assembly. Both formats contain the same component with identical electrical properties and pinout. The choice depends on manufacturing volume and assembly equipment capabilities.

Q: Why is the CD4007UBPW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this specific packaging variant. The CD4007UBPWR in Tape & Reel format remains in Active production status, making it the recommended choice for new designs and ongoing production requirements.

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

A: No. Both the CD4007UBPW and CD4007UBPWR maintain identical compliance certifications: ROHS3 compliance, MSL Level 1 (Unlimited), REACH unaffected status, and EAR99 export classification. Both parts are suitable for applications with identical regulatory requirements.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: identical logic function (Complementary Pair Plus Inverter), matching supply voltage range (3V ~ 18V), identical operating temperature range (-55°C ~ 125°C), same package type (14-TSSOP), and equivalent compliance certifications. All these parameters are identical between the CD4007UBPW and CD4007UBPWR.
