Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4019BM is determined by strict equivalence across the following critical parameters:

• Logic Function: AND/OR gate configurable topology with identical circuit count (4) and input configuration (2 inputs per circuit)
• Electrical Specifications: Matching voltage supply range (3V ~ 18V), output current ratings (6.8mA high and low), and operating temperature range (-55°C ~ 125°C)
• Package Compatibility: Identical 16-SOIC surface mount package with 0.154" width (3.90mm)
• Compliance Standards: ROHS3 compliance and MSL rating of 1 (Unlimited)

The CD4019BM96 qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is packaging format: the CD4019BM is supplied in Tube packaging, while the CD4019BM96 is supplied in Tape & Reel (TR) format. Both share the same base product number (CD4019) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The CD4019BM96 is a direct functional and electrical equivalent to the CD4019BM. Both parts maintain identical electrical performance specifications and physical package dimensions. The CD4019BM96 carries Active product status, ensuring continued manufacturer support and availability, whereas the CD4019BM is in Last Time Buy status.

Selection between these parts should be based on packaging requirements and supply chain considerations. The CD4019BM96 in Tape & Reel format is suitable for automated assembly processes and high-volume production environments. Both parts satisfy ROHS3 compliance and REACH requirements, making them suitable for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the CD4019BM96 be used as a direct replacement for the CD4019BM in existing designs?

A: Yes. The CD4019BM96 is electrically and mechanically equivalent. Both parts feature identical logic function, electrical specifications, and 16-SOIC package dimensions. The only difference is the packaging format (Tube versus Tape & Reel).

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

A: Tube packaging is used for manual handling and lower-volume applications, while Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment. The components themselves are identical; only the delivery format differs.

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

A: No. Both the CD4019BM and CD4019BM96 are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). They meet the same regulatory and environmental standards.

Q: Why is the CD4019BM marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The CD4019BM96 remains in Active status and is the recommended alternative for new designs and ongoing production.

Q: Are the electrical characteristics identical between CD4019BM and CD4019BM96?

A: Yes. Both parts operate across the same voltage supply range (3V ~ 18V), support the same operating temperature range (-55°C ~ 125°C), and deliver identical output current specifications (6.8mA high and low). Logic function, circuit count, and input configuration are identical.
