Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4041UBMT is determined by strict equivalence across the following critical parameters:

• Logic type and functional configuration (Buffer, Line Driver with 4 elements, 1 bit per element)
• Output type (Complementary)
• Output current specifications (38mA high and low)
• Supply voltage range (3V ~ 18V)
• Operating temperature range (-55°C ~ 125°C)
• Package type and physical dimensions (14-SOIC, 0.154" width, 3.90mm)
• Mounting type (Surface Mount)
• Compliance certifications (ROHS3, REACH Unaffected)

The CD4041UBM96 meets all these criteria and is classified as a parametric equivalent. The primary difference between these parts is packaging format: the CD4041UBMT is supplied in Tape & Reel (TR) format, while the CD4041UBM96 is supplied in Cut Tape (CT) & Digi-Reel® format.

Parameter Comparison

Engineering Selection Recommendations

The CD4041UBM96 is a direct parametric equivalent to the CD4041UBMT. Both parts share identical electrical specifications, thermal ratings, and compliance certifications. The CD4041UBMT is designated Last Time Buy, while the CD4041UBM96 maintains Active product status, ensuring continued availability. Selection between these parts should be based on packaging requirements: the CD4041UBMT is supplied in standard Tape & Reel format, whereas the CD4041UBM96 is available in Cut Tape and Digi-Reel® formats. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the CD4041UBM96 be used as a direct replacement for the CD4041UBMT?

A: Yes. The CD4041UBM96 is a parametric equivalent with identical electrical characteristics, output specifications, supply voltage range, operating temperature range, and package dimensions. The only difference is the packaging format supplied by the manufacturer.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel is a continuous reel format suitable for high-volume automated assembly. Cut Tape is individual tape segments, and Digi-Reel® is a proprietary reel format. Both formats contain the same die and package; the difference is in supply and handling method. Selection depends on production volume and assembly equipment compatibility.

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

A: No. Both the CD4041UBMT and CD4041UBM96 are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited).

Q: Why is the CD4041UBMT marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The CD4041UBM96, with Active status, is the recommended alternative for continued supply.

Q: Are the physical package dimensions identical?

A: Yes. Both parts use the 14-SOIC package with 0.154" width and 3.90mm dimensions, ensuring identical PCB footprints and assembly compatibility.
