CD4054BNSR Equivalent & Substitute Parts

Part Overview

The CD4054BNSR is a 4-segment LCD driver IC manufactured by Texas Instruments in a 16-SO surface mount package. This component is classified as a Power Management (PMIC) device and is used for driving LCD display segments with low supply current requirements. The part is currently marked as Obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4054BNSR is determined by strict equivalence across the following critical parameters:

• Base Product Number: Both the main part and substitute must share the CD4054 base designation, ensuring identical functional architecture and pinout
• Display Type & Configuration: LCD driver with 4-segment configuration must be maintained
• Electrical Specifications: Voltage supply range (3V ~ 18V) and supply current (40 nA) must remain constant
• Operating Temperature Range: Full -55°C ~ 125°C range must be supported
• Mounting & Package Class: Surface mount technology with 16-SOIC package classification
• Compliance Standards: RoHS3 compliance and MSL Level 1 rating must be preserved

The CD4054BM qualifies as a manufacturer-recommended substitute based on these parameters. Packaging differences (tube vs. standard) and minor package width variations (3.90mm vs. 5.30mm within 16-SOIC class) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The CD4054BM is the manufacturer-recommended substitute for the CD4054BNSR. Both parts maintain identical electrical and functional specifications across all critical parameters. The primary distinction is product lifecycle status: the CD4054BNSR is marked Obsolete, while the CD4054BM carries Last Time Buy status, indicating extended availability for transition planning.

Selection of the CD4054BM is supported by:

• Identical base product architecture and pinout compatibility
• Matching electrical performance across the full operating range
• Equivalent compliance certifications (ROHS3, MSL Level 1)
• Maintained surface mount 16-SOIC package classification
• Availability from the original manufacturer (Texas Instruments)

Frequently Asked Questions (FAQ)

Q: Can the CD4054BM be used as a direct replacement for the CD4054BNSR?

A: Yes. Both parts share identical electrical specifications, pinout, and functional architecture. The CD4054BM is the manufacturer-recommended substitute and requires no circuit modifications.

Q: What is the difference between the CD4054BNSR and CD4054BM package specifications?

A: Both use 16-SOIC surface mount packaging. The CD4054BNSR specifies 5.30mm width, while the CD4054BM specifies 3.90mm width. Both dimensions fall within the 16-SOIC package class standard and are mechanically compatible with standard PCB footprints designed for this package type.

Q: Why is the CD4054BNSR marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The CD4054BM, marked as Last Time Buy, provides a transition path for designs currently using the CD4054BNSR.

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

A: No. Both parts maintain ROHS3 compliance, MSL Level 1 rating, and identical REACH and ECCN classifications.

Q: What is the inventory status for these parts?

A: The CD4054BNSR has 645 pieces in stock (new original). The CD4054BM has 2930 pieces in stock (new original, tube packaging).
