CD4054BM LCD Driver IC - Equivalent & Substitute Parts

Part Overview

The CD4054BM is a 4-segment LCD driver integrated circuit manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This component is classified as a Power Management (PMIC) device and functions as an LCD display driver for segment-based display applications. The CD4054BM is currently in Last Time Buy status, indicating that original inventory is limited and substitution planning is necessary for ongoing production requirements. The availability of equivalent parts ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4054BM is based on strict electrical and mechanical parameter matching. The primary substitute, CD4054BM96, maintains identical functional specifications across all critical parameters that determine interchangeability:

Key Parameters for Substitution Validity:

• Base product number (CD4054)
• Display type (LCD)
• Segment configuration (4 Segment)
• Supply voltage range (3V ~ 18V)
• Supply current specification (40 nA)
• Operating temperature range (-55°C ~ 125°C)
• Package designation (16-SOIC with 0.154" / 3.90mm width)
• Surface mount mounting type
• Compliance certifications (ROHS3, REACH Unaffected)

The CD4054BM96 differs only in packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy), with no impact on electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CD4054BM96 is a direct functional equivalent to the CD4054BM. Both parts are manufactured by Texas Instruments and share identical electrical characteristics, thermal specifications, and compliance certifications. The CD4054BM96 maintains Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the CD4054BM. Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications. The difference in packaging format (Tape & Reel versus Tube) does not affect component performance or PCB assembly compatibility for surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can CD4054BM96 be used as a direct replacement for CD4054BM in production? A: Yes. The CD4054BM96 is electrically and mechanically identical to the CD4054BM. Both parts share the same base product number, package type, and all critical electrical parameters. The only differences are packaging format and product lifecycle status.

Q: What is the significance of the packaging format difference (Tube vs. Tape & Reel)? A: Tube packaging is typically used for lower-volume orders and manual assembly, while Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly. Both formats contain the same component with identical specifications. Selection depends on assembly process requirements and order volume.

Q: Are there any compliance or certification differences between these parts? A: No. Both CD4054BM and CD4054BM96 are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory and environmental compliance is equivalent.

Q: Why is the CD4054BM marked as Last Time Buy? A: Last Time Buy status indicates that the manufacturer is discontinuing this specific packaging variant. The CD4054BM96 in Tape & Reel format remains in Active status, providing a viable path for continued supply of the CD4054 LCD driver functionality.

Q: Will the CD4054BM96 work with existing PCB designs for the CD4054BM? A: Yes. The 16-SOIC package dimensions, pin configuration, and electrical specifications are identical. No PCB redesign is required for substitution.
