LM6154BCMX Equivalent & Substitute Parts

Part Overview

The LM6154BCMX is a general-purpose operational amplifier featuring four independent circuits in a 14-SOIC surface-mount package. This device delivers rail-to-rail output capability with a 30V/µs slew rate and 80 MHz gain bandwidth product, suitable for precision analog signal conditioning and amplification applications across supply voltages from 2.7V to 24V.

The LM6154BCMX is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for existing applications and new designs requiring compatible performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM6154BCMX is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Four independent operational amplifier circuits
• Rail-to-rail output configuration
• Slew rate of 30V/µs minimum
• Gain bandwidth product of 80 MHz minimum
• Input bias current of 500 nA maximum
• Input offset voltage of 300 µV maximum
• Supply current of 1.6mA per four channels maximum
• Output current per channel of 16.9 mA minimum
• Supply voltage range: 2.7V to 24V

Mechanical & Packaging Criteria:

• 14-SOIC surface-mount package (0.154" width, 3.90mm)
• Moisture sensitivity level MSL 1 (unlimited)

Compliance Criteria:

• RoHS compliance status
• REACH compliance status

The LM6154BCMX/NOPB is identified as a direct substitute based on identical electrical specifications, package configuration, and compliance certifications. The primary distinction is product status: the base LM6154BCMX is obsolete, while the LM6154BCMX/NOPB maintains active status with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The LM6154BCMX/NOPB is the appropriate selection. This part maintains active product status, carries ROHS3 compliance certification, and demonstrates significantly higher inventory availability (5615 units versus 2000 units). The NOPB designation indicates lead-free manufacturing, aligning with current environmental and regulatory standards.

For Existing Applications Using LM6154BCMX: Direct substitution with LM6154BCMX/NOPB is supported. All electrical parameters, package configuration, and functional characteristics remain identical. The transition from RoHS non-compliant to ROHS3 compliant status presents no technical incompatibility and improves long-term supply chain sustainability.

Compliance Considerations: Applications subject to RoHS3 or equivalent environmental regulations must transition to LM6154BCMX/NOPB. Both parts maintain REACH Unaffected status, indicating no restrictions under REACH chemical regulations.

Frequently Asked Questions (FAQ)

Q: Can LM6154BCMX/NOPB replace LM6154BCMX in existing designs without circuit modification?

A: Yes. The LM6154BCMX/NOPB is electrically and mechanically identical to the LM6154BCMX. All performance parameters, pin configurations, and package dimensions are equivalent. No circuit redesign or PCB layout changes are required.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" designation indicates a lead-free (Pb-free) manufacturing process compliant with RoHS3 standards. This affects manufacturing and environmental compliance but does not alter electrical performance or functional characteristics.

Q: Why is the LM6154BCMX classified as obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for this part number. The LM6154BCMX/NOPB represents the current active equivalent, ensuring continued availability and manufacturer support.

Q: Are there inventory differences between these parts?

A: Yes. LM6154BCMX inventory is 2000 units, while LM6154BCMX/NOPB inventory is 5615 units. For applications requiring immediate or high-volume procurement, the NOPB variant offers superior availability.

Q: Is the 14-SOIC package compatible with existing PCB designs?

A: Yes. Both parts use identical 14-SOIC surface-mount packaging with 0.154" width and 3.90mm body dimensions. PCB footprints, solder reflow profiles, and assembly processes remain unchanged.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts require no special moisture control during storage, handling, or assembly. Standard warehouse conditions and conventional PCB assembly processes are sufficient.

Q: Can these parts be used in applications requiring RoHS compliance?

A: The LM6154BCMX/NOPB is ROHS3 compliant and suitable for RoHS-regulated applications. The original LM6154BCMX is RoHS non-compliant and should not be used in new designs subject to RoHS requirements.
