LM6144BIN Equivalent & Substitute Parts

Part Overview

The LM6144BIN is a general-purpose operational amplifier featuring four independent circuits in a 14-pin DIP package. This device provides rail-to-rail output capability with a slew rate of 25V/µs and a gain bandwidth product of 18 MHz, suitable for applications requiring moderate-speed signal conditioning and amplification across a wide supply voltage range of 1.8V to 24V.

The LM6144BIN 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.

• Input offset voltage (1.3 mV)
• Supply current per channel group (750µA total)
• Output current per channel (22 mA)
• Supply voltage range (1.8V to 24V)
• Operating temperature range (-40°C to 85°C)

Physical & Packaging Criteria:

• Package type (14-DIP)
• Pin count and pitch (0.300", 7.62mm)
• Mounting technology (Through Hole)

Compliance & Status Criteria:

• Manufacturer (Texas Instruments)
• Base product number alignment (LM614x series)

Parameter Comparison

Engineering Selection Recommendations

LM6144BIN/NOPB is the direct substitute for LM6144BIN. Selection of this part is based on the following factors:

Product Status: The LM6144BIN/NOPB carries an Active product status, ensuring ongoing manufacturer support, continued availability, and supply chain reliability. The original LM6144BIN is classified as Obsolete, making the /NOPB variant the recommended path for design continuity.

Electrical Equivalence: All electrical parameters are identical between the two parts. No circuit redesign or performance adjustment is required.

Compliance & Certifications: The LM6144BIN/NOPB is ROHS3 compliant, meeting current environmental and regulatory requirements. The original LM6144BIN is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance documentation, the /NOPB variant is the appropriate selection.

Packaging & Mechanical Compatibility: Both parts use identical 14-DIP through-hole packaging with matching pin pitch and footprint. Direct PCB substitution is supported without layout modifications.

Inventory & Availability: The LM6144BIN/NOPB maintains higher inventory levels (2468 pcs) compared to the original part (1405 pcs), supporting both immediate procurement and long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can LM6144BIN/NOPB be used as a direct replacement for LM6144BIN in existing designs?

A: Yes. The LM6144BIN/NOPB is electrically and mechanically identical to the LM6144BIN. All electrical parameters, pin configuration, and package dimensions match exactly. No circuit modifications are required for substitution.

Q: What is the difference between LM6144BIN and LM6144BIN/NOPB?

A: The primary differences are product status, packaging format, and compliance certification. The LM6144BIN/NOPB is Active (versus Obsolete), supplied in Tube packaging (versus standard packaging), and is ROHS3 compliant (versus non-compliant). Electrical performance and pin configuration are identical.

Q: Is the 14-DIP package footprint identical between both parts?

A: Yes. Both parts use the same 14-DIP package with 0.300" (7.62mm) pitch. PCB footprints and through-hole mounting requirements are identical. No layout changes are necessary.

Q: Does the /NOPB designation affect electrical performance?

A: No. The /NOPB suffix indicates lead-free (no lead) and RoHS compliance. It does not alter electrical specifications, performance characteristics, or functional behavior. All electrical parameters remain unchanged.

Q: Which part should be selected for new designs?

A: LM6144BIN/NOPB is the recommended selection for new designs. It carries Active product status, ensuring long-term availability and manufacturer support. It also meets current RoHS compliance requirements.

Q: Are there any temperature or supply voltage differences between the two parts?

A: No. Both parts operate across the identical temperature range (-40°C to 85°C) and support the same supply voltage span (1.8V to 24V). Operating conditions are fully equivalent.

Q: What is the significance of the Tube packaging format for LM6144BIN/NOPB?

A: Tube packaging is a standard distribution format for through-hole components, providing organized component presentation and automated handling compatibility. It does not affect electrical performance or pin configuration. Selection between packaging formats depends on procurement and assembly process requirements.
