LM6171BIN Equivalent & Substitute Parts

Part Overview

The LM6171BIN is a voltage feedback amplifier manufactured by Texas Instruments, designed for high-speed signal conditioning applications. This integrated circuit contains a single amplifier circuit in an 8-PDIP package and is classified as obsolete. The LM6171BIN operates across a wide supply voltage range (5.5V to 34V) with a slew rate of 3600V/µs and gain bandwidth product of 100 MHz, making it suitable for precision analog signal processing.

Due to its obsolete product status, locating original inventory has become increasingly difficult. Identifying equivalent and substitute parts ensures design continuity and maintains system performance specifications without requiring circuit redesign.

Substitute Part Grouping Explanation

Substitution of the LM6171BIN is determined by strict equivalence across electrical performance and mechanical compatibility parameters. The following criteria establish valid substitute relationships:

Electrical Performance Equivalence:

• Amplifier Type: Voltage Feedback
• Number of Circuits: 1
• Slew Rate: 3600 V/µs
• Gain Bandwidth Product: 100 MHz
• -3dB Bandwidth: 160 MHz
• Current - Input Bias: 1 µA
• Voltage - Input Offset: 1.5 mV
• Current - Supply: 2.5 mA
• Current - Output / Channel: 116 mA
• Supply Voltage Range: 5.5V to 34V
• Operating Temperature Range: -40°C to 85°C

Mechanical Compatibility:

• Package Type: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Pin Configuration: 8-PDIP

Substitute parts must match all electrical parameters and maintain identical package specifications to ensure direct replacement without circuit modification or PCB redesign.

Parameter Comparison

Engineering Selection Recommendations

LM6171BIN/NOPB is the direct equivalent substitute for LM6171BIN. Both parts are manufactured by Texas Instruments and share identical electrical specifications and package configurations. The primary differences are:

Product Status: LM6171BIN is classified as Obsolete, while LM6171BIN/NOPB is designated Last Time Buy. This indicates LM6171BIN/NOPB has limited remaining availability and represents the final procurement window for this product line.

Compliance Status: LM6171BIN/NOPB carries ROHS3 Compliant certification, whereas LM6171BIN is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, LM6171BIN/NOPB is the appropriate selection.

Packaging: LM6171BIN/NOPB is supplied in Tube packaging, compared to standard packaging for LM6171BIN. Tube packaging is suitable for automated assembly processes and provides protection during storage and transport.

Inventory Availability: Current inventory of LM6171BIN/NOPB is 1987 pieces. Given the Last Time Buy status, procurement should be prioritized if this part is required for future production.

For new designs or production requiring RoHS compliance, LM6171BIN/NOPB is the recommended selection. For legacy systems currently using LM6171BIN, direct substitution with LM6171BIN/NOPB is electrically and mechanically compatible without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can LM6171BIN/NOPB be used as a direct replacement for LM6171BIN?

A: Yes. LM6171BIN/NOPB is a direct equivalent substitute. All electrical parameters, including slew rate, gain bandwidth product, input bias current, and supply voltage range, are identical. The 8-DIP package and through-hole mounting type are unchanged. No circuit redesign or PCB modification is required.

Q: What is the difference between LM6171BIN and LM6171BIN/NOPB?

A: The primary differences are product status, RoHS compliance, and packaging format. LM6171BIN is Obsolete and RoHS non-compliant, supplied in standard packaging. LM6171BIN/NOPB is Last Time Buy status, ROHS3 Compliant, and supplied in Tube packaging. Electrical specifications and package dimensions are identical.

Q: Why is LM6171BIN/NOPB designated Last Time Buy?

A: Last Time Buy status indicates this is the final production run before the product is discontinued. Inventory is limited and will not be replenished. Customers requiring this part should place orders before availability expires.

Q: Is RoHS compliance important for my application?

A: RoHS compliance is mandatory for products sold in the European Union and is increasingly required by customers worldwide. If your application or customer specifications require RoHS compliance, LM6171BIN/NOPB must be selected. LM6171BIN, being RoHS non-compliant, does not meet these requirements.

Q: Can I use LM6171BIN/NOPB in existing PCBs designed for LM6171BIN?

A: Yes. The 8-DIP package dimensions (0.300", 7.62mm) and pin configuration are identical. LM6171BIN/NOPB can be inserted into existing through-hole sockets or PCB footprints without modification. Electrical performance is equivalent across all specified parameters.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) packaging, confirming RoHS3 compliance. This designation specifies that the component meets lead-free soldering requirements and environmental regulations.

Q: How long will LM6171BIN/NOPB remain available?

A: As a Last Time Buy product, availability is limited and will be discontinued after current inventory is exhausted. No specific end-of-life date is provided. Procurement should be prioritized if this part is required for future production.

Q: Are there alternative amplifier options if LM6171BIN/NOPB becomes unavailable?

A: This reference page addresses only direct electrical and mechanical equivalents. Alternative amplifier solutions would require evaluation against specific application requirements and are outside the scope of this substitution guide.
