Substitute Part Grouping Explanation

Substitution eligibility for the LM7171BIN is determined by strict equivalence across the following critical parameters:

Electrical Performance Parameters:

• Amplifier Type: Voltage Feedback
• Number of Circuits: 1
• Slew Rate: 4100 V/µs
• Gain Bandwidth Product: 200 MHz
• -3dB Bandwidth: 220 MHz
• Current - Input Bias: 2.7 µA
• Voltage - Input Offset: 200 µV
• Current - Supply: 6.5 mA
• Current - Output / Channel: 118 mA
• Voltage - Supply Span: 5.5 V to 36 V
• Operating Temperature Range: -40°C to 85°C

Physical & Mechanical Parameters:

• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Supplier Device Package: 8-PDIP

Compliance & Status Parameters:

• Base Product Number: LM7171

Substitute parts must match all electrical performance parameters and physical package specifications. Packaging format (tube vs. other configurations) and RoHS compliance status do not affect functional substitutability but may impact procurement and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

LM7171BIN/NOPB is a direct functional equivalent to the LM7171BIN. Both parts share identical electrical performance specifications, package configuration, and thermal operating range. The primary distinctions are product lifecycle status and regulatory compliance:

The LM7171BIN is classified as obsolete, indicating end-of-life status with no further manufacturing planned. The LM7171BIN/NOPB carries a Last Time Buy designation, indicating a final production window before discontinuation.

The LM7171BIN/NOPB achieves ROHS3 compliance, whereas the LM7171BIN is RoHS non-compliant. For applications subject to RoHS regulatory requirements or procurement policies mandating RoHS compliance, the LM7171BIN/NOPB is the appropriate selection.

Both parts are supplied in 8-PDIP through-hole packages with identical pinout and mechanical dimensions, ensuring direct board-level compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can LM7171BIN/NOPB be used as a direct replacement for LM7171BIN in existing designs?

A: Yes. The LM7171BIN/NOPB is electrically and mechanically identical to the LM7171BIN. All electrical parameters, package dimensions, and pinout are equivalent. No circuit modification or board redesign is required for substitution.

Q: What is the difference between LM7171BIN and LM7171BIN/NOPB?

A: The primary differences are packaging format (tube vs. standard) and RoHS compliance status. The LM7171BIN/NOPB is ROHS3 compliant, while the LM7171BIN is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Why is the LM7171BIN marked as obsolete?

A: The LM7171BIN has reached end-of-life status. Texas Instruments has discontinued active production. The LM7171BIN/NOPB remains available under Last Time Buy terms, providing a final procurement window before complete discontinuation of the LM7171 series.

Q: Are there any thermal or operating condition differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C and share all thermal and electrical performance characteristics.

Q: Does the tube packaging of LM7171BIN/NOPB affect electrical performance?

A: No. Packaging format does not affect electrical performance or functional characteristics. Tube packaging is a distribution and handling format only.

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

A: The /NOPB suffix indicates lead-free (Pb-free) packaging and RoHS compliance. This designation reflects the component's compliance with environmental and regulatory standards.
