Substitute Part Grouping Explanation

Substitution of the LT1213CS8#TR is determined by compatibility across the following critical parameters: amplifier type (general purpose), number of circuits (2), package format (8-SOIC surface mount), supply voltage range compatibility, operating temperature range, and compliance certifications (RoHS3, REACH Unaffected).

The LT1213CS8#TR exhibits higher performance characteristics compared to many general purpose alternatives, specifically in slew rate (12V/µs) and gain bandwidth product (28 MHz). Substitute parts are grouped into two categories:

Direct Packaging Equivalent: LT1213CS8#TRPBF from Analog Devices Inc. is an identical electrical specification with Tape & Reel packaging, differing only in delivery format.

Functional Equivalents with Performance Trade-offs: Parts including LM258ADT, LM258DT, LM2904AYDT, LM2904DT, LM2904YDT, LM358ADT, and LM358DT share the dual-circuit general purpose amplifier architecture and 8-SOIC package format. These alternatives operate within overlapping supply voltage ranges (3V to 30V or 32V) and temperature ranges, but exhibit reduced slew rate (0.3V/µs to 0.6V/µs) and lower gain bandwidth product (700 kHz to 1.1 MHz).

Performance-Enhanced Alternative: LM7372MR/NOPB represents a voltage feedback amplifier with significantly higher performance specifications (3000V/µs slew rate, 120 MHz gain bandwidth product) but requires higher minimum supply voltage (9V) and operates at higher supply current (13mA per channel).

Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

LT1213CS8#TRPBF is the direct equivalent to LT1213CS8#TR, differing only in packaging format (Tape & Reel versus standard packaging). This part maintains all electrical specifications and is recommended when the original part number becomes unavailable. Both parts are Active status and RoHS3 compliant.

Functional Substitutes with Performance Reduction:

LM258ADT, LM258DT, LM2904AYDT, LM2904YDT, and LM358ADT are suitable substitutes when application requirements permit reduced slew rate and gain bandwidth product. These parts are Active status and RoHS3 compliant. LM258ADT and LM2904AYDT include AEC-Q100 automotive qualification. The LM258ADT and LM2904AYDT support extended operating temperature ranges (-40°C to 105°C and -40°C to 125°C respectively), providing advantages in temperature-critical applications.

LM2904DT and LM358DT are not recommended for new designs. LM2904DT carries "Not For New Designs" status, and LM358DT is Obsolete. Both remain RoHS3 compliant but should be avoided in new development.

Performance-Enhanced Alternative:

LM7372MR/NOPB is a voltage feedback amplifier offering significantly higher performance (3000V/µs slew rate, 120 MHz gain bandwidth product, 260 mA output current per channel). This part is Active status and RoHS3 compliant. Selection of this part requires verification that the application circuit can accommodate the higher minimum supply voltage requirement (9V minimum versus 2.5V for the LT1213CS8#TR) and increased supply current consumption (13mA per channel versus 3.4mA for the LT1213CS8#TR).

Compliance Considerations:

All listed substitute parts maintain RoHS3 compliance and REACH Unaffected status, matching the regulatory profile of the LT1213CS8#TR. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all general purpose alternatives, with LM7372MR/NOPB at MSL 3 (168 Hours), requiring controlled storage conditions.

Frequently Asked Questions (FAQ)

Q: Can LM258ADT be used as a direct replacement for LT1213CS8#TR?

A: LM258ADT shares the same 8-SOIC package and dual-circuit general purpose amplifier architecture. However, it exhibits reduced performance: slew rate of 0.6V/µs versus 12V/µs, and gain bandwidth product of 1.1 MHz versus 28 MHz. LM258ADT is suitable only if the application does not require the higher bandwidth and slew rate performance of the LT1213CS8#TR. Supply voltage range compatibility is reduced (3V to 30V versus 2.5V to 36V).

Q: What is the difference between LT1213CS8#TR and LT1213CS8#TRPBF?

A: These parts are electrically identical. The difference is in packaging format: LT1213CS8#TR uses standard packaging, while LT1213CS8#TRPBF is supplied in Tape & Reel format. Both are Active status, RoHS3 compliant, and maintain identical electrical specifications. Selection depends on assembly process requirements.

Q: Why does LM7372MR/NOPB require a higher minimum supply voltage?

A: LM7372MR/NOPB is a voltage feedback amplifier architecture designed for higher performance applications, requiring a 9V minimum supply voltage compared to 2.5V for the LT1213CS8#TR. This higher voltage requirement is inherent to the voltage feedback topology and supports the significantly higher slew rate (3000V/µs) and gain bandwidth product (120 MHz). Applications using lower supply voltages cannot accommodate this part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are RoHS3 compliant and REACH Unaffected, matching the regulatory compliance of the LT1213CS8#TR.

Q: Which substitute parts have automotive qualification?

A: LM258ADT and LM2904AYDT both carry AEC-Q100 automotive qualification. LM2904YDT also includes AEC-Q100 qualification. These parts are suitable for automotive applications requiring qualified components.

Q: Should LM2904DT or LM358DT be used in new designs?

A: No. LM2904DT is marked "Not For New Designs" and LM358DT is Obsolete. While both remain RoHS3 compliant and available in inventory, they should not be selected for new product development. Use LM2904AYDT or LM2904YDT as alternatives to the LM2904 family, or LM358ADT as an alternative to the LM358 family.

Q: What is the impact of using a substitute part with lower slew rate?

A: Slew rate determines the maximum rate of change of output voltage. The LT1213CS8#TR has a 12V/µs slew rate, while most general purpose substitutes (LM258, LM2904, LM358 families) have 0.3V/µs to 0.6V/µs. Applications requiring fast signal transitions or high-frequency amplification may not function correctly with lower slew rate parts. Verify application bandwidth requirements before substitution.

Q: Can the 8-PowerSOIC package of LM7372MR/NOPB be used in place of the 8-SOIC package?

A: The 8-PowerSOIC package is physically larger and has different pin configurations than the standard 8-SOIC package. PCB layout and footprint modifications are required. Direct board-level substitution is not possible without redesign.

Q: What is the operating temperature advantage of LM2904AYDT?

A: LM2904AYDT operates from -40°C to 125°C, compared to -40°C to 85°C for the LT1213CS8#TR. This extended upper temperature limit provides 40°C additional margin in high-temperature environments. LM2904DT also supports -40°C to 125°C operation.
