Substitute Part Grouping Explanation

Substitute parts for the LM2900NG4 are grouped based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Number of circuits: 4 independent amplifier channels
• Package type: 14-DIP (0.300", 7.62mm) through-hole mounting
• Pin configuration: 14-PDIP supplier device package
• RoHS compliance: ROHS3 Compliant

Secondary Electrical Criteria:

• Supply voltage range compatibility
• Operating temperature range coverage
• Slew rate and gain bandwidth product performance
• Input bias current and output current capabilities

The LM2900N is a direct manufacturer-recommended substitute from Texas Instruments, maintaining identical electrical specifications and package format. The LT1058CN#PBF and OP482GPZ are alternative substitutes from Analog Devices Inc., offering J-FET amplifier technology with different electrical characteristics but compatible 14-DIP packaging and pin assignments.

Parameter Comparison

Engineering Selection Recommendations

LM2900N (Texas Instruments)

The LM2900N is the manufacturer-recommended substitute for the LM2900NG4. This part maintains identical electrical specifications, including slew rate (20 V/µs), gain bandwidth product (2.5 MHz), input bias current (30 nA), and supply current (6.2 mA). The operating temperature range (-40°C to 85°C) and supply voltage span (4.4 V to 32 V) are identical. The LM2900N is available in tube packaging with 2785 units in stock and carries Last Time Buy status. This part is suitable for direct replacement in applications where the original LM2900NG4 specifications are required.

LT1058CN#PBF (Analog Devices Inc.)

The LT1058CN#PBF is an active-status substitute offering J-FET amplifier technology with enhanced performance characteristics. This part provides higher gain bandwidth product (5 MHz versus 2.5 MHz) and significantly lower input bias current (7 pA versus 30 nA). However, the operating temperature range is limited to 0°C to 70°C, and the minimum supply voltage is 20 V, which may not be compatible with applications requiring the full 4.4 V to 32 V supply range of the original part. The LT1058CN#PBF is suitable for applications where lower input bias current and higher bandwidth are beneficial and temperature and supply voltage constraints are acceptable.

OP482GPZ (Analog Devices Inc.)

The OP482GPZ is an active-status substitute offering J-FET amplifier technology with the lowest supply current consumption (210 µA for four channels versus 6.2 mA). This part provides the lowest input bias current (3 pA) and maintains the full operating temperature range (-40°C to 85°C) of the original part. However, the slew rate is reduced (9 V/µs versus 20 V/µs), and the minimum supply voltage is 9 V, which may not support applications requiring operation below 9 V. The OP482GPZ is suitable for low-power applications where supply current minimization is critical and the reduced slew rate is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the LM2900N be used as a direct replacement for the LM2900NG4?

A: Yes. The LM2900N maintains identical electrical specifications for all critical parameters: slew rate, gain bandwidth product, input bias current, supply current, output current, and supply voltage range. Both parts operate across -40°C to 85°C and use the same 14-DIP package. The LM2900N is the manufacturer-recommended substitute.

Q: What are the key differences between the LM2900NG4 and the LT1058CN#PBF?

A: The LT1058CN#PBF uses J-FET amplifier technology, resulting in significantly lower input bias current (7 pA versus 30 nA) and higher gain bandwidth product (5 MHz versus 2.5 MHz). However, the operating temperature range is restricted to 0°C to 70°C, and the minimum supply voltage is 20 V. These differences may affect compatibility in applications requiring extended temperature ranges or lower supply voltages.

Q: Is the OP482GPZ suitable for battery-powered applications?

A: The OP482GPZ offers the lowest supply current consumption (210 µA for four channels) among the available substitutes, making it suitable for low-power applications. However, the minimum supply voltage is 9 V, which may limit use in applications requiring operation below this threshold. Verify that the 9 V minimum supply voltage meets application requirements before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The LM2900N, LT1058CN#PBF, and OP482GPZ are all ROHS3 compliant, matching the compliance status of the original LM2900NG4.

Q: Can the LT1058CN#PBF be used in applications requiring -40°C operation?

A: No. The LT1058CN#PBF operating temperature range is 0°C to 70°C. Applications requiring operation at -40°C must use the LM2900N or OP482GPZ, both of which support the full -40°C to 85°C range.

Q: What is the difference between the packaging of LM2900NG4 and LM2900N?

A: Both parts use identical 14-DIP (0.300", 7.62mm) through-hole packages. The primary difference is packaging format: LM2900NG4 uses standard packaging, while LM2900N is supplied in tube packaging. Pin configuration and PCB footprint are identical.

Q: Which substitute part should be selected for high-speed applications?

A: The LT1058CN#PBF offers the highest gain bandwidth product (5 MHz) and slew rate (13 V/µs) among the J-FET alternatives. However, if the full supply voltage range (4.4 V to 32 V) and extended temperature range (-40°C to 85°C) of the original part are required, the LM2900N maintains the original specifications and is the appropriate selection.
