LM2202N Equivalent & Substitute Parts

Part Overview

The LM2202N is a general-purpose video amplifier integrated circuit manufactured by Texas Instruments, housed in a 20-pin DIP package. This device is classified as obsolete, indicating it has been discontinued and is no longer in active production. The LM2202N was designed for general-purpose amplification applications requiring a -3dB bandwidth of 230 MHz with single supply voltage operation between 8V and 13.2V.

Due to its obsolete status, sourcing new units from primary distribution channels is limited. Identifying qualified substitute components ensures design continuity and maintains system performance specifications for applications currently utilizing the LM2202N.

Substitute Part Grouping Explanation

Substitution of the LM2202N is determined by the following critical parameters that must align between the main part and substitute candidates:

Mechanical Compatibility:

• Package type: 20-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Pin count and physical footprint must match for direct board-level replacement

Functional Compatibility:

• Device category: Linear Amplifiers
• Application class: General Purpose amplification
• Number of circuits and output configuration

Electrical Operating Range:

• Supply voltage range must encompass or be compatible with the original specification
• Output current capability per channel
• Supply current requirements

Regulatory & Environmental:

• RoHS compliance status
• REACH compliance status
• Moisture sensitivity classification

The TLS1233N from Texas Instruments meets the mechanical and functional substitution criteria through identical package configuration and general-purpose amplifier classification. However, electrical parameter differences exist that must be evaluated for specific application requirements.

Engineering Selection Recommendations

Product Status Consideration: The TLS1233N carries an Active product status, ensuring ongoing manufacturer support, availability through distribution channels, and continued compliance with current regulatory standards. The LM2202N's Obsolete status creates supply chain risk and limits access to new inventory.

Regulatory Compliance: The TLS1233N is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The LM2202N is RoHS non-compliant, which may present procurement challenges in regulated markets and applications subject to RoHS directives.

Electrical Parameter Differences: The TLS1233N operates within a narrower supply voltage range (11V ~ 13V) compared to the LM2202N (8V ~ 13.2V). Applications requiring operation below 11V supply voltage cannot use the TLS1233N as a direct substitute. The TLS1233N exhibits reduced -3dB bandwidth (100 MHz versus 230 MHz), which may impact high-frequency performance requirements. The TLS1233N draws higher supply current (84 mA versus 48 mA), affecting power budget calculations.

Circuit Configuration: The TLS1233N integrates three amplifier circuits compared to the LM2202N's single circuit. This architectural difference may provide functional advantages in multi-channel applications but requires circuit design evaluation for single-channel implementations.

Substitution Feasibility: Direct substitution is mechanically viable due to identical 20-DIP package configuration and through-hole mounting. Electrical substitution requires verification that the application's supply voltage range, bandwidth requirements, and power consumption constraints are compatible with the TLS1233N specifications.

Frequently Asked Questions (FAQ)

Q: Can the TLS1233N be used as a direct pin-for-pin replacement for the LM2202N?

A: The TLS1233N shares the identical 20-DIP package and through-hole mounting configuration, enabling physical board-level replacement without PCB modifications. However, electrical compatibility must be verified independently for each application, particularly regarding supply voltage range, bandwidth requirements, and power consumption.

Q: What is the primary reason the LM2202N requires substitution?

A: The LM2202N is classified as Obsolete, meaning Texas Instruments has discontinued production. This status creates supply chain constraints and limits availability through standard distribution channels. The TLS1233N, with Active product status, provides ongoing availability and manufacturer support.

Q: Are there supply voltage compatibility issues between the LM2202N and TLS1233N?

A: Yes. The LM2202N operates from 8V to 13.2V, while the TLS1233N operates from 11V to 13V. Applications requiring supply voltages below 11V cannot use the TLS1233N. The overlap range is 11V to 13V, where both devices are electrically compatible.

Q: How do the bandwidth specifications compare?

A: The LM2202N provides -3dB bandwidth of 230 MHz, while the TLS1233N provides 100 MHz. Applications requiring bandwidth above 100 MHz may experience performance degradation with the TLS1233N. Applications with bandwidth requirements below 100 MHz are compatible with the substitute.

Q: What is the significance of the circuit count difference?

A: The LM2202N contains one amplifier circuit, while the TLS1233N contains three. For single-channel applications, only one circuit of the TLS1233N would be utilized. The additional circuits may be left unused or configured for alternative functions depending on application requirements.

Q: Does the higher supply current of the TLS1233N affect system design?

A: The TLS1233N draws 84 mA compared to the LM2202N's 48 mA. Power supply capacity and thermal management must be evaluated to accommodate the increased current draw. This difference may impact battery life in portable applications or require power supply upgrades in fixed installations.

Q: What are the RoHS compliance implications?

A: The LM2202N is RoHS non-compliant, while the TLS1233N is ROHS3 compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the TLS1233N is the appropriate choice. Existing designs using the LM2202N may require compliance documentation review.

Q: Are there any moisture sensitivity differences?

A: The LM2202N has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The TLS1233N lists MSL as Not Applicable. Both devices are suitable for standard storage and handling conditions without special moisture control requirements.
