Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV4112IP is determined by the following critical parameters:

Package Compatibility: The 8-DIP through-hole package is the primary mechanical constraint. Substitute parts must maintain identical pinout and footprint to ensure direct board-level replacement without layout modification.

Electrical Operating Range: Supply voltage span (2.5 V to 6 V minimum) and operating temperature range (-40°C to 125°C) define the functional envelope. Substitute parts must support the full specified range or a superset thereof.

Amplifier Configuration: Dual-circuit, rail-to-rail output topology is mandatory. The number of circuits and output type cannot be reduced or altered.

Performance Characteristics: Slew rate, gain bandwidth product, and output current capability establish performance boundaries. Substitute parts must meet or exceed these specifications to maintain circuit behavior.

Compliance Requirements: RoHS3 compliance is mandatory for environmental and regulatory conformance.

Substitute parts are grouped into two categories based on these criteria:

Category A - Direct Package Substitutes (8-DIP Through Hole): Parts maintaining identical package, mounting type, and electrical operating range with compatible or superior performance metrics.

Category B - Functional Equivalents (Alternative Package): Parts providing equivalent electrical functionality but requiring board redesign due to different package form factor.

Engineering Selection Recommendations

Direct Package Substitutes (8-DIP Through Hole - No Board Redesign Required):

MCP602-E/P is the primary substitute for applications operating within the 2.7 V to 6 V supply range. This Microchip CMOS amplifier maintains identical 8-DIP through-hole packaging and operating temperature range (-40°C to 125°C). The MCP602-E/P provides superior slew rate (2.3 V/µs versus 1.57 V/µs) and comparable gain bandwidth product (2.8 MHz versus 2.7 MHz). Supply current is reduced to 230 µA, improving power efficiency. Output current per channel is limited to 22 mA, which is a significant reduction from the TLV4112IP's 320 mA capability. This part is suitable for low-power signal conditioning applications where output current demand does not exceed 22 mA per channel. Product status is Active with unlimited moisture sensitivity rating.

MCP602-I/P is functionally equivalent to MCP602-E/P with identical electrical specifications. The operating temperature range is restricted to -40°C to 85°C, making this variant unsuitable for applications requiring the full -40°C to 125°C range. Selection of MCP602-I/P is appropriate only when the reduced temperature specification aligns with application requirements.

MCP6272-E/P is a general purpose amplifier substitute maintaining 8-DIP through-hole packaging and full operating temperature range (-40°C to 125°C). This part supports the lowest minimum supply voltage (2 V) among all substitutes, enabling operation in ultra-low-voltage applications. Slew rate is reduced to 0.9 V/µs, and output current per channel is limited to 25 mA. Supply current is minimized at 170 µA. This substitute is appropriate for low-speed, low-power applications where bandwidth and output current requirements are modest.

Alternative Package Substitute (Surface Mount - Board Redesign Required):

ALM2402FQPWPRQ1 is a power amplifier variant requiring surface-mount board redesign due to 14-PowerTSSOP packaging. This part provides the highest output current capability (750 mA per channel) and superior slew rate (3.4 V/µs). The minimum supply voltage is elevated to 4.5 V, restricting use in applications below this threshold. This substitute is appropriate for high-current output applications where board redesign is feasible. The part carries AEC-Q100 automotive qualification and is suitable for automotive-grade applications. Product status is Active.

Frequently Asked Questions (FAQ)

Q1: Can MCP602-E/P directly replace TLV4112IP without circuit modification?

A: MCP602-E/P maintains identical 8-DIP through-hole package and pinout, enabling direct board-level substitution. However, the reduced output current capability (22 mA per channel versus 320 mA) must be verified against circuit load requirements. If output current demand exceeds 22 mA per channel, this substitute is not suitable.

Q2: What is the primary limitation of MCP602-I/P compared to MCP602-E/P?

A: MCP602-I/P has a restricted operating temperature range of -40°C to 85°C, versus -40°C to 125°C for MCP602-E/P. Applications requiring operation above 85°C must use MCP602-E/P or alternative substitutes.

Q3: Why does MCP6272-E/P have lower slew rate than TLV4112IP?

A: MCP6272-E/P is optimized for ultra-low-voltage operation (minimum 2 V supply) and low-power consumption (170 µA supply current). The reduced slew rate (0.9 V/µs) reflects this design optimization. This substitute is appropriate for low-frequency signal processing where bandwidth is not critical.

Q4: Is ALM2402FQPWPRQ1 a pin-compatible replacement?

A: No. ALM2402FQPWPRQ1 uses 14-PowerTSSOP surface-mount packaging, which is not pin-compatible with the 8-DIP through-hole package of TLV4112IP. Board redesign is required for this substitution.

Q5: Which substitute provides the best overall performance match to TLV4112IP?

A: MCP602-E/P provides the closest performance match within the same package form factor, with superior slew rate and comparable bandwidth. However, the significantly reduced output current (22 mA versus 320 mA) must be evaluated against application requirements. For applications requiring high output current, ALM2402FQPWPRQ1 is the only substitute that exceeds the original specification.

Q6: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes (MCP602-E/P, MCP602-I/P, MCP6272-E/P, and ALM2402FQPWPRQ1) are ROHS3 compliant, maintaining environmental and regulatory conformance equivalent to the original TLV4112IP.

Q7: What supply voltage range is common to all substitutes?

A: The overlapping supply voltage range across all substitutes is 4.5 V to 6 V. Applications operating below 4.5 V cannot use ALM2402FQPWPRQ1. Applications operating below 2.7 V cannot use MCP602-E/P or MCP602-I/P. Only MCP6272-E/P supports the full 2 V to 6 V range.

Q8: Which substitute has the lowest power consumption?

A: MCP6272-E/P has the lowest supply current at 170 µA (x2 channels), followed by MCP602-E/P and MCP602-I/P at 230 µA. TLV4112IP consumes 700 µA, and ALM2402FQPWPRQ1 consumes 4 mA, making it the highest power option.
