TLC27M4BIDR Equivalent & Substitute Parts

Part Overview

The TLC27M4BIDR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent amplifier circuits in a 14-SOIC surface mount package. This LinCMOS™ series device is classified as Active product status and is ROHS3 compliant. The TLC27M4BIDR is utilized in applications requiring low-power, general-purpose amplification with moderate bandwidth and slew rate characteristics. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameter ranges, or when supply chain availability necessitates alternative sourcing while maintaining circuit compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC27M4BIDR is determined by the following criteria:

Mechanical Compatibility: All substitute parts must feature identical or functionally equivalent 14-SOIC surface mount packaging with 0.154" (3.90mm) width to ensure PCB layout compatibility without redesign.

Electrical Parameter Ranges: Substitute parts must operate within the supply voltage range of 4V to 16V minimum and maximum specifications. The TLC27M4BIDR operates across -40°C to 85°C; substitute parts operating at -40°C to 125°C or 0°C to 70°C are acceptable depending on application temperature requirements.

Circuit Configuration: All substitute parts contain four independent amplifier circuits, maintaining functional equivalence in channel count and topology.

Key Differentiating Parameters: Slew rate (0.62 V/µs), gain bandwidth product (525 kHz), input bias current (0.7 pA), and output current per channel (30 mA) define the performance envelope. Substitute parts with lower slew rates or bandwidth may be used in applications not requiring the full performance specification. Substitute parts with higher performance specifications are functionally compatible.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and Active product status to ensure long-term availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

TS27L4AIDT (STMicroelectronics): This substitute operates across -40°C to 125°C, extending the upper temperature limit by 40°C relative to the TLC27M4BIDR. The TS27L4AIDT features significantly lower supply current (10 µA versus 570 µA), making it suitable for power-constrained applications. However, slew rate and gain bandwidth product are reduced (0.04 V/µs and 100 kHz respectively), limiting use to applications not requiring the full dynamic performance of the main part. Packaging and circuit count are identical. ROHS3 compliance and Active status are maintained.

TS27L4CDT (STMicroelectronics): This substitute is packaged in Cut Tape format and operates across 0°C to 70°C, representing a narrower temperature range than the main part. Supply current is identical to TS27L4AIDT at 10 µA. Input offset voltage is specified at 1.1 mV (higher than both the main part and TS27L4AIDT). This part is suitable for commercial-grade applications within the 0°C to 70°C range where extended low-temperature operation is not required. ROHS3 compliance and Active status are maintained. Inventory availability is highest among all substitutes at 30,200 pieces.

TS27L4IDT (STMicroelectronics): This substitute operates across -40°C to 125°C, matching the extended temperature range of TS27L4AIDT. Supply current remains at 10 µA. Slew rate and gain bandwidth product specifications are identical to TS27L4CDT (0.04 V/µs and 100 kHz). Packaging is specified as Cut Tape & Digi-Reel®. This part is suitable for industrial-temperature applications requiring low power consumption. ROHS3 compliance and Active status are maintained.

TS27M4IDT (STMicroelectronics): This substitute provides the closest performance match to the TLC27M4BIDR, with slew rate of 0.6 V/µs (compared to 0.62 V/µs) and gain bandwidth product of 1 MHz (exceeding the main part's 525 kHz). Operating temperature range extends to -40°C to 125°C. Supply current is 150 µA, significantly lower than the main part's 570 µA but higher than the TS27L4 variants. Output current per channel is 45 mA, exceeding the main part's 30 mA specification. This part is suitable for applications requiring performance characteristics approaching or exceeding the TLC27M4BIDR while maintaining lower power consumption than the original. ROHS3 compliance and Active status are maintained.

Frequently Asked Questions (FAQ)

Q: Can TS27L4AIDT, TS27L4CDT, and TS27L4IDT be used as direct replacements for TLC27M4BIDR in all applications?

A: These three parts share identical mechanical packaging (14-SOIC) and circuit count (4 circuits), enabling PCB-level compatibility without layout modification. However, electrical performance differs significantly. Slew rate is reduced from 0.62 V/µs to 0.04 V/µs, and gain bandwidth product decreases from 525 kHz to 100 kHz. These parts are suitable only for applications where the lower dynamic performance is acceptable. Applications requiring the full slew rate or bandwidth specifications of the TLC27M4BIDR cannot use these substitutes.

Q: What is the primary advantage of TS27L4 variants over TLC27M4BIDR?

A: The TS27L4 family (TS27L4AIDT, TS27L4CDT, TS27L4IDT) consumes significantly less supply current: 10 µA per four channels compared to 570 µA for the TLC27M4BIDR. This 57-fold reduction in supply current makes these parts suitable for battery-powered or ultra-low-power applications where the reduced bandwidth and slew rate are acceptable trade-offs.

Q: How does TS27M4IDT differ from the other STMicroelectronics substitutes?

A: TS27M4IDT provides higher performance than the TS27L4 variants, with slew rate of 0.6 V/µs (versus 0.04 V/µs) and gain bandwidth product of 1 MHz (versus 100 kHz). Supply current is 150 µA, intermediate between the TS27L4 variants (10 µA) and the TLC27M4BIDR (570 µA). TS27M4IDT is suitable for applications requiring performance approaching the main part while achieving moderate power reduction.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (TS27L4AIDT, TS27L4CDT, TS27L4IDT, TS27M4IDT) maintain ROHS3 compliance status, ensuring regulatory alignment with the TLC27M4BIDR.

Q: What is the temperature range consideration when selecting a substitute?

A: The TLC27M4BIDR operates across -40°C to 85°C. TS27L4AIDT, TS27L4IDT, and TS27M4IDT extend the upper limit to 125°C, suitable for high-temperature industrial applications. TS27L4CDT operates across 0°C to 70°C, representing a narrower commercial-grade range. Application temperature requirements must be verified against the selected substitute's operating range.

Q: Can TS27L4CDT be used in applications requiring -40°C operation?

A: No. TS27L4CDT specifies a minimum operating temperature of 0°C, making it unsuitable for applications requiring -40°C operation. For extended low-temperature operation, TS27L4AIDT, TS27L4IDT, or TS27M4IDT must be selected.

Q: What packaging formats are available for the substitute parts?

A: TS27L4AIDT is supplied in Tape & Reel (TR) format. TS27L4CDT is supplied in Cut Tape (CT) format. TS27L4IDT is supplied in Cut Tape (CT) & Digi-Reel® format. TS27M4IDT is supplied in Cut Tape (CT) format. All parts use identical 14-SOIC mechanical packaging. Packaging format selection depends on assembly process requirements and volume considerations.

Q: Is the TLC27M4BIDR still in active production?

A: Yes. The TLC27M4BIDR maintains Active product status with 2,983 pieces in current inventory, indicating ongoing availability and production support from Texas Instruments.
