TLC4501ID Equivalent & Substitute Parts

Part Overview

The TLC4501ID is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability and is designed for linear amplification applications requiring low input offset voltage and minimal input bias current. The TLC4501ID is classified as Last Time Buy, indicating discontinued production status. Identification of equivalent and substitute parts is necessary to ensure design continuity and procurement availability for ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC4501ID is determined by electrical and mechanical parameter compatibility within the general-purpose operational amplifier category. The critical parameters governing substitution are:

Mechanical Compatibility: All substitute parts must use the 8-SOIC surface mount package with 0.154" (3.90mm) width to ensure PCB layout compatibility without redesign.

Electrical Compatibility: Substitute parts must support rail-to-rail output operation and accommodate the supply voltage range of 4V to 6V minimum. The operating temperature range of -40°C to 125°C must be maintained.

Functional Compatibility: Single-circuit general-purpose amplifier topology is required. Slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current specifications define the performance envelope within which substitutes operate.

The TLC4501IDR (Tape & Reel packaging variant) is a direct manufacturer-recommended substitute with identical electrical specifications. The MAX4091ASA+ and MAX4091ASA+T (Analog Devices Inc./Maxim Integrated) are functional substitutes with different electrical performance characteristics but compatible mechanical and supply parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLC4501IDR

The TLC4501IDR is the manufacturer-recommended direct substitute for the TLC4501ID. Both devices are produced by Texas Instruments and share identical electrical specifications across all measured parameters. The only difference is packaging format: TLC4501ID is supplied in Tube packaging, while TLC4501IDR is supplied in Tape & Reel format. The TLC4501IDR maintains Active product status, ensuring continued availability and manufacturing support. Both parts are ROHS3 compliant with MSL 1 rating. Selection of TLC4501IDR is appropriate for designs requiring identical performance characteristics with improved supply chain continuity.

Secondary Substitute: MAX4091ASA+ / MAX4091ASA+T

The MAX4091ASA+ and MAX4091ASA+T (Analog Devices Inc./Maxim Integrated) are functional substitutes suitable for applications where the TLC4501ID electrical performance envelope can accommodate different specifications. These devices maintain rail-to-rail output operation, 8-SOIC packaging, and -40°C to 125°C operating temperature range. Both MAX4091 variants are Active products with ROHS3 compliance and MSL 1 rating.

Performance Trade-offs: The MAX4091 series exhibits lower slew rate (0.2V/µs versus 2.5V/µs) and reduced gain bandwidth product (500 kHz versus 4.7 MHz), resulting in slower signal response. Input bias current is higher (20 nA versus 1 pA) and input offset voltage is increased (30 µV versus 10 µV). Supply current consumption is significantly lower (130 µA versus 1 mA), and minimum supply voltage is reduced to 2.7V. These characteristics make MAX4091 suitable for low-power, low-frequency applications where the TLC4501ID performance is not required.

Packaging Consideration: MAX4091ASA+ is supplied in Tube packaging (matching TLC4501ID format), while MAX4091ASA+T is supplied in Tape & Reel format (matching TLC4501IDR format).

Frequently Asked Questions (FAQ)

Q: Can TLC4501IDR be used as a direct replacement for TLC4501ID?

A: Yes. The TLC4501IDR is the manufacturer-recommended substitute with identical electrical specifications. The difference is packaging format only: Tube versus Tape & Reel. PCB layout and circuit design require no modification. TLC4501IDR is the preferred choice for design continuity due to Active product status.

Q: What are the key differences between TLC4501ID and MAX4091ASA+?

A: Both devices use 8-SOIC packaging and support -40°C to 125°C operation. The TLC4501ID provides higher slew rate (2.5V/µs versus 0.2V/µs), higher gain bandwidth product (4.7 MHz versus 500 kHz), lower input bias current (1 pA versus 20 nA), lower input offset voltage (10 µV versus 30 µV), and higher supply current (1 mA versus 130 µA). The MAX4091ASA+ requires lower minimum supply voltage (2.7V versus 4V). Selection depends on application frequency response and power consumption requirements.

Q: Are all substitute parts compatible with existing PCB layouts?

A: Yes. All substitute parts use the 8-SOIC surface mount package with 0.154" (3.90mm) width. PCB footprints and land patterns are identical. No layout redesign is required for mechanical compatibility.

Q: What is the significance of Last Time Buy status for TLC4501ID?

A: Last Time Buy indicates the TLC4501ID is discontinued and no longer in production. Existing inventory is available for purchase, but future availability is not guaranteed. TLC4501IDR (Active status) or MAX4091 variants (Active status) should be selected for new designs or long-term production requirements.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. TLC4501ID, TLC4501IDR, MAX4091ASA+, and MAX4091ASA+T are all ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). All parts carry EAR99 export classification and HTSUS code 8542.33.0001.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-quantity assembly. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly equipment. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Can MAX4091ASA+T replace TLC4501ID in high-frequency applications?

A: No. The MAX4091ASA+T gain bandwidth product (500 kHz) is significantly lower than TLC4501ID (4.7 MHz). Applications requiring bandwidth above 500 kHz must use TLC4501IDR or TLC4501ID. The MAX4091ASA+T is suitable only for low-frequency signal conditioning and filtering applications.
