TLC4502ACDR Equivalent & Substitute Parts

Part Overview

The TLC4502ACDR is a CMOS dual-channel amplifier manufactured by Texas Instruments, designed for rail-to-rail signal conditioning applications. This device operates across a 4V to 6V supply range and is housed in an 8-SOIC surface mount package. The part is currently in active production status with 8140 units available in inventory.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of the TLC4502ACDR category. Substitution becomes necessary due to supply constraints, design optimization requirements, or application-specific performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC4502ACDR are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Dual-channel amplifier configuration (2 circuits)
• 8-SOIC surface mount package (0.154", 3.90mm width)
• Rail-to-rail output capability
• Supply voltage compatibility within specified ranges

Electrical Performance Boundaries: Substitute parts must operate within the functional envelope defined by the TLC4502ACDR specifications. The primary differentiators among qualified substitutes are slew rate, gain bandwidth product, input bias current, and supply current consumption. These parameters determine suitability for specific signal conditioning applications.

Identified Substitute Parts:

• MAX4282ESA+ (Analog Devices Inc./Maxim Integrated)
• MAX4252ESA+ (Analog Devices Inc./Maxim Integrated)
• MAX4257ESA+ (Analog Devices Inc./Maxim Integrated)

All substitute parts share identical package geometry, mounting type, and dual-channel architecture with the TLC4502ACDR.

Parameter Comparison

Engineering Selection Recommendations

MAX4282ESA+ Selection Criteria: The MAX4282ESA+ operates within the TLC4502ACDR supply voltage range (2.5V to 5.5V encompasses the 4V to 6V requirement). This part features lower supply current consumption (0.32 mA vs. 2.5 mA) and extended operating temperature range (-40°C to 85°C). The slew rate of 0.7 V/µs and gain bandwidth product of 2 MHz are lower than the TLC4502ACDR, making this substitute suitable for applications where power efficiency is prioritized over high-speed signal conditioning. All compliance certifications (ROHS3, MSL 1) are equivalent.

MAX4252ESA+ Selection Criteria: The MAX4252ESA+ provides the lowest slew rate (0.3 V/µs) and gain bandwidth product (3 MHz) among the substitutes. Supply current consumption is 0.42 mA. This part is appropriate for low-frequency, low-power applications where the reduced bandwidth and slew rate do not impact system performance. Extended temperature range and full compliance status match the TLC4502ACDR.

MAX4257ESA+ Selection Criteria: The MAX4257ESA+ offers the highest gain bandwidth product (22 MHz) and slew rate (2.1 V/µs) among substitutes, approaching the TLC4502ACDR performance envelope. Supply current consumption is 0.42 mA. This part is suitable for applications requiring higher bandwidth signal conditioning while maintaining lower power consumption than the original part. Extended temperature range and full compliance certifications are maintained.

All substitute parts are active production items with confirmed inventory availability and equivalent RoHS3 and REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can MAX4282ESA+ directly replace TLC4502ACDR in all applications?

A: Direct replacement is possible only when the application operates within the MAX4282ESA+ electrical specifications. The lower slew rate (0.7 V/µs vs. 2.5 V/µs) and reduced gain bandwidth product (2 MHz vs. 4.7 MHz) must be compatible with the signal conditioning requirements. The extended temperature range (-40°C to 85°C) provides broader operational capability than the TLC4502ACDR (0°C to 70°C). Package geometry and pin configuration are identical.

Q: What is the primary difference between MAX4252ESA+ and MAX4257ESA+?

A: Both parts share identical supply current consumption (0.42 mA), input bias current (0.1 pA), and input offset voltage (70 µV). The key differentiator is the gain bandwidth product: MAX4252ESA+ provides 3 MHz, while MAX4257ESA+ provides 22 MHz. The slew rate also differs: MAX4252ESA+ at 0.3 V/µs versus MAX4257ESA+ at 2.1 V/µs. Selection depends on the required signal bandwidth and slew rate performance for the application.

Q: Are all substitute parts compatible with the 4V to 6V supply range of the TLC4502ACDR?

A: All substitute parts operate within a 2.4V to 5.5V or 2.5V to 5.5V supply range, which encompasses the TLC4502ACDR specification of 4V to 6V. However, the maximum supply voltage for substitutes is 5.5V, which is below the 6V maximum of the original part. Applications requiring operation at 5.5V to 6V supply voltage must use the TLC4502ACDR or verify substitute part performance at the upper supply limit.

Q: Do all parts use the same 8-SOIC package?

A: Yes. The TLC4502ACDR and all three substitute parts (MAX4282ESA+, MAX4252ESA+, MAX4257ESA+) use identical 8-SOIC surface mount packaging with 0.154" (3.90mm) width. Pin configuration and PCB footprint compatibility are maintained across all parts.

Q: What is the inventory status of substitute parts?

A: MAX4282ESA+ has 1291 units in stock. MAX4252ESA+ has 1900 units in stock. MAX4257ESA+ has 2000 units in stock. All parts are listed as active production items with confirmed availability.

Q: Are all parts RoHS3 compliant?

A: Yes. The TLC4502ACDR and all substitute parts (MAX4282ESA+, MAX4252ESA+, MAX4257ESA+) are ROHS3 compliant with MSL rating of 1 (Unlimited). REACH status is unaffected for all parts.
