TL3116CDR Equivalent & Substitute Parts

Part Overview

The TL3116CDR is a general-purpose comparator IC manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. This device features complementary, push-pull TTL output architecture and operates across a wide supply voltage range of 5V to 10V (single supply) or ±2.5V to ±5V (dual supply). The TL3116CDR is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence in output type, package compatibility, and electrical performance within specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TL3116CDR is determined by the following critical parameters: output type (complementary, push-pull, TTL), package form factor (8-SOIC surface mount), supply voltage range compatibility (5V to 10V single supply or ±2.5V to ±5V dual supply), and electrical performance specifications (input offset voltage, input bias current, output current, propagation delay, and CMRR).

The substitute parts are grouped into two categories:

Category 1: Direct Package Equivalents (8-SOIC Surface Mount) Parts maintaining the same 8-SOIC package form factor with compatible electrical specifications and active product status.

Category 2: Alternative Package Options (8-DIP and 8-TSSOP) Parts with equivalent electrical performance but different package configurations, suitable for applications where package form factor flexibility is acceptable.

Engineering Selection Recommendations

Primary Recommendation: TL3116IDR

The TL3116IDR is the manufacturer-recommended direct replacement for the obsolete TL3116CDR. Both devices share identical electrical specifications, package form factor (8-SOIC), and base product architecture. The TL3116IDR maintains active product status and ROHS3 compliance. The extended operating temperature range (-40°C to 85°C) of the TL3116IDR provides broader environmental coverage compared to the original TL3116CDR (0°C to 70°C). This part is suitable for applications requiring direct pin-for-pin and functional equivalence with minimal design modification.

Secondary Recommendation: MAX9013ESA+T

The MAX9013ESA+T offers an alternative with latch functionality in the same 8-SOIC package. This part features improved quiescent current performance (2.3mA maximum) and faster propagation delay (9ns maximum). However, the supply voltage range is narrower (4.5V to 5.5V), restricting use to single 5V supply applications. The MAX9013ESA+T is suitable for designs where reduced power consumption and faster response time are prioritized and supply voltage constraints are acceptable.

Alternative Recommendation: MAX913EUA+T

The MAX913EUA+T provides latch functionality in an 8-TSSOP/8-MSOP surface-mount package with extended operating temperature range (-40°C to 85°C). This part maintains the 5V to 10V supply voltage range and offers superior CMRR and PSRR performance (110dB CMRR, 100dB PSRR). The compact package footprint is advantageous for space-constrained applications. This part is suitable for designs requiring enhanced noise rejection and extended temperature operation.

Through-Hole Alternative: MAX913CPA+

The MAX913CPA+ is available in 8-DIP through-hole package format with latch functionality. This part is suitable for prototyping, legacy board designs, or applications where through-hole mounting is required. The 8-DIP package is not recommended for new surface-mount production designs.

All substitute parts maintain ROHS3 compliance and are currently in active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the TL3116IDR be used as a direct replacement for the TL3116CDR?

A: Yes. The TL3116IDR is the manufacturer-recommended replacement. Both parts share identical electrical specifications and the same 8-SOIC package. The TL3116IDR has an extended operating temperature range and active product status, making it the preferred choice for new designs and production.

Q: What is the difference between the TL3116 series and the MAX913 series?

A: The primary difference is the comparator type. The TL3116 series are general-purpose comparators, while the MAX913 series include integrated latch functionality. The MAX913 series also feature different supply voltage ranges and performance characteristics. Functional equivalence depends on whether latch functionality is required in the application.

Q: Can MAX9013ESA+T be used in applications requiring ±5V dual supply operation?

A: No. The MAX9013ESA+T operates only with single 5V supply (4.5V to 5.5V range). Applications requiring ±2.5V to ±5V dual supply operation must use TL3116IDR, MAX913CPA+, or MAX913EUA+T.

Q: What are the package form factor differences among the substitute parts?

A: TL3116IDR and MAX9013ESA+T use 8-SOIC surface-mount packages. MAX913EUA+T uses 8-TSSOP/8-MSOP surface-mount package (smaller footprint). MAX913CPA+ uses 8-DIP through-hole package. Package selection depends on PCB design requirements and manufacturing capabilities.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (TL3116IDR, MAX9013ESA+T, MAX913CPA+, MAX913EUA+T) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part offers the best power efficiency?

A: The MAX9013ESA+T has the lowest quiescent current (2.3mA maximum), making it the most power-efficient option. However, this part is limited to single 5V supply applications.

Q: Can substitute parts be mixed in the same production batch?

A: Mixing different part numbers in the same production batch is not recommended. Each substitute part has distinct electrical characteristics and package requirements. Consistent part selection ensures uniform performance and simplifies quality control and traceability.
