TS514ID Equivalent & Substitute Parts

Part Overview

The TS514ID is a general-purpose operational amplifier integrated circuit manufactured by STMicroelectronics, configured as a 4-circuit device in a 14-SOIC surface-mount package. This component is classified as obsolete, indicating that direct procurement from the original manufacturer is no longer available through standard distribution channels. The TS514ID operates across a wide supply voltage range of 6 V to 30 V and maintains functionality across the industrial temperature range of -40°C to 125°C. Identification of equivalent and substitute parts is necessary to maintain design continuity, ensure production availability, and support long-term system maintenance where the original component is no longer in active production.

Substitute Part Grouping Explanation

Substitution of the TS514ID is determined by strict alignment of electrical and mechanical parameters within the general-purpose operational amplifier category. The following criteria establish substitution validity:

Primary Substitution Criteria:

Number of circuits: 4 (mandatory match)
Package type: 14-SOIC surface-mount configuration (mandatory match)
Operating temperature range: Minimum -40°C, maximum 125°C or higher (must encompass or exceed TS514ID range)
Supply voltage span: Minimum 6 V or lower, maximum 30 V or higher (must encompass or exceed TS514ID range)
Amplifier type: General Purpose (functional category match)

Secondary Compatibility Parameters:

Slew rate: 1.5 V/µs or higher (TS514ID baseline)
Gain bandwidth product: 3 MHz or higher (TS514ID baseline)
Input bias current: 50 nA or lower (TS514ID baseline)
Input offset voltage: 500 µV or lower (TS514ID baseline)
Output current per channel: 23 mA or higher (TS514ID baseline)

Substitute parts are grouped into two categories: direct functional equivalents that meet or exceed all secondary parameters, and compatible alternatives that maintain primary substitution criteria while offering enhanced performance characteristics in specific parameters.

Engineering Selection Recommendations

Direct Functional Equivalent:

The OPA4171AID from Texas Instruments serves as the primary direct substitute for the TS514ID. This component maintains identical slew rate (1.5 V/µs) and gain bandwidth product (3 MHz) specifications, ensuring functional equivalence in signal processing applications. The OPA4171AID is in active production status, providing assured long-term availability. It meets the full operating temperature range requirement (-40°C to 125°C) and encompasses the TS514ID supply voltage range (2.7 V to 36 V). The OPA4171AID offers superior input bias current (8 pA versus 50 nA) and input offset voltage (250 µV versus 500 µV), representing performance enhancement in precision applications. Both components are ROHS3 compliant and carry identical ECCN and HTSUS classifications.

Enhanced Performance Alternatives:

The ADA4004-4ARZ series (available in three packaging configurations: ADA4004-4ARZ, ADA4004-4ARZ-R7, and ADA4004-4ARZ-RL) from Analog Devices Inc. provides superior performance characteristics with higher slew rate (2.7 V/µs) and gain bandwidth product (12 MHz). These components maintain the 14-SOIC package format and -40°C to 125°C operating temperature range. The ADA4004 series exhibits exceptional input offset voltage (40 µV) and input bias current (40 nA), suitable for precision instrumentation. Supply voltage range spans 10 V to 30 V, which encompasses the TS514ID minimum requirement of 6 V. All ADA4004 variants are ROHS3 compliant and in active production.

Cost-Optimized Alternatives:

The LM324AMX/NOPB from Texas Instruments represents a cost-effective substitute with extensive inventory availability (36,756 pieces). This component maintains the 14-SOIC package and operates across 0°C to 70°C temperature range, which does not fully encompass the TS514ID industrial temperature specification. The LM324AMX/NOPB operates across 3 V to 32 V supply range and provides 40 mA output current per channel. This option is suitable for applications where the reduced temperature range is acceptable and cost optimization is prioritized.

The LM2900D from Texas Instruments offers distinctive performance with 20 V/µs slew rate and operates across 4.4 V to 32 V supply range. Operating temperature extends to -40°C to 85°C, providing partial coverage of the TS514ID industrial range. This component is ROHS3 compliant with unlimited moisture sensitivity level.

Compliance and Regulatory Status:

All recommended substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the TS514ID. All components carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications, ensuring regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can the OPA4171AID directly replace the TS514ID without circuit modification?

A: The OPA4171AID maintains identical slew rate and gain bandwidth product specifications as the TS514ID, with superior input characteristics. The 14-SOIC package pinout is identical. Direct substitution is valid for applications operating within the TS514ID supply voltage range (6 V to 30 V) and temperature range (-40°C to 125°C). The OPA4171AID's enhanced performance parameters do not introduce incompatibility.

Q: What is the primary limitation of the LM324AMX/NOPB as a substitute?

A: The LM324AMX/NOPB operates across 0°C to 70°C temperature range, which does not encompass the TS514ID industrial specification of -40°C to 125°C. This component is suitable only for applications operating within the 0°C to 70°C window. All other electrical parameters and the 14-SOIC package format are compatible.

Q: Why do the ADA4004 variants show different packaging options?

A: The ADA4004-4ARZ, ADA4004-4ARZ-R7, and ADA4004-4ARZ-RL represent identical electrical specifications with different packaging and delivery formats. The base part (ADA4004-4ARZ) is supplied in tube packaging. The R7 variant uses Cut Tape and Digi-Reel format. The RL variant uses Tape & Reel format. Selection depends on manufacturing assembly requirements and inventory management preferences. All three variants are electrically and functionally equivalent.

Q: Does the LM2900D provide full temperature range coverage?

A: The LM2900D operates across -40°C to 85°C, which covers the lower portion of the TS514ID range but does not extend to the maximum 125°C specification. This component is suitable for applications with maximum operating temperature of 85°C. The LM2900D offers exceptional slew rate performance (20 V/µs) compared to the TS514ID (1.5 V/µs).

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed in this reference maintain ROHS3 compliance status, consistent with the TS514ID. All components are REACH unaffected and carry identical ECCN and HTSUS classifications.

Q: What is the significance of moisture sensitivity level differences?

A: The TS514ID, LM2900D, LM2900DR, LM324ADR2G, LM324AM, LM324AM/NOPB, and LM324AMX/NOPB carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The OPA4171AID, ADA4004-4ARZ, ADA4004-4ARZ-R7, and ADA4004-4ARZ-RL carry MSL 3 (168 Hours), requiring controlled humidity storage and limiting shelf life to 168 hours after moisture barrier bag opening. This affects supply chain management and inventory control procedures.

Q: Can the ADA4004 series be used in applications requiring the full -40°C to 125°C range?

A: Yes. The ADA4004-4ARZ, ADA4004-4ARZ-R7, and ADA4004-4ARZ-RL all operate across -40°C to 125°C, fully encompassing the TS514ID temperature specification. These components are suitable for industrial temperature range applications.

Q: What distinguishes the OPA4171AID from the ADA4004 series?

A: The OPA4171AID maintains identical slew rate (1.5 V/µs) and gain bandwidth product (3 MHz) as the TS514ID, providing functional equivalence. The ADA4004 series offers enhanced performance with 2.7 V/µs slew rate and 12 MHz gain bandwidth product. The OPA4171AID is the appropriate choice for direct functional replacement. The ADA4004 series is appropriate when enhanced bandwidth and slew rate performance are beneficial to the application.
