TS1852IN Equivalent & Substitute Parts

Part Overview

The TS1852IN is a general purpose operational amplifier manufactured by STMicroelectronics, configured as a dual-circuit (2-channel) device in an 8-Mini DIP through-hole package. This component is classified as obsolete, indicating discontinued production and limited availability through standard distribution channels. The identification of equivalent and substitute parts is necessary to maintain design continuity and ensure project feasibility when original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS1852IN is evaluated based on the following critical parameters that define functional and physical compatibility:

Functional Compatibility Criteria:

• Amplifier Type: General Purpose classification
• Number of Circuits: Dual-channel (2-circuit) configuration
• Package / Case: 8-DIP form factor with 0.300" (7.62mm) pitch
• Mounting Type: Through-hole technology

Electrical Operating Range Criteria:

• Voltage Supply Span: Minimum 1.8 V to Maximum 6 V
• Operating Temperature: -40°C to 125°C
• Current Supply and Output specifications

The OP290GPZ from Analog Devices Inc. is identified as a substitute part. Both components share the same dual-circuit general purpose amplifier architecture and identical 8-DIP through-hole package configuration. However, electrical performance characteristics and operating ranges differ significantly and must be evaluated against specific application requirements.

Engineering Selection Recommendations

TS1852IN (Primary Component - Obsolete Status)

The TS1852IN is classified as obsolete and no longer in active production. Current inventory availability is limited to existing stock. This component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for the period of its availability.

OP290GPZ (Active Substitute)

The OP290GPZ is an active product from Analog Devices Inc., ensuring ongoing availability and long-term supply chain stability. This component is also ROHS3 compliant and REACH unaffected. The OP290GPZ maintains identical physical packaging (8-DIP through-hole) and dual-circuit general purpose amplifier architecture, enabling direct socket compatibility in most applications.

Key Differences Affecting Selection:

The OP290GPZ operates at a lower maximum supply voltage (36 V versus 6 V maximum for TS1852IN) and exhibits reduced performance in slew rate (0.012 V/µs versus 0.25 V/µs) and gain bandwidth product (20 kHz versus 630 kHz). The OP290GPZ demonstrates superior input offset voltage specification (0.125 mV versus 3 mV) and lower supply current consumption (25 µA versus 162 µA). The maximum operating temperature for OP290GPZ is 85°C, compared to 125°C for the TS1852IN.

Selection between these components depends on application-specific requirements for bandwidth, slew rate, temperature range, and supply voltage specifications. Physical package compatibility is confirmed for both components.

Frequently Asked Questions (FAQ)

Q: Can the OP290GPZ be used as a direct replacement for the TS1852IN in all applications?

A: Physical package compatibility is confirmed (both use 8-DIP through-hole configuration). However, electrical performance differs significantly. The OP290GPZ has lower slew rate (0.012 V/µs versus 0.25 V/µs) and reduced gain bandwidth product (20 kHz versus 630 kHz). Applications requiring higher bandwidth or faster signal transitions may not function correctly with the OP290GPZ. Verify that application bandwidth requirements do not exceed 20 kHz before substitution.

Q: What is the maximum operating temperature difference between these components?

A: The TS1852IN operates to 125°C maximum, while the OP290GPZ operates to 85°C maximum. Applications requiring operation above 85°C cannot use the OP290GPZ as a substitute.

Q: Are both components compliant with current regulatory standards?

A: Both the TS1852IN and OP290GPZ are ROHS3 compliant and REACH unaffected. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What is the supply voltage compatibility between these parts?

A: The TS1852IN operates with supply voltages from 1.8 V to 6 V. The OP290GPZ operates with supply voltages from 1.6 V to 36 V. The OP290GPZ supports higher maximum supply voltages but both components function within the 1.8 V to 6 V range of the original TS1852IN.

Q: How do the input offset voltage specifications compare?

A: The TS1852IN has an input offset voltage of 3 mV, while the OP290GPZ has an input offset voltage of 0.125 mV. The OP290GPZ provides superior input offset voltage performance, which may improve precision in applications sensitive to DC offset errors.

Q: What is the difference in supply current consumption?

A: The TS1852IN draws 162 µA of supply current, while the OP290GPZ draws 25 µA. The OP290GPZ offers significantly lower power consumption, which is advantageous for battery-powered or low-power applications.

Q: Are both components available in the same packaging format?

A: Both components use 8-DIP (0.300", 7.62mm) through-hole packaging. Pin-to-pin physical compatibility is confirmed, allowing direct socket substitution from a mechanical standpoint.
