TS931ID Equivalent & Substitute Parts

Part Overview

The TS931ID is a general-purpose operational amplifier manufactured by STMicroelectronics, housed in an 8-SOIC surface-mount package. This device features rail-to-rail output capability and is designed for low-power applications requiring single-channel amplification. The TS931ID is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS931ID is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is the base product number TS931, which defines the core amplifier architecture and performance characteristics. All substitute parts must maintain identical specifications for:

• Amplifier type and circuit count
• Output configuration (rail-to-rail)
• Slew rate and gain bandwidth product
• Input bias current and input offset voltage
• Supply current and output current capability
• Supply voltage range
• Operating temperature range
• Package type and physical dimensions
• Surface-mount compatibility
• Regulatory compliance (RoHS3, REACH)

The only permissible variation between the main part and substitutes is the packaging format (Tube versus Tape & Reel), which affects handling and delivery but does not alter electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The TS931IDT is the direct equivalent substitute for the TS931ID. Both parts are manufactured by STMicroelectronics and share identical electrical specifications and mechanical compatibility. The TS931IDT differs only in packaging format (Tape & Reel versus Tube) and product status (Active versus Obsolete).

Selection of TS931IDT is appropriate for new designs and ongoing production where active component availability is required. The TS931IDT maintains full compliance with RoHS3 and REACH regulations, identical to the original TS931ID. The Tape & Reel packaging format is standard for automated assembly processes and provides equivalent component reliability.

For applications currently using TS931ID in Tube packaging, transition to TS931IDT requires no circuit modifications, PCB layout changes, or electrical parameter adjustments. The 8-SOIC package dimensions and pin configuration remain identical, ensuring direct mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can TS931IDT be used as a direct replacement for TS931ID in existing designs?

A: Yes. The TS931IDT is electrically and mechanically identical to the TS931ID. All electrical parameters, package dimensions, and pin configurations match exactly. The only difference is the packaging format (Tape & Reel versus Tube), which does not affect circuit performance or component functionality.

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

A: Tube packaging delivers components in plastic tubes suitable for manual handling and small-quantity applications. Tape & Reel packaging delivers components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Both formats contain identical components with identical electrical specifications.

Q: Is the TS931IDT available in active production?

A: Yes. The TS931IDT is classified as Active product status with 17,800 pieces in stock. The original TS931ID is classified as Obsolete. For new procurement and ongoing production, TS931IDT is the recommended choice.

Q: Are there any compliance or regulatory differences between TS931ID and TS931IDT?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical regulatory certifications. Moisture Sensitivity Level is 1 (Unlimited) for both parts, indicating no special handling requirements.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is determined by matching: amplifier type (General Purpose), circuit count (1), output type (Rail-to-Rail), slew rate (0.05 V/µs), gain bandwidth product (100 kHz), input bias current (1 pA), input offset voltage (10 mV), supply current (20 µA), output current (5 mA), supply voltage range (2.7 V to 10 V), and operating temperature range (-40°C to 105°C).

Q: Can TS931IDT be used in applications requiring the -40°C to 105°C temperature range?

A: Yes. The TS931IDT is rated for -40°C to 105°C operating temperature, identical to the TS931ID. Both parts are suitable for industrial and extended-temperature applications within this range.

Q: Is the 8-SOIC package dimension identical between TS931ID and TS931IDT?

A: Yes. Both parts use the 8-SOIC package with 0.154" (3.90mm) width. PCB footprints, land patterns, and mechanical clearances are identical, requiring no design modifications for substitution.
