THS1031IPW Equivalent & Substitute Parts

Part Overview

The THS1031IPW is a 10-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for single-channel data acquisition applications. It features differential and single-ended input capability with a 30 MHz sampling rate and operates across a 3V to 5.5V supply voltage range. The device is packaged in a 28-TSSOP surface-mount package.

The THS1031IPW has reached obsolete product status. Identifying equivalent and substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this converter.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the THS1031IPW is determined by the following core parameters:

• Resolution: 10-bit conversion capability
• Architecture: Pipelined ADC topology
• Input Configuration: Single-channel with differential and single-ended input support
• Data Interface: Parallel output
• Supply Voltage Compatibility: Operating range overlap for both analog and digital supplies
• Temperature Range: Operating temperature specification of −40°C to +85°C
• Compliance: RoHS3 compliance and REACH unaffected status

The ADS825E qualifies as a manufacturer-recommended substitute based on matching resolution, architecture, input type, data interface, temperature range, and compliance certifications. Differences in sampling rate (40 MHz vs. 30 MHz), package type (28-SSOP vs. 28-TSSOP), and supply voltage specifications (5V fixed vs. 3V–5.5V range) are noted but do not preclude substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

The ADS825E is the manufacturer-recommended substitute for the obsolete THS1031IPW. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production continuity.

The ADS825E offers active product status, providing assured long-term availability and manufacturing support compared to the obsolete THS1031IPW. The substitute device maintains functional equivalence in resolution, architecture, input configuration, and data interface.

Design considerations include supply voltage specification differences: the ADS825E operates at fixed 5V supplies, whereas the THS1031IPW accepts a 3V to 5.5V range. Package geometry differs between the 28-TSSOP and 28-SSOP variants, requiring PCB layout evaluation. The ADS825E provides higher sampling rate capability (40 MHz vs. 30 MHz), which does not constrain substitution in applications designed for the original 30 MHz specification.

Frequently Asked Questions (FAQ)

Q: Can the ADS825E directly replace the THS1031IPW in existing designs?

A: Functional substitution is supported based on matching resolution, architecture, input type, and data interface. PCB layout modifications are required due to package geometry differences (28-TSSOP vs. 28-SSOP). Supply voltage must be verified; the ADS825E requires fixed 5V operation, whereas the THS1031IPW accepts 3V to 5.5V.

Q: What are the key differences between these devices?

A: The primary differences are sampling rate (40 MHz vs. 30 MHz), package type (28-SSOP vs. 28-TSSOP), supply voltage specification (5V fixed vs. 3V–5.5V range), and product status (active vs. obsolete). Functional parameters including resolution, architecture, and input configuration are identical.

Q: Are there package compatibility concerns?

A: Yes. The THS1031IPW uses a 28-TSSOP package (0.173" width, 4.40mm), while the ADS825E uses a 28-SSOP package (0.209" width, 5.30mm). PCB footprint and layout must be re-evaluated for the substitute device.

Q: Does the higher sampling rate of the ADS825E affect compatibility?

A: No. The ADS825E's 40 MHz sampling rate exceeds the THS1031IPW's 30 MHz specification. Applications designed for 30 MHz operation remain compatible; the higher capability does not introduce constraints.

Q: Are both devices RoHS and REACH compliant?

A: Yes. Both the THS1031IPW and ADS825E are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
