Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the THS1040IPWR is determined by strict alignment across the following critical parameters:

Resolution & Sampling Performance: Both the main part and substitute must maintain 10-bit resolution and 40 MHz sampling rate to preserve signal acquisition fidelity and system timing requirements.

Input Configuration: Single input with support for both differential and single-ended input types is mandatory for circuit compatibility.

Data Interface & Architecture: Parallel data interface with pipelined architecture ensures direct functional equivalence without requiring firmware or signal processing modifications.

Reference Architecture: Support for both external and internal reference types maintains design flexibility.

Package & Mounting: 28-TSSOP surface mount package ensures mechanical and thermal compatibility with existing PCB layouts.

Supply Voltage Ranges: Analog and digital supply voltage specifications must be compatible with the system power distribution design.

Environmental & Compliance: Operating temperature range, RoHS compliance, and regulatory certifications must meet or exceed the original specification requirements.

The ADC10040CIMTX/NOPB qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The ADC10040CIMTX/NOPB is a direct functional substitute for the obsolete THS1040IPWR. Both components are manufactured by Texas Instruments and maintain identical electrical specifications for resolution, sampling rate, input configuration, and package form factor.

The ADC10040CIMTX/NOPB offers an operational advantage: its supply voltage ranges (2.7V ~ 3.6V analog, 2.5V ~ 3.6V digital) are broader than the original part, providing greater flexibility in power supply design while remaining fully compatible with systems designed for the THS1040IPWR's 3V ~ 3.6V specification.

Both components carry ROHS3 compliance and identical operating temperature ratings (-40°C ~ 85°C), ensuring regulatory and environmental compatibility. The substitute part is currently in active production status, providing assured long-term availability compared to the obsolete original.

Frequently Asked Questions (FAQ)

Q: Can the ADC10040CIMTX/NOPB be used as a direct replacement for the THS1040IPWR without circuit modifications?

A: Yes. Both components share identical resolution (10-bit), sampling rate (40 MHz), input configuration (1 input, differential/single-ended), data interface (parallel), architecture (pipelined), and package (28-TSSOP). No circuit redesign is required.

Q: What is the difference in supply voltage specifications between these parts?

A: The ADC10040CIMTX/NOPB supports broader supply voltage ranges (2.7V ~ 3.6V analog, 2.5V ~ 3.6V digital) compared to the THS1040IPWR (3V ~ 3.6V for both). Systems designed for the original part's 3V ~ 3.6V specification operate within the substitute's range and are fully compatible.

Q: Are there packaging differences between these components?

A: No. Both components use the 28-TSSOP surface mount package with identical mechanical dimensions (0.173" width, 4.40mm). PCB layouts and assembly processes require no modification.

Q: What is the product status difference, and why does it matter?

A: The THS1040IPWR is obsolete, meaning Texas Instruments no longer manufactures it. The ADC10040CIMTX/NOPB is in active production, ensuring reliable supply chain access and long-term availability for new designs and production runs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and carry identical regulatory certifications (REACH Unaffected, ECCN EAR99). They meet the same environmental and compliance requirements.

Q: Is there a difference in moisture sensitivity between these parts?

A: Yes. The THS1040IPWR has MSL 1 (Unlimited), while the ADC10040CIMTX/NOPB has MSL 3 (168 Hours). This means the substitute part requires standard moisture control during storage and handling, which is standard industry practice for surface mount components.
