Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC1203PSA is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

• Resolution and sampling rate (16-bit, 40 kSPS)
• Single differential input configuration
• Sigma-Delta architecture with internal reference
• SPI digital interface protocol
• Dual 5V supply voltage requirements
• Industrial temperature range (-40°C to 105°C)
• 8-SOIC surface mount package with identical physical dimensions
• RoHS3 compliance and MSL rating

The AMC1203BPSA meets all these criteria as a direct parametric equivalent within the Texas Instruments AMC1203 product family.

Parameter Comparison

Engineering Selection Recommendations

Both the AMC1203PSA and AMC1203BPSA are Last Time Buy components from Texas Instruments. Selection between these parts should be based on current inventory availability and supply chain requirements rather than technical differentiation, as they are parametrically identical.

The AMC1203BPSA currently maintains higher inventory levels (1105 pcs vs. 930 pcs), making it the preferred choice for new procurement and long-term design continuity. Both parts carry identical RoHS3 compliance and REACH status, ensuring regulatory compliance across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the AMC1203BPSA be used as a direct replacement for the AMC1203PSA?

A: Yes. The AMC1203BPSA is a parametric equivalent with identical electrical specifications, pin configuration, package dimensions, and performance characteristics. No circuit modifications are required for substitution.

Q: Are there any differences in pin configuration between these parts?

A: No. Both parts use the 8-SOIC package with identical pinout and signal assignments. PCB layout and schematic connections remain unchanged.

Q: Do both parts require the same PCB footprint?

A: Yes. Both components use the 8-SOIC (0.209", 5.30mm Width) package with identical physical dimensions and mounting requirements. Existing PCB designs require no modification.

Q: What is the significance of the Last Time Buy status?

A: Last Time Buy designation indicates these components are at end-of-life. Existing inventory represents the final production run. For applications requiring long-term supply assurance, evaluation of alternative architectures or newer product families may be necessary beyond current stock availability.

Q: Are compliance certifications identical between both parts?

A: Yes. Both the AMC1203PSA and AMC1203BPSA carry identical RoHS3 compliance, REACH Unaffected status, and MSL 3 moisture sensitivity ratings, ensuring equivalent regulatory and environmental compliance.
