Key Parameters

Substitute Part Grouping Explanation

Substitution of the THS8133BCPHP is determined by the following critical parameters:

• Package Compatibility: Both parts use 48-HTQFP (7x7) surface mount packaging, ensuring mechanical and electrical pin compatibility.
• Resolution: Both maintain 10-bit resolution, preserving signal fidelity requirements.
• Data Interface: Both employ parallel data interface architecture.
• Voltage Supply Architecture: Both support analog and digital voltage supply sources.
• Compliance Standards: Both are ROHS3 compliant and REACH unaffected, meeting regulatory requirements.
• Moisture Sensitivity: Both carry MSL 3 rating (168 Hours), requiring identical handling and storage protocols.

The THS8136IPHP is qualified as a direct substitute based on these aligned parameters, despite differences in sampling rate and operating temperature range.

Engineering Selection Recommendations

The THS8136IPHP is the manufacturer-recommended substitute for the obsolete THS8133BCPHP. Selection of this substitute is supported by:

• Active Product Status: The THS8136IPHP is actively manufactured by Texas Instruments, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and safety standards.
• Package Equivalence: Identical 48-HTQFP (7x7) packaging enables direct PCB layout compatibility without redesign.
• Functional Compatibility: Matching 10-bit resolution, parallel data interface, and dual analog/digital supply architecture preserve core functionality.
• Enhanced Specifications: The THS8136IPHP provides higher sampling rate (180M vs. 80M) and extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C), offering performance headroom for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the THS8136IPHP be used as a direct replacement for the THS8133BCPHP without PCB modifications?

A: Yes. Both parts use identical 48-HTQFP (7x7) packaging with matching pin configurations, enabling direct substitution without PCB layout changes.

Q: What are the key differences between these parts?

A: The THS8136IPHP offers higher sampling rate (180M vs. 80M), extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C), and dual voltage supply ranges (1.65V ~ 1.95V and 3V ~ 3.6V vs. 3V ~ 5.25V). Resolution, data interface, and packaging remain identical.

Q: Is the THS8136IPHP compatible with the same supply voltage as the THS8133BCPHP?

A: Partial compatibility exists. The THS8136IPHP supports 3V ~ 3.6V operation, which overlaps with the THS8133BCPHP range of 3V ~ 5.25V. Applications requiring 5V operation must be evaluated against the THS8136IPHP's maximum 3.6V specification.

Q: Are moisture sensitivity and handling requirements the same?

A: Yes. Both parts carry MSL 3 rating (168 Hours), requiring identical storage, handling, and reflow protocols.

Q: Why is the THS8133BCPHP obsolete?

A: The THS8133BCPHP has been discontinued by Texas Instruments. The THS8136IPHP represents the current active product line for this functional category.
