Key Parameters

Substitute Part Grouping Explanation

Substitution of the THS5671AIPWR is determined by strict equivalence across the following critical parameters:

• Resolution: 14-bit conversion capability
• Converter Count: Single D/A converter configuration
• Output Architecture: Current-source, unbuffered topology
• Differential Output: Dual differential output capability
• Data Interface: Parallel input protocol
• Reference Configuration: Support for both external and internal reference sources
• Supply Voltages: Analog supply at 5V; digital supply range 3V ~ 5.5V
• Linearity Specifications: INL/DNL performance of ±2.5 LSB and ±2 LSB respectively
• Settling Time: 35ns typical response time
• Package Format: 28-TSSOP surface-mount package
• Environmental Compliance: ROHS3 compliance and REACH unaffected status

The THS5671AIPW represents the direct substitute, maintaining identical electrical specifications and package configuration while differing only in product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The THS5671AIPW is the designated substitute for the obsolete THS5671AIPWR. Both parts maintain identical electrical and mechanical specifications, ensuring direct functional compatibility in existing circuit designs. The primary distinction is product lifecycle status: the THS5671AIPWR is obsolete, while the THS5671AIPW remains in active production.

For new designs and ongoing system support, the THS5671AIPW is the appropriate selection. Both parts satisfy ROHS3 compliance requirements and maintain REACH unaffected status, supporting equivalent environmental and regulatory obligations. The packaging difference—reel versus tube format—reflects standard distribution practices and does not affect electrical performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can the THS5671AIPW directly replace the THS5671AIPWR in existing designs?

A: Yes. The THS5671AIPW provides complete electrical and mechanical equivalence to the THS5671AIPWR. All functional parameters, pin configurations, and performance specifications are identical. The substitute is suitable for direct board-level replacement without circuit modification.

Q: What is the difference between the reel and tube packaging formats?

A: Reel and tube packaging represent different distribution and handling formats for surface-mount components. Reel packaging is typically used for high-volume automated assembly, while tube packaging is common for lower-volume or manual assembly operations. Both formats contain identical components with no electrical or performance differences.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the THS5671AIPWR and THS5671AIPW maintain identical ROHS3 compliance and REACH unaffected status. Environmental and regulatory certifications are equivalent.

Q: Why is the THS5671AIPWR listed as obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions and market availability. The THS5671AIPW remains in active production and provides the current path for component procurement and system support.

Q: Are the pin configurations and package dimensions identical?

A: Yes. Both parts use the 28-TSSOP package format with identical pin assignments, pitch, and physical dimensions (0.173" width, 4.40mm). No PCB layout modifications are required for substitution.
