THS5671AIPWRG4 Equivalent & Substitute Parts

Part Overview

The THS5671AIPWRG4 is a 14-bit digital-to-analog converter (DAC) from Texas Instruments, part of the CommsDAC™ series. This component features a single D/A converter with current output (unbuffered), parallel data interface, and support for both external and internal reference types. The device operates across a wide temperature range of -40°C to 85°C and is housed in a 28-TSSOP surface mount package.

The THS5671AIPWRG4 is classified as obsolete. Locating equivalent or substitute parts is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. The substitute identified maintains full electrical and mechanical compatibility while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the THS5671AIPWRG4 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain:

• Identical resolution: 14-bit DAC
• Identical converter count: 1 D/A converter
• Identical output characteristics: Current output (unbuffered) with differential capability
• Identical interface: Parallel data interface
• Identical reference support: External and internal reference types
• Identical supply voltage specifications: 5V analog, 3V–5.5V digital
• Identical performance metrics: 35ns settling time, ±2.5/±2 LSB INL/DNL
• Identical package: 28-TSSOP surface mount
• Identical compliance: ROHS3, MSL Level 1

The THS5671AIPW meets all these criteria and serves as the direct substitute for the obsolete THS5671AIPWRG4.

Parameter Comparison

Engineering Selection Recommendations

The THS5671AIPW is the direct substitute for the obsolete THS5671AIPWRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, performance characteristics, and package geometry. The primary distinction is product status: the THS5671AIPWRG4 is obsolete, while the THS5671AIPW maintains active status with current manufacturing support.

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system updates. The THS5671AIPW is available in tube packaging and offers superior inventory availability (1248 pcs vs. 1111 pcs), making it the preferred selection for ongoing production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the THS5671AIPW directly replace the THS5671AIPWRG4 in existing designs?

A: Yes. The THS5671AIPW is electrically and mechanically identical to the THS5671AIPWRG4. All pin assignments, signal levels, timing characteristics, and package dimensions are equivalent. No circuit modifications are required.

Q: What is the difference between the THS5671AIPWRG4 and THS5671AIPW?

A: The primary difference is product status. The THS5671AIPWRG4 is classified as obsolete, while the THS5671AIPW is active. The packaging differs (the substitute is supplied in tubes), but electrical performance and pinout are identical.

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

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN classification (EAR99). Regulatory requirements are satisfied by either part.

Q: What is the 28-TSSOP package specification?

A: The 28-TSSOP is a surface mount thin shrink small outline package with 28 pins, measuring 0.173 inches (4.40mm) in width. This package is standard across both the main part and substitute.

Q: Can I use the THS5671AIPW in new designs?

A: Yes. The THS5671AIPW is an active product with full manufacturing support. It is suitable for new designs, production builds, and legacy system maintenance.
