DAC5675IPHPR Equivalent & Substitute Parts

Part Overview

The DAC5675IPHPR is a 14-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring high-speed current output conversion. The device features a single D/A converter with LVDS parallel data interface and supports both external and internal reference configurations. The DAC5675IPHPR is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. The primary substitute maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the DAC5675IPHPR is determined by strict equivalence across all electrical and mechanical parameters. The substitute part DAC5675IPHP maintains identical specifications in the following critical areas:

Resolution: 14-bit conversion
Converter count: Single D/A converter
Output characteristics: Current-unbuffered with differential output
Data interface: LVDS parallel protocol
Reference configuration: External and internal support
Supply voltage ranges: 3.15V to 3.6V for both analog and digital supplies
Linearity performance: ±2 LSB INL and ±1.5 LSB DNL
Thermal performance: -40°C to 85°C operating range
Package form factor: 48-PowerTQFP (7x7mm)
Compliance certifications: ROHS3, REACH unaffected

The only distinction between the main part and substitute is packaging format (Tape & Reel versus Tray) and product lifecycle status (Obsolete versus Active).

Engineering Selection Recommendations

The DAC5675IPHP is the direct equivalent for the obsolete DAC5675IPHPR. Both parts share identical electrical performance, thermal characteristics, and mechanical specifications. The DAC5675IPHP offers the advantage of active product status, ensuring continued manufacturer support and availability. The packaging difference (Tray versus Tape & Reel) does not affect electrical compatibility or functional performance; selection between packaging formats depends on assembly process requirements and inventory management practices. Both parts maintain full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can DAC5675IPHP be used as a direct replacement for DAC5675IPHPR in existing designs?

A: Yes. The DAC5675IPHP is electrically and mechanically identical to the DAC5675IPHPR. All electrical parameters, pin configurations, package dimensions, and performance specifications are equivalent. No circuit modifications are required.

Q: What is the difference between Tape & Reel and Tray packaging?

A: Tape & Reel packaging is used for automated pick-and-place assembly processes, while Tray packaging is used for manual handling or alternative assembly methods. Both formats contain the same component with identical electrical characteristics. The choice depends on manufacturing process requirements.

Q: Why is the DAC5675IPHPR classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production lifecycle decisions. The DAC5675IPHP remains in active production, providing continuity for applications requiring this 14-bit DAC functionality.

Q: Are there any compliance differences between the two parts?

A: No. Both the DAC5675IPHPR and DAC5675IPHP maintain identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 3, 168 hours) is the same for both parts.

Q: What are the key electrical parameters that define this substitution?

A: The substitution is based on matching 14-bit resolution, single D/A converter architecture, 12 ns settling time, current-unbuffered differential output, LVDS parallel data interface, 3.15V to 3.6V supply voltage range, ±2/±1.5 LSB linearity, and -40°C to 85°C operating temperature range.

Q: Can the DAC5675IPHP be used in high-temperature applications?

A: The DAC5675IPHP operates within the -40°C to 85°C temperature range. Applications requiring operation outside this range require alternative component selection.
