Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC5688IRGC25 is determined by strict equivalence across all electrical and mechanical parameters. The substitute parts maintain identical specifications for resolution (16-bit), converter count (2), settling time (10.4 ns typical), output architecture (current sink, unbuffered, differential), supply voltage ranges (analog: 3V–3.6V; digital: 1.7V–1.9V), linearity performance (INL/DNL: ±4/±2 LSB), and package form factor (64-VQFN 9x9 with exposed pad).

The substitute parts differ only in product status (active versus obsolete) and packaging format (tape & reel, cut tape, or bulk). These variations do not affect electrical performance or circuit-level compatibility. The DAC5688 and DAC5689 base product numbers are functionally equivalent within this substitution set.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical equivalence to the DAC5688IRGC25. Selection among active alternatives should be based on packaging format availability and procurement requirements:

DAC5688IRGCR and DAC5689IRGCR are supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations. DAC5688IRGCT and DAC5689IRGCT are supplied in Cut Tape (CT) & Digi-Reel format, appropriate for moderate-volume or mixed-component procurement scenarios.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. The transition from obsolete to active product status provides improved long-term availability and supply chain stability without requiring circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can DAC5688IRGCR, DAC5688IRGCT, DAC5689IRGCR, and DAC5689IRGCT be used interchangeably with DAC5688IRGC25 in existing designs?

A: Yes. All substitute parts maintain identical electrical specifications, pin configurations, and package dimensions. Direct substitution requires no circuit modifications or PCB redesign.

Q: What is the difference between DAC5688 and DAC5689 base product numbers?

A: Within this substitution set, both base product numbers are functionally equivalent. They share identical electrical performance, resolution, converter count, and package specifications. Selection between them is determined by packaging format and inventory availability.

Q: How do packaging formats (Tape & Reel, Cut Tape, bulk) affect component selection?

A: Packaging format affects procurement logistics and assembly process compatibility but does not alter electrical performance or circuit functionality. Tape & Reel format is optimized for automated pick-and-place assembly. Cut Tape format accommodates manual or semi-automated assembly workflows. Bulk packaging is used for specific procurement scenarios. The component itself remains identical across all packaging options.

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

A: No. All parts maintain identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity levels (MSL 3, 168 hours). Regulatory and environmental requirements are uniform across the substitution set.

Q: Why is the DAC5688IRGC25 classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production. Active alternatives with identical specifications are available to support ongoing design requirements and new procurement needs.
