Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC38RF89IAAV are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Resolution: 14-bit conversion capability
• Channel Count: Dual D/A converters (2 channels)
• Output Configuration: Voltage-buffered with differential output capability
• Data Interface: JESD204B protocol support
• Supply Voltage Ranges: Analog (1.71V ~ 1.89V) and Digital (0.95V ~ 1.05V)
• Linearity Specifications: INL/DNL of ±4 and ±3 LSB
• Settling Performance: 1 ns typical settling time
• Package Format: 144-FCBGA (10x10) surface-mount BGA
• Temperature Range: -40°C to 85°C operation
• Compliance Standards: RoHS3 compliant, REACH unaffected, MSL 3

All substitute parts maintain identical specifications across these parameters, ensuring direct functional and mechanical interchangeability within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

All three parts—DAC38RF89IAAV, DAC38RF82IAAV, and DAC38RF85IAAV—are functionally equivalent and directly interchangeable based on electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Inventory Availability: DAC38RF82IAAV offers the highest inventory level at 1452 pieces, followed by DAC38RF85IAAV at 1102 pieces, and DAC38RF89IAAV at 1250 pieces. For applications requiring immediate procurement or bulk quantities, inventory status may influence part selection.

Compliance and Certification: All three parts maintain identical compliance certifications including RoHS3 compliance, REACH unaffected status, and MSL 3 moisture sensitivity rating. No compliance-based differentiation exists between the parts.

Production Status: All parts are active in production, ensuring long-term availability and supply chain continuity.

Tariff Classification: DAC38RF82IAAV and DAC38RF85IAAV share identical HTSUS code (8542.39.0001), while DAC38RF89IAAV uses code 8542.39.0040. This distinction may affect import duties and logistics costs depending on sourcing geography.

Frequently Asked Questions (FAQ)

Q: Can DAC38RF82IAAV or DAC38RF85IAAV be used as direct replacements for DAC38RF89IAAV?

A: Yes. All three parts are parametrically equivalent across all electrical specifications, output characteristics, data interface protocols, supply voltage requirements, and package formats. Direct substitution is supported without circuit modification.

Q: Are there any differences in the 144-FCBGA package between these parts?

A: No. All three parts use identical 144-FCBGA (10x10) surface-mount BGA packaging with matching pin configurations, thermal characteristics, and mounting requirements.

Q: Do these parts require different PCB layout or design considerations?

A: No. The identical package format, pin count, and electrical specifications eliminate any layout or design differentiation requirements.

Q: What is the significance of the different HTSUS codes?

A: HTSUS codes are tariff classification codes used for import/export purposes. The difference between 8542.39.0040 and 8542.39.0001 may result in different duty rates depending on the country of origin and destination. This is a logistics and compliance consideration rather than a technical one.

Q: Are all three parts suitable for industrial temperature range applications?

A: Yes. All parts operate across the -40°C to 85°C temperature range, meeting industrial-grade specifications.

Q: What is the MSL rating and why does it matter?

A: All three parts carry MSL 3 (168 Hours) rating, indicating moisture sensitivity level 3 with a floor life of 168 hours after moisture exposure. This specification applies uniformly across all substitute parts and requires standard moisture control during storage and handling.

Q: Can these parts be used interchangeably in existing designs without re-qualification?

A: Yes. The parametric equivalence across all electrical, mechanical, and interface specifications supports direct substitution without design re-qualification or functional testing.
