Substitute Part Grouping Explanation

Substitution eligibility for the AD5516ABCZ-2 is determined by strict equivalence across the following critical parameters:

Resolution and Channel Count: 12-bit resolution with 16 independent D/A converters
Output Characteristics: Voltage-unbuffered output with external reference requirement
Data Interface: SPI and DSP protocol support
Supply Voltage Ranges: Analog supply ±4.75V ~ 15.75V, 5V; Digital supply 2.7V ~ 5.25V
Linearity Specifications: INL/DNL ±2 (Max), ±0.5 LSB
Package Specification: 74-CSPBGA (12x12) surface mount configuration
Operating Temperature Range: -40°C ~ 85°C

Two substitute parts meet these criteria: AD5516ABCZ-1 and AD5516ABCZ-3. Both maintain identical electrical specifications and package requirements. The primary differentiator is settling time performance and product status.

Engineering Selection Recommendations

AD5516ABCZ-1 is the primary substitute for the obsolete AD5516ABCZ-2. This part maintains identical settling time (32µs) and all critical electrical parameters. AD5516ABCZ-1 carries Active product status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory alignment for new designs and production continuity.

AD5516ABCZ-3 is an alternative substitute with Active product status, ROHS3 compliance, and REACH unaffected certification. The settling time specification of 36µs represents a 4µs increase compared to the main part and AD5516ABCZ-1. This difference is acceptable for applications where settling time tolerance permits the extended specification. AD5516ABCZ-3 availability (1510 Pcs) exceeds AD5516ABCZ-1 (1331 Pcs), providing supply flexibility.

Both substitutes are electrically and mechanically compatible with the AD5516ABCZ-2 across all specified parameters. Selection between AD5516ABCZ-1 and AD5516ABCZ-3 depends on settling time requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can AD5516ABCZ-1 and AD5516ABCZ-3 be used interchangeably with AD5516ABCZ-2?

A: Both parts are direct substitutes for the obsolete AD5516ABCZ-2 across all specified electrical and mechanical parameters. The 74-CSPBGA (12x12) package, pin configuration, and functional specifications are identical. Selection between the two depends on settling time tolerance and supply availability.

Q: What is the difference between AD5516ABCZ-1 and AD5516ABCZ-3?

A: The primary difference is settling time: AD5516ABCZ-1 specifies 32µs, while AD5516ABCZ-3 specifies 36µs. All other electrical parameters, package specifications, and compliance certifications are identical. Both are Active products with ROHS3 compliance and REACH unaffected status.

Q: Are there package or pinout differences between these parts?

A: No. All three parts use the identical 74-CSPBGA (12x12) surface mount package with the same pinout and mechanical specifications. Direct PCB layout compatibility is maintained.

Q: What compliance certifications apply to the substitute parts?

A: Both AD5516ABCZ-1 and AD5516ABCZ-3 are ROHS3 compliant and REACH unaffected. The main part (AD5516ABCZ-2) compliance status was not specified in the available data.

Q: Which substitute should be selected for new designs?

A: AD5516ABCZ-1 is recommended for new designs requiring the 32µs settling time specification. If supply constraints exist or the 36µs settling time is acceptable for the application, AD5516ABCZ-3 provides an alternative with higher current inventory availability.

Q: Are the supply voltage ranges identical across all three parts?

A: Yes. All three parts operate with identical analog supply range (±4.75V ~ 15.75V, 5V) and digital supply range (2.7V ~ 5.25V). External reference voltage requirements are also identical.
