Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL59119IBZ is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must utilize the 8-SOIC surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Circuit Count: The substitute must provide three independent amplifier circuits to maintain functional equivalence in multi-channel reconstruction filter applications.

Supply Voltage Range: The substitute must operate within or encompass the 3V to 5.5V supply range of the original part to ensure compatibility with existing power distribution architectures.

Output Capability: The substitute must support the current output requirements of 65 mA per channel to maintain signal integrity and load-driving capability.

Compliance Standards: Both parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory and procurement requirements.

The NCS2563DG from onsemi meets these substitution criteria while offering enhanced bandwidth performance and improved moisture sensitivity characteristics.

Parameter Comparison

Engineering Selection Recommendations

The NCS2563DG qualifies as a functional substitute for the obsolete ISL59119IBZ based on the following engineering criteria:

Package Equivalence: Both devices utilize identical 8-SOIC surface mount packaging, eliminating the need for PCB redesign or layout modifications.

Circuit Configuration: Both parts provide three independent amplifier circuits, maintaining functional parity for multi-channel reconstruction filter applications.

Regulatory Compliance: The NCS2563DG maintains ROHS3 compliance and REACH unaffected status, satisfying procurement and environmental requirements equivalent to the original part.

Active Product Status: The NCS2563DG is an active product with ongoing manufacturer support, ensuring long-term availability and supply chain stability compared to the obsolete ISL59119IBZ.

Performance Considerations: The substitute exhibits higher bandwidth (33 MHz versus 8 MHz) and superior moisture sensitivity (MSL 1 versus MSL 3), representing performance enhancements. However, the substitute operates within a narrower supply voltage range (4.75V to 5.25V versus 3V to 5.5V) and provides reduced output current per channel (50 mA versus 65 mA). Design validation is required to confirm these parameter differences do not conflict with application-specific requirements.

Frequently Asked Questions (FAQ)

Q: Can the NCS2563DG be used as a direct replacement for the ISL59119IBZ without PCB modifications?

A: Yes. Both devices utilize the 8-SOIC package with identical physical dimensions (0.154" width, 3.90mm). Direct PCB footprint compatibility is confirmed. No layout changes are required for package accommodation.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Supply voltage range—the substitute operates within 4.75V to 5.25V versus the original 3V to 5.5V; (2) Bandwidth—the substitute provides 33 MHz versus 8 MHz; (3) Supply current—the substitute draws 22 mA versus 9.5 mA; (4) Output current per channel—the substitute provides 50 mA versus 65 mA; (5) Moisture sensitivity—the substitute offers MSL 1 (unlimited) versus MSL 3 (168 hours).

Q: Is the NCS2563DG suitable for applications requiring the full 3V to 5.5V supply range of the original part?

A: The NCS2563DG operates within 4.75V to 5.25V. Applications requiring operation below 4.75V or above 5.25V are not compatible with this substitute. Confirm your system operates within the 4.75V to 5.25V range before selection.

Q: Does the higher bandwidth of the NCS2563DG create any compatibility issues?

A: Higher bandwidth does not create compatibility issues for applications designed for 8 MHz operation. The substitute's 33 MHz bandwidth exceeds the original specification and provides performance margin. No adverse effects result from this enhancement in reconstruction filter applications.

Q: What is the impact of the reduced output current specification on the NCS2563DG?

A: The substitute provides 50 mA per channel versus 65 mA for the original part. Confirm that your load impedance and signal requirements do not exceed 50 mA per channel. If your application requires the full 65 mA output capability, the NCS2563DG may not be suitable.

Q: Are both parts RoHS compliant?

A: Yes. Both the ISL59119IBZ and NCS2563DG are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for procurement and environmental compliance.

Q: What does the improved moisture sensitivity (MSL 1) of the NCS2563DG mean for handling and storage?

A: MSL 1 indicates unlimited moisture sensitivity, meaning the device does not require special moisture control during storage or handling. The original part (MSL 3) requires controlled storage conditions with a 168-hour floor life limit after moisture exposure. The substitute offers simplified logistics and reduced handling constraints.
