EL8108ISZ Equivalent & Substitute Parts

Part Overview

The EL8108ISZ is a dual-channel current feedback video amplifier manufactured by Renesas Electronics Corporation in an 8-SOIC surface mount package. This device is classified as obsolete, indicating it is no longer in active production. The EL8108ISZ operates across supply voltage ranges of 5V to 12V (single supply) or ±2.5V to ±6V (dual supply), with a -3dB bandwidth of 200 MHz and slew rate of 800V/µs. Due to its obsolete status, identification of equivalent substitute components is necessary for design continuity and procurement of new production units.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL8108ISZ is determined by the following critical parameters that must align between the main part and substitute components:

Package Compatibility: Both the main part and substitute must utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure mechanical and electrical compatibility with existing printed circuit board layouts.

Circuit Configuration: The substitute must provide dual-channel (2 circuits) current feedback amplifier functionality to maintain functional equivalence.

Supply Voltage Range: The substitute must operate within compatible supply voltage specifications. The EL8108ISZ operates at 5V to 12V (single supply) or ±2.5V to ±6V (dual supply). Substitutes with broader or overlapping voltage ranges are acceptable provided they support the application's required supply configuration.

Bandwidth and Slew Rate: While the EL8108ISZ specifies 200 MHz bandwidth and 800V/µs slew rate, substitutes with equal or superior performance in these parameters maintain functional compatibility.

Output Current Capability: The EL8108ISZ provides 450 mA per channel output current. Substitutes with equal or greater output current capability are functionally compatible.

Regulatory Compliance: Substitutes must maintain ROHS3 compliance and REACH unaffected status to satisfy environmental and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The AD812ARZ manufactured by Analog Devices Inc. is an active production substitute for the obsolete EL8108ISZ. Both devices share identical package specifications (8-SOIC), dual-channel configuration, and regulatory compliance status (ROHS3 compliant, REACH unaffected).

The AD812ARZ provides superior performance characteristics in slew rate (1600V/µs versus 800V/µs) and operates across a broader supply voltage range (2.4V to 36V single supply, ±1.2V to ±18V dual supply), which encompasses the EL8108ISZ operating range. The AD812ARZ also demonstrates lower supply current consumption (4.5 mA versus 14.3 mA).

The primary design consideration is output current capability. The AD812ARZ provides 50 mA per channel output current, compared to the EL8108ISZ specification of 450 mA per channel. Applications requiring the full 450 mA output current per channel must evaluate whether the AD812ARZ output current specification is sufficient for the intended circuit function.

The AD812ARZ maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete EL8108ISZ.

Frequently Asked Questions (FAQ)

Q: Can the AD812ARZ directly replace the EL8108ISZ in existing circuit designs?

A: The AD812ARZ shares the same 8-SOIC package and dual-channel current feedback amplifier configuration, enabling direct physical and functional substitution in most applications. However, the reduced output current specification (50 mA per channel versus 450 mA per channel) must be evaluated against circuit load requirements. Applications not requiring the full 450 mA output current per channel are fully compatible.

Q: What is the significance of the broader supply voltage range in the AD812ARZ?

A: The AD812ARZ operates across 2.4V to 36V (single supply) or ±1.2V to ±18V (dual supply), compared to the EL8108ISZ range of 5V to 12V or ±2.5V to ±6V. This broader range provides design flexibility and accommodates a wider variety of power supply configurations. The EL8108ISZ operating range is fully contained within the AD812ARZ specification.

Q: Why does the AD812ARZ have a lower -3dB bandwidth than the EL8108ISZ?

A: The AD812ARZ specifies 145 MHz bandwidth compared to the EL8108ISZ specification of 200 MHz. Applications requiring bandwidth exceeding 145 MHz must verify that the AD812ARZ bandwidth specification is adequate for the intended signal frequency range.

Q: What does the Moisture Sensitivity Level (MSL) difference indicate?

A: The EL8108ISZ specifies MSL 3 (168 hours), while the AD812ARZ specifies MSL 1 (unlimited). MSL 1 indicates superior moisture resistance and less stringent handling requirements during storage and assembly. The AD812ARZ provides more favorable moisture sensitivity characteristics.

Q: Are both devices compliant with current environmental regulations?

A: Both the EL8108ISZ and AD812ARZ are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the primary reason to transition from EL8108ISZ to AD812ARZ?

A: The EL8108ISZ is classified as obsolete and no longer in active production. The AD812ARZ is an active production component from Analog Devices Inc., ensuring long-term availability, supply chain continuity, and access to current manufacturing processes and quality standards.
