EL5178ISZ Equivalent & Substitute Parts

Part Overview

The EL5178ISZ is a differential amplifier integrated circuit manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface mount package. This device functions as a single-circuit differential amplifier with differential output configuration, designed for linear signal processing applications requiring high-speed amplification.

The EL5178ISZ carries an obsolete product status. Locating equivalent substitute parts is necessary to support ongoing system maintenance, design revisions, and production continuity where original inventory becomes depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EL5178ISZ is determined by strict alignment across the following critical parameters:

Mandatory Matching Criteria:

• Amplifier Type: Differential
• Number of Circuits: 1
• Output Type: Differential
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply Span (Min): 4.75 V
• Voltage - Supply Span (Max): 11 V
• Operating Temperature Range: -40°C to 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Allowable Parameter Variation: Substitute parts may exhibit differences in slew rate, gain bandwidth product, -3dB bandwidth, input bias current, input offset voltage, and supply current, provided all mandatory criteria remain identical. These performance parameters define application-specific suitability but do not preclude functional substitution at the component level.

The EL5174ISZ meets all mandatory matching criteria and qualifies as a valid substitute for the EL5178ISZ.

Parameter Comparison

Engineering Selection Recommendations

Both the EL5178ISZ and EL5174ISZ are obsolete products manufactured by Renesas Electronics Corporation. Both devices carry ROHS3 compliance and identical moisture sensitivity ratings, confirming regulatory and environmental handling equivalence.

The EL5174ISZ presents higher slew rate performance (1100 V/µs versus 850 V/µs) and lower input offset voltage (1.4 mV versus 1.9 mV), while the EL5178ISZ provides higher gain bandwidth product (350 MHz versus 200 MHz) and -3dB bandwidth (700 MHz versus 550 MHz). Selection between these parts depends on application-specific requirements for transient response speed versus bandwidth characteristics.

Both devices operate across identical supply voltage ranges (4.75 V to 11 V) and temperature ranges (-40°C to 85°C), with matching input bias current and supply current specifications. Pin-compatible 8-SOIC surface mount packaging ensures mechanical and electrical interchangeability at the board level.

Frequently Asked Questions (FAQ)

Q: Can the EL5174ISZ directly replace the EL5178ISZ in existing designs?

A: Yes. Both devices share identical package geometry (8-SOIC), mounting type (surface mount), supply voltage ranges (4.75 V to 11 V), operating temperature range (-40°C to 85°C), and functional classification (single-circuit differential amplifier with differential output). Pin-level compatibility is established.

Q: What performance differences exist between these parts?

A: The EL5174ISZ exhibits higher slew rate (1100 V/µs versus 850 V/µs) and lower input offset voltage (1.4 mV versus 1.9 mV). The EL5178ISZ provides higher gain bandwidth product (350 MHz versus 200 MHz) and -3dB bandwidth (700 MHz versus 550 MHz). Input bias current and supply current remain identical at 14 µA and 12.5 mA respectively.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Both the EL5178ISZ and EL5174ISZ are ROHS3 compliant and carry REACH unaffected status. Both devices maintain identical moisture sensitivity level ratings (MSL 3, 168 hours), confirming equivalent handling and storage requirements.

Q: What is the significance of the obsolete product status?

A: Obsolete status indicates these devices are no longer in active production by Renesas Electronics Corporation. Availability is limited to existing inventory channels. Substitution between EL5178ISZ and EL5174ISZ supports design continuity and production scheduling when original part numbers become unavailable.

Q: How do supply voltage and temperature specifications compare?

A: Both parts operate identically across supply voltage ranges of 4.75 V minimum to 11 V maximum, and temperature ranges of -40°C to 85°C. These specifications are fully interchangeable for system-level integration.

Q: Which part should be selected for high-speed transient applications?

A: Application requirements determine selection. The EL5174ISZ provides superior slew rate performance (1100 V/µs) for fast transient response. The EL5178ISZ provides higher bandwidth (700 MHz -3dB bandwidth) for sustained high-frequency signal processing. Both are valid depending on circuit requirements.
