EL8176FSZ Equivalent & Substitute Parts

Part Overview

The EL8176FSZ is a general-purpose operational amplifier manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability and is designed for low-power analog signal processing applications. The EL8176FSZ is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and production continuity. Substitute parts must maintain functional compatibility across critical electrical parameters including supply voltage range, output current capability, and operating temperature specifications.

Substitute Part Grouping Explanation

Substitute parts for the EL8176FSZ are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical specifications across all critical parameters. These parts are direct replacements with no performance trade-offs:

EL8176FSZ (Elantec, Bulk packaging)
EL8176FSZ-T7 (Elantec, Bulk packaging)

Functional Substitutes provide rail-to-rail general-purpose amplification in the same 8-SOIC package with compatible supply voltage ranges and operating temperatures. These parts accept the same pinout and package footprint but exhibit enhanced electrical performance characteristics:

TSV911IDT (STMicroelectronics, Cut Tape & Digi-Reel)
TSV911AIDT (STMicroelectronics, Cut Tape & Digi-Reel)
TSV911IYDT (STMicroelectronics, Tape & Reel, Automotive Grade)

Substitution eligibility is determined by the following mandatory parameters:

Package type: 8-SOIC surface mount
Output configuration: Rail-to-rail
Supply voltage range: Minimum 2.4 V to 2.5 V; Maximum 5.5 V
Operating temperature range: -40°C to 125°C

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

The EL8176FSZ variants manufactured by Elantec (EL8176FSZ and EL8176FSZ-T7) are parametric equivalents with identical electrical specifications. Both parts are currently in active production status, providing immediate availability for designs requiring exact performance matching. The EL8176FSZ-T7 variant offers higher inventory levels (3,759 units) compared to the standard EL8176FSZ (3,025 units). Selection between these two Elantec variants depends solely on packaging preference and inventory requirements, as electrical performance is identical.

For Functional Substitution (Enhanced Performance):

The TSV911 series operational amplifiers from STMicroelectronics provide functional substitution with enhanced electrical performance. All three TSV911 variants (TSV911IDT, TSV911AIDT, TSV911IYDT) are in active production status and maintain compatibility across package, supply voltage range, and operating temperature specifications. These parts exhibit superior performance characteristics including 20× higher slew rate (4.5 V/µs versus 0.13 V/µs), 20× higher gain bandwidth product (8 MHz versus 400 kHz), and significantly lower input bias current (1 pA versus 500 pA).

The TSV911IYDT variant includes automotive-grade qualification (AEC-Q100) and is supplied in Tape & Reel packaging, making it suitable for high-volume automotive applications. The TSV911IDT and TSV911AIDT variants are supplied in Cut Tape & Digi-Reel packaging and are suitable for general industrial and commercial applications.

All TSV911 variants feature improved moisture sensitivity (MSL 1, Unlimited versus MSL 3, 168 Hours), reducing handling and storage constraints during manufacturing.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original EL8176FSZ specification. The TSV911 series provides superior compliance characteristics with unlimited moisture sensitivity rating, reducing risk during extended storage or humid manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the TSV911 series directly replace the EL8176FSZ in existing designs?

A: The TSV911 series provides functional substitution with identical package, pinout, and supply voltage compatibility. However, the enhanced electrical performance (higher slew rate, bandwidth, and lower input bias current) may alter circuit behavior in applications with tight timing or precision requirements. Circuit validation is necessary when substituting from EL8176FSZ to TSV911 variants.

Q: What is the difference between the Elantec EL8176FSZ variants and the STMicroelectronics TSV911 series?

A: The Elantec variants (EL8176FSZ and EL8176FSZ-T7) are parametric equivalents with identical electrical specifications to the original Renesas EL8176FSZ. The STMicroelectronics TSV911 series provides enhanced performance with 20× higher slew rate and gain bandwidth product. Selection depends on whether exact performance matching or enhanced performance is required.

Q: Is the TSV911IYDT suitable for automotive applications?

A: Yes. The TSV911IYDT is qualified to AEC-Q100 automotive standards and is specifically designed for automotive-grade applications. The TSV911IDT and TSV911AIDT variants are not automotive-qualified and are suitable for industrial and commercial applications only.

Q: What packaging options are available for substitute parts?

A: The Elantec variants are supplied in Bulk packaging. The STMicroelectronics TSV911IDT and TSV911AIDT are supplied in Cut Tape & Digi-Reel packaging. The TSV911IYDT is supplied in Tape & Reel packaging. Package selection depends on production volume and assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (Elantec EL8176FSZ variants and STMicroelectronics TSV911 series) are ROHS3 compliant. The original Renesas EL8176FSZ is also ROHS3 compliant.

Q: What is the moisture sensitivity difference between the main part and substitutes?

A: The original EL8176FSZ has MSL 3 rating (168 hours maximum floor life). All STMicroelectronics TSV911 variants have MSL 1 rating (unlimited floor life), providing superior moisture tolerance. The Elantec variants do not specify moisture sensitivity rating.

Q: Can I use the TSV911 series in low-power applications where the EL8176FSZ was originally specified?

A: The TSV911 series has higher supply current (820 µA versus 55 µA). In battery-powered or ultra-low-power applications, this increased current consumption may be unacceptable. The Elantec EL8176FSZ variants maintain the original 55 µA supply current specification and are preferred for power-constrained designs.

Q: What is the inventory status of each substitute part?

A: Elantec EL8176FSZ: 3,025 units. Elantec EL8176FSZ-T7: 3,759 units. STMicroelectronics TSV911IDT: 18,229 units. STMicroelectronics TSV911AIDT: 25,200 units. STMicroelectronics TSV911IYDT: 20,186 units. The TSV911 series offers significantly higher inventory availability.
