OP113ES Equivalent & Substitute Parts

Part Overview

The OP113ES is a general-purpose operational amplifier manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and production continuity. The OP113ES delivers a gain-bandwidth product of 3.4 MHz with a slew rate of 1.2 V/µs, suitable for general-purpose amplification applications requiring moderate bandwidth and low input offset voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP113ES is determined by electrical and mechanical compatibility across the following critical parameters: package type (8-SOIC surface mount), supply voltage range (4 V to 36 V minimum), operating temperature range (-40°C to 85°C minimum), and functional amplifier classification. The OP113ES operates as a general-purpose amplifier with defined slew rate (1.2 V/µs) and gain-bandwidth product (3.4 MHz) characteristics.

Two substitute parts are identified:

OP113ESZ (Analog Devices Inc.) — Direct equivalent with identical electrical specifications and package configuration. This part maintains the same base product number (OP113) and represents an active-status variant with tube packaging, offering direct functional replacement.

OPA180IDR (Texas Instruments) — Similar amplifier classification with compatible package and supply voltage specifications. This zero-drift amplifier variant operates within the OP113ES supply voltage range and package footprint, though with different amplifier type classification and enhanced input offset voltage performance.

Parameter Comparison

Engineering Selection Recommendations

OP113ESZ is the primary substitute for OP113ES applications. Both parts share identical electrical specifications, the same 8-SOIC package footprint, and equivalent supply voltage operating ranges. OP113ESZ maintains active product status with ROHS3 compliance and REACH unaffected certification, ensuring regulatory alignment and long-term availability. This part provides direct functional replacement without circuit redesign requirements.

OPA180IDR serves as an alternative substitute where enhanced input offset voltage performance (15 µV versus 75 µV) and reduced input bias current (250 pA versus 240 nA) are beneficial. The OPA180IDR operates within the OP113ES supply voltage envelope and shares the 8-SOIC package configuration. However, the OPA180IDR exhibits lower slew rate (0.8 V/µs versus 1.2 V/µs) and reduced gain-bandwidth product (2 MHz versus 3.4 MHz), requiring circuit performance verification for bandwidth-sensitive applications. The OPA180IDR features extended operating temperature range (-40°C to 105°C) and active product status with ROHS3 compliance.

Selection between OP113ESZ and OPA180IDR depends on application-specific requirements for bandwidth, slew rate, and input offset voltage performance. OP113ESZ provides direct electrical equivalence; OPA180IDR provides enhanced precision characteristics with bandwidth trade-offs.

Frequently Asked Questions (FAQ)

Q: Can OP113ESZ directly replace OP113ES without circuit modification?

A: Yes. OP113ESZ maintains identical electrical specifications, supply voltage range, operating temperature range, and 8-SOIC package configuration as OP113ES. Direct substitution is supported without circuit redesign.

Q: What are the key differences between OP113ESZ and OPA180IDR?

A: OP113ESZ is a direct electrical equivalent to OP113ES with identical slew rate (1.2 V/µs) and gain-bandwidth product (3.4 MHz). OPA180IDR is a zero-drift amplifier with lower slew rate (0.8 V/µs), reduced gain-bandwidth product (2 MHz), but superior input offset voltage (15 µV versus 75 µV) and input bias current performance. Both share 8-SOIC packaging and compatible supply voltage ranges.

Q: Is OPA180IDR suitable for high-bandwidth applications?

A: OPA180IDR exhibits reduced bandwidth characteristics (2 MHz gain-bandwidth product, 0.8 V/µs slew rate) compared to OP113ES (3.4 MHz, 1.2 V/µs). Applications requiring the full bandwidth performance of OP113ES should use OP113ESZ or verify OPA180IDR performance through circuit simulation.

Q: What is the minimum supply voltage for each substitute?

A: OP113ES and OP113ESZ operate at minimum 4 V supply voltage. OPA180IDR requires minimum 4.5 V supply voltage. Circuit designs operating below 4.5 V must use OP113ESZ.

Q: Are all substitute parts RoHS and REACH compliant?

A: OP113ESZ and OPA180IDR are both ROHS3 compliant and REACH unaffected. OP113ES compliance status is not specified in available documentation.

Q: What is the moisture sensitivity difference between substitutes?

A: OP113ES and OP113ESZ carry MSL 1 (Unlimited) rating. OPA180IDR carries MSL 2 (1 Year) rating, requiring stricter moisture control during storage and handling.

Q: Can these parts be used interchangeably in existing PCB designs?

A: All three parts share identical 8-SOIC package footprint (0.154", 3.90mm width) and surface-mount configuration, enabling direct PCB placement compatibility. Electrical performance differences require application-specific verification.
