OPA690IDBVRG4 Equivalent & Substitute Parts

Part Overview

The OPA690IDBVRG4 is a voltage feedback operational amplifier manufactured by Texas Instruments, housed in a SOT-23-6 surface mount package. This device is classified as a linear amplifier with single-circuit configuration, designed for high-speed signal processing applications requiring 300 MHz gain bandwidth product and 1800 V/µs slew rate.

The OPA690IDBVRG4 is currently discontinued at DiGi Electronics. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Substitute components must maintain electrical compatibility across critical parameters including supply voltage range, slew rate, bandwidth, and thermal operating conditions.

Substitute Part Grouping Explanation

Substitution of the OPA690IDBVRG4 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type: Voltage Feedback
• Number of Circuits: 1
• Package / Case: SOT-23-6
• Mounting Type: Surface Mount
• Voltage - Supply Span: 5 V (Min) to 12 V (Max)
• Operating Temperature Range: -40°C to 85°C
• RoHS3 Compliance and MSL 2 rating

Secondary Performance Parameters:

• Slew Rate: 1800 V/µs
• Gain Bandwidth Product: 300 MHz
• -3dB Bandwidth: 500 MHz
• Current - Input Bias: 3 µA
• Voltage - Input Offset: 1 mV
• Current - Supply: 5.5 mA
• Current - Output / Channel: 190 mA

Substitute parts are grouped into two categories:

Category 1: Manufacturer Recommended Equivalent (OPA690IDBVR) Identical electrical specifications and package configuration. Active product status with full inventory availability. Direct pin-for-pin replacement.

Category 2: Parametric Equivalent (OPA690IDBVT) Identical electrical specifications and package configuration. Last Time Buy status with limited inventory. Direct pin-for-pin replacement with supply constraints.

Category 3: Cross-Manufacturer Alternative (EL5106IWZ-T7A) General Purpose Amplifier from Renesas Electronics. Meets package, supply voltage, and temperature requirements. Performance parameters differ in slew rate (4500 V/µs), -3dB bandwidth (380 MHz), and supply current (1.5 mA). Obsolete product status. Substitution requires circuit-level evaluation.

Engineering Selection Recommendations

Primary Selection: OPA690IDBVR

The OPA690IDBVR is the recommended substitute for the discontinued OPA690IDBVRG4. This part maintains identical electrical specifications, package configuration, and compliance certifications. The OPA690IDBVR holds Active product status with 28,945 pieces in stock, ensuring supply chain continuity and long-term availability. Both parts are ROHS3 compliant with MSL 2 rating. Pin-for-pin compatibility is confirmed. No circuit modifications are required.

Secondary Selection: OPA690IDBVT

The OPA690IDBVT provides parametric equivalence with identical electrical specifications and package configuration. This part is designated Last Time Buy status with 2,134 pieces available. Use this substitute only when OPA690IDBVR inventory is unavailable. Both parts are ROHS3 compliant with MSL 2 rating. Pin-for-pin compatibility is confirmed. No circuit modifications are required.

Alternative Selection: EL5106IWZ-T7A

The EL5106IWZ-T7A from Renesas Electronics is a cross-manufacturer alternative suitable only for applications where performance parameter variations are acceptable. This part is Obsolete with 4,122 pieces in stock. Key differences include higher slew rate (4500 V/µs versus 1800 V/µs), lower -3dB bandwidth (380 MHz versus 500 MHz), reduced supply current (1.5 mA versus 5.5 mA), and lower output current capability (100 mA versus 190 mA). Pin-for-pin compatibility is confirmed. Circuit-level evaluation is required before substitution. ROHS3 compliance and MSL 2 rating are maintained.

Frequently Asked Questions (FAQ)

Q1: Can OPA690IDBVR be used as a direct replacement for OPA690IDBVRG4?

Yes. The OPA690IDBVR is a direct pin-for-pin replacement with identical electrical specifications, package configuration (SOT-23-6), supply voltage range (5 V to 12 V), operating temperature range (-40°C to 85°C), and compliance certifications (ROHS3, MSL 2). No circuit modifications are required.

Q2: What is the difference between OPA690IDBVR and OPA690IDBVT?

Both parts are electrically identical with matching specifications and package configuration. The primary difference is product status: OPA690IDBVR is Active with higher inventory availability (28,945 pieces), while OPA690IDBVT is Last Time Buy with limited inventory (2,134 pieces). Select OPA690IDBVR for new designs and ongoing production.

Q3: Is EL5106IWZ-T7A a suitable substitute for OPA690IDBVRG4?

The EL5106IWZ-T7A meets package and supply voltage requirements but exhibits performance differences. Slew rate is higher (4500 V/µs versus 1800 V/µs), -3dB bandwidth is lower (380 MHz versus 500 MHz), supply current is lower (1.5 mA versus 5.5 mA), and output current capability is reduced (100 mA versus 190 mA). This part is Obsolete. Substitution requires circuit-level evaluation and is not recommended for new designs.

Q4: Are all substitute parts ROHS3 compliant?

Yes. OPA690IDBVR, OPA690IDBVT, and EL5106IWZ-T7A are all ROHS3 compliant with MSL 2 (1 Year) rating. All parts meet environmental and regulatory requirements for industrial and commercial applications.

Q5: What is the recommended inventory strategy for OPA690IDBVRG4 replacement?

Transition to OPA690IDBVR for all new designs and ongoing production. This part is Active with robust inventory (28,945 pieces) and ensures long-term supply availability. OPA690IDBVT may be used as a secondary source when OPA690IDBVR is temporarily unavailable, but inventory is limited (2,134 pieces). Avoid EL5106IWZ-T7A for new designs due to Obsolete status and performance parameter variations.

Q6: Can these parts be used interchangeably in existing PCB designs?

Yes, for OPA690IDBVR and OPA690IDBVT. Both parts are pin-for-pin compatible with identical package configuration (SOT-23-6) and electrical specifications. No PCB modifications are required. EL5106IWZ-T7A is also pin-for-pin compatible but requires circuit-level evaluation due to performance differences.

Q7: What are the key parameters that determine substitution compatibility?

Substitution compatibility is determined by: package type (SOT-23-6), supply voltage range (5 V to 12 V), operating temperature range (-40°C to 85°C), amplifier type (Voltage Feedback), circuit count (1), and compliance certifications (ROHS3, MSL 2). Secondary parameters include slew rate, bandwidth, input bias current, and output current capability.
