Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPA695IDBVT is determined by the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type: Current Feedback
• Number of Circuits: 1
• Package / Case: SOT-23-6
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 85°C
• Voltage Supply Span: 5 V to 12 V

Performance Compatibility Parameters:

• Slew Rate: 4300 V/µs or higher
• -3dB Bandwidth: 1.7 GHz or higher
• Current - Output / Channel: 120 mA or higher

Substitute parts must maintain electrical compatibility within the specified supply voltage range and operating temperature window. Parts are grouped based on whether they meet or exceed the OPA695IDBVT performance specifications while maintaining identical or compatible package configurations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: OPA695IDBVR

The OPA695IDBVR is the direct equivalent to the OPA695IDBVT. Both devices are manufactured by Texas Instruments with identical electrical specifications, package configuration, and operating parameters. The OPA695IDBVR holds Active product status with significantly higher inventory availability (31,300 pieces), making it the preferred substitute for immediate and long-term supply requirements. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. This substitution requires no circuit redesign or performance verification.

Secondary Substitutes: EL5166IWZ-T7 and EL5166IWZ-T7A

The EL5166IWZ-T7 and EL5166IWZ-T7A are Renesas Electronics current feedback amplifiers in SOT-23-6 packages. These devices exceed the OPA695IDBVT performance specifications with 6000 V/µs slew rate and 1.4 GHz bandwidth. However, both parts carry Obsolete product status. The EL5166IWZ-T7A provides higher output current capability (200 mA) compared to the OPA695IDBVT (120 mA). These substitutes are suitable only when existing inventory is available and long-term supply is not required.

Tertiary Substitute: EL5164IWZ-T7 and EL5164IWZ-T7A

The EL5164IWZ-T7 and EL5164IWZ-T7A are Renesas Electronics current feedback amplifiers with 4700 V/µs slew rate and 600 MHz bandwidth. These devices provide lower bandwidth than the OPA695IDBVT and are classified as Obsolete. The EL5164IWZ-T7 offers 190 mA output current, exceeding the OPA695IDBVT specification. These parts are suitable only for applications where bandwidth requirements are less stringent than 1.7 GHz.

Not Recommended: EL5106IWZ-T7A

The EL5106IWZ-T7A is classified as a General Purpose amplifier rather than Current Feedback. Its 380 MHz bandwidth falls significantly below the OPA695IDBVT specification of 1.7 GHz. This device is unsuitable for applications requiring the high-speed performance characteristics of the OPA695IDBVT.

Frequently Asked Questions (FAQ)

Q1: Can I directly replace OPA695IDBVT with OPA695IDBVR without circuit modifications?

A: Yes. The OPA695IDBVR is electrically and mechanically identical to the OPA695IDBVT. Both devices share identical specifications for slew rate, bandwidth, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature. The only difference is product status: OPA695IDBVR is Active with higher inventory availability, while OPA695IDBVT is Last Time Buy. No circuit redesign, PCB layout changes, or performance verification are required.

Q2: What is the key difference between Current Feedback and General Purpose amplifier types?

A: Current Feedback amplifiers, such as the OPA695IDBVT and EL5166IWZ-T7, are optimized for high-speed, wideband applications with superior slew rate and bandwidth performance. General Purpose amplifiers, such as the EL5106IWZ-T7A, are designed for lower-speed applications with reduced power consumption. The OPA695IDBVT's 1.7 GHz bandwidth and 4300 V/µs slew rate are characteristic of Current Feedback architecture. Substituting with a General Purpose amplifier will result in performance degradation and is not recommended.

Q3: Why are the Renesas EL5166 and EL5164 devices marked as Obsolete?

A: Obsolete product status indicates that the manufacturer has discontinued production and no longer accepts new orders. While existing inventory may be available, long-term supply cannot be guaranteed. For new designs or long-term production requirements, the Active status OPA695IDBVR is the recommended choice.

Q4: Can I use EL5166IWZ-T7 or EL5166IWZ-T7A if the OPA695IDBVR is unavailable?

A: The EL5166IWZ-T7 and EL5166IWZ-T7A exceed the OPA695IDBVT performance specifications with higher slew rate (6000 V/µs versus 4300 V/µs) and comparable bandwidth (1.4 GHz versus 1.7 GHz). Both devices are pin-compatible in SOT-23-6 packages and operate within the same supply voltage range. However, both are Obsolete products. Use only if existing inventory is confirmed available and supply chain continuity is not critical.

Q5: What does Moisture Sensitivity Level (MSL) mean for component handling?

A: MSL indicates the maximum time a component can be exposed to ambient conditions before soldering. OPA695IDBVT has MSL 1 (Unlimited), meaning no time restrictions. Renesas substitutes have MSL 2 (1 Year), requiring storage in dry conditions and limiting shelf life to one year after packaging. This affects component procurement, storage procedures, and production scheduling.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—OPA695IDBVR, EL5166IWZ-T7, EL5164IWZ-T7, EL5166IWZ-T7A, and EL5106IWZ-T7A—are ROHS3 compliant. This ensures compatibility with environmental regulations and procurement requirements for lead-free manufacturing.

Q7: What is the significance of the SOT-23-6 package for substitution?

A: SOT-23-6 is a standardized surface mount package with six pins in a fixed configuration. All listed substitute parts use identical SOT-23-6 packaging, ensuring mechanical compatibility with existing PCB layouts, footprints, and assembly processes. No PCB redesign is required when substituting between parts with the same package designation.

Q8: Which substitute part offers the best long-term supply availability?

A: The OPA695IDBVR is the only substitute with Active product status and the highest inventory level (31,300 pieces). This part is manufactured by Texas Instruments, the original manufacturer of the OPA695IDBVT, and represents the optimal choice for designs requiring long-term supply continuity and production volume support.
