• Number of Circuits: 1
• Package / Case: SOT-23-6
• Mounting Type: Surface Mount
• Voltage - Supply Span: 5V to 12V
• Operating Temperature Range: -40°C to 85°C
• RoHS Status: ROHS3 Compliant

Secondary Performance Alignment:

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

The substitute parts listed below maintain compatibility within these electrical and mechanical boundaries. Parts are grouped by manufacturer and product status to facilitate selection based on availability and lifecycle requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: OPA695IDBVR

The OPA695IDBVR is the direct equivalent to the OPA695IDBVRG4, manufactured by Texas Instruments with identical electrical specifications and SOT-23-6 packaging. This part maintains active product status and is available in higher inventory quantities (31,300 pcs). The OPA695IDBVR is ROHS3 compliant and carries MSL 1 rating, matching the original part's environmental specifications. Selection of OPA695IDBVR is recommended as the primary replacement for discontinued OPA695IDBVRG4 applications.

Secondary Substitutes: EL5164IWZ-T7, EL5164IWZ-T7A, EL5166IWZ-T7, EL5166IWZ-T7A

These Renesas Electronics Corporation parts are current feedback amplifiers in SOT-23-6 packages with 5V to 12V supply compatibility and -40°C to 85°C operating range. All are ROHS3 compliant. However, these parts carry obsolete product status and MSL 2 rating (1 Year moisture sensitivity), differing from the original part's unlimited MSL specification. Selection of these parts is appropriate only when OPA695IDBVR availability is constrained and design requirements accommodate the reduced bandwidth specifications of EL5164 variants (0.6 GHz) or the lower input bias current of EL5164 (2 µA) and EL5166 (8.5 µA) compared to the original 20 µA specification.

Frequently Asked Questions (FAQ)

Q: Can OPA695IDBVR directly replace OPA695IDBVRG4 without circuit modification?

A: Yes. The OPA695IDBVR is electrically and mechanically identical to OPA695IDBVRG4. Both devices share identical slew rate (4300V/µs), bandwidth (1.7 GHz), supply voltage range (5V to 12V), operating temperature (-40°C to 85°C), and SOT-23-6 packaging. No circuit redesign is required.

Q: What are the key differences between OPA695IDBVR and EL5166IWZ-T7A?

A: The primary differences are: (1) Slew Rate—OPA695IDBVR delivers 4300V/µs versus EL5166IWZ-T7A at 6000V/µs; (2) -3dB Bandwidth—OPA695IDBVR provides 1.7 GHz versus EL5166IWZ-T7A at 1.4 GHz; (3) Input Bias Current—OPA695IDBVR specifies 20 µA versus EL5166IWZ-T7A at 8.5 µA; (4) Product Status—OPA695IDBVR is active while EL5166IWZ-T7A is obsolete; (5) MSL Rating—OPA695IDBVR is MSL 1 (unlimited) while EL5166IWZ-T7A is MSL 2 (1 year). These differences may affect circuit performance in high-frequency or precision applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—OPA695IDBVR, EL5164IWZ-T7, EL5164IWZ-T7A, EL5166IWZ-T7, and EL5166IWZ-T7A—carry ROHS3 compliance certification, matching the original OPA695IDBVRG4 specification.

Q: What is the significance of MSL rating differences?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be stored in ambient conditions before requiring baking prior to reflow soldering. OPA695IDBVRG4 and OPA695IDBVR carry MSL 1 (unlimited storage), while Renesas substitutes carry MSL 2 (1 year maximum). MSL 2 components require moisture control during storage and handling to prevent solder joint degradation during assembly.

Q: Can EL5164IWZ-T7 substitute for OPA695IDBVRG4 in all applications?

A: EL5164IWZ-T7 is compatible within the SOT-23-6 package and 5V to 12V supply range. However, the -3dB bandwidth is reduced from 1.7 GHz to 0.6 GHz, and input bias current is reduced from 20 µA to 2 µA. Applications requiring the full 1.7 GHz bandwidth of the original part will not function correctly with EL5164IWZ-T7. Verification of bandwidth requirements is necessary before substitution.

Q: What inventory considerations apply to these substitutes?

A: OPA695IDBVR offers the highest inventory availability (31,300 pcs) and active product status, making it the most reliable long-term supply source. Renesas parts (EL5164 and EL5166 variants) carry lower inventory levels (910 to 4,122 pcs) and obsolete product status, indicating limited future availability. For production planning, OPA695IDBVR is the recommended choice.
