Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPA860IDRG4 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Amplifier type (Transconductance)
• Number of circuits (1)
• Slew rate (3500 V/µs)
• Gain bandwidth product (470 MHz)
• Input bias current (1 µA)
• Input offset voltage (3 mV)
• Supply current (11.2 mA)
• Supply voltage range (4.5 V to 12 V)
• Operating temperature range (-40°C to 85°C)

Mechanical Specifications:

• Package type (8-SOIC)
• Package dimensions (0.154", 3.90 mm width)
• Mounting type (Surface Mount)

Compliance & Environmental:

• RoHS3 compliance
• Moisture sensitivity level (MSL 2)

The OPA860IDR meets all these criteria and serves as a direct functional equivalent. The primary distinction is packaging format: OPA860IDRG4 is supplied in tube packaging, while OPA860IDR is supplied in Tape & Reel (TR) format. Both devices are manufactured by Texas Instruments and share identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The OPA860IDR is the direct substitute for the OPA860IDRG4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The OPA860IDR is recommended for new designs and procurement due to its active product status.

Compliance Considerations: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 2, 1 Year), ensuring compatibility with standard manufacturing and storage protocols.

Packaging Consideration: The primary difference between these parts is the packaging format. The OPA860IDRG4 is supplied in tube packaging, while the OPA860IDR is supplied in Tape & Reel (TR) format. This distinction affects procurement quantities and automated assembly compatibility but does not impact electrical performance or functional equivalence.

Inventory & Availability: The OPA860IDR maintains significantly higher inventory availability (4283 pieces in stock) compared to the discontinued OPA860IDRG4 (766 pieces), making it the preferred choice for ongoing production and future orders.

Frequently Asked Questions (FAQ)

Q: Can the OPA860IDR be used as a direct replacement for the OPA860IDRG4 in existing designs?

A: Yes. The OPA860IDR is electrically and mechanically identical to the OPA860IDRG4. All electrical parameters, operating temperature range, supply voltage specifications, and package dimensions are equivalent. The only difference is the packaging format (Tape & Reel versus tube).

Q: What is the difference between OPA860IDRG4 and OPA860IDR?

A: Both parts are identical transconductance amplifiers with the same electrical specifications. The "G4" suffix in OPA860IDRG4 indicates tube packaging, while OPA860IDR is supplied in Tape & Reel (TR) format. This affects how the parts are packaged and delivered but not their performance or functionality.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the OPA860IDRG4 and OPA860IDR maintain identical RoHS3 compliance status and moisture sensitivity levels (MSL 2, 1 Year). They are equivalent from a regulatory and environmental standpoint.

Q: Why is the OPA860IDRG4 discontinued?

A: The OPA860IDRG4 has been discontinued at DiGi Electronics. The OPA860IDR remains in active production and is the recommended part for current and future applications.

Q: Can I use OPA860IDR in automated pick-and-place assembly?

A: Yes. The OPA860IDR is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly processes. The 8-SOIC package is compatible with standard pick-and-place equipment.

Q: What are the key electrical parameters that define substitution for this part?

A: Substitution is determined by matching the transconductance amplifier type, single circuit configuration, 470 MHz gain bandwidth product, 3500 V/µs slew rate, 1 µA input bias current, 3 mV input offset voltage, 11.2 mA supply current, and 4.5 V to 12 V supply voltage range. The 8-SOIC package and surface mount configuration are also critical for mechanical compatibility.
