Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1013MDREP is determined by equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Amplifier type classification (General Purpose)
• Number of circuits (2)
• Slew rate (0.4 V/µs)
• Gain bandwidth product (1 MHz)
• Input bias current (15 nA)
• Input offset voltage (60 µV)
• Supply current per channel (350 µA)

Mechanical & Environmental Compatibility:

• Package type (8-SOIC surface mount)
• Physical dimensions (0.154", 3.90mm width)
• Moisture sensitivity level (MSL 1)
• RoHS3 compliance

Supply Voltage Compatibility: The LT1013MDREP operates within a 5V to 30V supply range. Substitute parts must support the minimum supply voltage requirement of 5V for direct replacement in existing designs.

The LT1013IS8#PBF, manufactured by Analog Devices Inc., meets all functional and mechanical equivalence criteria and is classified as an active product, providing long-term availability for production applications.

Parameter Comparison

Engineering Selection Recommendations

The LT1013IS8#PBF is the manufacturer-recommended substitute for the obsolete LT1013MDREP. Both components share the same base product number (LT1013) and are manufactured to identical functional specifications for the core amplifier characteristics.

Compliance & Certification Alignment: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards. The LT1013IS8#PBF carries active product status from Analog Devices Inc., providing assured long-term availability and supply chain continuity.

Parameter Deviations: The LT1013IS8#PBF exhibits the following rated parameter differences:

• Output current per channel is rated at 20 mA versus 25 mA on the original part
• Minimum supply voltage is rated at 4V versus 5V on the original part
• Maximum supply voltage is rated at 44V versus 30V on the original part
• Operating temperature range is -40°C to 85°C versus -55°C to 125°C on the original part

These deviations do not preclude substitution in applications operating within the substitute part's specified limits. Design verification is required only when applications demand the extended temperature range (-55°C to -40°C or 85°C to 125°C) or output current exceeding 20 mA per channel.

Frequently Asked Questions (FAQ)

Q: Can the LT1013IS8#PBF directly replace the LT1013MDREP in existing PCB designs?

A: Yes. Both components use identical 8-SOIC package geometry (0.154", 3.90mm width) and pinout configuration. No PCB layout modifications are required for mechanical or electrical compatibility at the package level.

Q: What are the key functional differences between these parts?

A: The core amplifier specifications are identical: 1 MHz gain-bandwidth product, 0.4 V/µs slew rate, 15 nA input bias current, and 60 µV input offset voltage. Differences exist only in rated output current per channel (20 mA vs. 25 mA), supply voltage range limits, and operating temperature range.

Q: Is the LT1013IS8#PBF suitable for applications requiring the full -55°C to 125°C temperature range?

A: No. The LT1013IS8#PBF is rated for -40°C to 85°C operation. Applications requiring operation below -40°C or above 85°C must retain the original LT1013MDREP or identify alternative components with extended temperature specifications.

Q: What is the significance of the packaging designation change from "Tape & Reel (TR)" to "Tube"?

A: This reflects the supplier packaging format rather than a component specification change. Tape & Reel packaging is optimized for automated assembly processes, while Tube packaging is suitable for manual handling and lower-volume applications. Both formats contain identical components in the same 8-SOIC package.

Q: Are there supply chain advantages to using the LT1013IS8#PBF?

A: Yes. The LT1013IS8#PBF carries active product status from Analog Devices Inc., ensuring continued manufacturing and distribution. The LT1013MDREP is classified as obsolete, indicating discontinued production and limited remaining inventory.

Q: Can the LT1013IS8#PBF be used in applications requiring 25 mA output current per channel?

A: The LT1013IS8#PBF is rated for 20 mA maximum output current per channel. Applications requiring 25 mA output current must either operate within the 20 mA limit or identify alternative components with higher output current ratings.

Q: Do both parts meet current environmental and compliance standards?

A: Yes. Both the LT1013MDREP and LT1013IS8#PBF are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current manufacturing and environmental requirements.
