LT1014DMDWREP Equivalent & Substitute Parts

Part Overview

The LT1014DMDWREP is a general-purpose operational amplifier integrated circuit manufactured by Texas Instruments, configured as a 4-circuit device in a 16-SOIC surface mount package. This component is designed for applications requiring low input bias current, low input offset voltage, and operation across an extended supply voltage range. The part maintains Active product status with 2780 units in current inventory stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this amplifier category. Substitution becomes necessary due to supply availability, packaging preferences, or procurement requirements while maintaining circuit functionality and performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LT1014DMDWREP is determined by strict alignment with the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: General Purpose (4-circuit configuration required)
• Slew Rate: 0.4 V/µs (matching specification)
• Gain Bandwidth Product: 1 MHz (matching specification)
• Input Bias Current: 15 nA (matching specification)
• Supply Voltage Range: 4 V to 44 V (minimum and maximum must be met or exceeded)

Mechanical Compatibility Criteria:

• Package Type: 16-SOIC surface mount configuration
• Pin Count: 16 pins
• Physical Dimensions: 0.295" × 7.50mm width

Compliance & Status Criteria:

• Product Status: Active
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part LT1014DSW#TRPBF meets these core substitution parameters while maintaining functional equivalence within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

Primary Part Selection (LT1014DMDWREP): Select the LT1014DMDWREP when applications require the extended operating temperature range of -55°C to 125°C, higher output current capability (25 mA per channel), or lower supply current consumption (300 µA total). This part is suitable for industrial, automotive, and military-grade applications with demanding thermal specifications. Active product status and ROHS3 compliance confirm ongoing manufacturing support and environmental regulatory alignment.

Substitute Part Selection (LT1014DSW#TRPBF): The LT1014DSW#TRPBF serves as an electrical and mechanical substitute when operating temperature requirements fall within the 0°C to 70°C range and output current requirements do not exceed 20 mA per channel. This substitute maintains all critical electrical parameters (slew rate, gain bandwidth product, input bias current, and supply voltage range) and identical package geometry. The substitute offers tighter input offset voltage specification (60 µV versus 90 µV), which may provide improved precision in applications sensitive to DC offset. Tape & Reel packaging format supports high-volume automated assembly processes.

Compliance Verification: Both parts maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), confirming suitability for standard PCB assembly and storage conditions without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can LT1014DSW#TRPBF replace LT1014DMDWREP in all applications?

A: Substitution is valid only when the application operating temperature range does not exceed 0°C to 70°C. If your circuit operates below 0°C or above 70°C, the LT1014DMDWREP is required. Additionally, if output current per channel must reach 25 mA, the main part is necessary; the substitute is limited to 20 mA per channel.

Q: What is the significance of the different input offset voltage specifications?

A: The LT1014DSW#TRPBF specifies 60 µV input offset voltage compared to 90 µV for the LT1014DMDWREP. This represents a tighter specification on the substitute part, meaning lower DC offset error. For applications with relaxed offset requirements, both parts are functionally equivalent. For precision instrumentation requiring minimal offset, the substitute may provide superior performance.

Q: Are the packages physically identical?

A: Both parts use 16-SOIC surface mount packages with identical physical dimensions (0.295" × 7.50mm width) and pin configurations. PCB layout and footprints are directly compatible. The difference lies in packaging format: the main part uses tube packaging, while the substitute uses Tape & Reel format for automated assembly.

Q: What is the impact of higher supply current in the substitute part?

A: The LT1014DSW#TRPBF draws 350 µA total supply current versus 300 µA for the LT1014DMDWREP. This 50 µA difference per device is typically negligible in most applications but should be considered in battery-powered or power-constrained designs where cumulative current consumption is critical.

Q: Are both parts suitable for RoHS-compliant applications?

A: Yes. Both the LT1014DMDWREP and LT1014DSW#TRPBF carry ROHS3 compliance certification, confirming they meet restricted substance requirements for lead-free and hazardous material elimination in electronic equipment manufacturing.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Both parts can be stored and handled under standard warehouse conditions without requiring special dry-pack storage, desiccant, or baking procedures prior to assembly. This simplifies inventory management and reduces handling costs.
