TL074CDBR Equivalent & Substitute Parts

Part Overview

The TL074CDBR is a J-FET input operational amplifier containing four independent circuits in a 14-SSOP surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The TL074CDBR operates across a wide supply voltage range of 10V to 30V and is suitable for applications requiring low input bias current and stable gain-bandwidth characteristics. Identification of equivalent substitute parts is necessary due to the Last Time Buy status and to ensure continued design support and component availability for production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TL074CDBR are identified based on electrical and mechanical compatibility within the TL074 product family. The substitution criteria are strictly defined by the following parameters:

Electrical Compatibility Parameters:

• Amplifier Type: J-FET input configuration
• Number of Circuits: 4 independent operational amplifiers
• Slew Rate: 13 V/µs
• Gain Bandwidth Product: 5.25 MHz
• Current - Input Bias: 65 pA
• Voltage - Input Offset: 3 mV
• Current - Supply: 1.4 mA (x4 Channels)
• Supply Voltage Range: 10V to 30V
• Operating Temperature Range: 0°C to 70°C

Mechanical Compatibility Parameters:

• Mounting Type: Surface Mount
• Base Product Number: TL074
• RoHS and REACH Compliance: ROHS3 Compliant, REACH Unaffected

Package Variation Allowance: Substitute parts may differ in package type (SSOP versus SOIC) provided all electrical parameters remain identical and the device maintains surface mount compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TL074CDR serves as a direct electrical substitute for the TL074CDBR. Both devices share identical electrical specifications, including amplifier type, circuit count, slew rate, gain-bandwidth product, input bias current, input offset voltage, supply current, and operating temperature range. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

The primary distinction between these parts is the package type and product status. The TL074CDBR uses a 14-SSOP package with 5.30mm width, while the TL074CDR uses a 14-SOIC package with 3.90mm width. The TL074CDR is classified as Active product status with significantly higher inventory availability (113,500 pieces) compared to the TL074CDBR Last Time Buy status (2,139 pieces).

Selection of the TL074CDR is appropriate for applications where PCB layout accommodates the 14-SOIC package footprint. The substitute part maintains full electrical compatibility and regulatory compliance with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the TL074CDR replace the TL074CDBR in existing designs?

A: The TL074CDR provides electrical equivalence to the TL074CDBR. Substitution requires verification that the PCB layout accommodates the 14-SOIC package footprint (0.154" width, 3.90mm) instead of the 14-SSOP package footprint (0.209" width, 5.30mm). Pin configuration and electrical performance are identical.

Q: What is the difference between the 14-SSOP and 14-SOIC packages?

A: The 14-SSOP package has a body width of 5.30mm, while the 14-SOIC package has a body width of 3.90mm. Both are surface mount packages with 14 pins. The SOIC package is narrower and may require PCB layout modifications if the original design was optimized for SSOP dimensions.

Q: Are there any electrical performance differences between TL074CDBR and TL074CDR?

A: No. Both devices share identical electrical specifications across all measured parameters including slew rate, gain-bandwidth product, input bias current, input offset voltage, supply current, and operating temperature range.

Q: Why is the TL074CDBR classified as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this part number. The TL074CDR, which shares the same electrical specifications, is available as an Active product with ongoing manufacturing support.

Q: What are the packaging format differences?

A: The TL074CDBR is supplied in Tape & Reel (TR) format, while the TL074CDR is supplied in Cut Tape (CT) and Digi-Reel® format. These differences affect component handling and automated assembly processes but do not impact electrical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the TL074CDBR and TL074CDR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.
