TLC2252QDREP Equivalent & Substitute Parts

Part Overview

The TLC2252QDREP is a general-purpose operational amplifier featuring dual circuits in a rail-to-rail output configuration, packaged in an 8-SOIC surface mount package. Manufactured by Texas Instruments as part of the LinCMOS™ series, this device is designed for low-power analog signal processing applications requiring automotive-grade reliability.

The TLC2252QDREP is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements. Active alternatives with identical electrical and mechanical specifications are available from the same manufacturer.

Substitute Part Grouping Explanation

Substitute parts for the TLC2252QDREP are determined by strict equivalence across all electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameter Equivalence:

• Amplifier type (General Purpose)
• Number of circuits (2)
• Output configuration (Rail-to-Rail)
• Slew rate (0.12 V/µs)
• Gain bandwidth product (210 kHz)
• Input bias current (1 pA)
• Input offset voltage (200 µV)
• Supply current per channel (80 µA)
• Output current per channel (50 mA)
• Supply voltage range (4.4 V to 16 V)
• Operating temperature range (-40°C to 125°C)

Mechanical Parameter Equivalence:

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

Compliance Equivalence:

• RoHS3 compliance
• MSL rating (1 - Unlimited)
• REACH unaffected status
• ECCN classification (EAR99)

All identified substitute parts maintain complete parameter parity with the main part number across electrical, mechanical, and compliance specifications.

Parameter Comparison

Engineering Selection Recommendations

TLC2252AIDR is classified as an active product with current manufacturing status. This part is available in Cut Tape (CT) and Digi-Reel® packaging formats, with 35,400 units in stock. The TLC2252AIDR maintains complete electrical and mechanical equivalence to the obsolete TLC2252QDREP and is suitable for direct substitution in new designs and production runs.

TLC2252IDR is designated as the manufacturer-recommended alternative, also classified as an active product. This part is available in Cut Tape (CT) and Digi-Reel® packaging formats, with 15,702 units in stock. The TLC2252IDR provides identical electrical performance and mechanical compatibility, making it a qualified replacement for the obsolete TLC2252QDREP.

Both substitute parts satisfy automotive-grade requirements through AEC-Q100 qualification (where applicable to the main part), maintain ROHS3 compliance, and carry unlimited moisture sensitivity ratings. Selection between TLC2252AIDR and TLC2252IDR should be based on inventory availability, packaging format requirements, and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can TLC2252AIDR and TLC2252IDR be used interchangeably with TLC2252QDREP?

A: Yes. Both substitute parts maintain complete parameter equivalence across all electrical specifications (slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range), mechanical specifications (8-SOIC package, 0.154" width, 3.90mm), and operating temperature range (-40°C to 125°C). Direct substitution is supported without circuit modification.

Q: What is the primary difference between TLC2252AIDR and TLC2252IDR?

A: Both parts are electrically and mechanically identical. The primary differences are product status classification and inventory levels. TLC2252AIDR has 35,400 units in stock, while TLC2252IDR has 15,702 units in stock. Both are active products available in Cut Tape (CT) and Digi-Reel® packaging.

Q: Is the 8-SOIC package compatible with existing PCB layouts designed for TLC2252QDREP?

A: Yes. All three part numbers use the identical 8-SOIC package with 0.154" width and 3.90mm dimensions. PCB footprints, solder pad layouts, and mounting procedures remain unchanged.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), REACH unaffected status, and EAR99 ECCN classification. Compliance requirements are fully satisfied by both substitute parts.

Q: What supply voltage range is supported by the substitute parts?

A: Both TLC2252AIDR and TLC2252IDR support the identical supply voltage range of 4.4 V minimum to 16 V maximum, matching the TLC2252QDREP specification.

Q: Can these parts be used in automotive applications?

A: The main part TLC2252QDREP carries automotive-grade designation with AEC-Q100 qualification. The substitute parts TLC2252AIDR and TLC2252IDR maintain the same electrical and mechanical specifications required for automotive applications, though specific automotive qualification status should be confirmed with the manufacturer for critical applications.
