TLV272CDG4 Equivalent & Substitute Parts

Part Overview

The TLV272CDG4 is a general-purpose operational amplifier featuring dual circuits in a rail-to-rail output configuration, manufactured by Texas Instruments in an 8-SOIC surface mount package. This device is classified as obsolete, which necessitates identification of active equivalent alternatives to ensure continued design support and procurement availability. The TLV272CDG4 maintains full electrical and mechanical compatibility with its active counterpart through identical performance specifications and package geometry.

Substitute Part Grouping Explanation

Substitution of the TLV272CDG4 is determined by strict equivalence across all electrical performance parameters and mechanical compatibility criteria. The substitute part must satisfy the following conditions:

Electrical Equivalence Requirements:

• Dual-circuit general-purpose operational amplifier configuration
• Rail-to-rail output type
• Identical slew rate of 2.6 V/µs
• Identical gain bandwidth product of 3 MHz
• Matching input bias current of 1 pA
• Matching input offset voltage of 500 µV
• Matching supply current of 550 µA per channel
• Matching output current per channel of 8 mA
• Supply voltage range spanning 2.7 V to 16 V
• Operating temperature range of 0°C to 70°C

Mechanical Compatibility Requirements:

• Surface mount technology
• 8-SOIC package with 0.154" (3.90mm) width specification

Compliance Requirements:

• ROHS3 compliance
• Moisture sensitivity level 1 (unlimited)

The TLV272CD meets all substitution criteria and is designated as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TLV272CD is the direct equivalent substitute for the obsolete TLV272CDG4. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications across all performance parameters. The primary distinction is product status: the TLV272CDG4 is classified as obsolete, while the TLV272CD is active and currently in production.

Selection of the TLV272CD is supported by the following factors:

Product Status: The TLV272CD maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance Certification: Both parts carry identical regulatory certifications including ROHS3 compliance, REACH unaffected status, and EAR99 export classification.

Electrical Performance: Complete parameter equivalence across slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range ensures direct functional substitution without circuit redesign.

Mechanical Compatibility: Identical 8-SOIC surface mount package geometry and moisture sensitivity level (MSL 1) permit direct board-level substitution.

Packaging Availability: The TLV272CD is supplied in tube packaging, which differs from the TLV272CDG4 packaging specification but does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TLV272CD directly replace the TLV272CDG4 in existing designs?

A: Yes. The TLV272CD is electrically and mechanically equivalent to the TLV272CDG4. All performance parameters, supply voltage ranges, operating temperature specifications, and package geometry are identical. Direct substitution is supported without circuit modification.

Q: What is the primary reason for substitution?

A: The TLV272CDG4 is classified as obsolete. The TLV272CD is the active equivalent manufactured by Texas Instruments and is recommended for new designs and ongoing production requirements.

Q: Are there packaging differences between the two parts?

A: The TLV272CDG4 and TLV272CD are supplied in different packaging formats (the substitute uses tube packaging). However, both parts are housed in identical 8-SOIC surface mount packages with 0.154" (3.90mm) width. This difference affects procurement and handling but not board-level compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the TLV272CDG4 and TLV272CD carry ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level is identical at MSL 1 (unlimited).

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in dual-circuit configuration, rail-to-rail output type, 2.6 V/µs slew rate, 3 MHz gain bandwidth product, 1 pA input bias current, 500 µV input offset voltage, 550 µA supply current per channel, 8 mA output current per channel, and 2.7 V to 16 V supply voltage range.

Q: Is the TLV272CD the only available substitute?

A: Based on the provided data, the TLV272CD is the manufacturer-recommended equivalent. It is the only substitute listed that meets all electrical and mechanical equivalence criteria.

Q: Can the TLV272CD be used in applications requiring the full operating temperature range?

A: Yes. The TLV272CD maintains the same operating temperature range as the TLV272CDG4 (0°C to 70°C), ensuring compatibility across all specified thermal conditions.
