Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following criteria:

Primary Compatibility Requirements:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Number of Circuits: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Electrical Performance Boundaries: Substitute parts must operate within the voltage supply span of 4V to 44V minimum and maximum. Parts with narrower supply ranges may be acceptable if the application operates within their specified limits. Slew rate, gain bandwidth product, input bias current, and output current are secondary selection criteria based on application requirements.

Substitution Logic:

• Direct Substitutes (Same Amplifier Type): TLE2142AMDR and OP292GSZ variants maintain general-purpose amplifier classification and are interchangeable at the functional level.
• Functional Alternatives (Different Amplifier Type): AD8512BRZ series (J-FET amplifiers) and ADA4075-2ARZ-R7 (iPolar general-purpose) provide equivalent dual-circuit configurations with different input characteristics and supply requirements.
• Extended Alternatives (Audio Amplifiers): OP275GSZ-REEL7 operates as a 2-circuit audio amplifier with different performance specifications and narrower operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Recommended): TLE2142AMDR is the primary substitute for TLE2142AMD. Both parts are manufactured by Texas Instruments with identical electrical specifications, operating temperature range (-55°C to 125°C), and supply voltage span (4V to 44V). The only difference is packaging format: TLE2142AMDR is supplied in Tape & Reel format versus Tube for the original part. TLE2142AMDR maintains Active product status with significantly higher inventory availability (888,600 pcs), ensuring long-term supply continuity. Both parts are ROHS3 Compliant with MSL 1 rating.

Tier 2 - Functional Equivalents (General Purpose Applications): OP292GSZ and OP292GSZ-REEL are general-purpose amplifiers with identical 8-SOIC packaging and Active status. These parts operate within the 4V minimum supply requirement but are limited to 33V maximum supply, making them suitable only for applications not requiring the full 44V upper limit of the TLE2142AMD. Both maintain -40°C to 125°C operating range and ROHS3 compliance. OP292GSZ variants feature lower power consumption (1mA supply current) but reduced slew rate (4V/µs) and gain bandwidth product (4 MHz).

Tier 3 - Alternative Amplifier Types (Specialized Applications): AD8512BRZ series (J-FET amplifiers) provide superior input bias current performance (25 pA versus 700 nA) and higher gain bandwidth product (8 MHz), but operate with restricted supply voltage span (10V to 30V minimum/maximum). These parts are suitable only for applications operating within this narrower range. AD8512BRZ-REEL7 offers the highest inventory availability (29,655 pcs) among AD8512 variants.

ADA4075-2ARZ-R7 (iPolar general-purpose) operates with 9V to 36V supply span and features lower input bias current (30 nA) and supply current (1.8mA) compared to TLE2142AMD, but with reduced slew rate (12V/µs). This part is suitable for low-power applications within its specified voltage range.

Tier 4 - Audio Applications Only: OP275GSZ-REEL7 is classified as an audio amplifier with narrower operating temperature range (-40°C to 85°C), making it unsuitable for the full industrial temperature range of TLE2142AMD (-55°C to 125°C). This part is recommended only for audio-specific applications operating within -40°C to 85°C.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes. All parts carry EAR99 ECCN classification and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q1: Can TLE2142AMDR directly replace TLE2142AMD in existing designs?

A: Yes. TLE2142AMDR is electrically and functionally identical to TLE2142AMD with matching specifications across all electrical parameters, operating temperature range, and supply voltage span. The only difference is packaging format (Tape & Reel versus Tube). Both parts are 8-SOIC surface-mount devices with identical pinout and footprint. TLE2142AMDR is recommended as the primary replacement due to Active product status and higher inventory availability.

Q2: What are the key limitations when substituting OP292GSZ for TLE2142AMD?

A: OP292GSZ operates with a maximum supply voltage of 33V, compared to 44V for TLE2142AMD. Applications requiring supply voltages between 33V and 44V cannot use OP292GSZ. Additionally, OP292GSZ has significantly lower slew rate (4V/µs versus 45V/µs) and gain bandwidth product (4 MHz versus 5.9 MHz), making it unsuitable for high-speed signal processing applications. OP292GSZ is suitable only for low-speed, low-power general-purpose applications within its 4.5V to 33V supply range.

Q3: Are AD8512BRZ variants suitable replacements for general-purpose applications?

A: AD8512BRZ series are J-FET amplifiers with different input characteristics than the general-purpose TLE2142AMD. While both are dual-circuit 8-SOIC devices, AD8512BRZ operates with restricted supply voltage span (10V to 30V) and narrower operating temperature range (-40°C to 125°C versus -55°C to 125°C). AD8512BRZ is suitable only for applications operating within 10V to 30V supply range. The primary advantage is extremely low input bias current (25 pA), beneficial for high-impedance input circuits.

Q4: Can OP275GSZ-REEL7 replace TLE2142AMD in industrial temperature applications?

A: No. OP275GSZ-REEL7 is rated for -40°C to 85°C operating temperature, which does not cover the full industrial range of TLE2142AMD (-55°C to 125°C). This part is unsuitable for applications requiring operation below -40°C or above 85°C. OP275GSZ-REEL7 is classified as an audio amplifier and is recommended only for audio-specific applications within its specified temperature range.

Q5: What packaging options are available for TLE2142 substitutes?

A: TLE2142AMDR is available in Tape & Reel (TR) format with 888,600 pcs inventory. OP292GSZ is available in Tube packaging (1,627 pcs), while OP292GSZ-REEL is available in Cut Tape & Digi-Reel format (9,238 pcs). AD8512BRZ is available in Tube (1,558 pcs), AD8512BRZ-REEL in Tape & Reel (664 pcs), and AD8512BRZ-REEL7 in Cut Tape & Digi-Reel (29,655 pcs). All parts maintain identical 8-SOIC (0.154", 3.90mm Width) package dimensions and surface-mount compatibility.

Q6: Which substitute offers the best supply current efficiency?

A: OP292GSZ and OP292GSZ-REEL offer the lowest supply current at 1mA (x2 channels), compared to 6.9mA for TLE2142AMD. ADA4075-2ARZ-R7 provides intermediate efficiency at 1.8mA supply current. However, lower supply current must be evaluated against reduced slew rate and gain bandwidth product. For applications prioritizing power efficiency over speed, OP292GSZ variants are recommended within their 4.5V to 33V supply range.

Q7: What is the significance of the Last Time Buy status for TLE2142AMD?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of TLE2142AMD. Existing inventory (6,803 pcs) represents the final available stock. Once depleted, this part number will no longer be available. Immediate substitution planning is necessary for long-term design continuity. TLE2142AMDR (Active status, 888,600 pcs available) is the recommended replacement to ensure uninterrupted supply.

Q8: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TLE2142AMDR, AD8512BRZ series, ADA4075-2ARZ-R7, OP275GSZ-REEL7, OP292GSZ variants) are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts carry EAR99 ECCN classification and REACH Unaffected status, meeting standard regulatory requirements for industrial and commercial applications.
