Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2141IPG4 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package type: 8-DIP (0.300", 7.62mm) with 8-PDIP supplier device package
• Mounting type: Through Hole
• Number of circuits: 1
• Pin configuration: Standard 8-pin DIP footprint

Electrical Performance Criteria:

• Gain Bandwidth Product: 5.9 MHz (TLE2141IPG4 baseline)
• Slew Rate: 45 V/µs (TLE2141IPG4 baseline)
• Supply voltage range: Minimum 4 V to maximum 44 V
• Input offset voltage: 200 µV
• Output current capability: 50 mA per channel

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status
• ECCN: EAR99 classification

Substitute parts must maintain electrical compatibility within the 8-DIP package form factor. Parts with different amplifier types (J-FET vs. General Purpose) may substitute if electrical parameters remain within acceptable application tolerances and package compatibility is preserved.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLE2141IP

The TLE2141IP from Texas Instruments is the direct equivalent to TLE2141IPG4. Both parts share identical electrical specifications, including 45 V/µs slew rate, 5.9 MHz gain bandwidth product, and 4 V to 44 V supply voltage range. The TLE2141IP is available in higher inventory (5500 pieces) and maintains Last Time Buy status, providing better procurement security than the discontinued TLE2141IPG4. Both parts are ROHS3 compliant and REACH unaffected. The only difference is packaging format (Tube vs. standard packaging), which does not affect electrical performance or PCB integration.

Secondary Substitutes: LT1792 Series (LT1792AIN8#PBF, LT1792ACN8#PBF, LT1792CN8#PBF)

The LT1792 series from Analog Devices Inc. provides functional substitution with comparable gain bandwidth product (5.6 MHz) and identical input offset voltage (200 µV). These J-FET amplifiers maintain the 8-DIP package form factor and are actively produced. The LT1792AIN8#PBF variant supports the extended temperature range (-40°C to 85°C) matching the TLE2141IPG4 operating window. Trade-offs include reduced slew rate (3.4 V/µs vs. 45 V/µs) and narrower maximum supply voltage (40 V vs. 44 V). These parts are suitable for applications where high slew rate is not critical.

Tertiary Substitutes: AD711KNZ, LT1055CN8#PBF, LT1056CN8#PBF

These J-FET amplifiers provide alternative solutions with reduced slew rates (20 V/µs, 12 V/µs, and 14 V/µs respectively) and lower input bias currents. The AD711KNZ offers 4 MHz bandwidth with 25 mA output current, requiring minimum 9 V supply. The LT1055CN8#PBF and LT1056CN8#PBF provide 4.5 MHz and 5.5 MHz bandwidth respectively, with 10 V minimum supply requirement. These options are suitable for low-noise, low-bias-current applications where supply voltage constraints are acceptable.

Compliance Verification

All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting environmental regulatory requirements. ECCN classification remains EAR99 across all alternatives. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special handling requirements.

Frequently Asked Questions (FAQ)

Q1: Can TLE2141IP directly replace TLE2141IPG4 without circuit modification?

A: Yes. The TLE2141IP is electrically identical to TLE2141IPG4, with matching specifications across all critical parameters including slew rate (45 V/µs), gain bandwidth product (5.9 MHz), supply voltage range (4 V to 44 V), and output current (50 mA). Both use the 8-DIP package. The only difference is packaging format (Tube). No circuit modifications are required.

Q2: What are the key differences between TLE2141IPG4 and LT1792 series substitutes?

A: The primary differences are amplifier type (General Purpose vs. J-FET) and slew rate. TLE2141IPG4 provides 45 V/µs slew rate compared to 3.4 V/µs for LT1792 variants. The LT1792 series offers lower input bias current (300 pA vs. 700 nA) and comparable gain bandwidth product (5.6 MHz vs. 5.9 MHz). Maximum supply voltage is 40 V for LT1792 versus 44 V for TLE2141IPG4. Substitution is valid for applications not requiring high slew rate performance.

Q3: Which substitute part supports the full temperature range of TLE2141IPG4?

A: The LT1792AIN8#PBF supports the extended temperature range of -40°C to 85°C, closely matching the TLE2141IPG4 range of -40°C to 105°C. Other LT1792 variants (LT1792ACN8#PBF and LT1792CN8#PBF) are limited to 0°C to 70°C. The TLE2141IP maintains the identical -40°C to 105°C range as the original part.

Q4: Are all substitute parts available in 8-DIP through-hole packaging?

A: Yes. All substitute parts listed are available in 8-DIP (0.300", 7.62mm) through-hole packaging with 8-PDIP supplier device package designation. This ensures direct PCB footprint compatibility without layout modifications.

Q5: What is the impact of reduced slew rate when substituting with LT1792 series?

A: Reduced slew rate (3.4 V/µs vs. 45 V/µs) affects the amplifier's ability to respond to rapid voltage changes. Applications with fast transient signals or high-frequency switching may experience performance degradation. Low-frequency signal conditioning, precision measurement, and audio applications typically tolerate lower slew rates. Circuit simulation or bench testing is necessary to confirm suitability for specific applications.

Q6: Do all substitute parts meet RoHS3 and REACH compliance?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. Moisture sensitivity level is 1 (Unlimited) for all parts, requiring no special storage or handling procedures.

Q7: What is the inventory status of substitute parts?

A: TLE2141IP has 5500 pieces available (Last Time Buy status). LT1792AIN8#PBF has 944 pieces, LT1792ACN8#PBF has 2270 pieces, and LT1792CN8#PBF has 1900 pieces in active production. AD711KNZ has 1271 pieces, LT1055CN8#PBF has 1500 pieces, and LT1056CN8#PBF has 1320 pieces available. TLE2141IP provides the highest inventory and best long-term availability.

Q8: Can J-FET amplifiers (AD711, LT1055, LT1056, LT1792) substitute for the general-purpose TLE2141IPG4?

A: J-FET amplifiers can substitute if application requirements permit lower slew rates and different input bias characteristics. J-FET types offer significantly lower input bias current (15 pA to 300 pA vs. 700 nA), beneficial for high-impedance signal sources. However, reduced slew rate and narrower supply voltage ranges must be verified against circuit requirements. Direct substitution is not recommended without application-specific analysis.
