Substitute Part Grouping Explanation

Substitution of the TLE2021CP is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

Amplifier type (General Purpose)
Number of circuits (1)
Slew rate (0.65 V/µs minimum)
Gain bandwidth product (2 MHz minimum)
Input bias current (25 nA maximum)
Input offset voltage (150 µV maximum)
Supply current (240 µA maximum)
Output current per channel (20 mA minimum)
Supply voltage range (4V to 40V minimum span)
Operating temperature range (0°C to 70°C minimum coverage)

Mechanical Compatibility Criteria:

Package type (8-DIP through-hole or equivalent surface-mount alternative)
Pin count (8 pins)
Physical footprint compatibility

Compliance Criteria:

RoHS3 compliance
REACH unaffected status
ECCN classification (EAR99)

Substitute parts must maintain electrical performance within the specified parameters while offering improved availability or alternative packaging options. Parts that exceed the specified performance envelope remain functionally compatible but may represent over-specification for the application.

Engineering Selection Recommendations

TLE2021CDR (Texas Instruments, Active Status)

The TLE2021CDR is the manufacturer-recommended substitute for the TLE2021CP. Both parts share identical electrical specifications and are members of the same TLE2021 base product family. The primary difference is packaging: TLE2021CDR uses 8-SOIC surface-mount technology versus the through-hole 8-DIP configuration of the TLE2021CP.

Selection of TLE2021CDR is appropriate for new designs or redesigns that accommodate surface-mount assembly. The part maintains full electrical compatibility, carries Active product status ensuring long-term availability, and provides significantly higher inventory levels (21,568 pieces versus 1,404 pieces). Both parts are ROHS3 compliant and REACH unaffected.

OP90GPZ (Analog Devices Inc., Active Status)

The OP90GPZ is an alternative general-purpose operational amplifier that maintains the same 8-DIP through-hole package as the TLE2021CP, eliminating the need for PCB redesign. The OP90GPZ meets or exceeds the electrical performance requirements of the TLE2021CP across all critical parameters:

Input bias current: 4 nA (versus 25 nA required)
Input offset voltage: 125 µV (versus 150 µV required)
Supply current: 14 µA (versus 240 µA required)
Extended operating temperature range: -40°C to 85°C (versus 0°C to 70°C)

The OP90GPZ exhibits lower slew rate (0.012 V/µs versus 0.65 V/µs) and reduced output current capability (5 mA versus 20 mA). These parameters represent performance reduction and require verification against application-specific requirements. The OP90GPZ carries Active product status and is ROHS3 compliant.

Selection Criteria Summary:

For surface-mount PCB designs: TLE2021CDR
For through-hole designs requiring package compatibility: OP90GPZ
For existing through-hole designs with performance margin: TLE2021CDR with PCB redesign to surface-mount

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original TLE2021CP.

Frequently Asked Questions (FAQ)

Q: Can TLE2021CDR be used as a direct replacement for TLE2021CP in existing through-hole PCB designs?

A: No. TLE2021CDR uses 8-SOIC surface-mount packaging while TLE2021CP uses 8-DIP through-hole packaging. Direct PCB substitution is not possible without redesign. However, TLE2021CDR is electrically identical and suitable for new or redesigned boards using surface-mount assembly.

Q: What are the key electrical differences between TLE2021CP and OP90GPZ?

A: Both parts maintain the same gain bandwidth product (2 MHz) and operate as general-purpose amplifiers. OP90GPZ provides superior performance in input bias current (4 nA versus 25 nA), input offset voltage (125 µV versus 150 µV), and supply current (14 µA versus 240 µA). However, OP90GPZ has lower slew rate (0.012 V/µs versus 0.65 V/µs) and reduced output current capability (5 mA versus 20 mA). Applications requiring high-speed transient response or high output current may not be suitable for OP90GPZ substitution.

Q: Is OP90GPZ compatible with the 8-DIP through-hole footprint of TLE2021CP?

A: Yes. Both TLE2021CP and OP90GPZ use 8-DIP (0.300", 7.62mm) through-hole packaging. Pin-for-pin substitution is mechanically possible without PCB modification.

Q: Why does TLE2021CP have Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has discontinued the TLE2021CP product line. Existing inventory will be depleted without replenishment. TLE2021CDR (Active status) is the manufacturer's recommended path forward for continued supply.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLE2021CP, TLE2021CDR, and OP90GPZ are all ROHS3 compliant and REACH unaffected, ensuring regulatory compliance across all substitute options.

Q: What is the inventory availability difference between substitute parts?

A: TLE2021CDR has the highest inventory at 21,568 pieces. OP90GPZ has 1,363 pieces. TLE2021CP has 1,404 pieces remaining. For long-term supply security, TLE2021CDR is the preferred choice due to Active product status and significantly higher stock levels.

Q: Can OP90GPZ be used in applications requiring 20 mA output current?

A: No. OP90GPZ is rated for 5 mA output current per channel, which is insufficient for applications requiring 20 mA output current. Verify application output current requirements before selecting OP90GPZ as a substitute.

Q: What is the operating temperature range difference between TLE2021CP and OP90GPZ?

A: TLE2021CP operates from 0°C to 70°C. OP90GPZ operates from -40°C to 85°C, providing extended temperature coverage. Applications operating outside the 0°C to 70°C range require OP90GPZ or equivalent extended-temperature parts.
