Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC2654IPG4 is determined by strict adherence to the following criteria:

Package Compatibility: All substitute parts must use the 8-DIP (0.300", 7.62mm) through-hole package to ensure direct PCB footprint compatibility without layout modifications.

Electrical Performance Envelope: Substitute parts must operate within the defined supply voltage range (4.6 V to 16 V minimum and maximum) and maintain the operating temperature range of -40°C to 85°C.

Single-Circuit Configuration: Only single-circuit amplifier devices qualify as substitutes, matching the 1-circuit requirement of the TLC2654IPG4.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements equivalent to the original part.

The identified substitute parts meet these criteria while offering variations in amplifier type classification and performance characteristics within acceptable operational boundaries.

Parameter Comparison

Engineering Selection Recommendations

TLC2654IP (Texas Instruments): This part represents the direct equivalent to the TLC2654IPG4, sharing identical electrical specifications and the same LinCMOS™ series classification. The primary distinction is packaging format (tube versus tray) and product status (Last Time Buy versus discontinued). This part is suitable for applications requiring exact performance matching and maintains full compatibility with existing designs. Current inventory availability is higher than the original part number.

LTC1052CN8#PBF (Analog Devices Inc.): This substitute offers enhanced performance characteristics in specific parameters while maintaining compatibility within the defined operational envelope. The zero-drift amplifier architecture provides superior input offset voltage (0.5 µV versus 5 µV) and input bias current (1 pA versus 50 pA), beneficial for precision measurement applications. The part maintains the required 8-DIP package, supply voltage range, and temperature operating range. Product status is active with established supply chain availability. The gain bandwidth product is lower (1.2 MHz versus 1.9 MHz), which may affect applications requiring higher frequency response.

Both substitute parts satisfy regulatory compliance requirements (ROHS3, REACH unaffected) and maintain the through-hole mounting configuration necessary for direct PCB integration.

Frequently Asked Questions (FAQ)

Q: Can TLC2654IP be used as a direct replacement for TLC2654IPG4?

A: Yes. Both parts share identical electrical specifications, amplifier type classification, and 8-DIP package configuration. The primary difference is packaging format and product lifecycle status. No circuit modifications are required.

Q: What are the key differences between TLC2654IP and LTC1052CN8#PBF?

A: The LTC1052CN8#PBF is a zero-drift amplifier offering superior input offset voltage and input bias current performance. However, it has a lower gain bandwidth product (1.2 MHz versus 1.9 MHz). Both maintain the 8-DIP package and compatible supply voltage ranges. Selection depends on whether precision offset characteristics or higher frequency response is prioritized in the application.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pinout configuration, enabling direct PCB footprint compatibility without layout modifications.

Q: What is the minimum supply voltage requirement for each part?

A: TLC2654IPG4 and TLC2654IP require 4.6 V minimum. LTC1052CN8#PBF requires 4.75 V minimum. All support maximum supply voltage of 16 V.

Q: Which substitute part has the best input offset voltage specification?

A: LTC1052CN8#PBF provides 0.5 µV input offset voltage, compared to 5 µV for both TLC2654IPG4 and TLC2654IP. This makes the LTC1052CN8#PBF suitable for precision analog applications requiring minimal offset drift.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements for electronic component procurement.

Q: What is the current availability status of each part?

A: TLC2654IPG4 is discontinued at DiGi Electronics. TLC2654IP is Last Time Buy status. LTC1052CN8#PBF is Active with ongoing production and supply availability.
