Substitute Part Grouping Explanation

Substitution of the TLC073CNG4 is determined by strict equivalence across electrical and mechanical parameters. The primary substitute identified is the TLC073IN, which shares the same base product number (TLC073) and maintains identical electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. Both devices utilize the 14-DIP through-hole package format with identical pin configuration and mechanical dimensions.

The substitution logic is based on the following critical parameters:

• Amplifier Type: CMOS (identical)
• Number of Circuits: 2 (identical)
• Slew Rate: 19 V/µs (identical)
• Gain Bandwidth Product: 10 MHz (identical)
• Current - Input Bias: 1.5 pA (identical)
• Voltage - Input Offset: 390 µV (identical)
• Current - Supply: 2.1 mA (x2 Channels) (identical)
• Current - Output / Channel: 57 mA (identical)
• Voltage - Supply Span: 4.5V to 16V (identical)
• Package / Case: 14-DIP (0.300", 7.62mm) (identical)
• Mounting Type: Through Hole (identical)

Parameter Comparison

Engineering Selection Recommendations

The TLC073IN serves as a direct functional equivalent to the TLC073CNG4 with identical electrical performance across all specified parameters. The primary distinction lies in product lifecycle status: the TLC073CNG4 is obsolete with no further production, while the TLC073IN maintains Last Time Buy status, indicating extended procurement availability.

From a compliance perspective, both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system maintenance. The TLC073IN offers an extended operating temperature range (-40°C to 125°C) compared to the TLC073CNG4 (0°C to 70°C), providing greater thermal flexibility for applications requiring operation outside standard industrial temperature bands.

Pin-for-pin compatibility is confirmed through identical 14-DIP package specifications and through-hole mounting configuration. Direct substitution in existing PCB layouts is feasible without design modification.

Frequently Asked Questions (FAQ)

Q: Can the TLC073IN be used as a direct replacement for the TLC073CNG4 in existing designs?

A: Yes. The TLC073IN is electrically and mechanically equivalent to the TLC073CNG4.
