Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC27M7CPS is determined by the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type: CMOS
• Number of Circuits: 2
• Mounting Type: Surface Mount
• Package Category: 8-SOIC (pin-compatible)
• Supply Voltage Range: Minimum 3V, Maximum 16V
• Output Current per Channel: 30 mA minimum

Secondary Compatibility Parameters:

• Slew Rate: 0.62 V/µs or higher
• Gain Bandwidth Product: 635 kHz or higher
• Input Bias Current: 0.7 pA or lower
• Input Offset Voltage: 190 µV or lower
• Supply Current: 285 µA per channel or lower

The TLC27M7CPS has two identified substitutes: TLC27M7CDR (manufacturer recommended) and LM432MA/NOPB. The TLC27M7CDR maintains identical electrical specifications and differs only in packaging format (Cut Tape versus Tube). The LM432MA/NOPB represents a functional alternative with different electrical characteristics and product status considerations.

Parameter Comparison

Engineering Selection Recommendations

TLC27M7CDR (Manufacturer Recommended Substitute)

The TLC27M7CDR is the primary substitute for the TLC27M7CPS. Both parts share identical electrical specifications, including slew rate, gain bandwidth product, input bias current, input offset voltage, and supply current characteristics. The TLC27M7CDR is currently in Active product status, ensuring long-term availability and supply chain stability. The only functional difference is packaging format: TLC27M7CPS is supplied in Tube packaging, while TLC27M7CDR is supplied in Cut Tape format. Both maintain ROHS3 compliance and MSL Level 1 rating. The TLC27M7CDR is suitable for direct replacement in new designs and production runs.

LM432MA/NOPB (Functional Alternative)

The LM432MA/NOPB is a functional alternative with different electrical characteristics and should be selected only when design specifications permit deviation from the original TLC27M7CPS parameters. Key differences include: higher gain bandwidth product (1000 kHz versus 635 kHz), higher input bias current (3 nA versus 0.7 pA), higher input offset voltage (600 µV versus 190 µV), and lower supply current (150 µA versus 285 µA per channel). The LM432MA/NOPB operates across a wider temperature range (-40°C to 85°C versus 0°C to 70°C) and supports a lower minimum supply voltage (2.5V versus 3V). However, the LM432MA/NOPB is classified as Obsolete, limiting its suitability for new production. This part is ROHS3 compliant and maintains MSL Level 1 rating.

Frequently Asked Questions (FAQ)

Q: Can TLC27M7CDR be used as a direct replacement for TLC27M7CPS?

A: Yes. The TLC27M7CDR is electrically identical to the TLC27M7CPS. Both parts are CMOS dual-channel amplifiers with identical slew rate (0.62 V/µs), gain bandwidth product (635 kHz), input bias current (0.7 pA), input offset voltage (190 µV), and supply current specifications (285 µA per channel). The difference is packaging format only: Tube versus Cut Tape. Pin configuration and electrical performance are equivalent.

Q: What is the difference between the 8-SO and 8-SOIC packages?

A: The TLC27M7CPS uses an 8-SO package with 5.30mm width, while the TLC27M7CDR uses an 8-SOIC package with 3.90mm width. Both are surface mount packages with 8 pins and identical pin assignments. The primary difference is physical footprint size. PCB layout and design files may require adjustment to accommodate the different package dimensions.

Q: Is LM432MA/NOPB suitable for replacing TLC27M7CPS in existing designs?

A: LM432MA/NOPB is a functional alternative only if design specifications permit higher input offset voltage (600 µV versus 190 µV) and higher input bias current (3 nA versus 0.7 pA). The LM432MA/NOPB offers higher gain bandwidth product (1000 kHz) and lower supply current consumption. However, LM432MA/NOPB is classified as Obsolete, making it unsuitable for new production. For existing designs requiring a substitute, TLC27M7CDR is the recommended choice.

Q: Are all three parts ROHS3 compliant?

A: Yes. TLC27M7CPS, TLC27M7CDR, and LM432MA/NOPB are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All three parts are suitable for applications requiring environmental compliance certification.

Q: What is the product status significance?

A: TLC27M7CPS is Last Time Buy, indicating production has ended. TLC27M7CDR is Active, ensuring continued availability and supply chain support. LM432MA/NOPB is Obsolete, meaning it is no longer manufactured and inventory is limited. For new designs and long-term production, TLC27M7CDR is the appropriate selection.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: TLC27M7CPS and TLC27M7CDR can be used interchangeably electrically but require different PCB footprints due to package size differences (5.30mm versus 3.90mm width). LM432MA/NOPB shares the same 3.90mm footprint as TLC27M7CDR but has different electrical characteristics that may affect circuit performance.
