Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC27M4CPWR is determined by strict adherence to the following electrical and mechanical compatibility criteria:

Package Compatibility: Both the main part and substitute must use the 14-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width) to ensure direct PCB footprint compatibility without layout modifications.

Circuit Configuration: The substitute must contain four independent amplifier circuits to maintain functional equivalence in multi-channel applications.

Supply Voltage Range: The substitute must operate within the specified voltage supply span of 3V minimum to 16V maximum to ensure compatibility with existing power distribution designs.

Compliance Standards: Both parts must maintain ROHS3 compliance and MSL Level 1 rating to satisfy manufacturing and environmental requirements.

Mounting Technology: Surface mount technology is required for both parts to maintain assembly process compatibility.

The TS27L4IPT from STMicroelectronics meets all these mandatory substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the TLC27M4CPWR and TS27L4IPT maintain Active product status, ensuring long-term availability and manufacturing support. Both devices are ROHS3 compliant and carry MSL Level 1 rating, satisfying environmental and moisture sensitivity requirements for standard manufacturing environments.

The TS27L4IPT offers an extended operating temperature range (-40°C ~ 125°C) compared to the TLC27M4CPWR (0°C ~ 70°C), providing broader thermal application flexibility. The TS27L4IPT also demonstrates significantly lower supply current consumption (10µA versus 570µA across four channels), making it advantageous for power-constrained applications.

The TLC27M4CPWR exhibits higher slew rate (0.62V/µs versus 0.04V/µs) and gain bandwidth product (525kHz versus 100kHz), characteristics that may be required for higher-frequency signal processing applications.

Both parts share identical input offset voltage (1.1mV), identical supply voltage range (3V to 16V), and identical package specifications, confirming direct mechanical and electrical compatibility within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the TS27L4IPT directly replace the TLC27M4CPWR on an existing PCB without layout modifications?

A: Yes. Both devices use the identical 14-TSSOP package with matching physical dimensions (0.173", 4.40mm Width) and pin configuration, enabling direct footprint compatibility without PCB redesign.

Q: What are the key electrical differences between these two parts?

A: The primary differences are slew rate (TLC27M4CPWR: 0.62V/µs; TS27L4IPT: 0.04V/µs), gain bandwidth product (TLC27M4CPWR: 525kHz; TS27L4IPT: 100kHz), supply current (TLC27M4CPWR: 570µA; TS27L4IPT: 10µA), and operating temperature range (TLC27M4CPWR: 0°C~70°C; TS27L4IPT: -40°C~125°C).

Q: Which part should be selected for low-power applications?
