Key Parameters

Substitute Part Grouping Explanation

Substitute optoisolators for the PS2711-1-F3-M-A must meet the following criteria based on allowed electrical and mechanical parameters:

Critical Parameters for Substitution:

• Isolation voltage: 3750Vrms (must be met or exceeded)
• Output type: Transistor
• Package type: 4-SMD, Gull Wing (4-SOP)
• Mounting type: Surface Mount
• Input type: DC
• Number of channels: 1

The LTV-357T qualifies as a direct substitute, sharing identical isolation voltage, output configuration, package geometry, and mounting type. Both components comply with ROHS3 standards and operate within the required temperature ranges for typical applications.

Parameter Comparison

Engineering Selection Recommendations

The LTV-357T from Lite-On Inc. is a functionally equivalent substitute for the discontinued PS2711-1-F3-M-A. Both components share identical isolation voltage specifications and package configurations. The LTV-357T offers active product status with established supply availability, making it suitable for new designs and production continuity.

Selection between these components should be based on:

Electrical Performance: The LTV-357T provides higher output current capability (50mA vs. 40mA) and lower saturation voltage (200mV vs. 300mV), resulting in improved switching performance and reduced power dissipation in the output stage.

Operating Temperature: The LTV-357T extends the upper operating temperature limit to 110°C, compared to the PS2711-1-F3-M-A's 100°C, providing additional thermal margin for high-temperature applications.

Supply Status: The LTV-357T remains in active production with commercial availability, whereas the PS2711-1-F3-M-A is discontinued.

Compliance: Both components meet ROHS3 and REACH requirements, ensuring regulatory compliance for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the LTV-357T directly replace the PS2711-1-F3-M-A in existing designs?

A: Yes. The LTV-357T is pin-compatible and shares identical isolation voltage, channel configuration, and package geometry. Both use 4-SOP surface mount packages with gull wing lead configuration. No PCB layout modifications are required.

Q: What are the key differences between these optoisolators?

A: Primary differences include output current rating (LTV-357T: 50mA vs. PS2711-1-F3-M-A: 40mA), maximum output voltage (LTV-357T: 35V vs. PS2711-1-F3-M-A: 40V), saturation voltage (LTV-357T: 200mV vs. PS2711-1-F3-M-A: 300mV), and maximum operating temperature (LTV-357T: 110°C vs. PS2711-1-F3-M-A: 100°C).

Q: Are there packaging differences between these parts?

A: Both components use identical 4-SMD gull wing packages with 4-SOP pinout. The main packaging difference is supply format: the PS2711-1-F3-M-A is supplied in Tape & Reel (TR), while the LTV-357T is available in Cut Tape (CT) and Digi-Reel® formats.

Q: Do both components meet the same compliance standards?

A: Yes. Both the PS2711-1-F3-M-A and LTV-357T are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8541.49.8000.
