Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2711-1-M-A is determined by the following critical parameters that must be maintained or exceeded:

Isolation Voltage: The substitute must provide 3750Vrms isolation rating to maintain electrical safety and regulatory compliance in the application circuit.

Package Configuration: The substitute must use 4-SOP surface mount packaging with gull wing leads to ensure mechanical and electrical compatibility with existing PCB layouts.

Output Characteristics: The substitute must support transistor output configuration with compatible voltage and current ratings for the load circuit.

Channel Count: Single-channel configuration is required to match the original design topology.

Environmental Rating: Operating temperature range and moisture sensitivity level must be compatible with application requirements.

Compliance Standards: RoHS3 compliance is mandatory for regulatory adherence.

The LTV-357T from Lite-On Inc. meets all critical substitution criteria while offering enhanced performance characteristics in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LTV-357T

The LTV-357T is the direct functional equivalent for PS2711-1-M-A replacement. Both components share identical isolation voltage rating (3750Vrms), channel configuration (1 channel), output type (transistor), and package format (4-SOP surface mount). Both maintain ROHS3 compliance and unlimited moisture sensitivity rating.

The LTV-357T offers distinct advantages in active product status, with current manufacturing and widespread availability through distribution channels. The component is not discontinued and maintains consistent supply.

Performance characteristics of the LTV-357T meet or exceed the PS2711-1-M-A specification in multiple parameters: output current capacity (50mA vs. 40mA), Vce saturation (200mV vs. 300mV), and operating temperature range extension (-55°C to 110°C vs. -55°C to 100°C).

The maximum output voltage rating of the LTV-357T is 35V compared to 40V for the PS2711-1-M-A. Circuit designs operating at voltages between 35V and 40V require evaluation to confirm compatibility with the LTV-357T specification.

Both components are classified under ECCN EAR99 and share identical HTSUS coding (8541.49.8000), indicating equivalent export control and tariff classification.

Frequently Asked Questions (FAQ)

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

A: The LTV-357T is mechanically and electrically compatible for direct PCB substitution. Both components use identical 4-SOP surface mount packaging with gull wing leads. Electrical compatibility is confirmed for applications where the output voltage requirement does not exceed 35V. Designs operating at 35V to 40V output voltage require circuit evaluation.

Q: What is the primary reason for substituting the PS2711-1-M-A?

A: The PS2711-1-M-A is discontinued at DiGi Electronics. The LTV-357T provides an active, currently manufactured alternative with equivalent isolation voltage, channel count, output type, and package configuration.

Q: Are there differences in current transfer ratio specifications between these components?

A: Yes. The PS2711-1-M-A specifies 100% to 200% current transfer ratio at 1mA input current. The LTV-357T specifies 50% to 600% current transfer ratio at 5mA input current. These specifications are measured at different input current levels and cannot be directly compared. Circuit designs must evaluate actual operating conditions against each component's transfer ratio curve.

Q: Does the LTV-357T support the same operating temperature range?

A: The LTV-357T extends the upper operating temperature limit to 110°C compared to 100°C for the PS2711-1-M-A. Both components support the lower limit of -55°C. Applications requiring operation above 100°C benefit from the LTV-357T specification.

Q: What is the significance of the 35V versus 40V maximum output voltage rating?

A: The LTV-357T maximum output voltage is rated at 35V, while the PS2711-1-M-A is rated at 40V. Applications with output voltage requirements between 35V and 40V must confirm compatibility with the LTV-357T specification before substitution.

Q: Are both components RoHS compliant?

A: Yes. Both the PS2711-1-M-A and LTV-357T are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What packaging options are available for the LTV-357T?

A: The LTV-357T is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements.

Q: Is the LTV-357T affected by REACH regulations?

A: The LTV-357T is classified as REACH Unaffected, indicating no substances of very high concern (SVHC) subject to REACH authorization requirements. The PS2711-1-M-A is classified as REACH Affected.
