Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2565L-2-V-A is determined by the following critical parameters that must be maintained or exceeded:

Mandatory Matching Parameters:

• Number of Channels: 2
• Voltage - Isolation: 5000Vrms minimum
• Output Type: Transistor
• Mounting Type: Surface Mount
• Package / Case: 8-SMD, Gull Wing

Performance Parameters for Compatibility:

• Voltage - Output (Max): Must support 80V or higher
• Current - Output / Channel: Must support 50mA or higher
• Input Type: AC, DC compatibility required
• Operating Temperature Range: Must encompass or exceed -55°C ~ 100°C

The LTV-824HS-TA1 manufactured by Lite-On Inc. meets the mandatory matching parameters with identical channel count, isolation voltage, output type, and package configuration. This part is classified as active product status, ensuring ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The PS2565L-2-V-A is obsolete, making the LTV-824HS-TA1 the primary substitute option. The LTV-824HS-TA1 maintains active product status with Lite-On Inc., ensuring long-term availability and supply chain continuity.

Compliance and Certification: Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, indicating equivalent regulatory treatment. Both components feature MSL 1 (Unlimited) moisture sensitivity rating, requiring no special handling during storage or assembly.

Parameter Compatibility Assessment: The LTV-824HS-TA1 provides higher output current capability (80mA vs. 50mA per channel) and improved saturation characteristics (200mV vs. 300mV Vce max). However, the maximum output voltage is reduced to 35V compared to the PS2565L-2-V-A's 80V rating. Applications requiring output voltages exceeding 35V cannot use the LTV-824HS-TA1 as a direct substitute.

The operating temperature range of the LTV-824HS-TA1 (-30°C ~ 100°C) is narrower than the PS2565L-2-V-A (-55°C ~ 100°C). Applications requiring operation below -30°C require design verification or alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the LTV-824HS-TA1 directly replace the PS2565L-2-V-A in all applications?

A: The LTV-824HS-TA1 is compatible with applications where the output voltage requirement does not exceed 35V and the operating temperature range remains within -30°C to 100°C. Applications requiring higher output voltages or lower temperature operation require circuit redesign or alternative component selection.

Q: What are the key differences in electrical performance between these components?

A: The LTV-824HS-TA1 provides superior output current capability (80mA vs. 50mA per channel) and lower saturation voltage (200mV vs. 300mV). The PS2565L-2-V-A supports higher maximum output voltage (80V vs. 35V) and wider operating temperature range (-55°C to 100°C vs. -30°C to 100°C).

Q: Are the package configurations identical?

A: Both components use 8-SMD gull wing surface mount packaging, ensuring mechanical and electrical compatibility on PCB layouts designed for either part.

Q: What is the significance of the current transfer ratio differences?

A: The PS2565L-2-V-A specifies 80% minimum CTR at 5mA input current, while the LTV-824HS-TA1 specifies 20% minimum CTR at 100mA input current. These specifications reflect different input current operating points and must be evaluated against specific circuit requirements.

Q: Are there regulatory or compliance concerns when substituting these components?

A: Both components share identical ECCN and HTSUS classifications. No additional regulatory review is required from a trade classification perspective. However, circuit-level validation is necessary to confirm electrical performance meets application requirements.
