Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2565L-2-V is determined by the following critical parameters that must align with the original design requirements:

Primary Matching Criteria:

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

Secondary Compatibility Factors:

• Voltage - Output (Max): Must support application requirements
• Current - Output / Channel: Must meet or exceed circuit demands
• Operating Temperature Range: Must encompass application environment
• Vce Saturation: Affects switching performance
• Rise / Fall Time: Impacts signal integrity

The LTV-824HS-TA1 from Lite-On Inc. satisfies the primary matching criteria 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.

Engineering Selection Recommendations

LTV-824HS-TA1 as Primary Substitute:

The LTV-824HS-TA1 is the recommended substitute for the obsolete PS2565L-2-V. Both components share identical isolation voltage (5000Vrms), channel configuration (2-channel), output topology (transistor), and physical packaging (8-SMD gull wing surface mount).

The LTV-824HS-TA1 carries active product status, ensuring long-term availability and supply chain continuity. This part is ROHS3 compliant, meeting current environmental and regulatory requirements, whereas the PS2565L-2-V is RoHS non-compliant.

Design Consideration - Output Voltage Rating:

The PS2565L-2-V specifies a maximum output voltage of 80V, while the LTV-824HS-TA1 is rated for 35V maximum output voltage. Applications requiring output voltages exceeding 35V require circuit redesign or alternative component selection.

Design Consideration - Operating Temperature Range:

The PS2565L-2-V operates across -55°C to 100°C, while the LTV-824HS-TA1 operates across -30°C to 100°C. Applications requiring operation below -30°C require alternative component selection.

Design Consideration - Output Current:

The LTV-824HS-TA1 provides 80mA per channel output current, exceeding the PS2565L-2-V specification of 50mA per channel. This represents improved current capability for the substitute part.

Frequently Asked Questions (FAQ)

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

A: Direct replacement is possible when the application output voltage requirement does not exceed 35V and the operating temperature range remains within -30°C to 100°C. The LTV-824HS-TA1 provides superior output current capability (80mA vs. 50mA per channel) and improved Vce saturation performance (200mV vs. 300mV). Applications exceeding these parameters require alternative component selection or circuit modification.

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

A: The primary electrical differences are maximum output voltage (PS2565L-2-V: 80V; LTV-824HS-TA1: 35V), operating temperature range (PS2565L-2-V: -55°C to 100°C; LTV-824HS-TA1: -30°C to 100°C), and Vce saturation (PS2565L-2-V: 300mV; LTV-824HS-TA1: 200mV). Both parts maintain identical 5000Vrms isolation voltage and 2-channel transistor output configuration.

Q: Are the packages physically identical?

A: Yes. Both the PS2565L-2-V and LTV-824HS-TA1 utilize 8-SMD gull wing surface mount packaging, enabling direct PCB footprint compatibility without layout modifications.

Q: What is the significance of the RoHS compliance difference?

A: The PS2565L-2-V is RoHS non-compliant, while the LTV-824HS-TA1 is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the LTV-824HS-TA1 satisfies these requirements. The PS2565L-2-V cannot be used in such applications.

Q: How do the current transfer ratios compare?

A: The PS2565L-2-V specifies 80% minimum at 5mA and 400% maximum at 100mA. The LTV-824HS-TA1 specifies 20% minimum at 100mA and 80% maximum at 100mA. These specifications reflect different measurement conditions and should be evaluated against specific circuit requirements.

Q: What inventory status should influence component selection?

A: The PS2565L-2-V is obsolete with 1064 pieces in current stock. The LTV-824HS-TA1 is active product with 900 pieces in current stock. For new designs or long-term production requirements, the LTV-824HS-TA1 is the appropriate selection due to active product status and ongoing manufacturer support.
