PS2505L-2 Equivalent & Substitute Parts

Part Overview

The PS2505L-2 is a 2-channel optoisolator with transistor output manufactured by CEL, designed for 5000Vrms isolation applications. This component features surface mount packaging in an 8-SMD gull wing configuration and supports both AC and DC input types. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain compatibility across isolation voltage, channel configuration, output type, and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2505L-2 optoisolator is determined by the following critical parameters:

Primary Compatibility Criteria:

• Voltage isolation rating of 5000Vrms
• 2-channel configuration
• Transistor output topology
• 8-SMD surface mount package with gull wing leads
• AC and DC input capability

Secondary Compatibility Criteria:

• Current transfer ratio performance at specified test conditions
• Output voltage and current ratings
• Rise and fall time characteristics
• Operating temperature range
• Saturation voltage specifications

The LTV-824HS-TA1 from Lite-On Inc. satisfies all primary compatibility criteria and qualifies as a direct substitute. This part maintains the same isolation voltage, channel count, output type, and package configuration while offering active product status and RoHS3 compliance.

Engineering Selection Recommendations

Primary Substitute: LTV-824HS-TA1

The LTV-824HS-TA1 is the recommended substitute for the obsolete PS2505L-2. This selection is based on the following engineering factors:

1. Product Status: The LTV-824HS-TA1 maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete PS2505L-2.

2. Regulatory Compliance: The LTV-824HS-TA1 is ROHS3 compliant, meeting current environmental and regulatory requirements. The PS2505L-2 is RoHS non-compliant and REACH affected, presenting compliance risks for new applications.

3. Functional Equivalence: Both parts maintain identical isolation voltage (5000Vrms), channel configuration (2-channel), output topology (transistor), and package specification (8-SMD gull wing).

4. Parameter Differences: The LTV-824HS-TA1 exhibits lower maximum output voltage (35V vs. 80V) and different current transfer ratio characteristics. Applications requiring the full 80V output rating or higher current transfer ratio performance at 5mA input current must evaluate circuit-level compatibility.

5. Temperature Range: The PS2505L-2 supports extended low-temperature operation (-55°C vs. -30°C). Applications requiring operation below -30°C require thermal performance verification.

Frequently Asked Questions (FAQ)

Q: Can the LTV-824HS-TA1 directly replace the PS2505L-2 in existing designs?

A: The LTV-824HS-TA1 maintains compatibility across isolation voltage, channel count, output type, and package configuration. However, circuit-level verification is required for applications dependent on the PS2505L-2's maximum output voltage rating (80V) or current transfer ratio performance at 5mA input current, as the LTV-824HS-TA1 specifies different performance at different test conditions.

Q: What are the key differences between these optoisolators?

A: The primary differences are maximum output voltage (PS2505L-2: 80V; LTV-824HS-TA1: 35V), current transfer ratio test conditions (PS2505L-2: 80-600% @ 5mA; LTV-824HS-TA1: 20-80% @ 100mA), operating temperature range (PS2505L-2: -55°C to 100°C; LTV-824HS-TA1: -30°C to 100°C), and regulatory compliance status (PS2505L-2: RoHS non-compliant; LTV-824HS-TA1: ROHS3 compliant).

Q: Are the package dimensions identical between PS2505L-2 and LTV-824HS-TA1?

A: Both parts use 8-SMD surface mount packages with gull wing leads. Physical footprint compatibility is maintained for PCB layout purposes.

Q: What is the isolation voltage rating, and is it the same across both parts?

A: Both the PS2505L-2 and LTV-824HS-TA1 provide 5000Vrms isolation voltage, meeting high-voltage isolation requirements in industrial and power conversion applications.

Q: Does the LTV-824HS-TA1 support both AC and DC input signals?

A: Yes, the LTV-824HS-TA1 supports both AC and DC input types, maintaining functional compatibility with the PS2505L-2 across input signal configurations.

Q: Why is the PS2505L-2 classified as obsolete?

A: The PS2505L-2 is classified as obsolete by the manufacturer, indicating discontinued production and limited availability. The LTV-824HS-TA1 represents an active alternative for new designs and production continuity.

Q: What compliance certifications apply to the LTV-824HS-TA1?

A: The LTV-824HS-TA1 is ROHS3 compliant and carries EAR99 export classification. The PS2505L-2 is RoHS non-compliant and REACH affected, presenting regulatory considerations for new applications.
