Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2562-1-L-A is determined by strict equivalence across the following critical parameters:

Isolation and Safety Characteristics: Voltage isolation rating of 5000Vrms is mandatory for maintaining electrical safety boundaries in the target application.

Output Configuration: Darlington output topology must be preserved to ensure compatibility with existing circuit designs and load characteristics.

Electrical Performance: Current transfer ratio range (700% to 3400% @ 1mA), maximum output voltage (40V), and maximum output current (200mA) define the functional operating envelope.

Switching Characteristics: Rise and fall times of 100µs establish the temporal response requirements for signal integrity.

Physical Form Factor: 4-DIP through-hole package with 0.300" (7.62mm) spacing is required for PCB compatibility and assembly processes.

Compliance Requirements: RoHS3 compliance and REACH applicability status must be maintained for regulatory adherence.

Parameter Comparison

Engineering Selection Recommendations

The PS2562-1-L-A manufactured by Renesas Electronics Corporation is a parametric equivalent substitute for the discontinued CEL PS2562-1-L-A optoisolator. All critical electrical, thermal, and mechanical specifications are identical across both parts.

Product Status Consideration: The Renesas variant maintains active product status, ensuring long-term availability and continued manufacturer support, whereas the CEL version is discontinued at DiGi Electronics.

Compliance Alignment: Both parts maintain identical RoHS3 compliance and REACH applicability status, satisfying regulatory requirements without modification to design documentation or supply chain processes.

Packaging Difference: The Renesas substitute is supplied in tube packaging, whereas the original CEL part packaging format is not specified. Tube packaging is standard for through-hole components and presents no functional or assembly incompatibility.

Inventory Availability: The Renesas variant demonstrates significantly higher inventory availability (4661 units versus 867 units), supporting procurement continuity and lead-time reduction.

Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2562-1-L-A directly replace the CEL PS2562-1-L-A in existing designs?

A: Yes. All electrical parameters, thermal specifications, and mechanical dimensions are identical. The 4-DIP through-hole package format is unchanged. Direct substitution is supported without circuit modification.

Q: Are there differences in isolation voltage performance between the two manufacturers?

A: No. Both parts specify 5000Vrms isolation voltage with identical electrical characteristics across the full operating temperature range of -55°C to 100°C.

Q: Does the tube packaging of the Renesas part affect assembly compatibility?

A: No. Tube packaging is a standard distribution format for through-hole components and does not affect PCB assembly, soldering processes, or functional performance.

Q: Are compliance certifications maintained with the Renesas substitute?

A: Yes. Both parts maintain ROHS3 compliance and REACH applicability status. No changes to regulatory documentation or supply chain qualification are required.

Q: What is the significance of the higher current transfer ratio range (700% to 3400%)?

A: This range defines the optoisolator's ability to transfer input current to the output stage. Both parts specify identical minimum and maximum values, ensuring equivalent switching performance and load-driving capability.

Q: Is the 100µs rise and fall time specification critical for substitution?

A: Yes. Rise and fall times determine signal integrity and switching speed in the application circuit. Both parts specify identical 100µs values, confirming temporal compatibility.
