PS2562L2-1-K-A Equivalent & Substitute Parts

Part Overview

The PS2562L2-1-K-A is a 5000Vrms isolation optoisolator with Darlington output, designed for single-channel DC input applications requiring high voltage isolation. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs. The NEPOC series alternative parts maintain the same electrical and mechanical specifications required for direct substitution in applications requiring optoisolation with Darlington output topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by equivalence across all electrical isolation parameters, output characteristics, and package specifications. The allowed parameters for substitution within this optoisolator category are:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Darlington
• Voltage - Output (Max): 40V
• Current - Output / Channel: 200mA
• Rise / Fall Time: 100µs, 100µs
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Operating Temperature Range: -55°C ~ 100°C

Two equivalent parts meet these substitution criteria: PS2502L-1-K-A (manufactured by Renesas Electronics Corporation) and PS2562L2-1-K-A (manufactured by Renesas Electronics Corporation). Both maintain identical electrical specifications and physical packaging requirements, enabling direct functional replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are actively manufactured and available, with current inventory levels exceeding 900 units. The PS2502L-1-K-A and Renesas-manufactured PS2562L2-1-K-A meet all electrical and mechanical requirements for direct replacement. Selection between substitutes is based on availability and procurement preference, as electrical performance and compliance certifications are identical. Both parts carry ROHS3 Compliance and REACH Affected designations, matching the original component specifications. The transition from the discontinued CEL-manufactured version to active Renesas alternatives ensures continuous supply for applications requiring 5000Vrms isolation with single-channel Darlington output.

Frequently Asked Questions (FAQ)

Q: Are PS2502L-1-K-A and PS2562L2-1-K-A (Renesas) electrically interchangeable with the original PS2562L2-1-K-A?

A: Yes. Both substitute parts meet all electrical and mechanical specifications: 5000Vrms isolation, 1-channel Darlington output, 200mA output current, 40V maximum output voltage, and 4-SMD package form factor. All three parts operate across the identical -55°C to 100°C temperature range.

Q: What is the primary difference between the substitute options?

A: The PS2502L-1-K-A and PS2562L2-1-K-A substitute differ by manufacturer designation and base product number (PS2502 versus PS2562). Electrical parameters and physical packaging are equivalent. The PS2502L-1-K-A uses Tube packaging; the PS2562L2-1-K-A packaging type is not specified in the provided parameters.

Q: Does switching to a substitute part require PCB layout modifications?

A: No. Both substitutes maintain the 4-SMD, Gull Wing package configuration with identical pin arrangement and electrical characteristics as the original PS2562L2-1-K-A.

Q: Are the RoHS and REACH compliance standards maintained in substitutes?

A: Yes. Both substitute parts are ROHS3 Compliant and REACH Affected, matching the original component designations.

Q: What is the Current Transfer Ratio significance for substitution?

A: Current Transfer Ratio of 2000% @ 1mA is a critical parameter defining the optical-to-electrical conversion efficiency. All three parts maintain this specification, ensuring identical drive capability and signal transmission characteristics in isolation circuits.
