PS2562-1-A Optoisolator 5KV Darlington Output

Part Overview

The PS2562-1-A is a 5000Vrms optoisolator with Darlington output in a 4-DIP package, designed for galvanic isolation of digital and analog signals in industrial and power management applications. The original manufacturer part (CEL) is discontinued at DiGi Electronics, requiring identification of active alternative sources that maintain identical electrical and mechanical specifications. Renesas Electronics Corporation currently manufactures direct equivalents that provide full functional interchangeability while maintaining product availability and supply continuity.

• Voltage - Isolation: 5000Vrms isolation specification
• Number of Channels: Single channel configuration
• Output Type: Darlington output topology
• Package / Case: 4-DIP (0.300", 7.62mm) physical footprint
• Mounting Type: Through Hole for PCB assembly
• Current Transfer Ratio: Minimum 200% @ 1mA
• Voltage - Output (Max): 40V maximum output voltage capability
• Current - Output / Channel: 200mA maximum output current
• Operating Temperature Range: -55°C ~ 100°C
• Input Type: DC input signal
• RoHS Compliance: ROHS3 Compliant status

All qualified substitutes maintain identical electrical performance characteristics and physical package dimensions, ensuring direct pinout and schematic compatibility without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

For new designs and active product development: Select PS2562-1-A or PS2562-1-V-A manufactured by Renesas Electronics Corporation. Both parts carry Active product status and ensure long-term supply continuity. PS2562-1-A offers greater inventory depth with 4453 units in stock, while PS2562-1-V-A provides an alternative source with 994 units available.

For existing inventory or legacy system maintenance: PS2502-1-A manufactured by Renesas Electronics Corporation is electrically identical and mechanically compatible. This part carries "Not For New Designs" status, limiting its suitability to replacement and repair applications where supply of original specifications is the priority.

Compliance and certifications: All qualified substitutes maintain ROHS3 compliance and REACH Affected status, ensuring regulatory acceptability in regulated markets and applications requiring hazardous substance restriction compliance.

Frequently Asked Questions (FAQ)

Q: Can I use PS2502-1-A in place of PS2562-1-A in new product designs?

A: No. While PS2502-1-A is electrically and mechanically equivalent, it carries "Not For New Designs" product status. For new designs, use PS2562-1-A or PS2562-1-V-A, both manufactured by Renesas with Active product status.

Q: Are there physical footprint differences between these optoisolators?

A: No. All substitutes use identical 4-DIP (0.300", 7.62mm) package dimensions with through-hole mounting, ensuring direct drop-in replacement without PCB layout modifications.

Q: What determines electrical interchangeability between these parts?

A: These optoisolators are interchangeable based on matching 5000Vrms isolation voltage, single-channel Darlington output configuration, 200% minimum current transfer ratio, 40V maximum output voltage, 200mA maximum output current, 100µs rise and fall times, and -55°C to 100°C operating temperature range.

Q: Do all substitutes meet RoHS and REACH requirements?

A: Yes. All listed parts carry ROHS3 Compliant status and REACH Affected designation, meeting regulatory requirements for restricted substance content in regulated market segments.

Q: Which substitute should I select for maximum supply availability?

A: PS2502-1-A provides the highest inventory depth with 25100 units in stock. However, for new designs, PS2562-1-A (4453 units) is preferred due to its Active product status and manufacturer long-term commitment to continued production.
