PS2502L-1-A Equivalent & Substitute Parts

Part Overview

The PS2502L-1-A is a 5000Vrms isolation optoisolator with Darlington output configuration, manufactured by CEL in a 4-SMD surface mount package. This component is classified as discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives from current manufacturers. The part operates across a temperature range of -55°C to 100°C and delivers 200mA output current with a 200% minimum current transfer ratio at 1mA input.

Substitute parts are required due to the discontinued status of the original PS2502L-1-A. Active alternatives maintain identical electrical specifications and mechanical compatibility while offering continued availability and supply chain reliability.

Electrical Equivalence Criteria:

• Voltage isolation: 5000Vrms
• Output configuration: Darlington
• Current transfer ratio: 200% minimum @ 1mA
• Maximum output voltage: 40V
• Output current capacity: 200mA per channel
• Rise and fall time: 100µs typical
• Vce saturation: 1V maximum
• Operating temperature range: -55°C to 100°C
• Input type: DC
• Forward voltage: 1.17V typical
• Maximum DC forward current: 80mA

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Package configuration: 4-SMD, Gull Wing
• Supplier device package: 4-SMD

All substitute parts listed are manufactured by Renesas Electronics Corporation and are classified as active products with current availability. Substitutes differ only in packaging format (Tape & Reel or Tube) and REACH compliance status, which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts—PS2562L-1-F3-A, PS2562L-1-V-F3-A, PS2562L-1-V-A, PS2562L2-1-A, and PS2562L2-1-V-A—are direct electrical and mechanical equivalents to the PS2502L-1-A. Each substitute maintains identical isolation voltage, output configuration, current transfer ratio, and thermal operating range.

Product Status Consideration: All substitute parts carry active product status from Renesas Electronics Corporation, ensuring continued manufacturing and supply availability. The original PS2502L-1-A is discontinued, making substitution necessary for new designs and ongoing production requirements.

Compliance and Certification: All substitute parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), matching the original part's environmental specifications. REACH compliance differs between substitutes: PS2562L-1-F3-A, PS2562L2-1-A carry REACH Affected status, while PS2562L-1-V-F3-A, PS2562L-1-V-A, and PS2562L2-1-V-A are REACH Unaffected.

Packaging Format Selection: Substitute selection depends on procurement and assembly requirements. Tape & Reel (TR) packaging is suitable for high-volume automated assembly operations. Tube packaging accommodates lower-volume or manual assembly processes. Electrical and mechanical performance remains identical across all packaging formats.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically identical to the PS2502L-1-A?

A: Yes. All substitute parts maintain identical electrical specifications including 5000Vrms isolation voltage, 200% minimum current transfer ratio at 1mA, 40V maximum output voltage, 200mA output current capacity, and -55°C to 100°C operating temperature range.

Q: What is the difference between the substitute parts?

A: Substitute parts differ in packaging format and REACH compliance status. PS2562L-1-F3-A is supplied in Tape & Reel format. PS2562L-1-V-A, PS2562L2-1-A, and PS2562L2-1-V-A are supplied in Tube format. REACH compliance varies: PS2562L-1-F3-A and PS2562L2-1-A are REACH Affected; PS2562L-1-V-F3-A, PS2562L-1-V-A, and PS2562L2-1-V-A are REACH Unaffected. All other electrical and mechanical parameters are identical.

Q: Can the PS2562L-1-F3-A be used in place of the PS2502L-1-A in existing designs?

A: Yes. The PS2562L-1-F3-A is a direct substitute with identical electrical specifications and 4-SMD Gull Wing package configuration. The only difference is packaging format (Tape & Reel versus the original format), which does not affect circuit performance or PCB assembly compatibility.

Q: What is the significance of the "-V-" designation in part numbers PS2562L-1-V-F3-A, PS2562L-1-V-A, and PS2562L2-1-V-A?

A: The "-V-" designation indicates a specific variant within the PS2562 series. This designation does not alter electrical specifications or mechanical compatibility. All parts with and without the "-V-" designation maintain identical isolation voltage, output current, and operating temperature range.

Q: Are there inventory differences between substitute parts?

A: Yes. Inventory levels vary: PS2562L-1-F3-A has 1286 units, PS2562L-1-V-F3-A has 22365 units, PS2562L-1-V-A has 3095 units, PS2562L2-1-A has 1229 units, and PS2562L2-1-V-A has 3419 units. Inventory availability should be confirmed with the supplier for specific procurement timelines.

Q: Which substitute part should be selected for high-volume automated assembly?

A: PS2562L-1-F3-A in Tape & Reel (TR) packaging is optimized for high-volume automated pick-and-place assembly operations. Tube packaging alternatives are suitable for lower-volume or manual assembly processes.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), matching the environmental specifications of the original PS2502L-1-A.
