PS2502-1-L-A Equivalent & Substitute Parts

Part Overview

The PS2502-1-L-A is a single-channel optoisolator with Darlington output, rated for 5000Vrms isolation voltage. Manufactured by CEL in a 4-DIP package, this component provides galvanic isolation for DC signal applications requiring 200mA output current capability. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active or existing inventory sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2502-1-L-A is determined by the following critical electrical and mechanical parameters:

Isolation voltage requirement: 5000Vrms is mandatory for systems requiring this level of galvanic isolation.

Output configuration: Single-channel Darlington output with 200mA current capability and 40V maximum output voltage must be preserved.

Package form factor: 4-DIP (0.300", 7.62mm) through-hole mounting ensures mechanical and electrical compatibility in existing PCB designs.

Operating temperature range: -55°C ~ 100°C defines the acceptable temperature envelope for application environments.

Input/Output electrical characteristics: DC input type, Darlington output type, forward voltage (1.17V typical), and saturation voltage (1V maximum) ensure functional equivalence in signal isolation circuits.

The substitute parts PS2502-1-A, PS2562-1-A, and PS2562-1-V-A all maintain these critical parameters. These parts differ from the original in Current Transfer Ratio specifications and product status, but satisfy the isolation and output requirements of equivalent designs.

Parameter Comparison

Engineering Selection Recommendations

PS2502-1-A: Manufactured by Renesas Electronics Corporation with "Not For New Designs" status. This part shares the identical PS2502 base product number with the original and maintains full electrical equivalence across isolation voltage, output configuration, current ratings, and operating temperature range. ROHS3 compliance and unlimited MSL rating are preserved. Selection of this part addresses discontinuation while retaining the PS2502 platform characteristics.

PS2562-1-A: Manufactured by Renesas Electronics Corporation with Active product status. This part represents the current production alternative within the NEPOC optoisolator family. Full electrical equivalence is maintained across all critical parameters including 5000Vrms isolation, Darlington output, 200mA capability, and operating temperature range. Active status provides assurance of continued availability. ROHS3 compliance and unlimited MSL rating apply. The PS2562 base product number indicates a later generation within the optoisolator family.

PS2562-1-V-A: Manufactured by Renesas Electronics Corporation with Active product status. Electrical specifications are identical to PS2562-1-A. This variant designation indicates packaging or handling specification differences within the same electrical family. Active status ensures supply continuity. ROHS3 compliance and unlimited MSL rating apply.

For applications requiring long-term design stability, PS2562-1-A and PS2562-1-V-A are preferred due to Active product status and production continuity within the Renesas optoisolator portfolio.

Frequently Asked Questions (FAQ)

Q: Can PS2562-1-A or PS2562-1-V-A directly replace PS2502-1-L-A in existing circuits?

A: Yes. All three parts maintain identical voltage isolation (5000Vrms), output type (Darlington), maximum output voltage (40V), output current rating (200mA), forward voltage (1.17V), saturation voltage (1V), rise and fall times (100µs each), operating temperature range (-55°C ~ 100°C), and 4-DIP package form factor. Direct substitution is supported by these matched electrical and mechanical parameters.

Q: Why is the Current Transfer Ratio specification different?

A: Current Transfer Ratio specifications are provided for the original PS2502-1-L-A but not for PS2562 variants in the available data. This parameter does not affect substitution suitability, as the output current capability (200mA) is specified identically across all parts.

Q: What is the difference between PS2562-1-A and PS2562-1-V-A?

A: Both parts maintain identical electrical and mechanical specifications. The "-V-" designation variant indicates a distinction in packaging or handling specification, but this does not affect electrical functionality or substitution compatibility.

Q: Is the 4-DIP package identical for all parts?

A: Yes. All parts utilize 4-DIP (0.300", 7.62mm) through-hole package configuration. Pin-out and physical dimensions are compatible, supporting direct board-level substitution.

Q: Are compliance certifications consistent across substitute parts?

A: All parts are ROHS3 compliant, REACH affected, and rated for unlimited moisture sensitivity level (MSL 1). Regulatory compliance is maintained across all substitutes.
