PS2535L-1-F3-A Equivalent & Substitute Parts

Part Overview

The PS2535L-1-F3-A is a 5000Vrms optoisolator with Darlington output, 1 channel, in 4-SMD surface mount packaging. This component provides galvanic isolation in DC input applications with a maximum output voltage of 350V and 120mA output current per channel. The main part number is currently discontinued at DiGi Electronics, making identification of compatible substitute components essential for design continuity and procurement planning. Substitutes are evaluated based on electrical isolation performance, output configuration, thermal operating range, and mounting compatibility.

Substitute Part Grouping Explanation

Substitution of the PS2535L-1-F3-A is determined by strict equivalence in electrical isolation voltage (5000Vrms), channel count (1 channel), output type classification (Darlington vs. Transistor variants), current transfer ratio range (400%-5500% @ 1mA), maximum output voltage (350V), and output current capacity (120mA per channel). All substitute parts maintain identical operating temperature range (-55°C to 100°C), input type (DC), and surface mount packaging (4-SMD, Gull Wing). Substitutes are grouped by output type: Darlington output variants (PS2535L-1-F3-A, PS2535L-1-A) and Transistor output variants (PS2535L-1-V-A, PS2535L-1-V-F3-A). Parts designated with "-F3-" suffix indicate Tape & Reel packaging; parts without this suffix are supplied in Tube packaging.

Parameter Comparison

Engineering Selection Recommendations

PS2535L-1-A from Renesas Electronics Corporation is the primary direct substitute for the discontinued PS2535L-1-F3-A, offering identical Darlington output configuration and electrical specifications. This part is maintained in active product status with 3915 units in stock. PS2535L-1-A is supplied in Tube packaging, whereas the original part number PS2535L-1-F3-A uses Tape & Reel format.

PS2535L-1-V-A and PS2535L-1-V-F3-A are parametric equivalents with Transistor output configuration rather than Darlington output. These components maintain all electrical isolation, current transfer ratio, voltage, and current specifications, with the primary distinction being output circuit topology. PS2535L-1-V-F3-A includes Tape & Reel packaging matching the original part's supply format.

All substitute components maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. Component selection depends on application requirement for Darlington versus Transistor output configuration and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Are Darlington and Transistor output variants interchangeable? A: Darlington and Transistor outputs are not directly interchangeable. Both variants meet identical isolation voltage (5000Vrms), current transfer ratio (400%-5500% @ 1mA), maximum output voltage (350V), and current capacity (120mA) specifications. Selection is determined by circuit topology requirements and output impedance characteristics required by the application.

Q: What is the difference between PS2535L-1-F3-A and PS2535L-1-A? A: The primary difference is packaging format. PS2535L-1-F3-A is supplied in Tape & Reel (TR) format, while PS2535L-1-A is supplied in Tube format. All electrical specifications, operating temperature range (-55°C to 100°C), and physical package configuration (4-SMD, Gull Wing) are identical. Component selection depends on procurement volume and assembly line compatibility requirements.

Q: Why does the parameter table show different manufacturers for the main part? A: The original PS2535L-1-F3-A is listed as CEL manufacture and is discontinued at DiGi Electronics. All active substitute parts are manufactured by Renesas Electronics Corporation under the PS2535 base product number family, ensuring design continuity with maintained electrical performance.

Q: Are all parts RoHS compliant? A: All listed parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. REACH compliance differs: PS2535L-1-A is REACH Affected, while PS2535L-1-F3-A, PS2535L-1-V-A, and PS2535L-1-V-F3-A are REACH Unaffected.

Q: What is the current transfer ratio range? A: All optoisolators in this family maintain a minimum current transfer ratio of 400% and maximum of 5500%, both measured at 1mA input current. This parameter specification is consistent across all part variants and determines the gain characteristics of the optoisolator output circuit.
