PS2805C-1-F3-M-A Optoisolator Equivalent & Substitute Parts

Part Overview

The PS2805C-1-F3-M-A is a 2500Vrms isolation optoisolator with transistor output, manufactured by CEL in a 4-SOIC surface mount package. This component is classified as discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives. The part operates across a temperature range of -55°C to 100°C and supports both AC and DC input types with a single isolated channel configuration. Substitute parts must maintain identical electrical isolation, switching characteristics, and mechanical compatibility to ensure direct replacement capability in existing circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the PS2805C-1-F3-M-A is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Isolation: 2500Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Current Transfer Ratio range: 50% to 400% @ 5mA (mandatory match)
• Turn On / Turn Off Time: 10µs, 7µs (mandatory match)
• Rise / Fall Time: 5µs, 7µs (mandatory match)
• Output Type: Transistor (mandatory match)
• Voltage - Output (Max): 80V (mandatory match)
• Current - Output / Channel: 30mA (mandatory match)
• Vce Saturation (Max): 300mV (mandatory match)
• Operating Temperature: -55°C ~ 100°C (mandatory match)

Mechanical Equivalence Criteria:

• Package / Case: 4-SOIC (0.173", 4.40mm Width) (mandatory match)
• Mounting Type: Surface Mount (mandatory match)

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant (mandatory match)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory match)

All three substitute parts meet these criteria and are manufactured by Renesas Electronics Corporation with active product status.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—PS2805C-1-F3-A, PS2805C-1-V-A, and PS2805C-1-V-F3-A—are manufactured by Renesas Electronics Corporation and maintain active product status. Each substitute achieves full parametric equivalence with the discontinued PS2805C-1-F3-M-A across all electrical, mechanical, and compliance specifications.

PS2805C-1-F3-A is recommended as the primary substitute due to highest inventory availability (75,100 pieces) and identical packaging designation (Cut Tape & Digi-Reel).

PS2805C-1-V-A provides an alternative with active status and adequate inventory (5,396 pieces), supplied in Strip packaging format.

PS2805C-1-V-F3-A offers a third option with active status and inventory of 4,445 pieces.

All three alternatives satisfy ROHS3 compliance and MSL Level 1 requirements, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can PS2805C-1-F3-A directly replace PS2805C-1-F3-M-A in existing designs?

A: Yes. PS2805C-1-F3-A maintains identical electrical parameters (2500Vrms isolation, 1 channel, 50-400% CTR @ 5mA, 10µs/7µs switching times), identical mechanical specifications (4-SOIC package, surface mount), and identical compliance certifications (ROHS3, MSL 1). Direct substitution is supported without circuit modification.

Q: What is the difference between PS2805C-1-F3-A, PS2805C-1-V-A, and PS2805C-1-V-F3-A?

A: All three parts are parametrically equivalent. Differences exist only in packaging format and inventory levels. PS2805C-1-F3-A is supplied in Cut Tape & Digi-Reel format with highest availability. PS2805C-1-V-A is supplied in Strip format. PS2805C-1-V-F3-A is supplied without specified packaging format. All three use identical 4-SOIC (0.173", 4.40mm Width) mechanical packages.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. All substitute parts match the main part across isolation voltage, channel count, current transfer ratio, switching characteristics, output voltage/current ratings, saturation voltage, operating temperature range, package dimensions, mounting type, and compliance certifications.

Q: Which substitute part should be selected for new production orders?

A: PS2805C-1-F3-A is the recommended selection for new production due to superior inventory availability (75,100 pieces) and standard Cut Tape & Digi-Reel packaging format, which aligns with typical high-volume manufacturing workflows.

Q: Do all substitute parts meet the same environmental and compliance standards?

A: Yes. All three substitute parts are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (Unlimited moisture sensitivity), matching the compliance profile of the original PS2805C-1-F3-M-A.
