PS2505-1-A Optoisolator Equivalent & Substitute Parts

Part Overview

The PS2505-1-A is a 5000Vrms isolation optoisolator with transistor output in 4-DIP package configuration. Manufactured by CEL, this component is classified as discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives. The part operates across AC and DC input types with single-channel isolation capability and 50mA output current per channel. Due to its discontinued status, substitute parts from active manufacturers are required for new procurement and ongoing system support.

Substitute Part Grouping Explanation

Substitute parts for the PS2505-1-A are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Active Status): PS2565-1-A, PS2565-1-V-A, PS2565-1Y-A, and PS2565-1Y-V-A from Renesas Electronics Corporation maintain identical isolation voltage (5000Vrms), package configuration (4-DIP), output type (transistor), maximum output voltage (80V), output current (50mA), saturation voltage (300mV), rise/fall times (3µs, 5µs), operating temperature range (-55°C ~ 100°C), and input type (AC, DC) specifications. These parts differ in current transfer ratio maximum specification (400% @ 5mA versus 600% @ 5mA) and product status classification.

Parametric Equivalent (Legacy Status): PS2505-1-A from Renesas Electronics Corporation represents the parametric equivalent with identical electrical specifications to the original CEL part, including current transfer ratio maximum of 600% @ 5mA. This part carries "Not For New Designs" status.

Substitution logic is based strictly on matching isolation voltage, package type, output configuration, thermal range, and mechanical form factor. All listed substitutes maintain ROHS3 compliance and MSL Level 1 rating.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: PS2565-1-V-A is the primary recommended substitute. This part carries active product status from Renesas Electronics Corporation with highest inventory availability (28987 pcs). It maintains all critical electrical parameters including 5000Vrms isolation, 50mA output current, 300mV saturation voltage, and -55°C to 100°C operating range. ROHS3 compliance and MSL Level 1 rating are confirmed. The current transfer ratio maximum of 400% @ 5mA is lower than the original 600% specification but remains within acceptable tolerance for standard optoisolator applications.

For Legacy System Support: PS2505-1-A from Renesas Electronics Corporation provides parametric equivalence with identical current transfer ratio specifications (600% @ 5mA). However, this part carries "Not For New Designs" status and should be used only for direct replacement in existing systems where the higher current transfer ratio is functionally required.

Alternative Active Options: PS2565-1-A and PS2565-1Y-V-A offer equivalent electrical performance with active status. PS2565-1-A provides standard NEPOC series designation. PS2565-1Y-A and PS2565-1Y-V-A variants are available with lower inventory levels (1108 and 1243 pcs respectively).

All substitute parts maintain identical package configuration (4-DIP through-hole), thermal operating range, and compliance certifications required for direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can PS2565-1-A directly replace PS2505-1-A in existing designs?

A: Yes. Both parts maintain identical isolation voltage (5000Vrms), package type (4-DIP), output current (50mA), saturation voltage (300mV), and operating temperature range (-55°C ~ 100°C). The primary difference is current transfer ratio maximum specification: PS2565-1-A specifies 400% @ 5mA versus PS2505-1-A at 600% @ 5mA. For applications where the lower current transfer ratio is acceptable, direct substitution is valid.

Q: What is the difference between PS2565-1-A and PS2565-1-V-A?

A: Both parts are electrically identical with matching isolation voltage, output specifications, and thermal range. The "-V-" designation indicates a variant classification. Both carry active product status and ROHS3 compliance. PS2565-1-V-A has significantly higher inventory availability (28987 pcs versus 8800 pcs).

Q: Why do PS2565-1Y-A and PS2565-1Y-V-A have lower inventory?

A: These variants carry lower stock levels (1108 and 1243 pcs respectively) compared to standard PS2565 variants. They maintain identical electrical and mechanical specifications but represent alternative product line designations within the Renesas NEPOC optoisolator family.

Q: Is the 4-DIP package compatible across all substitute parts?

A: Yes. All substitute parts use identical 4-DIP (0.300", 7.62mm) through-hole package configuration. PCB footprint and pin assignments are compatible for direct substitution without layout modifications.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. PS2565 variants carry REACH Unaffected status, while PS2505-1-A (Renesas) carries REACH Affected status. ECCN classification is EAR99 for all parts.

Q: Should I use PS2505-1-A (Renesas) for new designs?

A: No. PS2505-1-A from Renesas carries "Not For New Designs" status. This part should be reserved for legacy system maintenance only. PS2565-1-V-A is the recommended active substitute for new applications.

Q: Are there performance differences in switching speed between substitute parts?

A: No. All substitute parts specify identical rise and fall times of 3µs and 5µs respectively. Switching performance is equivalent across all listed alternatives.
