Key Parameters

Substitute Part Grouping Explanation

Substitution of optoisolators is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Voltage isolation rating (5000Vrms required)
• Output type (Darlington configuration)
• Maximum output voltage (40V)
• Maximum output current per channel (200mA)
• Vce saturation characteristics (1V maximum)
• Operating temperature range (-55°C to 100°C)
• Input type (DC)

Mechanical Compatibility Criteria:

• Package type (4-DIP)
• Mounting method (Through Hole)
• Pin configuration and spacing

Regulatory Compliance:

• RoHS3 compliance
• REACH status
• Moisture sensitivity level

The substitute parts PS2562-1-A and PS2502-1-A share identical electrical specifications with the main part. However, PS2502-1-A and PS2562-1-A feature a 4-DIP package with 0.300" (7.62mm) spacing, differing from the PS2562L1-1-K-A's 0.400" (10.16mm) spacing. The PS2562L1-1-K-A maintains a higher current transfer ratio minimum of 2000% @ 1mA compared to 200% @ 1mA for the substitute parts, indicating enhanced input-to-output current gain characteristics.

Parameter Comparison

Engineering Selection Recommendations

PS2562-1-A (Renesas Electronics Corporation) is the primary substitute for the PS2562L1-1-K-A. This part maintains active product status and shares identical electrical specifications including 5000Vrms isolation, Darlington output configuration, 40V maximum output voltage, and 200mA output current capacity. Both parts comply with ROHS3 and REACH requirements. The PS2562-1-A is housed in a 4-DIP package with 0.300" (7.62mm) spacing, which differs from the main part's 0.400" (10.16mm) spacing. This package dimension difference requires PCB layout verification before implementation. The PS2562-1-A carries a current transfer ratio minimum of 200% @ 1mA, lower than the main part's 2000% specification, indicating reduced input-to-output current gain.

PS2502-1-A (Renesas Electronics Corporation) is a secondary substitute with identical electrical performance to PS2562-1-A. This part is classified as "Not For New Designs," limiting its suitability for new development projects. The PS2502-1-A shares the same 4-DIP package dimensions (0.300", 7.62mm) as PS2562-1-A and maintains full compliance with RoHS3 and REACH standards.

For applications requiring the higher current transfer ratio of 2000% @ 1mA, the PS2562L1-1-K-A remains the only available option among the listed parts. Substitution to PS2562-1-A or PS2502-1-A is electrically feasible for applications tolerating the lower 200% @ 1mA current transfer ratio, provided PCB layout accommodates the different package spacing.

Frequently Asked Questions (FAQ)

Q: Can PS2562-1-A directly replace PS2562L1-1-K-A without PCB modifications?

A: Electrical substitution is feasible. However, the PS2562-1-A uses a 4-DIP package with 0.300" (7.62mm) spacing compared to the PS2562L1-1-K-A's 0.400" (10.16mm) spacing. PCB layout verification is required to confirm pin hole compatibility and trace routing feasibility.

Q: What is the significance of the current transfer ratio difference between PS2562L1-1-K-A (2000%) and PS2562-1-A (200%)?

A: Current transfer ratio defines the ratio of output current to input current. The PS2562L1-1-K-A provides 10 times higher current gain at 1mA input current. Applications requiring minimal input current drive benefit from the higher ratio. Designs tolerating higher input current requirements can use PS2562-1-A without functional impact.

Q: Why is PS2502-1-A marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and support for this part. While electrically functional, PS2502-1-A is reserved for legacy system maintenance. New designs should prioritize PS2562-1-A, which carries active product status.

Q: Are all three parts RoHS3 and REACH compliant?

A: Yes. PS2562L1-1-K-A, PS2562-1-A, and PS2502-1-A are all ROHS3 compliant with REACH affected status. All parts carry moisture sensitivity level 1 (unlimited), indicating no special moisture handling requirements.

Q: What is the isolation voltage rating, and is it consistent across all parts?

A: All three parts maintain 5000Vrms isolation voltage rating. This specification is identical across PS2562L1-1-K-A, PS2562-1-A, and PS2502-1-A, ensuring equivalent isolation performance in high-voltage applications.

Q: Can these parts operate across the full -55°C to 100°C temperature range?

A: Yes. All three parts are rated for -55°C to 100°C operating temperature. This specification is consistent across PS2562L1-1-K-A, PS2562-1-A, and PS2502-1-A, supporting equivalent thermal performance in extended temperature environments.

Q: What are the key electrical parameters that must match for substitution?

A: Critical parameters for substitution include isolation voltage (5000Vrms), output type (Darlington), maximum output voltage (40V), maximum output current (200mA), Vce saturation (1V maximum), and operating temperature range (-55°C to 100°C). All listed parts meet these criteria. The current transfer ratio difference (2000% versus 200%) is the primary electrical distinction affecting circuit design.
