Parameter Comparison

Engineering Selection Recommendations

The PS2533L-1-A and PS2533L-1-V-A are direct parametric equivalents to the PS2533L-1-K-A. Both substitute parts are manufactured by Renesas Electronics Corporation and maintain active product status, ensuring long-term availability and supply chain continuity.

Selection Basis:

Both substitute parts satisfy all electrical performance requirements, mechanical specifications, and regulatory compliance standards. The primary distinction between the two substitutes is packaging format (both supplied in Tube configuration), with no impact on functional performance or circuit integration.

The substitutes demonstrate superior inventory availability compared to the discontinued PS2533L-1-K-A, with PS2533L-1-V-A offering the highest stock level at 2999 pieces.

All three parts maintain identical RoHS3 compliance, REACH affected status, and export classification (EAR99), ensuring regulatory alignment across procurement and deployment scenarios.

Frequently Asked Questions (FAQ)

Q: Can PS2533L-1-A or PS2533L-1-V-A be used as direct replacements for PS2533L-1-K-A in existing designs?

A: Yes. Both substitute parts are parametric equivalents with identical electrical specifications, isolation voltage, output current capacity, temperature range, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between PS2533L-1-A and PS2533L-1-V-A?

A: Both parts are electrically and mechanically identical. The difference is limited to packaging format; both are supplied in Tube configuration. No functional or performance distinction exists between these two substitutes.

Q: Are the substitute parts compatible with the original 4-SMD, Gull Wing package footprint?

A: Yes. Both PS2533L-1-A and PS2533L-1-V-A use the identical 4-SMD, Gull Wing package type and Surface Mount configuration as the PS2533L-1-K-A. PCB layout and assembly processes require no modification.

Q: Do the substitute parts maintain the same isolation voltage rating?

A: Yes. All three parts maintain 5000Vrms isolation voltage. The current transfer ratio range (1500% to 6500% @ 1mA), maximum output voltage (350V), and maximum output current (150mA) are identical across all variants.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: No. All three parts are ROHS3 compliant, REACH affected, classified as EAR99, and share the same HTSUS code (8541.49.8000). Regulatory and compliance status is uniform across all variants.

Q: What is the moisture sensitivity level for these optoisolators?

A: All three parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements during storage and handling.

Q: Which substitute part should be selected for new procurement?

A: Both PS2533L-1-A and PS2533L-1-V-A are suitable for new procurement. Selection may be based on inventory availability, supplier preference, or existing supply chain relationships. Both maintain active product status and equivalent long-term availability.
