Substitute Part Grouping Explanation

Substitution of the PS2533L-1-F3-K-A is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Darlington
• Current Transfer Ratio: 1500% (Min) @ 1mA and 6500% (Max) @ 1mA
• Voltage - Output (Max): 350V
• Current - Output / Channel: 150mA
• Vce Saturation (Max): 1V
• Rise / Fall Time: 100µs, 100µs

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Supplier Device Package: 4-SMD

Environmental Parameters (Must Match):

• Operating Temperature: -55°C ~ 100°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are identified from the NEPOC series manufactured by Renesas Electronics Corporation. Packaging format (Tube vs. Tape & Reel) and REACH status represent secondary differentiators that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—PS2533L-1-A, PS2533L-1-F3-A, and PS2533L-1-V-F3-A—are parametrically equivalent to the PS2533L-1-F3-K-A across all critical electrical, mechanical, and environmental specifications. Selection among these alternatives is based on product status and supply chain considerations:

PS2533L-1-F3-A is the primary recommended substitute. This part maintains active product status with Renesas Electronics Corporation, offers the highest inventory availability (25400 units), and is supplied in Tape & Reel format suitable for automated assembly processes. REACH Unaffected status aligns with the original part specification.

PS2533L-1-V-F3-A serves as a secondary alternative with active status and substantial inventory (5300 units). This variant is also supplied in Tape & Reel format and maintains REACH Unaffected compliance.

PS2533L-1-A is available in Tube packaging with active product status and moderate inventory (2798 units). This option is suitable for applications where Tube packaging is acceptable. REACH Affected status differs from the original part and may require regulatory review depending on application jurisdiction.

All three substitutes are manufactured by Renesas Electronics Corporation within the NEPOC series and are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can PS2533L-1-F3-A be used as a direct replacement for PS2533L-1-F3-K-A?

A: Yes. PS2533L-1-F3-A is parametrically equivalent across all electrical, mechanical, and environmental specifications. The primary difference is packaging format (Tape & Reel vs. original specification) and manufacturer transition from CEL to Renesas Electronics Corporation. Both parts are ROHS3 compliant with identical isolation voltage (5000Vrms), output current (150mA), and operating temperature range (-55°C to 100°C).

Q: What is the difference between PS2533L-1-A and PS2533L-1-F3-A?

A: Both parts are electrically and mechanically identical. The primary distinction is packaging format: PS2533L-1-A is supplied in Tube packaging, while PS2533L-1-F3-A is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume automated assembly, whereas Tube packaging is used for lower-volume or manual assembly applications.

Q: Does the REACH Affected status of PS2533L-1-A affect compatibility?

A: REACH Affected status indicates regulatory classification but does not alter electrical or mechanical compatibility. Selection should consider application jurisdiction and regulatory requirements. For applications requiring REACH Unaffected compliance, PS2533L-1-F3-A or PS2533L-1-V-F3-A are appropriate alternatives.

Q: Are all substitute parts suitable for the same PCB layout?

A: Yes. All substitute parts share identical package specifications: 4-SMD, Gull Wing configuration with Surface Mount mounting type. PCB footprints, solder pad layouts, and assembly processes remain unchanged.

Q: What is the significance of the "V" designation in PS2533L-1-V-F3-A?

A: The "V" designation is a manufacturer variant code within the NEPOC series. This part maintains identical electrical and mechanical specifications to PS2533L-1-F3-A and is functionally interchangeable. The variant designation does not affect performance or compatibility.

Q: Which substitute part offers the best supply chain availability?

A: PS2533L-1-F3-A provides the highest inventory availability at 25400 units in stock. This part is recommended for applications requiring immediate procurement or high-volume orders.
