Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2561L-1-V is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Current Transfer Ratio range: 80% to 400% @ 5mA
• Rise / Fall Time: 3µs, 5µs
• Input Type: DC
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Voltage - Forward (Vf): 1.17V
• Current - DC Forward (If) (Max): 80mA
• Vce Saturation (Max): 300mV
• Operating Temperature: -55°C ~ 100°C

Mechanical Parameters (Must Match):

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

All substitute parts listed maintain identical electrical and mechanical specifications. Differences exist only in manufacturer, product status, packaging format (Tube vs. Tape & Reel), and compliance certifications.

Engineering Selection Recommendations

For Existing Designs (Maintenance & Repair):

Direct substitutes PS2561L-1-F3-A, PS2561L-1-V-A, PS2561L-1-V-F3-A, PS2561L-1-A, and PS2581L2-A are electrically and mechanically equivalent to PS2561L-1-V. All substitute parts are manufactured by Renesas Electronics Corporation and maintain identical electrical performance across isolation voltage, current transfer ratio, output characteristics, and operating temperature range.

Packaging Format Selection:

• Tape & Reel (TR) Format: PS2561L-1-F3-A and PS2561L-1-V-F3-A are suitable for automated assembly processes requiring continuous reel feeding.
• Tube Format: PS2561L-1-V-A, PS2561L-1-A, and PS2581L2-A are suitable for manual assembly, repair operations, and lower-volume applications.

Compliance Considerations:

All Renesas substitute parts are ROHS3 compliant, addressing environmental and regulatory requirements. The original PS2561L-1-V is RoHS non-compliant. Selection of ROHS3-compliant alternatives aligns with current manufacturing standards and regulatory frameworks.

Product Status Impact:

The original part is classified as Obsolete. All substitute parts are classified as Not For New Designs, indicating limited long-term availability. For new product development, evaluation of current-generation optoisolator families is recommended, though these substitutes remain suitable for legacy system support.

Frequently Asked Questions (FAQ)

Q: Can PS2561L-1-F3-A replace PS2561L-1-V in existing circuit designs?

A: Yes. PS2561L-1-F3-A is a direct electrical and mechanical equivalent. Both components share identical isolation voltage (5000Vrms), current transfer ratio (80% to 400% @ 5mA), output current rating (50mA), saturation voltage (300mV), and operating temperature range (-55°C ~ 100°C). The primary difference is packaging format: PS2561L-1-F3-A is supplied in Tape & Reel format, while PS2561L-1-V packaging format is not specified in available data.

Q: What is the difference between PS2561L-1-V-F3-A and PS2561L-1-F3-A?

A: Both parts are electrically identical with 5000Vrms isolation, 1 channel, and 50mA output current. The designation difference reflects internal Renesas product line management. PS2561L-1-V-F3-A has higher inventory availability (25,100 pcs) compared to PS2561L-1-F3-A (4,468 pcs). Both are supplied in Tape & Reel format and are ROHS3 compliant.

Q: Should I select Tube or Tape & Reel packaging?

A: Selection depends on assembly method. Tape & Reel format (PS2561L-1-F3-A, PS2561L-1-V-F3-A) is optimized for automated pick-and-place assembly. Tube format (PS2561L-1-V-A, PS2561L-1-A, PS2581L2-A) is suitable for manual assembly, repair, and prototyping. Electrical performance is identical across both packaging formats.

Q: Is PS2581L2-A a suitable substitute?

A: Yes. PS2581L2-A is a parametric equivalent with identical electrical specifications: 5000Vrms isolation, 80% to 400% current transfer ratio, 50mA output current, and -55°C ~ 100°C operating temperature. The base product number differs (PS2581 vs. PS2561), but all critical electrical and mechanical parameters match. It is supplied in Tube format and is ROHS3 compliant.

Q: What compliance certifications apply to substitute parts?

A: All Renesas substitute parts (PS2561L-1-F3-A, PS2561L-1-V-A, PS2561L-1-V-F3-A, PS2561L-1-A, PS2581L2-A) are ROHS3 compliant. The original PS2561L-1-V is RoHS non-compliant. REACH status varies: PS2561L-1-F3-A and PS2561L-1-V-F3-A are REACH Unaffected; PS2561L-1-V-A, PS2561L-1-A, and PS2581L2-A are REACH Affected. All parts carry ECCN classification EAR99 and HTSUS code 8541.49.8000.

Q: Are these parts suitable for new product designs?

A: All substitute parts are classified as Not For New Designs. For new product development, current-generation optoisolator components from Renesas or alternative manufacturers should be evaluated. These substitutes are appropriate for legacy system maintenance, repair, and design continuation of existing products.
