Substitute Part Grouping Explanation

The PS2581L1-H-A qualifies as a parametric equivalent to the PS2561L1-1-H-A based on the following critical substitution criteria:

Electrical Parameters (Identical):

• Isolation voltage: 5000Vrms
• Number of channels: 1
• Current transfer ratio range: 80% to 160% @ 5mA
• Rise / fall time: 3µs, 5µs
• Output type: Transistor
• Maximum output voltage: 80V
• Output current per channel: 50mA
• Forward voltage (Typ): 1.17V
• Maximum DC forward current: 80mA
• Vce saturation (Max): 300mV
• Operating temperature range: -55°C ~ 100°C

Mechanical Parameters (Identical):

• Mounting type: Through Hole
• Package / case: 4-DIP (0.400", 10.16mm)

Compliance (Identical):

• RoHS3 Compliant
• REACH Affected
• MSL: 1 (Unlimited)

The primary difference is packaging format: PS2561L1-1-H-A is supplied without specified packaging, while PS2581L1-H-A is supplied in Tube packaging. Both parts share the same NEPOC series designation and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both PS2561L1-1-H-A and PS2581L1-H-A are active products from Renesas Electronics Corporation with identical electrical and mechanical specifications. Selection between these parts should be based on:

Packaging and Supply Considerations: PS2581L1-H-A is supplied in Tube packaging with 8404 units in stock, compared to PS2561L1-1-H-A with 629 units. Tube packaging may be preferred for automated assembly processes or high-volume production runs.

Compliance Status: Both parts maintain ROHS3 compliance, REACH affected status, and MSL Level 1 (Unlimited), making them suitable for equivalent applications without additional qualification requirements.

Electrical Performance: No performance differentiation exists between the two parts. Both deliver identical isolation voltage, current transfer ratio, switching characteristics, and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can PS2581L1-H-A be used as a direct replacement for PS2561L1-1-H-A?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The primary difference is packaging format (Tube vs. unspecified). Direct substitution is valid for circuit design and performance.

Q: What is the difference between these two part numbers?

A: The PS2581L1-H-A is supplied in Tube packaging, while the PS2561L1-1-H-A packaging format is not specified in the product data. All electrical characteristics, isolation ratings, switching performance, and thermal specifications are identical.

Q: Are there any compatibility concerns when switching between these parts?

A: No compatibility concerns exist. Both parts use the same 4-DIP through-hole package with identical pin configuration and electrical behavior. PCB layout and circuit design remain unchanged.

Q: Which part should I select for new designs?

A: Selection should be based on supply availability and packaging requirements. PS2581L1-H-A offers higher inventory (8404 units) and Tube packaging, which may be advantageous for production planning. Both parts are active and suitable for new designs.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts share identical MSL Level 1 (Unlimited) moisture sensitivity classification, requiring no special moisture control during storage or handling.
