Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2701-1-V-F3-Y-A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Isolation voltage rating: 3750Vrms
• Number of channels: 1
• Output configuration: Transistor output
• Current transfer ratio range: 50% to 300% @ 5mA
• Maximum output voltage: 40V
• Maximum output current per channel: 80mA
• Rise and fall time specifications: 3µs and 5µs
• Operating temperature range: -55°C to 100°C
• Surface mount configuration
• RoHS3 compliance

The PS2701-1-F3-A manufactured by Renesas Electronics Corporation meets all mandatory electrical and mechanical parameters. Both parts belong to the NEPOC series and maintain identical functional specifications. The primary difference is packaging designation (4-SMD Gull Wing vs. 4-SOP) and supplier device package classification, which do not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PS2701-1-F3-A from Renesas Electronics Corporation is a direct functional equivalent to the discontinued PS2701-1-V-F3-Y-A. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The original PS2701-1-V-F3-Y-A is discontinued at DiGi Electronics, making the PS2701-1-F3-A the appropriate alternative for new procurement and ongoing production support.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications subject to environmental and hazardous substance restrictions.

Electrical Equivalence: Complete parameter matching across isolation voltage, output characteristics, current transfer ratio, and timing specifications ensures direct circuit compatibility without design modification.

Availability: The PS2701-1-F3-A maintains significantly higher inventory levels (355,200 pieces) compared to the original part (952 pieces), providing supply chain reliability for production applications.

Packaging Consideration: While the supplier device package designation differs (4-SOP vs. 4-SMD), both maintain identical 4-SMD Gull Wing physical configuration and surface mount compatibility, ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can PS2701-1-F3-A be used as a direct replacement for PS2701-1-V-F3-Y-A in existing designs?

A: Yes. The PS2701-1-F3-A meets all electrical and mechanical specifications of the original part. No circuit design changes are required. Both components share identical isolation voltage, output current rating, current transfer ratio range, and operating temperature specifications.

Q: What is the difference between the 4-SMD and 4-SOP package designations?

A: Both designations refer to the same physical 4-SMD Gull Wing surface mount package. The supplier device package classification reflects manufacturer documentation conventions and does not indicate different physical dimensions or pin configurations.

Q: Are there any compliance differences between the two parts?

A: No. Both PS2701-1-V-F3-Y-A and PS2701-1-F3-A maintain identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory requirements are fully satisfied by either component.

Q: What determines whether a substitute optoisolator is acceptable?

A: Substitution requires matching across isolation voltage rating, number of channels, output type, current transfer ratio specifications, maximum output voltage and current, timing characteristics, operating temperature range, and compliance certifications. Any deviation in these parameters requires design re-evaluation.

Q: Why is the PS2701-1-F3-A preferred despite the original part having lower inventory?

A: The PS2701-1-F3-A is manufactured by Renesas Electronics Corporation, a major semiconductor supplier with established production capacity and supply chain infrastructure. The significantly higher inventory level (355,200 pieces) ensures consistent availability for production schedules and reduces procurement risk.

Q: Can the PS2701-1-F3-A be used in applications requiring the exact original manufacturer?

A: Component selection should be based on electrical and mechanical specifications rather than manufacturer preference, provided all parameters match and compliance requirements are met. The PS2701-1-F3-A satisfies all functional requirements of the original specification.
