Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2706-1-F3-A optoisolator is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 3750Vrms isolation rating is the primary electrical specification that defines the component's safety and functional capability.

Channel Configuration: Single-channel (1 Channel) architecture must be maintained for circuit compatibility.

Output Configuration: Darlington output type is essential for the intended switching and amplification characteristics.

Current Transfer Ratio: Minimum 200% @ 1mA establishes the optical coupling efficiency and input-to-output signal transfer capability.

Output Electrical Ratings: Maximum output voltage of 40V and output current of 200mA define the load-driving capability.

Input Compatibility: AC and DC input type acceptance ensures flexibility in signal source integration.

Switching Characteristics: Rise and fall times of 200µs each specify the temporal response of the component.

Package and Mounting: 4-SMD Gull Wing surface mount package ensures mechanical and electrical compatibility with existing PCB designs.

Environmental and Compliance: Operating temperature range of -55°C to 100°C, RoHS3 compliance, and MSL Level 1 rating establish reliability and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The PS2706-1-F3-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL PS2706-1-F3-A. Both components share identical electrical specifications, package configuration, and environmental ratings.

Product Status Consideration: The CEL version is discontinued at DiGi Electronics, whereas the Renesas Electronics version maintains active product status. This distinction is significant for long-term component availability and supply chain continuity.

Compliance and Certification: Both versions maintain ROHS3 compliance, REACH Unaffected status, and EAR99 export classification. MSL Level 1 rating indicates unlimited shelf life under standard storage conditions.

Packaging and Logistics: The Renesas version is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility for both prototype and production volume requirements.

For applications currently using the CEL PS2706-1-F3-A, direct substitution with the Renesas Electronics PS2706-1-F3-A is electrically and mechanically compatible without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the Renesas Electronics PS2706-1-F3-A directly replace the CEL PS2706-1-F3-A in existing designs?

A: Yes. Both components are parametrically identical across all specified electrical, thermal, and mechanical parameters. No circuit redesign or PCB modification is required for direct substitution.

Q: What is the significance of the identical part number across different manufacturers?

A: The PS2706-1-F3-A designation indicates a standardized component specification within the NEPOC series. Both CEL and Renesas Electronics manufacture components to this specification, ensuring cross-manufacturer compatibility.

Q: Are there any differences in packaging options between the two manufacturers?

A: The Renesas Electronics version is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Packaging selection does not affect electrical or mechanical performance and is determined by procurement and assembly requirements.

Q: What parameters must remain constant for substitution eligibility?

A: Isolation voltage (3750Vrms), channel count (1), output type (Darlington), current transfer ratio (200% @ 1mA minimum), output voltage rating (40V), output current (200mA), package type (4-SMD Gull Wing), and operating temperature range (-55°C to 100°C) must all match exactly.

Q: Is the Renesas Electronics version suitable for new design implementations?

A: Yes. The active product status of the Renesas Electronics PS2706-1-F3-A makes it suitable for both replacement applications and new design implementations where the specified electrical and environmental parameters are required.

Q: How does MSL Level 1 rating affect component handling?

A: MSL Level 1 indicates unlimited shelf life. The component does not require special moisture control during storage or handling, simplifying logistics and inventory management compared to higher MSL ratings.
