PS2702-1-F3 Optoisolator Equivalent & Substitute Parts

Part Overview

The PS2702-1-F3 is a Darlington output optoisolator with 3750Vrms isolation voltage, designed for single-channel signal isolation in surface mount applications. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production support and design continuity. Direct substitutes with identical electrical and mechanical specifications are available from the manufacturer as active products.

Substitute Part Grouping Explanation

Substitutes for the PS2702-1-F3 are identified based on electrical parameter equivalence and mechanical compatibility. All substitute parts maintain identical specifications across the following critical parameters: isolation voltage (3750Vrms), number of channels (1), output type (Darlington), current transfer ratio minimum (200% @ 1mA), maximum output voltage (40V), output current per channel (200mA), rise and fall times (200µs each), saturation voltage (1V maximum), operating temperature range (-55°C to 100°C), and surface mount package configuration (4-SMD, Gull Wing).

The PS2702-1-F3 series includes two active substitutes: PS2702-1-F3-A (direct manufacturer part with Tape & Reel packaging) and PS2702-1-V-F3-A (parametric equivalent with Tape & Reel packaging). Both are manufactured by Renesas Electronics Corporation and maintain full electrical and mechanical parameter compatibility with the obsolete original part.

Engineering Selection Recommendations

Both PS2702-1-F3-A and PS2702-1-V-F3-A are active substitutes with full electrical and mechanical parameter compatibility to the obsolete PS2702-1-F3.

PS2702-1-F3-A is the direct manufacturer part number replacement, maintaining the closest lineage to the original component. This part is ROHS3 compliant and REACH unaffected, addressing regulatory requirements where the original PS2702-1-F3 carried RoHS non-compliance and REACH affected status.

PS2702-1-V-F3-A is a parametric equivalent offering identical functional specifications with the same compliance improvements. Both parts are supplied in Tape & Reel packaging and maintain sufficient inventory for production support.

For applications where the original PS2702-1-F3 is no longer available, either substitute part provides full functional equivalence with improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can PS2702-1-F3-A and PS2702-1-V-F3-A be used interchangeably with the PS2702-1-F3?

A: Both substitute parts maintain identical electrical parameters including isolation voltage, output current, switching times, and operating temperature range. They use the same 4-SMD Gull Wing package configuration, making them functionally and mechanically interchangeable for all applications using the original PS2702-1-F3.

Q: What are the compliance differences between the original part and substitutes?

A: The original PS2702-1-F3 is RoHS non-compliant and REACH affected. Both PS2702-1-F3-A and PS2702-1-V-F3-A are ROHS3 compliant and REACH unaffected, providing improved environmental and regulatory compliance.

Q: What is the difference between PS2702-1-F3-A and PS2702-1-V-F3-A?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. PS2702-1-F3-A is the direct manufacturer replacement, while PS2702-1-V-F3-A is designated as a parametric equivalent. Both are active products with sufficient inventory and offer the same functional performance.

Q: Are both substitute parts available in the same packaging format?

A: Both PS2702-1-F3-A and PS2702-1-V-F3-A are supplied in Tape & Reel (TR) packaging, standard for production volumes. The original PS2702-1-F3 packaging format was not specified in available data.

Q: Which substitute part should be selected for new designs?

A: Either substitute is suitable for new designs. Selection may be based on part availability, pricing, or existing supply chain preferences, as both parts are functionally and mechanically equivalent with identical electrical specifications.
